Here is a guide to manually putting invoices into a "paid" status without actually processing any payments.
You can quickly mark invoices as "Paid" from the Invoice List screen. In ERP, go to Sales > Invoice Processing.
Click More Filter.
Scroll down to Status and select Outstanding. Click Apply. All Outstanding invoices will now be displayed.
Select the invoices you want to mark as paid and click Action. Click Pay Balance in Full.
The Pay Invoice menu will pop up, prompting you to select the payment method. You will note that you can select AuthorizeNet as a payment method, but this will just record that the invoice was paid - outside of DigitBridge - by credit card.
Caution: You cannot actually process a payment here; this is just a tool to quickly update the status of invoices to paid.
Once you’ve selected your payment settings, click Pay.
After a minute or two, click refresh (upper right) or refresh your browser screen. You will notice that all the invoices you had previously selected are now marked Paid.
