📝 Quick answer: An invoice is a payment request sent before payment. A receipt is a payment confirmation sent after payment. Same transaction — opposite sides.

The transaction lifecycle
In any sale, both documents have a place:
- Quote (optional) — estimate of the cost before work begins
- ↓
- Work delivered or product shipped
- ↓
- Invoice — sent to request payment
- ↓
- Customer pays
- ↓
- Receipt — confirms payment was received
You always issue an invoice. You only issue a receipt if the customer paid in cash, made a partial payment, or specifically requests one. For card or bank transfer payments, the bank/Stripe statement often serves as the receipt.
When you need an invoice
Send an invoice whenever:
- You've delivered a service or product to a B2B customer
- You're working with payment terms (Net 15, Net 30, etc.)
- You need to track who owes you money
- The customer needs proof for their accounting
- You're billing for tax-deductible services
When you need a receipt
Issue a receipt when:
- You receive cash payment (most important — no other paper trail)
- You take partial payment / deposit
- The customer requests one for their records
- The transaction is legally required to have one (rent, in many jurisdictions)
- You're handling refunds (the receipt proves what was originally paid)
Can you use the same document?
Yes — many small businesses use a "paid invoice" as both. When the customer pays an invoice, you simply mark it as paid (with a date and method) and re-send the same document. It now functions as both invoice and receipt. This is acceptable in most jurisdictions for simple transactions.
For cash payments, however, always issue a dedicated receipt. The invoice was never officially "issued" if cash changed hands at the moment of sale.
Real-world examples
Example 1: Freelance designer
A web designer completes a logo for a startup. They:
- Send an invoice for $500, Net 15 terms
- 15 days later, the startup pays via Stripe
- Stripe's confirmation email serves as the receipt (no separate document needed)
Example 2: Cash sale at a market
A craft seller at a farmers market sells a $40 bowl. They:
- Hand the customer a receipt showing item, price, payment method (cash), and date
- No invoice was ever issued — payment was instant
Example 3: Construction project
A contractor working on a kitchen remodel:
- Sends an invoice for $5,000 deposit (50% upfront)
- Customer pays the deposit by check
- Contractor issues a receipt confirming the deposit
- After completion, contractor sends a final invoice for the remaining $5,000
- Customer pays; final receipt issued

Frequently asked questions
Is an invoice a proof of payment?
No. An invoice is proof of a payment request. A receipt is proof that payment was made. Use a receipt or bank statement to prove payment occurred.
Can a receipt be used as an invoice?
Not really — a receipt only confirms payment, it doesn't request it. However, a "paid invoice" (an invoice marked as paid) often serves both purposes for the same transaction.
Do I need both an invoice and receipt for tax records?
Generally yes for businesses. The invoice records the income; the receipt proves the customer actually paid. Tax authorities may ask for either or both during an audit.
What's a "tax invoice" vs a regular invoice?
A tax invoice (common in Australia, Canada, UK) is a special invoice that includes the supplier's tax registration number and breaks out tax separately. Required when both parties are tax-registered for VAT/GST claiming.
