From a Purchase to a Payment
A customer taps a card, and the terminal displays “approved.” That message is useful, but it does not by itself show that the merchant has received funds. A retail payment typically involves several distinct actions: an initial check and approval, the submission and processing of transaction details, and the eventual movement of funds between financial institutions. These stages can happen at different times.
This tutorial traces a hypothetical card purchase through those stages, then compares it with a bank-to-bank electronic payment. The exact routing, timing, fees, and account entries depend on the payment method and the agreements among participants. The central task is to identify who communicates, who owes or receives funds, and what has—or has not—happened at each stage. This material is aligned with the SOA VEE Economics (Validation by Educational Experience) syllabus.
The Participants and Their Roles
For a common card purchase, the customer presents a card or a digital wallet that uses a card. The merchant accepts the payment and submits transaction information, often through a payment processor. The merchant’s financial institution is commonly called the acquirer; it provides or supports the merchant’s card-acceptance service. The issuer is the financial institution that issued the customer’s card. A payment network routes messages between participants and supplies rules or services for processing transactions. A processor may handle messages or records for a merchant, acquirer, or issuer, but it is not necessarily a bank or the institution that ultimately transfers funds.
During authorization, the issuer may check details such as whether the account or credit line can support the requested transaction and whether the request meets applicable controls. An approval allows the transaction to proceed under the relevant rules; it is not the same as a completed transfer to the merchant. For a debit card, an approval may lead to a hold on available funds or a pending account entry. For a credit card, the transaction may increase the customer’s amount owed to the issuer. The precise customer-facing entry depends on the issuer and payment method.
After the purchase, the merchant submits transaction details for clearing. Those details may include the final amount and transaction identifiers. The parties use processed records to determine the amounts due. At settlement, funds move between financial institutions under the arrangement used by the payment system. A merchant may see a credit in its account before or after settlement between institutions, depending on its agreement with the acquirer. A later refund or dispute can also affect the final economic outcome.
| Stage | What happens | What the stage does not establish by itself |
|---|---|---|
| Authorization | A request is checked and approved or declined under the payment method’s rules. | That the merchant has received settled funds. |
| Clearing | Transaction records are submitted and processed to establish amounts due. | That the related transfer of funds is complete. |
| Settlement | Funds are transferred between financial institutions according to the applicable arrangement. | That no later refund, reversal, or dispute can occur. |
Worked Examples: Following the Stages
Worked Example: A Card Purchase and the Merchant’s Net Receipt
Method: trace each stage separately, then apply the stated merchant fee. A customer uses a credit card to buy a hypothetical office chair for $120.00. The issuer approves the $120.00 authorization. The merchant later submits a $120.00 transaction for clearing. Assume, solely for this example, that the merchant’s agreement charges a fee of 2.6% of the transaction plus $0.10, that this fee is deducted from the amount paid to the merchant, and that there are no other adjustments. What does the customer owe the issuer for this purchase, and what is the merchant’s net receipt under these assumptions?
1. Authorization. The customer’s card request is for $120.00, and the issuer approves it. This permits the purchase to proceed; it is not evidence that the merchant has already received $120.00 in settlement.
2. Clearing. The merchant submits the final transaction amount of $120.00. The clearing record therefore reflects a $120.00 purchase.
3. Customer’s amount. The purchase adds $120.00 to the customer’s amount owed to the issuer, subject to the card agreement and any later adjustments. It does not mean the customer made a $120.00 deposit transfer at the register.
4. Merchant fee. The percentage component is \(0.026 \times \$120.00 = \$3.12\). Adding the stated fixed component gives \(\$3.12 + \$0.10 = \$3.22\).
5. Merchant’s net receipt. Under the assumed fee arrangement, \(\$120.00 - \$3.22 = \$116.78\). Thus the transaction is recorded for a gross purchase amount of $120.00, while the merchant receives $116.78 after this particular fee. The fee and net amount depend on the hypothetical agreement, not on a universal card fee.
