Businesses sometimes need to adjust an Invoice after it has been issued.
For example:
- A customer returns goods.
- Products are damaged.
- The original price was incorrect.
- An additional discount is granted.
- The invoiced quantity was incorrect.
- Additional charges need to be recorded.
- A transaction needs to be partially corrected.
In these situations, businesses may use a Credit Note or Debit Note.
Both are adjustment documents, but they serve different purposes.
Simply put:
A Credit Note generally reduces the amount previously invoiced.
A Debit Note generally increases the amount payable or records a specific adjustment, depending on the business context.
Understanding the difference is important for Sales, Finance, Accounting, Procurement, and Customer Service teams.
What Is a Credit Note?
A Credit Note is a document used to reduce part or all of the amount previously invoiced.
It may be issued when:
- Goods are returned.
- Products are damaged.
- The customer was overcharged.
- A quantity was incorrect.
- An additional discount is granted.
- Part of a transaction is cancelled.
- A pricing correction is required.
Simple example
A customer purchases:
10 units × IDR 1,000,000 = IDR 10,000,000
The customer later returns:
2 units
Adjustment:
2 × IDR 1,000,000 = IDR 2,000,000
The seller may issue a:
Credit Note = IDR 2,000,000
What Is the Purpose of a Credit Note?
1. Reduce the Invoice Amount
Example:
Original Invoice: IDR 20,000,000
Credit Note: IDR 3,000,000
Adjusted Amount: IDR 17,000,000
2. Record Product Returns
When customers return goods, a Credit Note can document the corresponding financial adjustment.
3. Correct Pricing
If an Invoice contains an incorrect price, a Credit Note can be used to adjust the amount.
4. Record Additional Discounts
If an additional discount is granted after the Invoice was issued, a Credit Note may be used to document the adjustment.
5. Reverse Part of a Charge
When part of a transaction is cancelled, the related amount can be adjusted through a Credit Note.
What Is a Debit Note?
A Debit Note is a document used to record an additional adjustment to a transaction, which may increase the amount payable or represent a specific claim or adjustment depending on the business context.
It may be used for:
- Additional charges
- Underbilling
- Shipping adjustments
- Additional services
- Administrative fees
- Price adjustments
- Other transaction corrections
The exact meaning and accounting treatment of a Debit Note can vary depending on the transaction and the perspective of the issuing party.
What Is the Purpose of a Debit Note?
1. Increase the Amount Payable
Example:
Original Invoice: IDR 10,000,000
Additional charge:
IDR 500,000
Debit Note:
IDR 500,000
Adjusted amount:
IDR 10,500,000
2. Correct Underbilling
Suppose the correct transaction value is:
IDR 15,000,000
But the original Invoice was:
IDR 14,000,000
Difference:
IDR 1,000,000
A Debit Note may be used to document the additional adjustment.
3. Record Additional Charges
Examples include:
- Shipping surcharge
- Handling fees
- Administrative fees
- Additional services
- Price adjustments

Suppose:
10 laptops × IDR 10,000,000
Original Invoice:
IDR 100,000,000
The customer returns two damaged laptops.
Returned value:
2 × IDR 10,000,000 = IDR 20,000,000
Credit Note:
IDR 20,000,000
Adjusted transaction value:
IDR 80,000,000
Debit Note Example
Original Invoice:
IDR 100,000,000
Additional shipping cost:
IDR 5,000,000
Debit Note:
IDR 5,000,000
Adjusted amount:

The exact accounting treatment should follow the company's accounting policy and applicable requirements.

IDR 5,000,000
Credit Note:
IDR 5,000,000
Adjusted amount:

Debit Note for Additional Charges

Example:
Original Invoice:
IDR 50,000,000
Additional charge:
IDR 2,500,000
Debit Note:
IDR 2,500,000
Adjusted amount:
IDR 52,500,000
Does a Credit Note Cancel an Invoice?
Not necessarily.
A Credit Note usually reduces part or all of an existing Invoice.
Example:
Invoice INV-001 = IDR 100,000,000
Credit Note CN-001 = IDR 20,000,000
Adjusted balance = IDR 80,000,000
The original Invoice remains part of the transaction history, while the Credit Note records the adjustment.
Does a Debit Note Create a New Invoice?
Not necessarily.
A Debit Note can be used as an adjustment document related to an existing Invoice.
For example:
Invoice = IDR 100,000,000
Debit Note = IDR 5,000,000
Adjusted amount = IDR 105,000,000
The exact workflow depends on the company's invoicing and accounting procedures.
