Questions and answers

What about extra costs? Add the work as an offer. Offers are not counted until the customer agrees; declined ones are never billed.
What counts against the free allowance? Only final payments: orders paid in full at pickup. The allowance of 30 final payments resets every 30 days. New orders and deposits are never blocked.
Do I need a special printer? No. Labels and receipts print on a 58 or 80 mm receipt printer connected to the phone. Without a printer, receipts go out over WhatsApp.
