How it helps
Less switching.
Fewer handoffs.
- Take secure web payments
Let Square collect guest card details while Trellis keeps the order, amount, location, and payment result connected.
- Collect from the iPhone POS
Use supported Square readers or Tap to Pay on iPhone through the native Trellis payment flow.
- Verify before settlement
Confirm native Square results before Trellis changes the payment ledger or closes the order.
- Bring payout facts into view
Receive signed Square payment and payout updates for reconciliation.
How it fits
One connected
workflow.
Each Trellis location connects to the intended Square seller and Square location.
The guest or staff completes the eligible Square web or native payment flow.
Trellis verifies the result and keeps signed payment and payout facts with the restaurant record.
