Customers who normally pay at pickup can have an individual invoice changed to an account invoice, allowing payment at a later date or in instalments. This guide shows you how to create an account invoice for a cash customer.
Step 1: Change the Account Type
- Open the invoice for the customer.
- Click the button below Account Type to change from Cash to Account.
- This can be done at any stage before processing the invoice.

Step 2: Process the Invoice
- Complete the invoice as normal with all line items.
- Click Process — the invoice will finalise with a balance due.
- The customer will now show an account balance.

Step 3: Verify the Account Balance
- Look up the customer record.
- You will see the account balance owing.

Step 4: Record Payment (When Received)
- When the customer pays, create a Customer Payment to allocate the payment to the invoice.
- See How to Allocate a Payment to an Invoice for details.
Good to Know
- Changing the account type must be done before processing the invoice.
- Once processed as an account invoice, the customer’s balance will update to reflect the amount owing.
- You can run debtor reports to track all outstanding account balances across your customer base.
