Invoice due dates for automatically generated invoices
OfficeRnD automatically charges invoices on their Due Date if the client has saved payment details, such as Direct Debit or a credit card. Automatic charging will not occur before the due date. To adjust this configuration, go to 
Settings > Billing > Invoicing, and modify the settings that determine when invoices are generated and their payment terms.
When customers purchase a product or service, you can configure the number of days before the day of use to charge them. To do that:
Go to
Settings > Experience Hub > Public Pages.Enter a number in the Invoice Due Date field.
The Invoice Due Date setting determines the due date that will be applied to invoices only when they are automatically generated through Purchase Flows.
The timing of invoice generation and charging depends on how your Purchase Flows are configured in Settings > Billing > Purchase Flows.
Charge invoices immediately after purchase: If your Purchase Flow is set up to collect payment details, generate an invoice, and charge it immediately, the invoice will be charged as soon as the purchase or booking is made. In this configuration, the system charges the invoice immediately, regardless of whether a due date is specified.
Charge invoices on the Invoice Due Date: If you prefer to charge invoices on their due date, follow these steps:
In your purchase flow, turn off the option to charge invoices immediately.
Go to
Settings > Billing > Billing Rules and ensure automated charging is turned on.
The "Pending" payment entry in the Payments section appears only after the charge occurs, not before.
