Answer
What POS system should a boutique hotel with a restaurant use?
For boutique hotels with F&B operations, the POS shortlist is Toast (US default, restaurant-specialist), Lightspeed (international multi-outlet), and Square POS (B&Bs and smallest properties). Cloud-native POS with PMS integration via partner APIs is standard in 2026.
The shortlist
Toast is the most-deployed cloud POS in US hospitality F&B. Lightspeed covers international independents with multi-outlet operations (restaurant + bar + spa + retail). Square POS wins for B&Bs and the smallest hotels wanting free POS software with pay-per-transaction.
PMS integration
Modern POSes integrate with PMS via partner APIs for room-charge billing (charge F&B to the guest folio). Toast, Lightspeed and Square all have partner integrations with major cloud PMSes (Cloudbeds, Mews, Apaleo). For deep enterprise hospitality POS, Oracle MICROS pairs natively with Opera PMS.
