The profitability of a commercial vehicle workshop stands and falls with complete cost accounting, transparent KPIs and consistent margin management. This guide first shows the five steps to full cost accounting. It also explains key figures for contribution margin management and acquisition approaches for the B2B commercial vehicle business. In addition, Alltrucks modules such as Assist24, Alltrucks Fleet and industry and service partner co-operations supplement the company's own levers.

  • Full cost accounting in 5 steps
  • Three key figures: Productivity, efficiency, contribution margin
  • ≥10 % entrepreneurial profit as minimum target
What you will learn in this guide
Systematically building profitability instead of hoping for it

This guide summarises the economic management logic from the practice of the Alltrucks partner network. It is therefore aimed at workshop owners and managers who do not want to run their commercial vehicle workshop „on instinct“, but on the basis of reliable key figures - from the minimum hourly rate and contribution margin calculation to targeted growth through new customer groups.

  • How to calculate your minimum hourly rate according to full cost accounting
  • How to systematically raise your hourly rate to a full-cost basis - and justify it on the market

What really characterises a profitable commercial vehicle workshop?

The profitability of the commercial vehicle workshop is not a question of gut feeling. Rather, it is a combination of reliable key figures, costing and strategic management. However, the reality is often different: Many workshop owners know what they are realising. However, they do not know what actually remains as profit. This results in businesses that work well operationally but fall short of their economic potential.

Cost itemShareOptimisation approach
Personnel costs48 to 55 per centProductivity and capacity utilisation
Parts and material18 to 24 per centFramework agreements and identical parts
Room costs and energy9 to 12 per centLED and heating control
Depreciation of equipment7 to 10 per centLife cycle planning
IT and software3 to 5 per centCloud consolidation

A pattern from industry practice: The most profitable workshops are not necessarily the largest or those with the most orders. Rather, they are the ones who know their key figures, measure them regularly and derive decisions from them. Hourly rate levels and margins are therefore the result of systematic work on the right parameters.

The three key figures that decide everything

Three key figures form the foundation of every economically sound commercial vehicle workshop. If you don't know them, you are steering blind. Those who know them, on the other hand, can intervene in a targeted manner - and often with surprisingly small adjustments.

  • Productivity: Hours sold divided by available attendance hours. Target value for profitable operations: at least 75 per cent. In concrete terms, this means that 6 hours out of 8 hours of attendance should be billable. Companies under 65 %, on the other hand, have structural problems in Order planning or workshop organisation.
  • Efficiency: Actual working time used in relation to the target time. A value above 100 % means: faster than calculated. Well-organised companies achieve noticeably higher values here than the industry average - usually thanks to clean acceptance processes, structured checklists and consistent timesheet reviews.
  • Contribution margin (DB): What remains of an order after deducting the variable costs. Only when the DB per order type is known is it possible to judge which orders are really worthwhile.
Frequent findings from practice

„In the independent commercial vehicle workshop sector, a significant proportion of businesses do not calculate their hourly rates to cover costs. The most common mistakes: underestimating overheads, ignoring non-productive times, not passing on price increases.“

- Observation from the Alltrucks partner network

The break-even analysis - do you know your figure?

The break-even analysis answers the most important question of everyday workshop life: How many invoiced hours per month are your fixed costs covered? Anything above that is profit. In practice, this shows that a workshop with four mechanics and 22 working days per month typically requires around 5 to 6 billable hours per mechanic per day until the break-even point is reached. Every additional hour thereafter directly improves the margin.

The break-even analysis also shows how sensitively profitability reacts to changes: An hourly rate increase of a few per cent noticeably lowers the break-even - in the typical model by several dozen hours per month. An additional mechanic, on the other hand, increases the billable hours, but also the fixed costs. Anyone who plays through this starting point understands the economic mechanics of their own business.

