Design checkout, payment and shipping
Payment methods, shipping rates, stock locations and document numbering: the rules a buyer meets at checkout.
Everything here is decided once and then answers thousands of checkouts without anyone touching it. That is also why it deserves care: a shipping matrix with no pallet band, or a number range your ERP cannot parse, is discovered by a customer rather than by you.
Work through the articles in order. Payment and shipping decide what a buyer can choose; stock decides what you can promise; number ranges decide whether the documents are accepted at the other end.
- Checkout configuration — the four sets of rules that meet at the end of a cart.
- Payment methods — invoice, prepayment, card, and the fees and limits on each.
- Shipping methods and carriers — rate matrices, carriers, cut-off times and the delivery promise.
- Stock, locations and availability — what "in stock" means, and what happens when it is not.
- Number ranges — order, delivery-note and return numbering.
