Can guests keep ordering rounds by QR and pay once at the end of the meal?

Yes, if your QR system supports it. Petpooja, sunday's Hybrid mode and Toast tabs let guests order extra rounds and pay once at the end. Check that rounds join one bill.

• Petpooja Scan & Order: guests at one table can order separately and add rounds at any time. Every order joins the same table bill.
• sunday Hybrid: guests order extra items through the meal and pay once at the end. It is made to support table service, not replace it.
• Toast tabs: standard tabs take no card up front. Pre-auth tabs collect a card before items go to the kitchen.
• Ask the vendor: do extra rounds join one bill, or create separate orders?