Three ways to increase sales - without new customers

Many workshop owners equate increasing turnover with acquiring new customers. There are three approaches that are at least as effective and cost significantly less: increase productivity (every additional billable hour per mechanic per day increases the monthly turnover by a full hourly rate times 22 working days - per mechanic), noticeably increase the average order value through systematic upselling and calculate the parts margin in a differentiated manner (significantly higher mark-ups can be applied to specialised components than to standard parts).

Practical Insight: In the industry, the most important differentiator between profitable and unprofitable companies is rarely the hourly rate. Rather, it is the realisation of the hourly rate: how much of the work performed is actually invoiced. In terms of methodology, full cost accounting and hourly rate calculation are also based on the principles of VDI 2895 (Organisation of maintenance) on. Their life cycle cost analysis in turn adopts the definitions from DIN EN 13306 (maintenance terms). The most important adjusting screw is therefore the daily timesheet review by the workshop manager - a practice that is not yet consistently practised in many independent commercial vehicle workshops according to industry observations from motor vehicle trade associations.

How do you go from market price to full cost accounting?

The hourly rate is the central adjusting screw for the profitability of every commercial vehicle workshop. Nevertheless, in most companies it is not based on a solid calculation. Instead, it is based on what the competition charges, what the tax consultant has recommended or - even more frequently - on what has „always been the case“. The result: a significant proportion of commercial vehicle workshops work below their minimum hourly rate. In a typical case, this shortfall is well below the cost-covering rate. With around 1,500 invoiced hours per mechanic per year, this adds up to a substantial annual profit that goes unnoticed.

The three most common calculation errors

  • Billable hours overestimated: 2,080 full-time hours sounds tempting. But after deducting holidays (240 hours), public holidays (80 hours), sickness (96 hours), training (40 hours) and non-productive time, the realistic figure is 1,400 to 1,550 billable hours per mechanic per year. Anyone calculating with 2,000 hours is therefore spreading their costs over too many hours.
  • Overheads forgotten: Tool depreciation, IT, DMS licences, insurance, accountants, training, work clothing, waste disposal - these items make up a considerable block of overheads per mechanic per year. Anyone who does not include them is therefore calculating a hidden shortfall.
  • No profit mark-up: An hourly rate that only covers costs is not a sustainable business model. Therefore, at least 8-12 per cent profit mark-up 15 % if investments are to be made.

The 5-step method of full cost accounting

The following method is applicable to commercial vehicle workshops of any size. Firstly, take an afternoon to analyse your BWA and cost statements:

  • Step 1 - Recording personnel costs: Gross wages, nationally regulated social security contributions, statutory accident insurance, company pension scheme, training costs, work clothing. In real terms, the full costs per mechanic are around 50-55 % above the gross wage.
  • Step 2 - Allocate overheads: Rent/lease, energy, insurance, IT, DMS, diagnostic equipment licences, advertising. Divided by productive employees, this results in a substantial block of fixed costs per mechanic.
  • Step 3 - Calculate billable hours: 2,080 minus holidays, public holidays, sickness, training, minus non-productive time (75 % productivity ratio). Realistic: 1,400-1,500 billable hours/year.
  • Step 4 - Define profit mark-up: At least 10 % of the total costs. This profit is required for reserves, investments and the entrepreneurial risk.
  • Step 5 - Calculate minimum hourly rate: (personnel costs + overheads + profit mark-up) / billable hours. The result is your absolute minimum.
Three factors that facilitate price enforcement

„Ultimately, the hourly rate level is a function of three factors: reliable full cost accounting, clear competence signals on the market (certifications, brand coverage, documentation) and consistent price communication. Those who systematically build up the three building blocks argue their price from their own cost structure - not from a comparison with the competition.“

- Practical observations from the Alltrucks partner network

Enforcing the price on the market

A solid calculation is useless if the price cannot be realised. Therefore, three proven drivers help: Communicating value instead of defending price (Multi-brand expertise with the Alltrucks Multi-brand diagnosis / Alltrucks KTS Truck V3, certification as a multi-brand system technician via Alltrucks training level 1/2/3, warranty, digital documentation), Use network affiliation as a competence signal (workshop finder, Alltrucks marketing tools) and Communicate price increases professionally (at least 4 weeks in advance, objective justification, emphasise countervalue). With moderate, objectively justified hourly rate increases, experience has shown that the loss of customers is minimal. This is because the margin gained usually more than compensates for it.

