What Makes a Receipt Acceptable
The exact fields Odyssey checks for, and the extra step for cash, check, and payment apps.
Every receipt needs these
| Requirement | What it means |
|---|---|
| Vendor information | The business, store, or provider you paid. |
| Date of transaction | Must match the expense date you enter in Odyssey. |
| Itemized list | Each item or service listed separately with its own price — not a lump total. |
| Total amount | Including tax and fees. |
| Method of payment | Card, debit, cash, check, etc. Gift cards and rewards points alone don't count. |
| Proof of payment | Something on the document showing it was actually paid — "Paid," a zero balance, or payment details. |
Only one document can be uploaded per request. If what you have is spread across more than one file — an invoice and a separate payment confirmation, for instance — combine them into a single PDF or image first.
Paying with cash or check
This is the rule that catches people most often: a receipt for a cash or check purchase must be generated by the vendor's own point-of-sale or invoicing system — not handwritten, and not typed up afterward in a word processor. This applies regardless of the amount. It needs to show:
- Vendor name and contact info, printed or system-populated (not handwritten)
- A transaction date and time recorded automatically by the system
- An itemized description with line-item amounts
- A transaction or confirmation number assigned by the vendor's system
- A total that matches the sum of the line items
Small vendors without a POS system
Odyssey does allow a word-processor-style receipt or invoice from a small provider — but only with extra proof of payment attached, regardless of what payment method the document says was used. A document falls into this category if it's missing system-generated elements like a transaction ID, terminal number, approval code, or automatic timestamp.
To go with it, submit one of:
- A bank or credit card statement showing the account holder's name, the vendor (or a recognizable variation), the matching amount, and the date.
- A digital payment confirmation screenshot (see below).
What does not count as additional proof: a second copy of the same receipt, a letter from the vendor saying they were paid, or a photo of cash or an uncleared check.
Paying through a payment app
If you paid with Venmo, PayPal, Cash App, Zelle, or something similar, attach a screenshot of the completed transaction showing the payment status, date and time, transaction ID or confirmation number, and the recipient, where available. In each app that's usually one or two taps past the transaction itself — on Venmo, open the payment and select More Information; on PayPal, View Details; on Cash App, the entry under the Activity tab; on Zelle, the transaction's own details screen.
