Mark as paid allows you to quickly record a payment for a billable item. This feature will simply update the billing status of the unbilled item to “Paid”.
You can print receipts from mark as paid operations. The receipt includes a list of the specific items being changed, as well as an optional note and amount.
Limits
Mark as paid is intended to be a simple system for recording offline payments. Mark as paid operations will not be included in the customer’s balance - this is calculated from invoices and invoice payments only. Furthermore, mark as paid will not be included in sales or tax reports.
For more advanced billing functionality, such as line-item pricing, taxes, and discounts, please use invoices.
