Order-to-Cash (O2C) Jobs Explained: Billing, Cash Application, Collections and Disputes

The short version

Order-to-cash, written O2C or OTC, covers everything from a customer placing an order to the company receiving and recording the money. If P2P is how a company spends, O2C is how it earns. Companies care deeply about it because late or missing payments hurt cash flow.

The O2C cycle, step by step

1. Order management: the customer order is received, checked and entered, with prices and terms.
2. Credit management: the company checks whether the customer can be trusted with credit and sets a limit.
3. Fulfilment and delivery: goods are shipped or services delivered.
4. Billing: an invoice is created and sent to the customer with the correct amounts and taxes.
5. Collections: the team reminds customers about due invoices and follows up on overdue ones.
6. Cash application: payments received are matched to the right invoices.
7. Dispute and deduction management: reasons for short or delayed payments are investigated and resolved.
8. Reporting: ageing, collections and key measures are shared with management.
