How much does it cost to replace BigChange with your own system?
BigChange charges per VEHICLE — approximately £70/vehicle/month for JobWatch, £100 for JobWatch Plus (figures from Capterra UK and GetApp, July 2025; bigchange.com is quote-only) — so a 15-vehicle firm pays £12,000–£18,000 a year. A notable feature of BigChange contracts is multi-year minimum terms (typically 5 years with 3-year renewal extensions). A custom replacement covering CRM, scheduling, a field mobile app, quoting/invoicing and BI typically costs ~£55,000 to build. The one genuinely complex part is the native GPS telematics — we don't rebuild hardware, we integrate a third-party tracking API or keep your existing trackers. Split across five founding firms, each pays ~£11,000, then a flat ~£3,500 a year, with no multi-year lock-in. Payback typically lands in year 1 or 2.
Side-by-side comparison
| BigChange (per-vehicle) | Your own system | |
|---|---|---|
| Cost model | ~£70–£100 per vehicle/month — scales with the fleet | One-off build share (~£11,000) + flat ~£3,500/yr — no per-vehicle, ever |
| 15-vehicle fleet, year 1 | ~£12,600 (JobWatch) to ~£18,000 (Plus) | ~£14,500 (build share + running) |
| 15-vehicle fleet, year 2 | ~£13,900+ | ~£3,500 |
| 5-year cumulative (15 vehicles) | ~£77,000+ (plus hardware) | ~£28,500 (build share + 5× running) |
| Contract lock-in | ~5-year (60-month) minimum; 3-year renewal extensions; costly to exit | No lock-in — perpetual, escrow-backed licence you own |
| Vehicle tracking | Native telematics tied to the platform and its hardware | Integrated tracking API (or keep existing trackers) — the only non-trivial part, and it stays portable |
| Perpetual access | Stop paying, lose access immediately | Perpetual, escrow-backed licence — your access is contractually protected even if we ever stop trading |
