"You have reached the limit of invoices you can approve".
The plan you are using in Xero is for a limited a amount of invoices only.
You can now post one combined invoice to Xero (instead of three) from iPayroll. Depending on the number of bank statement lines you receive in Xero, you may need to use Find & Match functionality in Xero to reconcile the bank statement line / s and bills in Xero.
We have a journal upload that is available to you to transfer your information into Xero.
