Square Terminal consignment checkout

Before you start

Connect Square first and approve the Terminal permissions. The Square account needs payment write, in-person payment, and device credential management access so SECND can create pairing codes and send checkouts to your Terminal.

Pair a Terminal

Ring up a customer

In Consignment → Sell, scan or tap items to build the cart. Click Pay, choose Card as the payment method, and click Send to Square Terminal. The customer taps, inserts, or swipes on the Terminal. Once Square marks the checkout complete, SECND records one sale row per cart item under the same transaction.

Cash checkouts skip Square Terminal and record directly. For Canadian cash sales, SECND rounds the transaction total to the nearest nickel and stores the rounding adjustment on the sale.

Payment states

Pending means the Terminal is waiting for the customer. In progress means Square is processing. Completedrecords the sale with Square's payment id. Cancelled and Timed out stop the checkout so staff can retry or choose another payment method.
