Also called: Adjustment Transaction, Payment Adjustment, Settlement Adjustment
What an adjustment is
In payment processing, an adjustment is a change made to a transaction amount or account balance to address a discrepancy. An acquirer or processor can use adjustments to address duplicate charges, processing disputes and other errors. The entry can add money to or subtract money from your settlement balance.
The term covers different actions, so it does not identify one standard fee or one universal process. In a card checkout flow that starts with a pre-authorization, an adjustment can update the approved amount to match the final purchase. That adjustment is not the final charge: a separate capture completes the payment.
An adjustment label tells you money changed, not why it changed or whether the amount is right.
What it means for your costs
An adjustment is not automatically a processing fee. It could correct an amount, account for a refund, or record a disputed transaction against a later settlement. The label by itself does not establish who initiated it or whether the amount is correct.
For example, if a $100 sale is recorded but your settlement includes a $4 debit labeled as an adjustment, the $4 is a reduction in funds received, not proof of a $4 adjustment fee. Treat that example as illustrative. Find the transaction, stated reason and supporting detail before classifying it in your books.
A settlement adjustment
| Sale recorded | $100 (illustrative) |
|---|---|
| Adjustment debit | $4 (illustrative) |
| Amount before other activity | $96 (illustrative) |
Illustrative only. The adjustment reason must be verified before you record it as a fee or correction.
How to investigate one
Start with the affected sale and compare its original amount with the payment and settlement records. Check for a related refund, duplicate transaction, correction or dispute. A disputed payment can affect a later settlement, so match the adjustment to the original transaction rather than treating it as a new sale.
Keep the original transaction ID, adjustment amount, date and explanation together. If the entry has no transaction reference or reason, your books cannot show what changed. That makes it harder to spot duplicate deductions, correct an accounting error or explain a mismatch between your processor report and bank deposit.
What you can actually change
- Match the transaction. Find the original sale using its transaction ID, amount and date. Compare the sale, adjustment and settlement records.
- Get the reason. Record whether the entry relates to a correction, duplicate charge, refund or dispute. Do not classify an unexplained adjustment as a processing fee.
- Check repeat entries. Compare adjustments across settlement periods for repeated amounts or duplicate references. Keep the supporting records with your reconciliation.
Frequently asked questions
Is an adjustment the same as a processing fee?
No. An adjustment is a change to a transaction amount or account balance, and the label alone does not establish that it is a fee. Match the entry to its reason and supporting transaction before recording it as a processing cost.
Can an adjustment add money to my settlement?
Yes. An adjustment can increase or decrease the balance, depending on what is being corrected. Check the entry’s debit or credit direction, amount and transaction reference against your settlement records.
How do I dispute an unexplained adjustment?
Gather the adjustment date and amount, the related transaction ID and your settlement detail. Use those records to request an explanation and correction for the specific entry, rather than relying on the adjustment label alone.
