The verdict in three sentences
For a firm of 10 motor engineers receiving 400 instructions a month, off-the-shelf vehicle assessment software costs 8,400 to 20,400 GBP a year and covers the basics if your workflow is standard. A custom build, 26,000 to 52,000 GBP as a 2026 ballpark with 3 to 5 months of development, makes sense when you want to deliver reports in 48 hours instead of 5 days and climb your work providers' rankings. Most of the gain comes from admin time removed: retyping between the instruction, the estimate, the photos and the final PDF.
The life of an instruction and where time leaks
An assessment always follows the same path: instruction received from the insurer or claims management company, appointment with the policyholder or body shop, inspection on site or by images, repair estimate, report writing, submission, then fee invoicing. In many firms each step lives in a different tool: the work provider's portal, a shared calendar, the estimating system, a photo folder on the engineer's phone, a Word template and the accounts package.
The cost shows up in minutes: 10 minutes to copy instruction data, 15 minutes to sort and rename photos, 20 minutes to assemble the report. Across 400 instructions, 45 minutes of retyping equals 300 hours a month, nearly two admin roles. And every day of delay hits the service score the insurer gives its panel firms, and therefore next quarter's volume.
Modules that take you from 5 days to 48 hours
| Step | Without an integrated tool | With custom software | Time saved per instruction |
|---|---|---|---|
| Instruction intake | Retyped from the insurer portal | Automatic import, file created | 10 min |
| Appointment | Manual calls and texts | Booking link sent to the policyholder | 8 min |
| Photos | Transferred from phone, renamed | Captured in the app, sorted by damage area | 15 min |
| Estimate | Separate entry in the estimating system | Vehicle data sent, result imported back | 7 min |
| Report | Assembled in Word | PDF generated with estimate, photos and findings | 20 min |
| Submission and billing | Email, then invoice keyed separately | Upload to the portal, automatic fee note | 5 min |
Total losses deserve their own module. Category S and N decisions carry specific steps, salvage handling and notification duties, and a tool that drafts letters and tracks deadlines avoids costly liability slips. The same goes for pre-accident valuations, which are more defensible when backed by a valuation history kept by the firm.
Off-the-shelf or custom: comparison
| Criterion | Off-the-shelf software | Custom build |
|---|---|---|
| Cost | 70 to 170 GBP per engineer per month, i.e. 8,400 to 20,400 GBP a year for 10 engineers | 26,000 to 52,000 GBP, then 5,000 to 10,000 GBP a year |
| Four-year total | 33,600 to 81,600 GBP | 46,000 to 92,000 GBP |
| Time to go live | 2 to 6 weeks | 3 to 5 months |
| Insurer portal links | Depends on vendor agreements | Built around your own work providers |
| Report template | Standard templates | Your branding plus each insurer's requirements |
| Offline mobile app | Varies | Designed for body shops and car parks with no signal |
| Turnaround dashboard | Basic | Delay by insurer, by engineer, by claim type |
Custom is not always cheaper over four years. It wins when your top three work providers send more than 60% of instructions and score your turnaround, or when you also handle non-insurance work (fleets, leasing returns, disputes) that standard tools fit badly. At Kolonell, such a project sits in the medium application grid, 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), or the complex grid, 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR), depending on the number of connectors, with scope set in the quote.
Mini case study
James, director of a 10-engineer assessment firm in Birmingham, receives 400 instructions a month at an average fee of 105 GBP, i.e. 42,000 GBP of monthly revenue. His average report turnaround is 5 days and two insurers have flagged a falling service score.

He commissions a custom build at 40,000 GBP plus 8,000 GBP a year of maintenance. Admin time per instruction drops from 45 to 15 minutes: 400 x 30 minutes, 200 hours a month freed. At 24 GBP loaded cost for an administrator, that saves 4,800 GBP a month, 57,600 GBP a year. With turnaround down to 48 hours, one insurer sends 15% more work: 60 instructions x 105 GBP, i.e. 6,300 GBP a month. Total yearly gain: 133,200 GBP. First-year cost: 48,000 GBP. Payback in a little over 4 months.
FAQ
Can the software receive instructions straight from insurers?
Yes, if the work provider's portal offers a data feed or integration interface. Scoping checks each one; plan 1 to 3 weeks of development per connector.
Do we have to drop our current estimating system?
No. The custom software sends vehicle data to the estimating system and pulls the result back. You keep the manufacturer data and labour times you already pay for.
How does an engineer work in a body shop with no signal?
The mobile app stores photos and notes offline, then syncs when the network returns. An assessment with 30 to 40 photos weighs around 60 to 120 MB.
Do reports meet each insurer's requirements?
Each insurer can have its own template, mandatory sections and attachment format. The software picks the right template on intake, which avoids the 5 to 10% of reports sent back for correction.
How long until we are live?
Plan 3 to 5 months, including 3 weeks of scoping and a month of testing with 2 or 3 engineers before rolling out to the whole firm.
