Double-check that you have sent the email to the correct Lightyear email address, and that it does not contain any typos.

Check whether the invoice format is supported by Lightyear. Supported formats are PDF, JPG, and PNG. Unsupported formats, such as TXT, Word, ZUGFeRD, or XML, cannot be processed, and Lightyear will automatically redirect these to your redirect email address. Check your redirect email's inbox and spam folders to see if the document ended up there. Don't have a redirect email set up? Check out our guide on how to set one up.

Check whether the invoice has been successfully processed and routed elsewhere. Lightyear distinguishes between invoices and statements — if a forwarded document is identified as a statement, it will be routed to the Statements area rather than the Invoices or Approvals queue. Check the Statements tab and the Approval tab for the document.

If you have an internal firewall, make sure it is not blocking .cloud email addresses.

Test your auto-forwarding rule by sending an invoice directly to your Lightyear email address. If it appears in Lightyear but invoices from your company mailbox do not, review and correct the auto-forwarding rule.

Ensure that suppliers are sending invoices as PDF attachments rather than as links to view or download the invoice. Lightyear cannot process emails that do not include a PDF attachment.

Verify that suppliers are not using no-reply or link-sender email addresses to send invoices. Lightyear may not ingest emails sent from such addresses.
