Debit Memo vs Credit Memo: Bank and Invoice Examples
On a deposit-account statement, a debit memo generally reduces the customer’s bank balance and a credit memo increases it. In seller-issued invoicing, a credit memo reduces what the customer owes; a debit memo increases it. Always identify the issuer, affected account and reason before deciding the accounting entry.
At a glance
Whose balance does the memo change?
Fictional educational example. Amounts are illustrative, not customer records.
| Document / issuer | Affected balance | Before | Change | After | Willow’s entry |
|---|---|---|---|---|---|
| Bank fee debit memo / bank | Willow bank deposit | $1,000 | -$15 | $985 | Dr Bank fee expense $15; Cr Cash $15 |
| Interest credit memo / bank | Willow bank deposit | $985 | +$4 | $989 | Dr Cash $4; Cr Interest income $4 |
| CM-44 / Willow as seller | Pine’s unpaid invoice owed to Willow | $1,000 | -$100 | $900 | Dr Sales allowances $100; Cr Receivables $100 |
| DM-44 / Willow as seller | Pine’s unpaid invoice owed to Willow | $900 | +$50 | $950 | Dr Receivables $50; Cr Service revenue $50 |
| Buyer debit note / buyer | Supplier adjustment requested | Depends on original invoice | Not decided by label | Confirm evidence and acceptance | Assess the underlying purchase and approved vendor credit |
The first two rows use deposit-account money-in/money-out signs. The next two use changes in the seller’s receivable.
A credit memo is not itself proof that cash was refunded. Keep its invoice application or refund reference.
Dr means debit; Cr means credit. Each illustrated posted entry balances.
Step by step.
Identify the parties
Determine whether the document is from a bank, a seller billing a customer, or a buyer communicating with a supplier.
Read the original reference
Find the bank transaction, invoice or return authorization that the memo adjusts, and confirm whether it has already been recorded.
Apply the adjustment once
Use the relevant cash, receivable or payable account and a supported offset. Keep the memo with the original record.
Bank memos use the bank’s perspective
A customer deposit is a liability of the bank. A debit to that liability reduces the amount the bank owes the customer; a credit increases it. In the customer’s business books, the same deposit account is a cash asset, so a reduction is a credit to Cash.
Fictional Willow Workshop has $1,000 before a $15 service-charge debit memo and a $4 interest credit memo. The statement ends at $989: $1,000 - $15 + $4. If neither item is already in the books, debit Bank fee expense $15 and credit Cash $15; then debit Cash $4 and credit Interest income $4. The account agreement and statement, not the word memo alone, establish the reason.
Seller-issued credit memo: reduce the customer balance
In a separate fictional example, Willow sells services to Pine Customer on invoice INV-44 for $1,000, excluding tax. Pine has not yet paid. Willow approves a $100 service allowance and issues credit memo CM-44 referencing the invoice. Pine now owes $900, not $1,100.
On Willow’s books, the simplified adjustment is debit Sales allowances $100 and credit Accounts receivable, Pine $100. The original invoice remains available and the credit is applied against it. Intuit distinguishes an immediate credit memo from a delayed credit for future use; those are not interchangeable timing instructions.
Seller-issued debit memo: increase the amount owed
Willow then documents $50 of additional completed work that was omitted from the original invoice and issues debit memo DM-44. The receivable rises from $900 to $950. Willow debits Accounts receivable, Pine $50 and credits Service revenue $50. This is an additional supported charge, not a reversal of the $100 allowance.
From Pine’s purchaser perspective, assuming the services are current-period expenses, the $100 credit reduces Accounts payable and service expense; the $50 extra charge increases service expense and Accounts payable. Inventory, asset purchases, taxes and prior-period errors can need different offsets, so these entries are deliberately limited to the stated facts.
Buyer debit notes and vendor credits need their own context
A buyer may use a debit note to request a supplier adjustment, such as a credit for returned goods. That label does not mean the buyer has received cash or that the seller has accepted the claim. Check the document’s wording, contract, return evidence and any vendor credit before treating the liability as reduced.
Do not apply a seller’s increase-in-receivable rule to every document called a debit note. Preserve who issued it, who owes whom, the linked invoice, approval status, tax treatment and whether payment has occurred. An approved credit after payment can create a refund or a credit for later use, rather than an unpaid invoice reduction.
Separate direction from accounting classification
For this guide’s bank-data convention, money in is positive and money out is negative. For the customer balance, an extra seller charge is positive and a seller credit is negative. These conventions describe different balances. Import software may expect positive values in separate debit and credit columns instead.
Fulla’s statement exports can help you review a bank fee or interest row against its PDF. They do not process invoices, issue credit memos or decide the revenue, tax or expense treatment of an adjustment. Keep invoice and bank evidence linked, but do not confuse them.

Questions about this guide
Does a credit memo always mean a cash refund?
No. A seller credit memo can reduce an unpaid receivable or create credit for later use. A refund is a separate cash movement, and the record should show how the credit was settled.
Why does a bank debit reduce cash when accounting debits increase Cash?
The bank is debiting its deposit liability to you. Your business records the reduction as a credit to its cash asset. The two records describe opposite sides of the same relationship.
