Error: The attachment must be less than 3MB
The cause:
Xero does not accept expenses with receipt attachments that are larger than 3MB.
The solution:
Replace the receipt attachment(s) with a smaller one in Pleo.
Note: When carrying out an export there are checks in place to ensure a smooth export, one of which is making sure the file is 3MB or less.
Non PDF attachments are made smaller with a compression tool.
PDF attachments will automatically fail and will fall back to the export queue to be fixed manually.
