The verdict in three sentences
A custom B2B booking platform costs between USD 13,500 and 33,500 (EUR 12,200 to 30,500) in 2026, depending on the number of bookable resources and integrations. For an operator of meeting rooms and shuttles, it removes the 10 to 15% commission taken by third-party platforms and automates quotes and monthly invoicing. With a 10 to 14 week timeline, the investment usually pays back in 14 to 24 months once around USD 117,000 of revenue is booked online.
What a B2B booking platform must do
A corporate client does not book like a consumer. The executive assistant at a bank or an international organisation wants to see free slots, block a 40-seat room with projector and coffee break, add an airport shuttle, get a PDF quote for internal approval, and be invoiced at month end on a corporate account. The platform must therefore handle several user levels (requester, approver, accounts), negotiated rates per client and an approval workflow.
| Module | Function | Indicative 2026 budget (USD, excl. tax) |
|---|---|---|
| Availability calendar | Rooms, vehicles, drivers, holds and options | 3,000 to 5,900 |
| Automatic quotes | Client rates, options, discounts, signed PDF | 2,000 to 4,200 |
| Corporate accounts | Multi-user, roles, approval workflow | 2,500 to 5,000 |
| Monthly invoicing | Consolidated statement, accounting export, reminders | 1,700 to 4,200 |
| Online payment | Cards and wallets via Stripe, local methods | 1,350 to 3,000 |
| Back office and analytics | Occupancy rate, revenue per client, driver schedule | 2,000 to 5,000 |
| Notifications | Email, SMS, WhatsApp confirmations and reminders | 850 to 2,000 |
A base version covering the first four modules sits around USD 13,500. The full version, with a driver app, accounting software integration and an executive dashboard, lands between USD 25,000 and 33,500.
Third-party platform or custom build: the real math
Event marketplaces and transport aggregators take a commission on every booking. They bring visibility, but recurring corporate clients end up booking through them out of habit, and the margin goes to commission.
| Criterion | Third-party platform | Custom platform |
|---|---|---|
| Entry cost | USD 0 to 850 | USD 13,500 to 33,500 |
| Commission per booking | 10 to 15% | 0% (payment fees 1 to 2%) |
| Negotiated rates per client | Rarely possible | Native |
| Monthly B2B invoicing | No | Yes, consolidated statement |
| Ownership of client data | Shared with the platform | Full, compliant with local data law |
| Annual maintenance | Included | 10 to 15% of initial budget |
| Time to launch | 1 to 2 weeks | 10 to 14 weeks |
The tipping point is usually around USD 85,000 to 100,000 of annual bookings flowing through the third-party platform. Below that, the marketplace remains worth it for awareness. Above it, custom becomes an asset.
Typical 12-week project timeline
Weeks 1 and 2 are for scoping: resource inventory, rate cards, cancellation rules and client approval workflows. Weeks 3 to 9 cover development in two-week iterations, with a demo at the end of each sprint. Weeks 10 to 12 are dedicated to migrating existing clients, testing with three or four pilot accounts and training the sales team. Also budget hosting: USD 65 to 200 per month depending on traffic.

Omar runs a meeting room and shuttle company in Dubai Business Bay with USD 200,000 annual revenue, 60% of it through two third-party platforms at an average 12% commission. He pays 0.6 x 200,000 x 0.12 = USD 14,400 in commissions per year. A custom platform at USD 23,500, plus USD 3,000 annual maintenance, costs him USD 26,500 in year one. By moving 70% of that flow to his own tool, he saves about USD 10,000 in commissions in year one, and the savings exceed maintenance from year two. Estimated payback: 22 months, not counting 3 days a month saved on manual invoicing.
