Go to the store admin interface and search for the relevant order. You will find a BuyProof data action for each order.

All ordered items will be listed here. And for each item in your order, you can add: serial number, warranty and status, whether the item will be subject to proof of issue

BuyProof data action with filled-in item fields

Click \ after editing all items in this order. The data will be saved and can be edited before the order is fulfilled. Only when the order is fulfilled will the actual issuance of the proof begin. {% hint style="warning" %} Be careful and double-check the details before fulfilling the order. The data cannot be changed later. {% endhint %} {% hint style="info" %} Note: in some cases, you may want to issue proof manually. Please read the [separate guide](/buyproof/merchant-guide/manual-proof-issuing.md). {% endhint %}
