B2B Payments uses the default payment method set in your QuickBooks Commerce account and therefore syncs with the accounting ledger associated with it.
Each payment done via B2B Payments displays "B2B Payments" as a payment reference and syncs with Xero and QBO.
We are working on improving the functionality and ensuring that the sync becomes better in upcoming versions.
Can I see that a transaction is paid via B2B Payments on Xero and or QBO respectively?
No. You can only see “B2B Payments” as a payment reference in QuickBooks Commerce, not on your integrated accounting software (Xero or QBO). The paid invoice will still sync to your designated accounting ledgers in Xero or QBO as it normally would. We are working to improve our integration and will update our users on any new updates.
