If you run a 5–20 vehicle taxi or private hire fleet, the software market in 2026 is either brilliantly cheap or ruinously expensive — and there is almost no middle ground unless you know exactly what to buy. This blueprint is the checklist we use with UK operators every week: what to demand, what to ignore, what it should cost, and how to be live in a fortnight without losing a single booking.
Why Small Fleets Get Sold the Wrong Stack
The vendor market is polarised. On one side, enterprise platforms (Autocab, iCabbi) price against 80+ vehicle operators — great software, wrong invoice. On the other, ride-hail marketplaces (Uber Fleet, Bolt Partner) look free until you notice the 15–25% commission. Small fleets fall between the cracks and end up either overpaying by 3× or renting their own customer base back from an aggregator. Neither is necessary.

The 12 Questions Every Vendor Must Answer Before You Sign
- Do the passenger and driver apps ship under my Apple and Google developer accounts?
- Is there any per-trip commission, ever?
- What is the total 3-year cost for a 10-vehicle fleet, itemised?
- Does the price include SMS, or is it billed per message?
- Are corporate accounts and PDF invoicing in the base price?
- How long does data migration from my current dispatcher take?
- What happens to my customer data and app store listings if I leave?
- Is there an API I can query without an "enterprise upgrade"?
- Do you support multi-zone tariffs, waiting time and airport fixed pricing out of the box?
- What is the auto-dispatch fallback when GPS signal drops?
- Can I run the passenger web booking on my own domain?
- Which UK compliance regimes do you support natively — TfL, Wolverhampton, Leeds, Manchester, Glasgow?
The 14-Day Migration Timeline
Days 1–2 · Kick-off. Brand assets, tariff table, driver list, corporate account export, developer account handover.
Days 3–5 · Configuration. Fare rules, zones, airport pricing, drivers loaded, apps submitted to stores in review.
Days 6–8 · Parallel run. New system live for one shift alongside the old dispatcher; discrepancies logged and fixed.
Days 9–11 · Driver training. Hands-on with the driver app; short refresher videos for the two most confusing edges (offline mode, in-app cash).
Days 12–14 · Cutover. Old system read-only. Corporate clients informed. Booking widget replaced. Success = zero missed bookings on cutover day.
Red Flags in a Vendor Demo
- They demo their app on their App Store listing, not a client's white-label one.
- Pricing is "call us" — every SaaS-priced fleet ends up paying more than the published tier.
- Corporate billing is a "coming soon" module.
- Auto-dispatch is really just a broadcast to all drivers ("first to accept").
- Data migration is billed hourly with no cap.
Bottom Line for a 5–20 Vehicle Fleet
If you are being quoted £1,500/month, walk away — you are paying enterprise for a small-fleet problem. If you are being asked to accept 10%+ commission, walk faster — that is your growth budget for the next three years. The right stack for a 10-vehicle fleet in 2026 costs about the same as one used vehicle, ships in two weeks, and gives you branded apps that outlive your current dispatcher by a decade.
