Two workflows depending on how you took the initial sale:
- Auth-only then capture-with-tip (recommended for restaurants):
- On the A80, use the Restaurant / Tab app instead of Sale
- Card is pre-authorized for the check amount + configurable buffer (usually 20%)
- After the customer signs and adds tip, staff enters the tip and taps Adjust & Close
- Capture happens automatically at batch close
- Sale then tip-adjust in portal (if you already took a Sale):
- Portal → Transactions → find the sale → Adjust
- Add the tip amount (must be within 20% of the original), save
- Must be done before the batch closes that night
Workflow 1 is the correct restaurant setup — the terminal app defaults matter. If your A80 doesn't have the Restaurant profile enabled, your ISO can push it remotely.
