What is fulfillment?

The customer experiences your shop for four minutes and your fulfillment for four days, which is a useful way of understanding where online retail is actually won. Fulfillment covers everything that happens after the payment confirmation: inventory held somewhere, the order picked from a shelf, packed, an invoice issued and transmitted, a courier label generated, the consignment handed over and tracked, and — for a meaningful share of orders — the whole sequence run in reverse when the customer returns it. Each of those steps is either a system talking to another system or a person retyping something, and which of the two determines your cost per order at volume. It is worth being blunt about the arithmetic, because it surprises people. Returns in some categories exceed a quarter of orders, courier claims and repeat deliveries erode margin quietly, and warehouse labour costs rise fastest exactly when growth arrives. Companies that treat fulfillment as an afterthought discover their growth ceiling is operational rather than commercial: more marketing produces more orders, more orders produce more errors, and the errors consume the margin the marketing was supposed to create.