Practical Insight: The hourly rate calculation must separate two components: the productive hourly rate (mechanic labour costs + social security contributions + workplace costs) and the administrative hourly rate (management, accounting, marketing, insurance). The proportion of administrative overheads is also considerable in the commercial vehicle workshop industry. Anyone who does not take this into account is therefore structurally working below full costs. Established calculation guidelines for commercial vehicle workshops therefore recommend a three-pillar structure: basic wage value + workshop overheads (rent, energy, tools) + administrative overheads + risk costs + entrepreneurial profit. Those who calculate on a full-cost basis raise their hourly rate level recognisably above the industry average. Those who remain below this level, on the other hand, are cross-financing their customers.

Where is 15 to 20 per cent savings potential hidden?

Cutting costs sounds like sacrifice and loss of quality. In reality, however, the opposite is true: those who know their cost structure and optimise it in a targeted manner create financial scope for better equipment, higher wages and investments. In most commercial vehicle workshops, there is therefore potential for savings of 15 to 20 per cent - not by cutting costs, but by eliminating waste, renegotiating overpriced contracts and optimising processes.

Degree of specialisationTypical adjusting screwIndicative return on sales
Universal basic servicesUtilisation, processes, acceptance quality8 to 12 per cent
Multi-brand system expertiseDiagnostic penetration, full cost calculation10 to 15 per cent
High-voltage E-truck serviceHV qualification, investment protection12 to 18 per cent
ADAS calibrationCertification, calibration environment, brand coverage12 to 18 per cent

Rule of thumb for the cost structure of a commercial vehicle workshop: 50-60 % is accounted for by personnel, 20-30 % by materials and parts, 10-15 % by space costs and energy, 5-10 % by administration and miscellaneous. Experience has shown that the greatest savings potential lies in not in the largest cost block (personnel), but in materials and energy - because this is where optimisation takes place least often.

The three biggest cost drivers

  • Unproductive staff time: Reducing personnel costs does not mean cutting wages. Rather, the real starting point lies in productivity. The industry average is typically below the target value of 75 %. Every percentage point of additional productivity per mechanic therefore corresponds to noticeable additional added value per year - without additional personnel costs.
  • Parts purchasing at list prices: Many workshops buy parts at conditions that are significantly above the market average. The main reasons for this are: no framework agreements, too many individual orders, no systematic price comparison. Alltrucks partners, on the other hand, can take advantage of network conditions - please contact us for the specific details.
  • Energy costs: A typical commercial vehicle workshop with 600-1,000 m² of hall space consumes 80,000-150,000 kWh of electricity and 100,000-200,000 kWh of gas per year. The biggest factors here are: compressed air leaks (often 20-30 % of the compressed air consumption), LED conversion of the hall lighting, intelligent heating control with zone separation.

Quick wins without investment

Not every saving requires money. Here are three immediate measures that cost nothing and take effect immediately: Check insurance policies for overlaps and excessive amounts of cover, compare electricity and gas tariffs with current market offers, cancel unused software subscriptions and service contracts. Together, these three measures often bring a noticeable annual saving in the fixed cost block - without changing an operation.

Intelligent warehousing control

An overfilled warehouse ties up capital and causes costs for space, insurance and shrinkage. An empty warehouse, on the other hand, leads to rush orders and waiting times. The solution therefore lies in the ABC analysis: A-parts (high consumption) in stock, B-parts (medium consumption) with short delivery times from the wholesaler, C-parts (infrequent consumption) only order-related. Optimised inventory management thus reduces capital commitment by 20-30 % while at the same time increasing availability.

