Clearing and settlement
Clearing decides who owes whom. Settlement moves the money. They are a day or so apart, and neither of them puts anything in your bank account. That is funding, which comes later still.
Clearing
Once the batch closes, the acquirer sends clearing records to the network. The network works out which interchange category each transaction falls into, calculates the fees, and posts the amounts to the issuer and the acquirer.
This is the moment a transaction's price is finally set, and it is set using decisions made much earlier: whether the card was present, whether authentication ran, how long capture took, whether the industry-specific fields were filled in properly.
Downgrades happen here. A transaction that qualified for a good category at authorization can land in a worse one at clearing because it was captured late or arrived with data missing. Nobody tells you at the time. It shows up as a line on a statement weeks later, which is why interchange optimisation is a reporting exercise rather than something you can fix in real time.
Settlement
The network works out each member's net position and moves funds between issuer and acquirer settlement accounts, normally on the next banking day.
Two properties matter. Settlement is net, not gross: sales, refunds and chargebacks all offset each other, so no settlement figure will ever match a single transaction. And it runs on banking days, so a Friday evening batch and a Monday morning batch can settle together.
Three fees people call one fee
| Fee | Paid to | Set by | Varies with |
|---|---|---|---|
| Interchange | Issuer | Network schedule | Card type, channel, data quality |
| Assessments | Network | Network | Volume and transaction count |
| Processor markup | Acquirer, PSP, or facilitator | Your contract | What you negotiated |
Only the third is negotiable with your provider. When someone offers to "reduce your interchange," what is actually on the table is either qualifying for better categories through better data, or cutting the markup.
Pricing models differ mostly in how much of this you get to see. Interchange-plus itemises all three. Blended or flat-rate charges one percentage whatever the card, which is simpler and hides which of your transactions are expensive. Tiered pricing sorts transactions into buckets the provider defines, so the tier definitions matter far more than the headline rate.
Reconciliation
Settlement figures do not tie to order figures without work. A settlement amount is net of refunds and chargebacks, possibly net of fees, aggregated across a batch, and dated by batch close rather than by purchase.
Match at the largest grain first.
- Match the bank deposit to the funding record.
- Match the funding record to the batch.
- Match the batch to individual transactions.
Do not try to find an order total inside a bank deposit.
