Hi Accounts_2
Apologies for the late response. I understand that you're encountering error messages while trying to import sales invoices. This can indeed be painful, but no worries, I've got you covered. Please check out this link for detailed troubleshooting steps for resolving import errors. If you're still receiving errors after following the steps, you might want to consider creating an export/import template. This can help ensure that all required fields, like item numbers, are correctly formatted and included.
Feel free to reach out if you need further assistance.
Cheers,
Princess