Save strategically when purchasing spare parts

The purchase of spare parts is one of the biggest cost drivers of all. Here are the most important levers: Framework agreements with the most important suppliers (who account for the majority of the purchasing volume), conscious choice of Quality level (OE / OEM / high-quality aftermarket - for many wear parts, identical parts of the same quality are noticeably cheaper than OE parts), Structured access to the parts catalogue (Alltrucks VINcat via the chassis number to identify the exact part version) as well as the Digitisation of the purchasing process (time savings in purchasing run into hours per year). Alltrucks partners can also take advantage of additional network conditions with selected industry partners.

Investments that reduce costs

„A modern diagnostic device that noticeably shortens the troubleshooting process recoups a significant number of mechanic hours per year when used regularly. Converted at the standard market hourly rate, the return usually significantly exceeds the investment sum - amortisation is typically achieved in the first to second year of operation.“

- Practical observations from the Alltrucks partner network

Practical Insight: The largest cost block in a commercial vehicle workshop after labour costs is parts purchasing - typically just under a third to a good third of turnover. Structured purchasing processes (framework agreements, clear quality levels, Alltrucks VINcat for VIN-based parts identification) are therefore the most important starting point here. In addition, Alltrucks partners can utilise network conditions; the specific conditions can be agreed with us. A second underestimated effect is energy optimisation: LED hall lighting with daylight control noticeably reduces operating costs and usually pays for itself within a few years. In addition, subsidies can be obtained through national funding programmes.

Why is not every order equally profitable?

Documentation of the work carried out on the lorry

Full order books are good - but not every order is equally profitable. Some order types generate an excellent contribution margin, while others barely cover their costs. But as long as you are not measuring this, you are flying blind. The contribution margin per order type is the direct lever for the profitability of the commercial vehicle workshop. However, a significant proportion of commercial vehicle workshops do not recognise this value - and thus forfeits the opportunity to control the order mix in a targeted manner.

The good news is that a noticeable increase in DB is realistic for most companies - without a single extra customer or an additional platform. Instead, it is sufficient to make existing orders more profitable: through better costing, targeted upselling, optimised use of materials and conscious management of the order mix.

DB I and DB II - understanding the two stages

  • DB I: Revenue minus variable costs (material, productive labour costs, order-dependent external services). A reliable DB-I target rate results from the company's own full cost calculation - generalised industry rates, on the other hand, are misleading because order type, material share and productive hourly rate vary per company.
  • DB II: Also takes into account the attributable fixed costs (pro rata platform costs, tool wear, pro rata energy, diagnostic licence costs) - this is the true profitability of the order.

DB II is therefore the key figure you should use to manage your order mix. A sensible internal orientation: the DB I per invoiced hour should be at least equal to the company's own productive hourly rate. If it is lower, the order does not cover its attributable costs. Workshops with clean acceptance, clear calculation and consistent mix control also achieve noticeably better DB values than without this discipline, depending on the type of order - the effect adds up over the year without additional work, simply through a better mix.

Five factors for increasing DB

  • Reduce material usage rate: Top workshops are recognisably below the industry average. Even a few percentage points less material usage therefore noticeably increases the annual DB.
  • Systematic upselling on acceptance: If the service technician discovers worn brake discs during the incoming inspection, this is not sales pressure - it is customer service. The additional brake job also typically contributes a DB I in the region of half a daily rate.
  • Check target times: Adjust every six months based on actual times. If work regularly takes longer than calculated, money is lost.
  • Promote order bundling: Combining several jobs in one workshop visit reduces pro rata fixed costs - the set-up time saving alone also results in around 20-30 minutes of additional DB-carrying output per bundled job.
  • Identify unprofitable orders: Order types with DB I per hour below the cost-covering rate should be scrutinised - either increase the price, make the process more efficient or consciously reduce it.
Practical tip

