Pay Invoice Error

The link opens the screen directly in the Integration Dashboard.

How the screen appears in the Integration Dashboard.

Posted invoices with no payment entry recorded.

• The payment journal is unset for the payment method used. This is the leading cause.
• The invoice is still a draft — an unposted invoice cannot be paid. Check your status order: posting must always come before paying.
• The invoice is already paid by hand in Odoo.
• The accounting period is locked for the payment date.

If you have mark the invoice as paid without a payment entry turned on, this step should not run at all — remove the statuses from the create-payment list.

Read the Odoo message on the row — it says exactly what is missing. Fix the cause in Odoo or in your settings, then press Retry on the row, or Retry Fix All if the cause is shared across every row.
