The verdict in three sentences
For an Amsterdam MICE agency running 120 events a year, the real cost is not the licence but the hours lost copying registrations, rooms and invoices between six tools. An off-the-shelf platform (EUR 5,000 to 25,000 a year) is enough while your processes stay standard, but it tracks neither margin per event nor accounting. Beyond 80 events a year, custom software at EUR 40,000 to 80,000 excl. VAT delivered in 4 months often pays for itself in under two years.
Six tools, one agency: where the money goes
The typical setup of a seminar and congress agency in 2026: an online registration tool, an Excel file for attendee accommodation, badge software, a budget spreadsheet, the accounting tool and email for everything else. Each 150-attendee event generates on average 300 to 500 changes (room swaps, dietary needs, transfers, cancellations). Each change keyed in two or three times is where rooming list errors and billing gaps come from.
| Item | Current setup (6 tools) | With unified software | Estimated gap |
|---|---|---|---|
| Preparation time per event | 35 to 45 h | 20 to 25 h | -40% |
| Re-entries per 150-attendee event | 300 to 500 | under 50 | -85% |
| Budget close time | 3 to 6 weeks | 3 to 5 days | -80% |
| Rooming list errors reported | 4 to 8 per event | 0 to 1 | -85% |
| Margin visibility | after the event | real time | decisive |
| Combined subscriptions | EUR 9,000 to 14,000 a year | built in | to compare |
These 2026 orders of magnitude come from agencies of 8 to 25 people. The main issue remains margin: on a EUR 120,000 seminar, an undetected 3-point slip means EUR 3,600 lost.
Off-the-shelf or custom: 2026 prices
| Option | Upfront cost | Annual cost | Time to go live | Limits |
|---|---|---|---|---|
| Simple registration platform | EUR 0 to 2,000 | EUR 5,000 to 9,000 | 2 to 4 weeks | no accommodation, no budget |
| Full event suite | EUR 3,000 to 10,000 | EUR 15,000 to 25,000 | 2 to 3 months | limited margin and accounting, per-attendee fees |
| Custom core (registration, accommodation, QR badges) | EUR 40,000 to 55,000 excl. VAT | EUR 4,000 to 7,000 (hosting, maintenance) | 3 to 4 months | you set priorities |
| Full custom (+ budget, margin, accounting) | EUR 60,000 to 80,000 excl. VAT | EUR 6,000 to 10,000 | 4 months | upfront investment |
| Accounting connector only (add-on) | EUR 6,000 to 12,000 excl. VAT | included | 3 to 5 weeks | depends on accounting tool |
Custom software covers the full journey: a client-branded registration form, hotel allotment and rooming list management, QR badges scanned at check-in, forecast budget per event compared with actuals, and automatic export of supplier and client invoices to your accounting software (Exact Online, Twinfield or Xero). You own the code and pay no per-attendee fees, which matters when some congresses exceed 1,000 registrants.
The scope that makes the project pay
| Module | Priority | Share of budget | Main gain |
|---|---|---|---|
| Online registration and payment | high | 20% | no more Excel files sent by email |
| Accommodation and rooming list | high | 20% | zero hotel errors |
| QR badges and access control | medium | 10% | check-in 3 times faster |
| Budget per event and margin | high | 25% | margin tracked in real time |
| Accounting connection | high | 15% | close in a few days |
| Client portal (quotes, tracking) | optional | 10% | fewer calls and emails |
Splitting into two phases is usually sensible: phase 1 (registration, accommodation, badges) live after 10 weeks, phase 2 (budget, margin, accounting) delivered in month four.

Sanne, managing director of a 14-person MICE agency in Amsterdam Zuid, runs 120 events a year. Her project managers spend 15 fewer hours per event after rollout, i.e. 1,800 hours a year. At a loaded cost of EUR 45 an hour, that is EUR 81,000 of time recovered. She also cuts EUR 11,000 of annual subscriptions. For a full project at EUR 70,000 excl. VAT plus EUR 8,000 annual maintenance, payback comes in under 10 months, before counting the margin protected on large congresses.
