If expense descriptions and repayment records are kept separately, it is difficult to verify if the two sets of data match. You can identify discrepancies by assigning the same transaction number and organizing the data so that the base amount, actual amount received, and payment schedule follow a sequence. This is a method to transition from the stage of reading descriptions to the stage of creating records.
Linking two data items to one transaction
Save the cost guide along with the verification date and record the corresponding data number on the payment slip. If the guide changes, link the new version but do not delete the past data. Once the actual bill is calculated, compare it with the estimated amount and leave only the differences as additional questions.
The reason for writing receipts and payments in different columns
Record the base amount for the transaction on the first line of the calculation sheet, the actual amount received after deductions on the second line, and the amount to be paid later on the third line. Although these three amounts may look similar, they serve different roles. Checking only the amount received leads to missing future payments, while checking only the principal amount to be paid leads to missing the initial deduction. If there are any separate expenses, first check which amount they are already included in to avoid adding them twice.
For the purpose of explaining the calculation, assuming a base amount of 1 million won, a received amount of 900,000 won, and a total subsequent payment of 1.03 million won, the initial difference is 100,000 won, and the difference between the total payment and received amount is 130,000 won. This difference cannot be directly referred to as the annual interest rate because the period and payment timing are not reflected. In the comparison table, amounts in won and dates are listed together, and unconfirmed fees are indicated as ‘Unconfirmed’ instead of 0 won.
Check before interpreting the difference
If the initial total differs from the actual bill, check for omitted costs, reflection timing, and recording errors. You must distinguish between the fact that a difference exists and its cause. Do not assume it is a specific cost until the cause is identified; instead, mark it as an inquiry.
An example connecting guidance to actual billing
Assigning data numbers to the same transaction makes it easy to identify the basis for calculation. If the guidance differs from the actual bill, do not simply note the difference; ask which item caused it. Distinguish pre-verification estimates from the final classification, and add the verification date to new guidance.

Frequently Asked Questions
Why are cost data and payment slips linked?
This is to compare the instructions and results of the same transaction. Without a connection, it is difficult to determine which explanation was used as the basis for the calculation. Attaching the transaction number and verification date allows you to quickly narrow down the questions to ask if there is a discrepancy in the actual bill.