„Introduce simple DB tracking for four weeks. Make a note for each order: revenue, cost of materials, productive working time. After four weeks, you will have enough data to identify your most and least profitable order types. This overview alone is often the trigger for significant improvements. For acceptance and order structuring, the Alltrucks Technology Team a consistent guideline; the introduction - please feel free to contact us.“

- Practical observations from the Alltrucks partner network

Consciously controlling the order mix

The consequence of the DB analysis is not to only accept diagnostic orders. Rather, it is important to consciously manage the order mix: Use maintenance orders as a basis for basic capacity utilisation, but expand the proportion of high-margin orders (diagnostics, major repairs) in a targeted manner. In addition, consistently look for upselling opportunities for low-margin orders. This turns an average workshop into a profitably managed workshop - with the same employees, the same platforms and the same customers.

Practical Insight: In practice, the contribution margin per hour varies greatly depending on the type of order. Simple basic work such as the preparation of periodic technical monitoring (EU 2014/45), on the other hand, are significantly below the high-margin orders from diagnostics, engine repair and ADAS calibration. Those who specifically shift their order mix towards the high-margin areas therefore gain a noticeable additional DB share of annual turnover. In concrete terms, this means maintaining the volume of audit preparation for basic capacity utilisation and actively acquiring diagnostics and ADAS. A „diagnostic price advantage“ has also proved its worth - a flat rate for the initial diagnosis that is charged for subsequent repairs - this lowers the customer's inhibition threshold and secures the high-margin order for the workshop.

How does professional acquisition work in the B2B commercial vehicle business?

Analysis to improve workshop efficiency

Customer acquisition for commercial vehicle workshops works differently than in the car sector. While private individuals choose their garage based on proximity and Google ratings, fleet managers, haulage companies and fleet managers make their decision based on tough criteria: Availability, multi-brand expertise, response time and network coverage. If you want to grow, you need an acquisition strategy that is tailored to the logic of commercial customers.

The target group is also significantly smaller than in the passenger car market, but each individual customer is considerably more valuable economically. A haulier with 50 lorries who comes to you regularly can therefore mean a six-figure annual turnover. This therefore changes the entire acquisition logic.

The most effective acquisition channels in order of priority

  • Network visibility and co-operation: As an Alltrucks partner, you can be found in the Europe-wide workshop finder and receive access to specific sales modules of the network - e.g. Assist24 (24/7 breakdown service control), Alltrucks Fleet (fleet programme) and established collaborations with industry partners. We will be happy to discuss together which of these modules make sense for your company.
  • Actively promote recommendations: Experience has shown that recommendations are the most important new customer channel for independent commercial vehicle workshops. Recommendations are the result of consistently good work, transparent communication and reliable adherence to deadlines - and should therefore be actively sought.
  • Online visibility (Google Business Profile): A significant proportion of commercial garage searches now start online. Workshops with a well-maintained profile and a reliable number of good ratings will therefore receive Significantly more contact requests than companies without an active profile.
  • Direct approach of the top fleets: Firstly, identify the largest fleet operators in your catchment area and contact their fleet managers directly. Score points with concrete arguments: Multi-brand expertise, short Service life, transparent cost structure, network coverage.

Marketing for commercial vehicle workshops - what really works

In the B2B environment, large social media campaigns on Instagram or TikTok are of little use. Instead, sober, targeted measures are worthwhile: Google Business Profile meticulous maintenance (complete information, quick response to reviews), Website as proof of expertise (certifications, brand coverage, network affiliation) and LinkedIn instead of Instagram (networking with fleet managers, regular specialist articles, industry communication).

What network membership actually contributes

As an Alltrucks partner, you are visible in the Europe-wide workshop finder and can also use network modules such as Assist24 (breakdown service control), Alltrucks Fleet (fleet programme) and established cooperations. Which of these modules make economic sense for your company and which conditions apply can therefore be clarified individually in dialogue with us.

