The verdict in three sentences
Above 40 events a year, a MICE agency pays more in per-attendee licences than it would for a custom tool paid back within two years. The real gain lies less in registration than in per-event margin tracking and automated client reporting, which today eat days of spreadsheet work. A project of 30,000 to 50,000 EUR excl. VAT delivered in 4 to 5 months is the right 2026 order of magnitude for a mid-sized agency in Amsterdam.
Market platforms or custom tool: the maths on 60 events
Event registration platforms charge per attendee or per module. For an agency handling 50 to 2,000 people per event, the bill climbs quickly once congresses pile up.
| Item (2026 order of magnitude) | Market SaaS platform | Custom tool |
|---|---|---|
| Cost per attendee | 2 to 5 EUR | 0 EUR |
| Annual volume (60 events, 12,000 attendees) | 24,000 to 60,000 EUR per year | 0 EUR |
| Initial development | 0 EUR | 30,000 to 50,000 EUR excl. VAT |
| Hosting and maintenance | included | 4,000 to 7,000 EUR per year |
| White label in client branding | option, 1,500 to 3,000 EUR per year | included |
| Per-event margin tracking | missing or manual export | native |
| Cumulative 3-year cost | 72,000 to 180,000 EUR | 42,000 to 71,000 EUR excl. VAT |
Break-even sits around 8,000 attendees a year. Below that, a platform remains reasonable; above it, every extra congress widens the gap.
The modules that save time and protect margin
A MICE agency does not sell registrations, it sells a full service with accommodation, transport, catering and content. The software must therefore connect the attendee front end to the budget back office.
| Module | Concrete function | Measurable gain |
|---|---|---|
| Dynamic registration forms | questions by category (speaker, VIP, exhibitor), rates and quotas | 60% fewer reminders |
| QR badges and check-in | on-site printing, smartphone scan at each room entrance | reception queue cut by 3 |
| Accommodation management | room blocks, allocations, release alerts | 1 to 2% hotel penalties avoided |
| Per-event budget and margin | quote, supplier commitments, actuals, live variance | margin tracked instead of discovered |
| Automated client reporting | attendance, satisfaction, cost per attendee | 3 days saved per event |
| Client portal | the buyer follows registrations and invoices | 30% fewer emails |
| GDPR compliance | consents, automatic data purge after 24 months | Dutch DPA risk under control |
Automated reporting is often the module that wins management over: across 60 events, 3 days saved means 180 person-days a year, more than one full-time employee.
Timeline, phases and budget per step
| Phase | Duration | Indicative budget excl. VAT |
|---|---|---|
| Scoping and workshops with project managers | 3 weeks | 3,000 to 5,000 EUR |
| Registration, badges, QR check-in | 6 weeks | 10,000 to 16,000 EUR |
| Budget, suppliers and margin | 5 weeks | 8,000 to 14,000 EUR |
| Reporting and client portal | 4 weeks | 6,000 to 10,000 EUR |
| Acceptance on a pilot event | 2 weeks | 3,000 to 5,000 EUR |
A pilot on a 150-person seminar before congress season lets you fix friction points with no commercial risk.

Sanne, managing director of a MICE agency in Amsterdam, runs 60 events and about 12,000 attendees a year. Her current platform costs 3.50 EUR per attendee, or 42,000 EUR a year. Her project managers spend 3 days per event consolidating budgets and wrap-up reports, 180 days valued at 350 EUR: 63,000 EUR. A custom tool at 42,000 EUR excl. VAT plus 5,500 EUR annual maintenance replaces the licence and cuts reporting time by four. First-year saving: 42,000 + 47,000 - 47,500 = 41,500 EUR, then close to 84,000 EUR a year afterwards.
FAQ
How much does custom event software cost for a MICE agency?
Budget 30,000 to 50,000 EUR excl. VAT for an agency running 40 to 80 events a year, with registration, QR badges, budgets and reporting. Maintenance then runs 4,000 to 7,000 EUR a year.
How long until the tool is live?
The standard timeline is 4 to 5 months including acceptance. We recommend shipping the registration module first, from week eight, to use it on a pilot event.
Can we import our event history?
Yes, attendee and budget files exported as CSV or Excel are imported during migration. Allow 1 to 2 weeks for 3 years of history.
Does QR check-in work offline?
The scanning app keeps the list locally and syncs as soon as the network returns. It handles more than 2,000 attendees per event and 10 simultaneous checkpoints.
Is online payment for registrations included?
Stripe or Adyen integration is planned, with automatic invoicing. Transaction fees stay around 1.5% + 0.25 EUR per European payment.
