About SendInvoice Credit Memo Generator
What is SendInvoice Credit Memo Generator?
SendInvoice Credit Memo Generator is a free, web-based tool for creating professional credit memos (also called credit notes) that reduce customer account balances. It enables businesses to document returns, refunds, billing corrections, discounts, and overpayments with automatic accounting integration. Part of the SendInvoice platform developed by Assemblysoft Ltd, UK.
What is a Credit Memo?
A credit memo (also called credit note, credit memorandum, or credit voucher) is a commercial document issued by a seller to a buyer that reduces the amount the buyer owes. It's the opposite of an invoice.
Key Characteristics
- Reduces Amount Owed: Credits customer's account, lowering outstanding balance
- Opposite of Invoice: Invoices add to amount owed; credit memos subtract from it
- References Original Invoice: Always links to the invoice being adjusted
- Accounting Impact: Reduces accounts receivable and revenue in seller's books
- Tax Adjustment: Recalculates VAT/sales tax based on credited amount
- Can Be Partial: Doesn't need to match full invoice amount
- Refund or Future Credit: Can result in cash refund or credit toward future purchases
Credit Memo vs Debit Memo vs Refund
| Attribute | Credit Memo | Debit Memo | Refund |
|---|---|---|---|
| Direction | Seller credits buyer | Seller debits buyer (increases amount owed) | Seller returns cash to buyer |
| Effect on Balance | Decreases amount buyer owes | Increases amount buyer owes | Returns money already paid |
| Accounting Impact (Seller) | Reduces revenue, reduces A/R | Increases revenue, increases A/R | Reduces cash, reduces A/R |
| Common Reasons | Returns, billing errors (overcharge), discounts | Additional charges, undercharges, interest | Return of payment for cancelled order |
| Money Movement | No immediate cash movement (credit to account) | No cash movement (adds to amount due) | Immediate cash returned to buyer |
| Invoice Reference | Yes - references invoice being credited | Yes - references invoice being adjusted | May reference invoice or payment receipt |
| Future Application | Can be applied to future purchases | Must be paid by buyer | Cannot be reused (money already returned) |
| Tax Treatment | Reduces tax owed by seller | Increases tax owed by seller | No additional tax impact |

Accounting Impact of Credit Memos
Double-Entry Bookkeeping
Credit memos affect the seller's books as follows:
Journal Entry for Credit Memo (Seller's Books)
| Account | Debit | Credit |
|---|---|---|
| Sales Revenue / Sales Returns & Allowances | £240.00 | |
| Accounts Receivable | £240.00 |
Effect on Financial Statements
| Financial Statement | Impact |
|---|---|
| Income Statement | Reduces revenue (or increases sales returns & allowances expense) |
| Balance Sheet - Assets | Reduces accounts receivable (customers owe less) |
| Balance Sheet - Liabilities | If cash refund, reduces cash; if account credit, no immediate liability impact |
| Cash Flow Statement | If cash refund, reduces operating cash flow |
| Tax Return | Reduces taxable income and VAT/sales tax owed |
Tax Implications
- VAT/Sales Tax Reduction: Seller reduces tax owed to tax authority
- VAT Return Adjustment: Must be reported on VAT return in period issued
- Input Tax Recovery (Buyer): If buyer claimed VAT, must repay if goods returned
- Revenue Recognition: Reverses revenue recognized on original invoice
- Tax Credit Carryforward: Excess credits can reduce future tax liability
Accounts Receivable Aging Impact
Credit memos affect A/R aging reports:
- Reduces Outstanding Balance: Customer's total A/R decreases
- May Clear Old Invoices: Credit can be applied to oldest unpaid invoices first (FIFO)
- Improves Aging Profile: Reduces amounts in 60+, 90+ day buckets if applied to old invoices
- Credit Balance: If credit exceeds amount owed, customer has negative A/R (credit balance)
Credit Memo vs Invoice Adjustment
When to Use Credit Memo
- Original invoice has been sent to customer
- Customer has already paid (partial or full)
- Need to maintain audit trail
- Accounting period of original invoice has closed
- Legal/regulatory requirement for credit documentation
- Return or cancellation after delivery/service start
When to Adjust Original Invoice Instead
- Invoice not yet sent to customer
- Customer has not paid
- Error discovered immediately after invoicing
- Accounting period still open and can be corrected
- Internal correction before customer sees invoice
- Simplifies record-keeping (one document vs two)
Best Practice
Never delete or modify an issued invoice. Always issue a credit memo to correct invoices that have been sent, paid, or recorded in closed accounting periods. This maintains audit trail integrity and complies with tax regulations.
Legal & Regulatory Requirements
Tax Authority Requirements
| Country/Region | Credit Note Legal Requirements |
|---|---|
| United Kingdom (HMRC) | Must include business name, address, VAT number, customer details, credit amount, VAT amount, reference to original invoice, reason for credit. Must be issued within time limits for VAT adjustment. |
| United States (IRS) | No specific federal requirement for credit memos, but recommended for audit trail. State sales tax laws may require credit memos to adjust sales tax reported. |
| European Union (VAT Directive) | Credit notes must reference original invoice, state reason, show VAT adjustment. Must be issued in same VAT period or next if goods returned. |
| Canada (CRA) | Credit notes must show GST/HST adjustment, reference original invoice, include business number. Required for GST/HST return adjustments. |
| Australia (ATO) | Tax invoices can be adjusted with credit notes. Must show ABN, GST amount, reason for adjustment, reference to original invoice. |

Credit Memo Numbering Best Practices
Recommended Numbering Formats
| Format | Example | Advantages |
|---|---|---|
| CM-[Year]-[Sequential] | CM-2025-042 | Clear year identification, easy sorting, professional |
| CN-[Sequential] | CN-10542 | Simple, continuous numbering across years |
| CREDIT-[YYYYMMDD]-[Seq] | CREDIT-20250115-03 | Date embedded in number, sortable chronologically |
| [InvoiceNum]-CR-[Seq] | INV12345-CR-01 | Direct link to original invoice number |
| [CustomerCode]-CM-[Seq] | ACME-CM-089 | Customer identification embedded |
Numbering Rules
- Sequential: Never skip numbers (creates audit red flags)
- Unique: Each credit memo gets one-time-use number
- Separate from Invoices: Use different series than invoices
- Negative Sign: Some systems use negative invoice numbers (e.g., -INV12345)
- No Reuse: Never reuse voided credit memo numbers
- Consistent Format: Use same format across all credit memos
Common Mistakes to Avoid
- No Invoice Reference: Failing to link to original invoice makes tracking impossible
- Missing Reason: Not stating why credit is issued leads to confusion and disputes

- No Audit Trail: Not documenting reason and supporting evidence (photos, emails)
- Duplicate Credit: Issuing multiple credits for same issue

- Incorrect A/R Application: Not properly applying credit to customer's account
