Designing a Room-Charge POS

Room charge sounds like a trivial feature. In practice, it's the integration most hotel F&B operations get wrong — usually because the POS lives in a separate vendor, and the bridge is built on overnight CSV imports.

The three failure modes

1. Late posting: guest checks out before the F&B charge syncs. Walked.
2. Wrong folio: room-shared bookings, group masters, split folios — the POS doesn't know.
3. Tax mismatch: F&B has a different tax slab from room, but the POS posts a single line with the wrong category.

Why same-database matters

In StaySynq, the POS and the PMS share a single transactional database. When a waiter taps 'charge to room', the folio gets the line in the same database transaction — atomic, audit-logged, no sync delay.

“If your POS and PMS are two systems with a bridge, you have two systems. If they share a database, you have one.

It also unlocks workflows that third-party POSes can't do at all: meal plan vouchers tied to a specific stay, automatic comping on VIP folios, real-time food-cost-as-percent-of-occupancy dashboards.
