Receipts Definition: What a Receipt Is, Types and What to Keep
Receipts definition in plain English: what a receipt is, how it differs from an invoice, the main types and which ones a business must keep in 2026.

The receipts definition is simple: a receipt is a written or digital record that confirms a payment was made, showing who was paid, how much, when and for what. It is proof that money changed hands. For a business, it is also the evidence behind almost every expense you claim.
That is the short version. The rest of this guide covers the parts people actually search for: how a receipt differs from an invoice, the main types, and which receipts a business must keep (and for how long) in the US, UK and EU.
TL;DR: Receipts definition and what to keep
A receipt is proof of payment. A valid business receipt shows the seller, the date, the amount and what was bought. An invoice asks for payment; a receipt confirms it. Keep receipts for every business expense you plan to deduct, for 3 to 10 years depending on your country. Digital copies are generally accepted if they are legible and complete.
Receipt, invoice and bank statement compared
| Document | What it is | Proves payment? | Typically enough on its own for tax? |
|---|---|---|---|
| Receipt | Confirmation that a payment was made | Yes | Usually yes, if it shows seller, date, amount and items |
| Invoice | A request for payment, issued before or at the time of sale | No, unless marked as paid | Often yes for VAT, plus proof of payment |
| Bank or card statement | A record of money moving through your account | Partly | Rarely; it lacks item detail and the seller's tax data |
| Order confirmation | Confirms an order was placed | No | No, unless it also shows payment |
Receipts Definition: What Counts as a Receipt?
In everyday use, a receipt is the slip you get at a till. In accounting and tax terms, it is broader. A receipt is any document issued by a seller that acknowledges payment has been received. It can be printed, handwritten, emailed or generated inside an app.
The format matters less than the content. A crumpled thermal slip and a PDF in your inbox are both receipts if they carry the right details. A photo of a receipt is a copy of one, and most tax authorities accept that too (more on this below).
What information should a receipt contain?
A receipt that will survive an audit usually includes:
- The seller's name and, where relevant, address and tax or VAT number
- The date of the transaction
- The total amount paid and the currency
- A description of the goods or services bought
- Tax charged, such as VAT or sales tax, shown separately where applicable
- The payment method, for example cash or card
If a receipt is missing one of these, you can often fill the gap with a note. A restaurant slip with only a total, for instance, should be paired with a short note on who attended and why. That matters most for meals and entertainment.
What Is the Difference Between a Receipt and an Invoice?
An invoice is a request for payment. A receipt is proof of payment. The invoice comes first, the receipt comes after the money moves.
Things get blurry because many businesses send one document that does both. An invoice stamped "paid" works as a receipt. Online subscriptions often send a "receipt" that is legally a paid invoice with a VAT number on it.
For VAT purposes in the EU, the rules on what an invoice must contain come from the VAT Directive (2006/112/EC), and each member state adds its own details. If you reclaim VAT, you generally need a proper VAT invoice, not just a till slip with a total.
Is a bank statement a receipt?
No. A bank statement shows that money left your account, but not what you bought or what tax was included. Tax authorities treat it as supporting evidence, not as a replacement for the receipt.
Types of Receipts You Will Meet in a Business
Most small businesses handle several kinds of receipts every week. The table below groups the common ones.
Common types of receipts
| Type | Example | Watch out for |
|---|---|---|
| Sales receipt | Till slip from a shop or restaurant | Thermal paper fades within months |
| Itemized receipt | Supermarket or hardware store receipt with line items | Needed to separate business from personal items |
| Card payment slip | Terminal printout | Often shows only the total, not the items |
| Email receipt | Order or subscription confirmation in your inbox | Easy to lose in a busy mailbox |
| Paid invoice | Supplier invoice marked paid | Check it shows payment, not just a due date |
| Handwritten receipt | Cash purchase from a market trader or tradesperson | Needs date, amount, seller name and signature |
| Petty cash voucher | Internal slip for small cash spend | Attach the original receipt where possible |
| Travel receipt | Hotel folio, train ticket, boarding pass | Hotel bills are often required in full by tax authorities |
Paper receipts
Paper is still common at tills, markets and taxis. The main problem is durability. Thermal receipt paper fades with heat and light, so a slip that looks fine today may be blank when an accountant asks for it next year. Photograph paper receipts the day you get them.
Digital and email receipts
Software subscriptions, online orders, flights and ride-hailing all send receipts by email, often as a PDF attachment. They are easy to generate and easy to lose. If you want to see how automated tools handle this without compromising privacy, read our guide on why an expense app should only have read-only access to your inbox.
Handwritten and informal receipts
A handwritten receipt is valid when it contains the essentials: seller, date, amount and what was bought. Informal ones are where disputes happen, so ask the seller to sign and add contact details.
What Receipts Must a Business Keep?
The practical rule: keep a receipt for every expense you want to deduct, every VAT amount you want to reclaim and every purchase that affects your accounts. If you cannot show evidence for a cost, a tax authority can disallow it.
That includes the boring items. Parking, software subscriptions, small supplies and coffee on a client trip add up over a year, and they are the first things to go missing.
Which receipts does the IRS require?
The IRS says in Publication 463 that you need documentary evidence, such as receipts, for travel, gift and car expenses of $75 or more, and for any lodging expense regardless of amount. In practice, keeping every business receipt is safer than relying on that threshold. The IRS also states in Publication 583 that records should support the income and deductions on your return.
