Quick Summary: The Key Difference
Invoice:
A document requesting payment BEFORE the customer pays. It's a bill.
Receipt:
A document confirming payment AFTER the customer has paid. It's proof of payment.

What is an Invoice?
An invoice is a commercial document that a seller sends to a buyer after providing goods or services. It itemizes the transaction and requests payment.
Invoice Characteristics:
- Payment Request: Formally asks the customer to pay
- Payment Terms: Specifies when payment is due
- Detailed Breakdown: Lists all items/services, quantities, prices
- Payment Instructions: Tells customer how to pay
When to Use an Invoice:
- • After completing a service or project
- • After delivering products (in B2B transactions)
- • For recurring services (monthly, quarterly billing)
- • When offering payment terms (not requiring immediate payment)

What is a Receipt?
A receipt is a document that confirms a payment has been made and received. It serves as proof that the transaction is complete.
Receipt Characteristics:
- Payment Confirmation: Proves payment was made
- Payment Details: Shows date paid, amount, method
- Transaction Closed: Indicates completion
- Proof of Purchase: For returns, warranties, taxes
When to Use a Receipt:
- • Immediately after receiving payment
- • For cash transactions
- • For credit card payments
- • For retail purchases
- • After invoice is paid (receipt references invoice number)
Real-World Examples
Example 1: Freelance Web Designer
Scenario: Designer completes website for client
Invoice Usage:
- Designer finishes website and delivers files
- Designer sends invoice: "Website design - $3,000 - Due in 30 days"
- Client reviews invoice
- Client processes payment (takes 2-3 weeks)
Receipt Usage:
- Client sends payment after 21 days
- Designer receives payment
- Designer sends receipt confirming payment received
- Client saves receipt for tax records
Example 2: Retail Store Purchase

Do You Need Both Invoice and Receipt?
Need ONLY Invoice:
- • Payment hasn't been made yet
- • Offering payment terms
- • Payment will come later
Need ONLY Receipt:
- • Payment is immediate
- • Cash transactions
- • Point of sale purchases
Need BOTH:
- • Send invoice for services
- • Client pays days/weeks later
- • Send receipt confirming payment
Common Mistakes to Avoid
Mistake 1: Calling Everything a "Receipt"
Many businesses incorrectly call invoices "receipts." This creates confusion:
- ❌ Wrong: Sending "receipt" before payment is made
- ✓ Correct: Send "invoice" before payment, "receipt" after payment
Mistake 2: Not Sending Receipts After Payment
Some businesses only send invoices and never confirm payment:
- ❌ Problem: Customers have no proof they paid
- ✓ Solution: Always send receipt when payment is received
Mistake 3: Not Referencing Invoice on Receipt
Receipts should reference the original invoice:
- ❌ Wrong: "Payment received: $5,000"
- ✓ Correct: "Payment received for Invoice #2025-042: $5,000"
Frequently Asked Questions
What comes first, invoice or receipt?
Invoice comes first (requesting payment), receipt comes second (confirming payment was received).
Can a receipt be used as an invoice?
No. A receipt proves payment was made. An invoice requests payment that hasn't been made yet. They serve opposite purposes.
Do I need to provide both invoice and receipt?
Yes, if you send an invoice and later receive payment, you should send a receipt confirming the payment. This provides complete documentation for both parties.
How long should I keep invoices and receipts?
Keep both for at least 7 years for tax purposes. Some countries require 5-10 years. Digital copies are acceptable.
