What is Invoice sales? Complete Guide to Lending and Debtor Management
Invoice sales is an accounting method where revenue is recorded at the time an invoice is issued to the customer, regardless of when payment is actually received. This is a fundamental part of the periodization principle in the accounts and directly affects the company’s operating result and liquidity management .
For a thorough introduction to sales in accounting, see the article [Sales](/regnskap/begreper/salg/ “Salg " Oversikt over salgskonsepter i Norsk Regnskap”).
Section 1: Basics of Invoice sales
Invoice sales differ from cash sales in that there is a time interval between delivery and payment. This creates both opportunities and challenges for the company, as it affects working capital and requires active debtor follow-up .
Characteristics of Invoice sales
- Credit period: The customer is given a payment deadline, usually 14-30 days
- Risk: The company bears the risk that the customer does not pay
- Cash flow: Negative impact on short-term liquidity
- Customer service: Increased customer satisfaction through flexible payment terms
Section 2: Accounting of invoice sales
When a company sells on invoice, the transaction must be booked correctly according to double entry and Norwegian accounting rules.
Bookkeeping example
When selling goods for NOK 10,000 + NOK 2,500 VAT on the invoice:
| Account | Account Name | Debit | Credit |
|---|---|---|---|
| 1500 | Accounts receivable | 12,500 | |
| 3000 | Sales revenue | 10,000 | |
| 2700 | Output VAT | 2,500 |
When the invoice is paid, the account receivable is reversed:
| Account | Account Name | Debit | Credit |
|---|---|---|---|
| 1900 | Bank | 12.500 | |
| 1500 | Accounts receivable | 12,500 |