From new customer to regular customer - the first 90 days

It is significantly cheaper to retain an existing customer than to acquire a new one. This is why the conversion from new customer to regular customer is the decisive effect for sustainable growth. The first three orders in particular are decisive: personal greeting, proactive status updates, follow-up call after the initial order, offer for maintenance contract. Experience has shown that workshops that live this process consistently achieve a noticeably higher first-year retention rate than those without structured onboarding.

Marketing budget with a sense of proportion

The rule of thumb is 2-4 % of annual turnover for marketing and customer acquisition. However, the biggest leverage lies not in the advertising budget, but in network affiliation and excellent work that generates recommendations - and also in the targeted maintenance of existing customer relationships.

Visibility as a growth factor

Visibility, international recognition and a strong reputation make it easier to gain new customers and build trust. As an Alltrucks partner, your workshop will therefore stand out - visible on key platforms, supported by professional signage and the positive image of the Alltrucks brand and its founders. In addition to increased visibility, the Alltrucks network gives you direct access to vehicle and system manufacturers throughout Europe - and thus to new growth and business opportunities. At the same time, Alltrucks helps your workshop to work more efficiently and cost-effectively. By networking with industry partners and suppliers at attractive conditions, operating costs can be sustainably reduced.

Concretely usable in day-to-day business: the Alltrucks module Branding and visibility and the Marketing construction kit in the Alltrucks Partner Portal - with ready-made templates for local advertising, social media and public image that can be implemented without your own marketing department.

Practical Insight: The customer acquisition cost (CAC) in the commercial vehicle B2B market varies greatly depending on the region, competitive density and marketing mix. At the same time, the Customer Lifetime Value (CLV) of an average fleet customer is extraordinarily high over several years - the CAC/CLV ratio is therefore one of the most attractive marketing ratios in the commercial vehicle sector. Despite this, only a few independent commercial vehicle workshops invest in structured B2B acquisition at all. The starting point therefore lies in the definition of measurable acquisition KPIs: Number of initial calls per month, lead-to-order conversion, average first order value and repurchase rate after 6 months. Workshops that consistently track these values on a monthly basis thus manage their growth based on facts rather than gut instinct.

Frequently asked questions

What is the appropriate hourly rate for a commercial vehicle workshop?

This depends on your individual costs - a generalised answer would be dubious. Therefore, calculate your minimum hourly rate according to the 5-step method of full cost accounting in Chapter 02. Workshops that work well below their full costs are cross-financing their customers. Anything below the calculated minimum rate is therefore self-exploitation. The hourly rate that is viable for your business is determined by your own cost structure. If necessary, we will categorise this in a joint discussion - please contact us.

How do I calculate my costs correctly - and which ones are most often forgotten?

The full cost calculation includes personnel costs (gross wages plus nationally regulated social security contributions), overheads (rent, energy, IT, DMS, insurance, tool depreciation, accountants, advertising) and a profit mark-up of at least 10 %. Most often forgotten are also: tool depreciation, software licences, training costs, work clothing and disposal costs. These items form a substantial block of overheads per mechanic per year. Nevertheless, a significant proportion of companies do not include them in their hourly rates.

What return on sales is realistic for a commercial vehicle workshop?

A sustainably healthy return on sales is in the range of 8-12 per cent. Companies with too low a margin, on the other hand, have hardly any financial room for manoeuvre for investments, reserves or crises. Industry experience shows: Bigger is not necessarily more profitable. Organisation and cost discipline are more important than the size of the business.

How quickly do growth and acquisition strategy measures pay off?

The duration of effect varies greatly depending on the channel: Google Business and online visibility typically show initial results after 3-6 months. Direct sales to fleets, on the other hand, typically have a lead time of 6-12 months, but then deliver high-quality regular customers. The most important effect is also the conversion from new customer to regular customer in the first 90 days. This is because structured onboarding, proactive status updates and follow-up calls significantly improve the retention rate. Alltrucks modules such as Assist24, Alltrucks Fleet and the service partner co-operations with BPW (industry partner) have a complementary effect. We will be happy to discuss which ones are right for your company.