How long should you keep receipts?
Retention periods differ by country. Here are the main ones as of 2026:
Typical receipt retention periods
| Country or region | General rule | Source |
|---|---|---|
| United States | 3 years from filing; 6 years if you under-report income by more than 25%; 7 years for certain bad debt or worthless securities claims | IRS |
| United Kingdom (sole traders) | 5 years after the 31 January self assessment deadline for that tax year | HMRC |
| United Kingdom (limited companies) | 6 years from the end of the last company financial year the records relate to | HMRC |
| Switzerland | 10 years for accounting records and vouchers | Swiss Code of Obligations |
| EU member states | Set nationally; often 6 to 10 years | National tax authorities |
Check your local rule
These are general guidelines, not legal advice. Retention periods change and can be longer for VAT records, employment records or property. If your business operates across borders, confirm the rule with your accountant or national tax authority.
UK sole traders also face digital record-keeping rules. Our guide to HMRC Making Tax Digital receipt requirements explains what that means for how you store receipts.
Are digital copies and photos of receipts valid?
Generally yes. HMRC says you can keep digital copies of paper receipts, such as scans or photos, as long as they are readable and complete. The IRS accepts electronic storage under Revenue Procedure 97-22, provided the system produces legible and accurate copies and you can retrieve them on request.
The word that matters is legible. A blurry photo cropped at the total does not meet the standard. Capture the whole receipt, in good light, and check the text is readable.
What Happens If You Lose a Receipt?
It is not always fatal, but it is costly. Your options, roughly in order of preference:
- Ask the seller for a duplicate; online stores and subscription services can usually resend one
- Search your email for the order or payment confirmation
- Use your bank or card statement as supporting evidence, along with a written note of the purpose
- Write a memo describing the expense, date, amount and business reason (a last resort, and some tax authorities may not accept it)
Lost receipts also create downstream cost. One ReceiptFlow customer paid about $8,000 for a year-end bookkeeping cleanup because expenses had not been kept organized. If you want to understand what drives bills like that, see our breakdown of how to avoid a bookkeeping cleanup bill.
How to Keep Receipts Without the Shoebox
The shoebox method works until it does not. A better system has three parts: capture the receipt at the moment of purchase, categorize it as you go and store it somewhere searchable.
A simple routine that works for most small businesses:
- Photograph paper receipts the same day, before they fade or get lost
- Forward or auto-collect email receipts into one place
- Tag each receipt with a category, such as travel, software or meals
- Review weekly, not at year end
- Export a clean set for your bookkeeper or accountant each period
Where a tool fits in: ReceiptFlow is a receipt capture layer, not a full accounting system. It pulls receipts from Gmail and Outlook (including PDF attachments, with read-only access) and lets you send a photo through WhatsApp, where the AI extracts the vendor, amount, date and category. Everything lands in one dashboard, and a one-click export gives your accountant a clean record to work from in whichever accounting software they use, such as Xero, QuickBooks or Sage.
Expensify focuses on team reimbursements, whereas ReceiptFlow specializes in email and WhatsApp receipt capture. If you want to see why the messaging route works, read why we built a WhatsApp receipt tracker.
A real-world example
One ReceiptFlow customer is a frequent traveler who used to lose afternoons processing receipts after each trip. Another is an accountant who was impressed by a client's organized records and asked what system they used. A third accountant uses ReceiptFlow for their own clients. The pattern is the same: when capture happens early, the cleanup disappears.
What it costs
ReceiptFlow offers a 30-day free trial with no credit card, and setup takes minutes. Paid plans start at €7.99 per month for 50 receipts, or €21.99 per month for 400 receipts plus team features, where you can add team members, see their receipts and approve them. It was built in Switzerland. Multiple email accounts per user are supported.
If you are weighing automation more broadly, our guide to automating expense management covers the wider workflow.
Bottom line
A receipt is proof of payment, and a business should keep one for every expense it claims. The format can be paper or digital. What matters is that it is complete, legible and findable years later.
Receipts Definition FAQ
Frequently Asked Questions
What is the definition of a receipt?
A receipt is a written or electronic document issued by a seller that confirms payment was received. It normally shows the seller, date, amount and what was purchased, and serves as proof of purchase for customers and as evidence for business expenses and tax.
What is the difference between a receipt and an invoice?
An invoice requests payment and is issued before or at the time of sale. A receipt confirms that payment has been made. An invoice marked as paid can serve as both, which is common with online services.
What information must a receipt show?
At minimum: the seller's name, the date, the amount paid and a description of what was bought. For VAT or sales tax claims, the tax amount and the seller's tax number are usually needed as well.
How long should a business keep receipts?
It depends on the country. The IRS generally says 3 years from filing for most US records, and up to 6 or 7 years in specific cases. HMRC requires 5 years after the self assessment deadline for sole traders and 6 years for companies. Switzerland requires 10 years for accounting records.
Is a photo of a receipt acceptable for tax purposes?
Generally yes. HMRC accepts scans and photos of paper receipts if they are legible and complete, and the IRS accepts electronic records that are accurate and retrievable. Check local rules if you operate in another country.
Can I use a bank statement instead of a receipt?
A bank statement is supporting evidence, not a substitute. It does not show what you bought or the tax included, so tax authorities usually expect the receipt or invoice too.
