01Verdict up front
The strongest reason is urgency. A workshop may need authority on the day a vehicle already occupies a ramp, and The Motor Ombudsman's current code requires accredited garages to contact the customer before additional work begins. This supports a paid test, not a build.
02The idea as understood
An adviser enters technician-approved findings, options, VAT-inclusive price and ETA. The service turns those approved facts into a clear customer update, lets the customer accept, decline or request a call, timestamps the decision and keeps an unresolved queue. Diagnosis, roadworthiness, safety, parts and labour choice, price, warranty, complaints, ETA and approval to send stay human-led.
Commercial hypothesis: £149–£249 for a two-week pilot, then £950–£1,750 setup and £199–£399 per month.
Gaps: bay count, existing GMS, eligible-job volume, baseline delays and calls, retention period and preferred channel are not yet known.
Prior work: the supplied St Helens assessment ranked the idea 91.6/100 and proposed a 20-job pilot. It is one INFERENCE signal only and does not feed the factor scores.
03Buyer and trigger
Buyer
Owner-manager or service adviser in a roughly 2–8 bay independent UK repair and MOT workshop. The bay range is an inference to test.
Trigger
A technician finds additional work and the vehicle cannot progress until the customer authorises or declines the finding, price and timing.
Current workaround
Calls, voicemail, email, text or WhatsApp, recorded in paper, job cards, spreadsheets, a GMS or staff memory.
Consequence
Ramp delay, lost work, status calls and a billing or trust dispute when scope and authority are unclear.

Objections: stopping for authority can force reassembly and another ramp slot; diagnostic effort may already have been authorised; an accept button without scope and context could worsen rather than resolve disputes.
Communities observed: r/AskMechanics, r/CarTalkUK, r/LegalAdviceUK, MoneySavingExpert consumer rights, and Garage Wire's trade forum. Garage Wire reports 1,863 topics, but targeted searches found no fresh relevant peer thread or usable posting rules. A May 2024 UK Business Forums thread about systems being too complicated is historical and excluded from scoring.
05Kill list
Disconfirming evidence was searched for deliberately.
| Finding against the idea | Seriousness | Implication |
|---|---|---|
| Exact functionality is crowded and cheap. Focused approval starts at £39/month; broader systems include it below £100. | High | Do not sell generic approval software. Test managed setup and a measured outcome beside the current GMS. |
| Trust can be harmed. Recent disputes contest diagnosis, extra work and implied authority; stale trade discussion warns VHCs can become pressure selling. | High | Keep judgement human, show agreed scope and VAT-inclusive price, and include call-back. |
| Adoption friction can erase value. A 2 October 2024 TechMan review reports a clunky interface, glitches and scheduling disruption; older workshop language says complex tools go unused. The fetch was search-mediated, so confidence is capped at Medium. | Medium | No GMS migration. Measure use on at least 80% of eligible pilot jobs. |
| Buyer acquisition is unproven. Relevant owner communities are fragmented, partly private or not visibly open to promotion. | Medium | Start with permission-aware direct local outreach and referrals. |
| A timestamp is not complete assurance. Identity, access, retention, delivery and correction are untested. | Medium | Minimise data, log both approvals and retain a manual fallback. |
No credible recent shutdown of an exact competitor or fresh target-buyer “just use a spreadsheet” thread was found. Live competing products are the stronger disconfirming evidence.
06Competitor and incumbent map
| Option | Price | Competitive finding |
|---|---|---|
| Servisly | £39–£59/month | Focused inspection and authority beside existing tools. Directly undercuts the proposition. |
| AutoChain | £69.99 + VAT; SMS £15 | Broader GMS with VHC and approvals; no setup fee. |
| BOOKAR | £99.99 + VAT | Full GMS with authorisation requests, photos and VHC. |
| Garage Hive | From £145/month | Mature approval flow and community, but broader and potentially complex. |
| GarageRevs Growth | £252 monthly or £210 annual | Similar price band, but includes a complete GMS. |
| TechMan | Plan-dependent | Exact workflow and ramp-space positioning; one recent review reports complexity and disruption. |
| Do nothing / phone, paper, WhatsApp, spreadsheet | £0 incremental software; staff time unknown | Familiar and flexible, but prone to missed calls, scattered records and disputed scope. |
| Authorise & Update | £149–£249 pilot; £950–£1,750 setup; £199–£399/month | Only differentiated if managed setup beside the current GMS measurably releases ramps or reduces calls. |
07Score breakdown
| Factor | Weight | Score | Justification |
|---|---|---|---|
| Pain evidence | 25 | 2 | Official volume, a current duty and several recent disputes, but not ten independent last-12-month buyer complaints with quantified cost. |
| Urgency | 20 | 3 | Authority can stop same-day work and hold ramp capacity; one thread gives a 2–3 hour example. |
| Buyer reach | 20 | 1 | Local garages are identifiable, but no public 1,000+ target-member channel with permissive posting rules was verified. |
| Manual pilot | 20 | 3 | Browser form, adviser review, existing SMS/email and a spreadsheet queue can deliver the outcome this week. |
| Price clue | 15 | 2 | Visible spend exists, but the proposed service does not undercut most exact incumbents. Its managed premium is unproved. |
08Proposed test design
Offer
Two-week, 20-job managed pilot for £149–£249. Clear updates, accept/decline/call-back and one waiting queue, beside the current GMS.
Commitment action
Pay for the pilot and nominate one adviser to supply approved facts. Praise or an unpaid interview is not a strong commitment.
First channel
Permission-aware direct outreach to the seven local garages in the prior assessment, then local referrals. Recheck status, decision-maker, GMS and contact permissions.
Gate rationale
Keep the default demand gate. Add operational gates because payment alone will not distinguish a useful managed process from a cheap software substitute.
A qualified applicant confirms five or more authorisation jobs weekly and a call-led or scattered workflow. Continue towards £199+/month only if one paid pilot also reaches 80% use on eligible jobs, improves median approval time or status-call volume by at least 30%, and produces a specific evidenced route to £199+/month.
09Risks and unknowns
- Prevalence: public disputes show the failure mode, not how many St Helens garages suffer it often enough to pay.
- Incumbent overlap: the current GMS and whether its approval feature is enabled must be checked before accepting a pilot.
- Economics: setup and support time may make a £199 customer unattractive.
- Channel and compliance: SMS, email and WhatsApp have different delivery, consent, security and operating constraints.
- Evidence quality: a timestamp alone does not prove that the correct customer understood and authorised the correct scope.
- The test will settle: whether reachable workshops pay for and consistently use a constrained manual pilot that changes a measured outcome.
- The test will not settle: long-term retention, integration reliability, legal sufficiency, mature data security or whether AI drafting outperforms fixed templates.
