Enable “Accounts Receivable Only” setting (optional)

Go to Settings > Advanced Options > tick “Account Receivable Only” > click Save Settings.

• With “Accounts Receivable” option ticked, all invoices to process will be treated as sale invoices.
• When you need to process supplier’s invoice, this setting needs to be turned off again.
• Generally if you need to process both bills and sale invoices, you do not use this option.
