Payment date cannot be before Bill creation date.
This error occurs when a payment is trying to sync to Sage Intacct from Bill.com, but the payment date is earlier/before the invoice date of the bill itself. Example: invoice date of 6/20/17, payment process date 6/17/17, and the setting "payment dates must be greater than their bill dates" is enabled in Sage Intacct.
- Edit the bill in Bill.com to have an invoice date earlier than the payment process date and sync
- Void the payment in Bill.com and re-create a payment with a process date after the invoice date of the bill and sync
- uncheck the setting "payment dates must be greater than their bill dates" in Sage Intacct, under Configure Accounts Payable