Check. The assumed gross amount is accounted for by the merchant’s net receipt and fee: \(\$116.78 + \$3.22 = \$120.00\). A common mistake is to treat authorization as proof of merchant receipt; the stages above show why that conclusion does not follow.
Worked Example: A Debit Card Purchase with a Final Amount Different from the Initial Request
Method: distinguish the initial authorization amount from the final cleared amount. At a hypothetical café, a customer uses a debit card for a meal costing $38.50 and leaves a $4.50 tip. The initial $38.50 request is approved. Assume the payment method permits the final $43.00 amount to be submitted for clearing, and that the customer’s available balance before authorization is $210.00. The merchant’s hypothetical agreement charges 1.5% of the final amount plus $0.15 per transaction. The fee is rounded to the nearest cent, with half a cent rounded up; no other adjustments apply. Find the amount initially left available after the authorization, the amount left after the final debit, and the merchant’s net receipt.
1. Authorization hold. The initially approved amount is $38.50. The available balance after this hold is \(\$210.00 - \$38.50 = \$171.50\). This is the amount left available under the stated assumption while the initial authorization is pending; it is not necessarily the final posted debit.
2. Final clearing amount. The meal and tip total \(\$38.50 + \$4.50 = \$43.00\). Under the example’s assumption, the merchant submits $43.00 for clearing.
3. Customer’s final balance change. After a final debit of $43.00, the balance is \(\$210.00 - \$43.00 = \$167.00\). Compared with the initial authorization, the final amount is higher by \(\$43.00 - \$38.50 = \$4.50\).
4. Merchant fee. The percentage component is \(0.015 \times \$43.00 = \$0.645\), which rounds to $0.65. The total fee is \(\$0.65 + \$0.15 = \$0.80\).
5. Merchant’s net receipt. Under the stated agreement, \(\$43.00 - \$0.80 = \$42.20\). The gross cleared purchase is $43.00; the fee explains the difference between that amount and the merchant’s net receipt.
Check. The final balance is $167.00, and the merchant’s net plus fee is \(\$42.20 + \$0.80 = \$43.00\). A common mistake is to use the original $38.50 authorization as the final purchase amount, ignoring the tip in the cleared transaction.
Worked Example: An Electronic Bank-to-Bank Retail Payment
Method: trace the payment instruction through the customer’s bank and the merchant’s bank. A customer makes a hypothetical $86.00 online purchase using a bank-to-bank electronic payment service, not a card. Assume the customer’s bank verifies the payment instruction and available funds, the payment service confirms a completed transfer of $86.00 to the merchant’s bank, the merchant has no fee for this payment, and the customer pays a separate $0.25 service fee. The customer’s starting account balance is $310.00. Find the total reduction in the customer’s account and the amount credited to the merchant under these assumptions.
1. Instruction and check. The customer instructs the bank to pay $86.00. The bank verifies the instruction and, under the example’s assumptions, confirms that the payment can proceed.
2. Electronic transfer. The payment service carries the $86.00 instruction through the relevant payment arrangement. The example specifies that the transfer is confirmed as completed and the merchant’s bank credits the merchant with $86.00. Unlike the card examples, this scenario has no card issuer, card acquirer, or card-network authorization.
3. Customer’s total account reduction. The purchase amount and separate service fee total \(\$86.00 + \$0.25 = \$86.25\). The remaining customer balance is \(\$310.00 - \$86.25 = \$223.75\).
4. Merchant credit. Since the example assumes no merchant fee, the merchant is credited $86.00. The customer’s separate $0.25 fee is not part of the purchase amount paid to the merchant.
Check. The customer’s account decreases by $86.25, while the merchant receives $86.00; the $0.25 difference is the stated customer fee. Actual electronic payment services differ in how they validate, route, and confirm a transfer, so this sequence should not be assumed for every service.
Why the Stages Are Separate
Authorization and settlement answer different questions. Authorization is an early decision about whether a payment request may proceed. Clearing supplies the transaction record needed to establish the amount due. Settlement completes a transfer under the payment arrangement. A check at the first stage can be useful without answering the later questions: the final amount may differ from the authorized amount, and the participating institutions still need to process and settle the transaction.
