How do I get CiviXero to process contributions missed in the first run?
How do I get CiviXero to add a specific contribution to it's account_invoice table for consideration?


I think if you just edit and save the contribution, it should be added to this table (provided it does not end up with any error).


  How do I get CiviXero to process a specific contribution. I've tried invoice push job with contribution_id as the argument. Without the item being in account_invoice it doesn't consider it as needing being pushed.


Only the rows present in "civicrm_account_invoice" is considered by the civixero extension to push to xero. So if the contribution id is not present in this table, you need to make sure it does.

After a record is added to 'civicrm_account_invoice' table, you can use contribution_id param to push a single payment to xero.
