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.

Match

Each Trellis location connects to the intended Square seller and Square location.

Collect

The guest or staff completes the eligible Square web or native payment flow.

Confirm

Trellis verifies the result and keeps signed payment and payout facts with the restaurant record.
