This article presents some common error messages you may encounter in the invoice module when performing an invoice export with Next Connect. The error message will appear in the 'External invoice number' field.
​

!Import error

• This may be because the project/work order does not exist in the accounting system. Perform a project export or add the project manually in the accounting system.

• This may also be because the project/work order is marked as closed. Mark the project/work order as active.

• This may also be because the accounts in the invoice are missing a connection to the item number on the invoice. To read more about accounts and items, click here, select your accounting system and check under the section 'Customer invoice integration'.

!Customer error

• This may be because the customer does not exist in the accounting system. Double-check that the customer exists in the accounting system with the same customer number as in Next Project, otherwise perform a customer export or add the customer manually in the accounting system.

!Item error

• This may be because the item number in the chart of accounts does not match the item in the accounting system. To read more about items, click here, select your accounting system and check under the section 'Customer invoice integration'.
