The verdict in three sentences
Above 25,000 to 30,000 visitors a year, the per-ticket fee of a SaaS ticketing tool becomes a trade show organiser's largest digital cost. A custom platform with registration, QR badges, an exhibitor scanning app and lead export costs 50,000 to 120,000 EUR excluding VAT in 2026 and pays back in 2 to 3 editions. The real gain lies in visitor data and lead scanning resold to exhibitors, which you do not control on a third-party tool.
What you pay today
B2B event ticketing tools charge per transaction, often with paid add-ons for badges, scanning and export. For an Amsterdam organiser with 6 shows and 40,000 visitors, the bill looks like this (2026 orders of magnitude).
| Item | SaaS event platform | Custom platform |
|---|---|---|
| Fee per ticket or badge | 1 to 3 EUR | 0 EUR |
| Annual cost for 40,000 visitors | 40,000 to 120,000 EUR | 0 EUR in fees |
| Exhibitor scanning module | 150 to 400 EUR per exhibitor per show | included, resellable to exhibitors |
| On-site badge printing | 0.30 to 0.80 EUR per badge | 0.30 to 0.80 EUR per badge |
| Hosting and maintenance | included | 8,000 to 18,000 EUR per year |
| Ownership of visitor data | shared or limited | full, GDPR compliant |
| Journey customisation | limited to options | complete |
The most underestimated gap is lead scanning: with 600 exhibitors a year and a 200 EUR module, that is 120,000 EUR the organiser can invoice directly instead of leaving it to the provider.
Scope and budget of a custom platform
| Module | Function | Estimated budget excl. VAT |
|---|---|---|
| Registration and ticketing | Forms per profile, exhibitor invite codes, card, iDEAL and bank transfer | 12,000 - 25,000 EUR |
| QR badges | PDF and wallet generation, print on demand on site | 6,000 - 15,000 EUR |
| Access control | Entrance scanning, hall capacity, offline mode | 8,000 - 18,000 EUR |
| Exhibitor scanning app | PWA, lead qualification, notes, CSV and CRM export | 10,000 - 25,000 EUR |
| Organiser back office | Dashboards, reminders, statistics per show | 8,000 - 20,000 EUR |
| Integrations | CRM, email tool, accounting | 6,000 - 17,000 EUR |
| Total | Full project | 50,000 - 120,000 EUR |
The realistic timeline is 4 to 6 months. Start at least 3 months before registration opens for the first target show, and plan a full-scale test on the smallest event of the year.
Technical points not to overlook
On opening day, access control must absorb peaks of 2,000 to 3,000 entries per hour. Scanners must work offline and resync, because Wi-Fi in an exhibition hall saturates quickly. Under GDPR, consent to share contact details with the exhibitor must be explicit at the time of scanning, with a retention period defined in your records.
Mini case study
Daan, managing director of a trade show organiser in Amsterdam (illustrative persona), pays 2 EUR per visitor on 40,000 visitors, so 80,000 EUR a year, plus 60,000 EUR in scanning modules for 300 exhibitors. He invests 95,000 EUR excluding VAT in a custom platform and 14,000 EUR a year in maintenance. He resells scanning at 150 EUR per exhibitor, generating 45,000 EUR. Annual gain: 80,000 + 60,000 + 45,000 - 14,000 = 171,000 EUR. With 6 shows a year, the investment is covered by the third edition of the year, about 7 months.

FAQ
At what volume does custom become profitable?
Usually above 25,000 to 30,000 visitors a year, when fees exceed 40,000 EUR. Below that, a SaaS tool is often cheaper.
How long does development take?
Allow 4 to 6 months, including 3 to 4 weeks of real-world testing. Target a modest first show of around 3,000 to 5,000 visitors.
Can QR badges be printed on site?
Yes, with thermal badge printers connected to the back office, at 0.30 to 0.80 EUR per badge. One kiosk serves 150 to 250 visitors per hour.
Can we charge exhibitors for lead scanning?
Yes, it is a common revenue stream, between 100 and 300 EUR per exhibitor per show. The export must be compatible with major CRMs.
How do we handle GDPR during scanning?
The visitor consents to sharing contact details at registration and at the time of scanning. The platform must log that consent and delete data at the end of the set period, often 3 years.
