The invoice transaction object contains information about transactions against an invoice.
Use the Take Payment functionality to log payments and refunds against invoices in Current RMS.
We don't recommend using invoice transaction objects when linked to Xero or QuickBooks Online. Transactions logged in Xero and QuickBooks Online are not accessible in document layouts or discussion templates.
When integrated with QuickBooks Online, there's no facility to record payments in Current RMS.
When integrated with Xero, the Take Payment function posts payments across to Xero. Only transactions recorded using the Take Payment function can be accessed on document layouts and discussion templates. Transactions logged directly in Xero are not accessible in document layouts or discussion templates.
