The verdict in three sentences
For a multi-brand dealership with 14 service bays in Berlin, custom service department software costs 25,000 to 55,000 EUR excl. VAT in 2026: online booking, digital repair orders, approval of additional work by SMS and integration with the DMS. The realistic goal is to lift bay occupancy from 72% to 88% without hiring. With 14 bays, those 16 points of occupancy are worth several hundred thousand euros of billed labour per year.
Where a workshop loses revenue
In most workshops, bays are not empty for lack of customers but for lack of coordination: poorly sized appointments, vehicles stuck waiting for customer approval, parts ordered too late. The table below summarises typical losses observed in a 14-bay workshop, 2026 order of magnitude.
| Source of loss | Without a tool | With dedicated software | Estimated impact |
|---|---|---|---|
| Phone bookings | 35% of calls missed at peak times | Online booking 24/7 | +8 to 12% bookings |
| Additional work quotes | Customer approval in 4 h on average | SMS approval in 25 minutes | 1.5 bay hours freed per affected RO |
| Paper repair orders | 10 minutes of re-keying per RO | Digital RO on tablet | 2 h per day saved at reception |
| Unplanned parts | 18% of ROs blocked waiting for parts | Pre-order at booking | -60% blockages |
| Customer no-shows | 9% of appointments | SMS reminders D-1 and H-2 | No-shows down to 3% |
| Technician scheduling | Whiteboard | Schedule by skill and by bay | Occupancy 72% to 88% |
Detailed budget by module
Workshop software does not replace the DMS (stock, invoicing, manufacturer accounting); it adds a modern operational layer on top. Here is the pricing by module.
| Module | Content | 2026 budget excl. VAT |
|---|---|---|
| Online booking | Service packages per brand, slots per bay and skill | 5,000 to 9,000 EUR |
| Digital repair order | Tablet check-in, photos, customer signature | 5,000 to 10,000 EUR |
| Additional work by SMS | Approval link, technician photos and video | 3,500 to 7,000 EUR |
| Workshop planner | Bay view, drag and drop, delay alerts | 4,000 to 9,000 EUR |
| DMS integration | Sync of customers, vehicles, ROs and parts | 5,000 to 14,000 EUR |
| Aftersales dashboard | Occupancy, hours sold, average ticket | 2,500 to 6,000 EUR |
A core "booking, digital RO, SMS" scope is delivered in 8 to 10 weeks for about 25,000 EUR excl. VAT. The full version with planner and two-way DMS integration reaches 45,000 to 55,000 EUR over 4 to 5 months. Hosting and maintenance cost 400 to 900 EUR excl. VAT per month, plus about 0.07 EUR per SMS sent.
Custom or off-the-shelf modules
Major DMS vendors offer add-on modules at 150 to 400 EUR per month per site, often per brand. In a multi-brand dealership, these modules rarely cover every brand with the same customer journey. Custom makes sense when you want one journey regardless of brand, and data you own.
Mini case study
Marc, aftersales director of a multi-brand dealership in Berlin, runs 14 bays open 8 hours a day, 230 days a year, i.e. 25,760 available bay hours. At 72% occupancy he sells 18,547 hours. At 88% he sells 22,669, i.e. 4,122 additional hours.

At an average labour rate of 95 EUR excl. VAT, the potential labour gain reaches 391,590 EUR per year, before associated parts sales. Even keeping only a third of that gain to be cautious, 130,000 EUR, software at 48,000 EUR excl. VAT pays back in under five months.
FAQ
How much does custom service department software cost?
For a dealership with 10 to 20 bays, expect 25,000 to 55,000 EUR excl. VAT in 2026. The spread depends mainly on the depth of DMS integration, 5,000 to 14,000 EUR.
Does the software replace our DMS?
No, it connects to it. The DMS remains the reference for invoicing and stock; the workshop software handles the customer journey and scheduling, syncing every 5 minutes or in real time depending on the available API.
Is SMS approval of quotes legally valid?
Yes, a timestamped approval through a unique link, tied to the customer's number and the amount, is proof of acceptance. The record is kept for at least 5 years.
How quickly do technicians adopt the tool?
Usually 2 to 3 weeks, with half a day of training per team. Tablet ROs cut re-keying from the first week.
What occupancy gain is realistic?
Going from 72% to 85 or 88% in 6 months is achievable if the planner and SMS quotes are used systematically. Each occupancy point is worth about 24,000 EUR of labour per year across 14 bays.
