Fulfill an order (and notify the customer)
Click the order, set Status to fulfilled, add the Carrier and Tracking #, then Mark fulfilled + save. The customer is automatically emailed the tracking. Use Save (not fulfill) if you only want to change notes without emailing.
Buy a USPS label (Stamps.com)
On a paid order, the USPS label panel quotes real rates (weight prefills from the catalog; adjust it to the packed box), and Buy label purchases the postage on the company Stamps.com account, marks the order fulfilled, and emails the customer the tracking, all in one click. A misprint? Void label refunds the postage and puts the order back to paid. The panel appears once Stamps.com is connected in Settings. Print label ↗ opens a print view that fetches the label fresh and prints it at actual size on plain letter paper; keep the print dialog at 100% scale and cut along the label edge.
Refund a customer
Open the order, go to Refund, enter an amount (defaults to the full remaining balance), and click Refund. The money goes back through the original card/PayPal. A full refund also marks the order refunded. Manual/phone orders have no card on file, so refund those in Square/PayPal directly.
Fix an order
Edit items & address lets you correct line items or the shipping address; the total recalculates. This does not change the payment already taken — use Refund for money back.
Resend an email
Resend receipt re-sends the order confirmation; Resend shipping email re-sends the tracking notice. Handy when a customer says they never got it.
Take a phone order
New order records an order taken over the phone: enter the customer, ship-to, and line items. No email is sent to the customer.
Work in bulk & export
Tick several orders to set their status at once (no emails sent). Export CSV downloads the full filtered set — combine it with the status filter and date range for bookkeeping.
Most actions ask you to confirm before anything permanent happens, and you'll see a small confirmation once it's done.
