π What Is an Invoice?
An invoice is a formal document sent by a seller to a buyer requesting payment for goods or services provided.
Key Characteristics of an Invoice:

- Purpose: Request payment from the customer
- Status: Can be paid, unpaid, or partially paid
- Payment Terms: Includes due date (Net 30, Due on Receipt, etc.)

- β Customer name and contact information
- β Detailed description of goods/services
- β Quantity and price per item
- β Subtotal, taxes, and total amount due

π Example Invoice Scenario:
You're a web designer who just completed a website for a client.
You send them an INVOICE for $2,500 with payment terms "Net 30".
β’ Invoice sent: January 15, 2026
β’ Payment due: February 14, 2026 (30 days later)
β’ Status: UNPAID until client pays
The invoice requests the money but does NOT prove it was paid.
π§Ύ What Is a Receipt?
A receipt is a document given by a seller to a buyer confirming that payment has been received.
Key Characteristics of a Receipt:
- Timing: Issued AFTER payment is made

What a Receipt Must Include:
- β The word "RECEIPT" clearly displayed
- β Unique receipt number
- β Date of payment
- β Business name and contact information
- β Description of what was purchased
- β Amount paid
- β Payment method (cash, card, check, etc.)

π§Ύ Example Receipt Scenario:
Continuing the web design example above:
Your client pays the $2,500 invoice on February 10, 2026.
You send them a RECEIPT confirming payment was received.
β’ Receipt date: February 10, 2026
β’ Amount paid: $2,500.00
β’ Payment method: Bank transfer
β’ Status: PAID IN FULL
The receipt proves the transaction is complete.

β Common Questions Answered
Q: Can an invoice also be a receipt?
A: Yes, if the invoice is marked "PAID" with payment date and method. However, it's better practice to issue a separate receipt.
Q: Do I need to give a receipt if I already sent an invoice?
A: Technically no, but it's professional and recommended. Receipts give your clients proof of payment for their records.
Q: Which document do I need for tax deductions?
A: Receipts are the primary proof of payment. Keep both invoices and receipts for complete documentation.
Q: Can I edit a receipt after issuing it?
A: No. Receipts are final proof of transactions and should never be altered. If there's an error, issue a refund receipt or corrected receipt with explanation.
Q: Can I edit an invoice after sending it?
A: Only before it's paid. After payment, the invoice becomes a historical record. If changes needed, issue a credit note or amended invoice.
Q: Do I need an invoice for cash payments?
A: No, if payment is immediate. Just provide a receipt. However, for record-keeping, you might create an invoice for your files.
Q: What's a "sales receipt"?
A: A sales receipt is just another name for a receipt. It confirms immediate payment at time of sale.
Q: Can I use invoice numbers for receipts?
A: It's better to use separate numbering systems: INV-001 for invoices, REC-001 for receipts. This prevents confusion.
Q: Is a bank statement proof enough without a receipt?
A: Bank statements show money was transferred but don't detail what was purchased. You need receipts for tax deductions.
Q: What if a client loses their receipt?
A: You can issue a duplicate receipt marked "COPY" or "DUPLICATE" with the original date and details.
