POS Integration Troubleshooting

This article covers common problems with your POS integration and how to resolve them, by symptom. You can check each terminal's status on the POS terminals screen in store management.

Transactions Are Not Imported

  • Check the sync status on the POS terminals screen. While it shows Syncing or Queued for sync, wait for it to finish
  • If it shows Sync failed, sync again with Sync with Square or Sync with Smaregi
  • Transactions from before you connected are not imported automatically. Use Sync with Square to import them a period at a time

Scanning the QR Code Says There Is No Receipt Yet

  • The QR code by the register only gives access to the receipt most recently issued at that register, and only for a few minutes after payment
  • Each POS terminal has its own QR code. Check that the customer is scanning the code for the register they paid at
  • If too much time has passed, issue a QR code for that transaction from the store app

Sales or Transaction Counts Don't Match

Transactions cancelled on the POS can remain in your sales and counts. Run Rebuild transaction data on the POS terminals screen to exclude cancelled transactions from sales and counts.

You Can't Add Another POS Terminal

If you see a message that the POS terminal limit has been reached, your plan's terminal limit is full. Upgrade your plan to connect more terminals.

A Customer's Email Receipt Doesn't Arrive

  • Email receipts arrive within a few minutes. If one doesn't, ask the customer to check their spam folder
  • A phone can receive the same receipt only once. If the customer sent it to a wrong address, it can't be sent again — point them to LINE or the app instead
  • Up to 3 receipts can be sent to the same address per hour. After that, the page asks the customer to try again later
