Plain definition
Order to cash is the connected process that begins when a customer order is accepted and ends when the business has delivered, invoiced, collected, recorded, and reviewed the cash. It commonly includes customer setup, credit approval, pricing, order entry, fulfilment, delivery evidence, billing, collections, cash application, and dispute handling.
Its purpose is not merely to issue invoices quickly. The process should make sure the business accepts orders it can fulfil on agreed terms, bills what it delivered, collects cash accurately, and learns from credit, pricing, or service problems. Different people and systems may perform the steps, but the handoffs and evidence must join up.
Illustrative example
Suppose a sales representative accepts a large order from a new customer near quarter-end. Before fulfilment, credit control checks the approved credit limit and payment history; operations confirms available stock and the promised delivery date; and finance verifies the price against the authorised quotation. The warehouse records delivery, billing issues the invoice from that evidence, and collections follows up when payment becomes overdue.
A dispute later reveals that the customer expected an installation service not listed in the order. The process owner traces the quotation, order, delivery, and invoice to decide whether to correct the bill, seek payment, or change the sales-order checklist. The company avoids treating an overdue receivable as a collections failure when its cause was an unclear commercial commitment.
Order to cash is a process, not a single department. Sales, operations, credit, billing, and finance may each hold different responsibilities and controls.
Why it matters
It connects revenue ambition to delivery, customer terms, cash collection, and reliable accounting evidence.
It prevents teams from celebrating an order or invoice while ignoring whether the business can deliver, collect, or defend the amount billed.
Practical consequence
Map the handoffs from approved quotation to cash application, naming the evidence, system record, accountable role, and exception route at each point.
Review disputes, credit notes, overdue receivables, and manual price changes by cause, then change the upstream step that repeatedly creates the problem.
