Invoices Are Not Created
Rerun does not have the ability to pay open invoices created in your accounting software.
When you run a transaction in Rerun and sync it over to Xero, Rerun will create a paid invoice associated with that customer. The invoice will have an invoice number generated by Xero, and the Rerun transaction ID will appear as the reference number. The date and due date of the invoice will appear as the date payment was processed in Rerun.
When you're finished running the transactions for the day, click the "Sync" button found on the bottom of all Rerun tabs. This will sync all of your payments for that time frame over to your accounting software.
Please Note: Make sure you are set up with your accounting software by going to the Setup Assistant in the top right drop-down under "Welcome, your name", or go to the Settings tab > Sync.
