The verdict in three sentences
A custom TMS makes sense when your transport plan, parcel-delivery constraints and client billing logic don't fit a standard tool without expensive workarounds. Budget 60,000-140,000 EUR and 5-9 months for software that optimises routes, ships a driver app with proof of delivery and triggers invoicing automatically. The return shows up in avoided mileage (-18 %), fewer disputes and faster cash, not in saved licences.
Custom vs off-the-shelf: the real trade-off
A market SaaS TMS starts fast and cheap, but charges per user, locks in your business logic and bills every connector. Custom flips the equation: heavier upfront investment, full code ownership, zero per-seat fees.
| Criterion | Standard SaaS TMS | Custom TMS |
|---|---|---|
| Entry cost | 8,000-20,000 EUR setup | 60,000-140,000 EUR |
| Recurring | 25-60 EUR/user/month | Hosting 150-500 EUR/month |
| Time to launch | 4-10 weeks | 5-9 months |
| Route optimisation | Paid optional module | Built to your constraints |
| Driver app + POD | Standard, limited tuning | Custom, offline |
| Client invoicing | Export to rework | Automatic, your rules |
| Code ownership | No | Yes |
For a fleet of 15-40 vehicles, the financial tipping point usually sits around month 24: beyond that, the absence of per-user fees tilts the balance toward custom.
What the TMS must cover in 2026
The gains don't come from the software itself, but from the functions that touch your operating costs directly.
| Function | 2026 operational impact | Estimated gain (order of magnitude) |
|---|---|---|
| Route optimisation | Fewer km, less fuel | -18 % km driven |
| Driver app + photo/signature POD | Instant proof of delivery | -70 % delivery disputes |
| Automatic invoicing | Invoice raised when route closes | -6 days to collection |
| Real-time client tracking | Self-service tracking portal | -30 % calls to support |
| Operations dashboard | Load factor, on-time rate | +8 pts load factor |
| Exception handling | Damaged parcel, absent client | Full traceability |
Mini case study
Thomas runs a regional parcel carrier in Amsterdam: 28 vehicles, 1,100 parcels delivered daily, 4.2 M EUR revenue. His invoicing lags 9 days after delivery and "parcel not received" disputes cost him about 3,500 EUR/month in credit notes.
He invests 95,000 EUR in a custom TMS (delivered in 7 months). First-year results: route optimisation -18 % km, roughly 42,000 EUR saved on fuel and wear; timestamped proof of delivery -70 % disputes, about 29,000 EUR/year; automatic invoicing cutting collection to 3 days (6 days of cash freed). Cumulative first-year savings: ~71,000 EUR, paying back the investment in ~16 months, with no per-user fees afterward.

FAQ
How much does a custom TMS cost in 2026?
Budget 60,000-140,000 EUR depending on scope (optimisation, driver app, invoicing, client portal). Hosting and maintenance then run 150-500 EUR/month, with no per-user cost.
How long does deployment take?
Between 5 and 9 months. A usable first release (order entry + driver app) can ship by month 3, then optimisation and invoicing follow in iterations.
Does the driver app work offline?
Yes. A custom app stores the route locally, captures signatures and photos offline, then syncs when the network returns: essential in dead zones and basements.
Can we keep our accounting software?
Yes. The TMS interfaces with your accounting and payroll tools via API or standard export, avoiding double entry and hardening invoicing.
What happens to the code if we switch vendors?
With custom software, the code and database are yours. You aren't dependent on a vendor that raises prices or shuts down a module.
