You can now print receipts for the payments you receive. The new option -- Print Receipts -- appears in the Banking Command Centre. When you click this option, a Forms Selection window appears; you can choose between regular payment receipts and credit card Receipts. The credit card receipt prints a line for a signature.
As with any form, you can click the Customise button to open the Customise Receipts window where you can customise the receipt form.
