Spendesk Receipt and Invoice Email Workflow

The Inbox-to-Spendesk Gap

Spendesk provides both destinations, but source messages still need the correct next-action decision:

•A card-payment receipt and an unpaid supplier invoice belong in different email workflows

•One supplier can send both receipt and invoice document types

•Duplicate detection and payment export state can block a later receipt attachment

•Large batches and unclear files can create OCR, assignment, or upload errors

Route Each Document to the Correct Spendesk Workflow

Connect the source inbox, review the document and its next action, and route it to the current company address for receipts or invoices.

Next-action routing: Choose Marvin for card evidence or bills Inbox for an invoice request

Review before delivery: Keep portal-only notices, duplicates, and unclear payment context visible

Historical catch-up: Find older receipts and invoices that still need a Spendesk path

Separate recurring rules: Use distinct sender, subject, and document patterns for each destination

What Spendesk Does After Delivery

Marvin attempts to attach receipt evidence to a Spendesk payment. On Essentials, Growth, and Premium, the supplier invoice address creates draft requests in Inbox; Starter does not include this feature.

•The receipt address is available in Payments and uses a company-specific receipts+ value

•On Essentials, Growth, and Premium, Inbox provides a separate bills+ invoice address

•Supplier invoice forwarding is available on Essentials, Growth, and Premium, not Starter

•Marvin email guidance names PDF; broader upload guidance also accepts JPG and PNG

•Spendesk creates one invoice request per attachment and warns about messages with more than 10 invoices

•Unrecognized invoice senders can identify a Spendesk user in CC for assignment

•Exported payments may no longer accept receipt attachment or modification

Do not mix the destinations: Copy the live address from the correct Spendesk screen and confirm whether the document is payment evidence or a supplier invoice request.

Set Up the Spendesk Email Workflow

Choose receipt or invoice intake

Copy Marvin from Payments or, on an eligible plan, the supplier invoice address from Inbox.

Connect the source inbox to Expensent

Use the mailbox where the corresponding receipts or supplier invoices arrive.

Send one controlled document

Confirm the receipt attaches to the right payment or the invoice creates the expected draft request.

Create a destination-specific rule

Automate only the sender, subject, and document pattern that completed the intended workflow.

Spendesk Email Routing and Expensent FAQ

Is Expensent a native Spendesk integration?

No. Expensent routes selected emails to company-specific Spendesk addresses. Spendesk controls matching, requests, approvals, and export.

Which Spendesk address should I use?

Use Marvin from Payments for card evidence. Use bills Inbox for supplier invoice requests on Essentials, Growth, and Premium; Starter does not include invoice forwarding.

Can suppliers send invoices directly?

Yes, on Essentials, Growth, and Premium. Spendesk documents direct supplier delivery and user assignment, but says invoice forwarding is not available on Starter.

Which receipt formats are accepted?

Spendesk documents PDF for Marvin email and PDF, JPG, or PNG for broader upload. Current official pages conflict on maximum size, so follow the live account validation.

Will every emailed receipt attach automatically?

No. Verify the target payment, file, duplicate state, and whether the payment remains editable after export or validation.

How Inbox-to-Accounting Email Workflows Work

Expensent connects to your email inbox and uses AI to surface likely invoice and receipt emails. Each document is grouped by what needs to happen next: ready to forward with a PDF attachment, needs a download from the vendor portal, needs your review, or not an invoice. You review the queue and decide what happens next.

Direct Forwarding Where Compatible

For destinations that accept the Expensent-generated message, forward a selected document with one click or create a rule from a reviewed sender and subject pattern. When a tool requires a stricter subject or body format, use the review and handoff path stated on its integration page.

Works With Many Accounting Platforms

Use direct delivery with compatible destinations such as QuickBooks Online, Xero, Expensify, FreshBooks, Ramp, Brex, BILL, Dext, SAP Concur, Wave, Zoho Expense, Hubdoc, Shoeboxed, and others. For a stricter workflow such as Tallie's clean email format, prepare the evidence and complete the documented handoff. Each platform controls how receipts are received, processed, extracted, or matched.

Privacy and Security

Expensent uses OAuth authentication to connect to your inbox - your password is never shared. AI prefilters on email metadata only, so personal emails are filtered out without their content ever being read. You control which documents advance and where supported delivery goes.