The distinction can also be seen by reconciling a hypothetical card purchase. Let \(G\) be the final gross purchase amount, \(F\) the merchant fee under a specified contract, and \(N\) the merchant’s net receipt under an arrangement that deducts that fee. By definition of this assumed arrangement, \(N = G - F\). Rearranging gives \(G = N + F\): the gross transaction is divided between the merchant’s net receipt and the fee. This is an accounting explanation for the arithmetic in the examples, not a claim that every payment system charges or allocates fees in the same way.
In practice, a merchant’s account may be credited on a schedule set by its agreement, and settlement between financial institutions may occur on a different schedule. A customer’s pending entry, a merchant’s account credit, and settlement between institutions are therefore not interchangeable descriptions of the same event. Nor does settlement mean a transaction can never be adjusted later: refunds, reversals, and disputes may lead to subsequent payments or records.
The customer presents a card or submits an electronic payment instruction for a stated purchase.
For a card, authorization commonly involves a request routed to the issuer. Other electronic methods use their own checks and message flows.
For a card transaction, clearing processes the final transaction record and helps establish amounts due. A bank-to-bank method follows its own processing steps.
Funds move according to the payment arrangement. The timing of this transfer and the timing of customer or merchant account entries may differ.
Common Mistakes and Why the Distinction Matters
- Treating “approved” as “paid to the merchant.” Approval means the request passed an initial check under the applicable rules. It does not, by itself, establish that settlement is complete.
- Assuming the authorized amount must equal the cleared amount. A final amount can differ where the payment method and rules allow it. Use the final transaction record when tracing the cleared purchase.
- Confusing customer account entries with institutional settlement. A pending debit, an increased credit-card balance, or a merchant account credit is an account entry. It does not necessarily tell you exactly when funds moved between financial institutions.
- Assuming every digital wallet is a separate payment rail. A wallet may simply present a card or another underlying payment method. To trace the transaction, identify how the wallet is funded and which method actually processes the purchase.
- Applying one fee structure to all transactions. Fees vary by agreement and payment method. Calculate a fee only from the terms given, and distinguish the gross purchase from the merchant’s net receipt.
Tracing these stages matters because an approval message, a customer’s account record, and a merchant’s receipt describe different parts of a payment. Keeping the participants and amounts distinct makes it easier to interpret payment flows without assuming that every method follows the same route.
Check Your Understanding
For each hypothetical case, identify the relevant stage or calculate the requested amount. Read each stated assumption carefully.
- A customer’s card request for $64.00 is approved. The merchant has not yet submitted the transaction record. Which stage has occurred, and what has not yet been established? (Answer: Authorization has occurred; clearing of the transaction and settlement to the merchant have not been established.)
- A shop clears a $75.00 card purchase. Its hypothetical fee is 2% plus $0.20, deducted from the gross amount, with no other adjustments. Calculate the fee and merchant net. (Answer: Fee = \(0.02 \times \$75.00 + \$0.20 = \$1.70\); net = $73.30.)
- A debit-card authorization holds $29.00 against an initial available balance of $150.00. The final cleared purchase is $32.00. What is the available amount after the initial hold, and what is the balance after the final debit? (Answer: $121.00 after the hold; $118.00 after the final debit.)
- A hypothetical electronic bank-to-bank payment sends $92.00 to a merchant. The customer also pays a separate $0.30 fee, and the merchant pays no fee. What is the customer’s total account reduction, and what does the merchant receive? (Answer: Customer reduction = $92.30; merchant receives $92.00.)
- A merchant’s final cleared card purchase is $140.00. Under its hypothetical contract, the fee is 1.8% plus $0.12, deducted from the purchase amount. The issuer had initially approved $135.00, and there are no other adjustments. Calculate the fee and net receipt, and identify the amount used for that calculation. (Answer: Use the final cleared amount, $140.00; fee = \(0.018 \times \$140.00 + \$0.12 = \$2.64\); net receipt = $137.36.)
