Find the receipt rather than the delivery email.

A purchase can produce an order confirmation, a dispatch notice, an invoice and a payment receipt. Start with the document that explains what you bought and what you paid. Keep the other messages when they contain necessary context, but do not automatically turn each message into a separate expense.

For a hotel or travel booking, a confirmation may describe a reservation rather than the final charge. Check the document against the completed purchase. If the final receipt lives in a customer portal, obtain that copy instead of relying on the first booking email.

Save a complete, readable file.

If the email includes a PDF receipt, download the attachment. Open it once to confirm it is the expected purchase and includes every page. For a receipt shown in the email itself, use your email app’s available save or print-to-PDF function, then inspect what was saved. Menus vary by email app and device.

A screenshot can omit the bottom of a long email or show only an attachment preview. If you use one, verify that the merchant, purchase details, date and amount are visible. Saving a file with a useful name helps you find it again without opening several similarly named downloads.

Use a name you can recognize later.

A naming convention helps with retrieval. It does not replace the actual receipt or change the information it contains. Avoid putting confidential client details into names you may share outside your team.

Import the receipt and review the result.

Download the receipt from your email, then import the file into BillBack. Review the scanned merchant, date and amount, and add a tag and a short note before saving the expense. Check the attachment before leaving the expense: a saved amount without the right receipt will still need attention later.

Check that the correct document is attached to the correct purchase. If the email contains multiple unrelated attachments, do not assume the first one is the receipt. Keep the message itself when your reviewer needs an approval or explanation that is absent from the document.

One purchase may have several copies.

You might photograph the paper receipt on the day and later download an emailed copy. Compare the merchant, date, amount and available transaction details before adding another expense. The second copy may improve the supporting record without representing a second purchase.

Keep a simple distinction between files collected and expenses submitted. Re-downloading a document should not mean claiming it again. BillBack can warn about a possible duplicate while adding an expense; review the match rather than treating the warning as proof either way.

Review the document in the final report.

When you create a report, open the receipt pages and confirm the saved file produced readable supporting images. Compare the number of expenses you selected with the record you intend to send, and resolve any missing-image warning.

An organized inbox is useful, but the submission still needs to satisfy the reviewer. Cornell’s documentation illustrates that supporting context can matter alongside proof of payment. Follow your organization’s requirements for the original files and any approvals, and keep the submitted report where you can locate it later.
