The verdict in three sentences
A transport management system (TMS) that optimizes routes and connects EDI to your ERP attacks your two biggest cost lines directly: fuel and planning time. In 2026 in Amsterdam, the choice is between an off-the-shelf TMS at EUR 40-120 per user/month and a custom build at EUR 60,000-150,000 delivered in 5 to 10 months. TCO and integration quality decide the debate, not the license price.
What a TMS covers in 2026
A logistics director expects a TMS to manage transport orders, optimize routes, exchange EDI with shippers and carriers, track deliveries and surface KPIs. Here is the off-the-shelf vs custom comparison.
| Criterion | Off-the-shelf TMS | Custom |
|---|---|---|
| Entry cost | EUR 40-120/user/month | EUR 60,000-150,000 |
| Deployment time | 1-4 months | 5-10 months |
| Route optimization | Standard, configurable | On your exact constraints |
| Shipper EDI | Existing connectors | Custom, all formats |
| ERP integration | Connector-dependent | Native and complete |
| Extensibility | Vendor roadmap | Your roadmap |
| Code ownership | No | Yes |
Where a TMS makes money
TMS gains are measurable: fewer empty miles, better load factor, faster planning and reliable invoicing. 2026 order of magnitude for a mid-size fleet.
| Lever | Estimated gain | Calculation base |
|---|---|---|
| Route optimization | -5 to 12% miles | Fuel + wear |
| Load factor | +3 to 8 pts | Margin per route |
| Planning time | -30 to 50% | Planner cost |
| Delivery disputes | -20 to 40% | Credits and penalties |
| Automated invoicing | -10 to 20 days DSO | Cash flow |

Sarah is COO of a transport firm in Amsterdam: 28 vehicles, EUR 3.1M operating cost, of which EUR 780,000 in fuel. A custom build at EUR 110,000, delivered in 8 months, optimizes routes and cuts empty miles by 8%. Fuel saving: ~EUR 62,000/year. Adding recovered planning time (2 planners, -40%) and disputes avoided, the tool pays for itself in under 18 months and becomes a company asset, with no per-seat subscription.
FAQ
Off-the-shelf or custom TMS? As a 2026 rule, off-the-shelf fits under 20-25 users with standard flows. Custom pays off when EDI, route optimization or ERP integration fall outside available connectors.
Is EDI essential? To work with large shippers, yes: transport orders, acknowledgments and invoices exchange over EDI. A TMS must handle your formats (EDIFACT, XML, API) without re-keying.
What fuel saving is realistic? As an order of magnitude, 5 to 12% of miles saved through route optimization, often the first source of return on investment.
How long to deploy? 1 to 4 months for an off-the-shelf TMS, 5 to 10 months for custom including EDI, optimization and ERP integration.
How do I integrate the TMS with my ERP? Via API or EDI depending on your ERP. In custom, integration is native and avoids double entry across transport, invoicing and accounting.
