The verdict in three sentences
A custom room and resource booking app costs, as a 2026 order of magnitude, USD 13,000 to 33,000 (120,000 to 300,000 MAD for our North African clients) for a 600-employee headquarters, delivered in about 10 weeks. Synced with Microsoft 365, linked to access badges and door displays, it eliminates booked-but-empty rooms and typically lifts real occupancy from 41% to 68%. Against SaaS tools billed per room, a custom build pays off from year two when it also handles vehicles and equipment.
The problem: 35 rooms, 20 vehicles and an inbox
The headquarters of a services group in Singapore's CBD manages its 35 meeting rooms through Outlook calendars and its 20 pool vehicles by email with facilities. Rooms are often booked just in case and then left empty, while teams rent external rooms because nothing looks available. Vehicles go to whoever emails first.
| Indicator before the project | Measured value | Consequence |
|---|---|---|
| Real room occupancy | 41% | Rooms blocked but empty |
| Bookings with no-show | 28% | About 120 slots lost per week |
| External room rental | USD 2,000 to 2,700 per month | Off-sites and committees moved out |
| Facilities time spent on vehicles | 25 hours per month | Emails and calls |
| Vehicle utilisation | 52% | Oversized fleet |
| Vehicle condition disputes | 4 to 6 per month | No logged inspection |
What the app does and what it costs
The app provides a single view of rooms, vehicles and equipment (projectors, video-conferencing kits). Room bookings sync both ways with Outlook and Teams. A display at each room entrance shows the schedule and asks for check-in: without confirmation within 10 minutes, the room is released. For vehicles, the employee books, the manager approves, and a photo inspection is logged at pick-up and return.
| Tier | 2026 budget | Timeline | Features |
|---|---|---|---|
| Rooms only | USD 13,000 to 18,500 | 8 weeks | Booking, Microsoft 365 sync, auto-release |
| Rooms and vehicles | USD 18,500 to 26,000 | 10 weeks | + fleet, manager approval, photo inspection |
| Full with badges and displays | USD 26,000 to 33,000 | 12 weeks | + access badges, door displays, occupancy analytics |
| Door displays (rugged tablets) | USD 270 to 490 per room | One-off | Hardware and wall mount |
| Local or cloud hosting | USD 160 to 430 per month | Ongoing | Compliance with local data protection law (PDPA in Singapore) |
| Maintenance | USD 2,700 to 4,900 per year | Ongoing | Fixes, improvements, support |
Custom build or per-room SaaS?
International workplace SaaS tools usually charge USD 30 to 60 per room per month, plus paid modules for displays and sensors. They rarely handle pool vehicles.
| Criterion | Per-room SaaS | Custom app |
|---|---|---|
| Annual cost for 35 rooms | USD 12,600 to 25,200 | USD 4,600 to 10,100 (hosting and maintenance) |
| 3-year cost | USD 37,800 to 75,600 | USD 36,000 to 52,000 (project included) |
| Vehicle management | Rarely, separate module | Included |
| Billing | Per seat or room, card payment | On invoice |
| Data | Often hosted abroad | Hosting under your control |
| Fit with internal rules | Limited configuration | Complete |
Mini case study
Karim, facilities director of a 600-employee headquarters, chooses the Rooms and vehicles tier at USD 23,000 plus 35 displays at USD 380, i.e. USD 36,300 in total. Six months after launch, occupancy reaches 68%: external room rentals at USD 2,200 per month disappear, and the fleet is cut by 3 leased vehicles at USD 600 per month each. Savings reach USD 4,000 per month, or USD 48,000 per year. After USD 6,500 of annual running costs, the net gain is USD 41,500: the project pays back in under 11 months.

FAQ
How much does a room booking app cost in 2026?
As an order of magnitude, USD 13,000 to 33,000 depending on scope, excluding door displays. A rooms-and-vehicles version lands around USD 23,000.
Is the Outlook and Teams sync reliable?
Yes, it runs on the Microsoft Graph API and works both ways. A booking made in Outlook appears in the app in under 30 seconds.
How do we stop rooms being booked but left empty?
The door display asks for check-in within 10 minutes. This feature alone cuts no-shows from 28% to under 8% on average.
Where should the data be hosted?
In Singapore, the PDPA governs personal data and its transfer abroad (in Morocco, law 09-08 and the CNDP play that role). Local hosting from about USD 160 per month simplifies compliance.
Can we start with rooms and add vehicles later?
Yes, the architecture is modular. Adding the fleet later costs about USD 6,500 to 8,700.
