What is order-to-cash (O2C)?

Order-to-cash covers the full revenue cycle: receiving the order, fulfilling it, issuing an invoice, managing AR, collecting payment, and posting the cash. Each step can introduce a delay or a leak. An order that takes two weeks to fulfill delays the invoice by two weeks. An invoice missing a required PO number sits in the customer's AP queue. A payment that clears but is applied to the wrong invoice generates unnecessary collection activity.

For most small service businesses, the order-to-cash cycle is not managed as an integrated process — it is a series of separate tasks spread across invoicing software, a phone, and QuickBooks. Tightening each handoff — faster invoicing, clearer payment terms, earlier first follow-up — shortens DSO without changing anything about the product or pricing.
