TL;DR

Moss gives each organization separate addresses for card receipts and supplier invoices. Copy the exact value from the Receipts or Invoices tab instead of reconstructing the address.

Receipt emails go to an address shaped like receipts+organization-name@getmoss.com and can match Moss card transactions. Supplier invoices go to the invoices+ organization address and enter the invoice workflow.

The Receipt Inbox accepts PDF, JPG, JPEG, and PNG files up to 20 MB, while Expensent currently sends PDF, JPG, and PNG attachments up to 3 MB each. Review the result inside Moss before accounting or payment.

1. Choose the receipt or invoice destination

Open the Moss Document Inbox and choose the tab that matches the job. The Receipts tab shows the organization-specific receipt address for evidence that should attach to Moss card transactions. The Invoices tab shows a different organization-specific address for supplier invoices that need the invoice workflow.

The address formats include the organization name, but the live value is authoritative. Copy it from the current account. Do not convert a receipts+ address into an invoices+ address by editing the text, because naming and organization details can change.

2. Prepare a document both systems can use

Moss documents PDF, JPG, JPEG, and PNG in the Receipt Inbox, with a maximum of 20 MB per file and up to twenty files in a drag-and-drop batch. Expensent currently supports PDF, JPG, and PNG attachments up to 3 MB each, so an Expensent handoff must fit the narrower limit.

Use the original legible document when possible. A card receipt should show the merchant, date, amount, and tax evidence needed to identify the purchase. A supplier invoice should show the supplier, invoice number, amount, currency, payment details, and due date that the finance team must verify.

Moss can optionally convert a receipt found only in the email body into a PDF. The finance team controls that setting, and Moss warns that a generated document is not guaranteed to satisfy tax requirements. Treat the generated file as reviewable evidence, not automatic proof of tax compliance.

3. Compare email with the other Moss capture methods

Email forwarding is useful when the document already arrives in a mailbox. Receipt Finder is a separate Gmail or Microsoft 365 connection for a supported merchant list and searches after a Moss card transaction occurs. Moss says it checks for up to seven days before marking the receipt missing.

Bulk upload fits a local document backlog. Send to Moss lets a phone user share a receipt from another app. Direct web or mobile attachment fits a known card transaction, and TravelPerk is a separate direct integration. The right method depends on where the evidence starts and whether the target card transaction is already known.

Email to Document Inbox: digital evidence already in a mailbox.
Receipt Finder: supported merchants in a connected work inbox after a Moss card transaction.
Bulk upload: a group of saved PDF or image files.
Send to Moss: a receipt opened in another mobile app.
Direct attachment: a known Moss card transaction.
TravelPerk integration: eligible travel evidence from the connected service.

4. Understand receipt matching and correction

Moss processes a receipt from the inbox and attempts to match it with a Moss card transaction that lacks evidence. A successful result appears as auto-matched. If confidence is lower, the Receipt Inbox can show potential matches or let the user search all transactions and attach the receipt manually.

Moss also documents duplicate handling and a correction path. A detected duplicate can be removed from the inbox with an email notification. An incorrect match can be unlinked and attached to another transaction. These controls are reasons to inspect the existing inbox item before sending the source again.

5. Use Expensent to review and route the source email

Connect the mailbox where receipts and supplier invoices arrive. Expensent can find current and historical documents, show the source and available files, and send selected evidence to the exact Moss destination configured for the organization.

Expensent creates a new message with an Expensent subject and summary body. Selected attachments are added to it, and body-only evidence appears below the summary. Moss controls whether it recognizes the attachment or the body-derived evidence, so test one representative vendor message before approving a rule.

  1. 1
    Classify the document as a card receipt or supplier invoice.
  2. 2
    Copy the exact destination from the matching Moss tab.
  3. 3
    Review the original evidence and choose supported files.
  4. 4
    Send once and inspect the Moss match or invoice entry.
  5. 5
    Approve recurrence only for the vendor and document type that worked.

6. Finish matching, approval, payment, and accounting in Moss

For a card receipt, confirm the transaction, cardholder, merchant, date, amount, tax, accounting attributes, and receipt status. For a supplier invoice, confirm supplier, invoice number, due date, amount, payment data, approval path, and duplicate state.

Expensent owns source discovery, review, and the approved email handoff. Moss owns recognition, matching, invoice handling, controls, payment, and accounting export. Keep the source message until the downstream record is complete.

9. Frequently asked questions

Can I email receipts and invoices to Moss?

Yes. Moss gives each organization separate addresses for card receipts and supplier invoices. Copy them from the corresponding Document Inbox tabs.

Does a forwarded Moss receipt always match automatically?

No. Automatic matching applies to eligible Moss card transactions. An uncertain receipt remains in the Receipt Inbox for potential-match review or manual attachment.

Can Moss capture a receipt in the email body?

Moss documents an optional setting that converts recognized body-only receipt evidence into a PDF. Finance should review the result, especially for tax use.

Does Expensent replace Moss Receipt Finder?

No. Receipt Finder is a Moss inbox connection for supported merchants and Moss card transactions. Expensent adds reviewed discovery and routing for selected current or historical messages.
