Keeping Records and Reconciling Digital Payments

Build a simple daily record that separates sales, expenses, fees and movements between cash and wallet.

Part 9 of 10 | Mobile Money and Digital Payments Safety

Learning goals

You will record a small set of fictional transactions, calculate an expected closing wallet balance and compare it with a statement. You will distinguish business income from moving your own money and decide what information to keep privately for reconciliation and support.

Before you begin

Allow an hour with paper or a basic spreadsheet and a calculator. Use the invented amounts below only. This lesson teaches a simple control routine, not a full accounting or tax system. It gives no Gambian statutory retention period, tax rate or filing rule. Obtain current official advice for those separate obligations.

Record enough to explain the movement

Use columns for date, reference label, purpose, money in, money out, fee, status and related order. Add the place affected, such as cash or wallet. A reference helps distinguish two similar payments. The purpose explains whether the movement was a sale, purchase, personal withdrawal or transfer of your own funds.

Keep fees separate from the principal when the record allows it. Decide how your sheet calculates the total outflow so you do not count the fee twice. In this lesson, money out excludes the fee; total wallet outflow equals money out plus fee. Write that convention above the sheet and apply it consistently.

Work through a complete day

Start with a fictional wallet balance of GMD 1,000. A customer pays GMD 600 for goods, with no receiving fee assumed. Record GMD 600 in and label it a sale. You then pay a supplier GMD 350 with an additional fictional GMD 10 fee. Record money out 350 and fee 10, giving a total debit of GMD 360.

Next, you exchange GMD 200 of your own cash for GMD 200 wallet value, assuming no charge. Record the wallet credit and a matching cash reduction, labelled transfer of own funds. Finally, you withdraw GMD 100 cash with an additional fictional GMD 5 fee. Record wallet money out 100 and fee 5, and cash received 100.

Calculate and compare

Expected closing wallet value is 1,000 plus 600 minus 350 minus 10 plus 200 minus 100 minus 5, which equals GMD 1,335. The day's cash changes are minus 200 plus 100, a net reduction of GMD 100. The total illustrative fees are GMD 15. None of these figures is a current provider tariff.

Now compare the expected GMD 1,335 with the provider's closing record for the same period. Matching totals are useful, but inspect individual entries too: two errors can cancel each other numerically. Check references and statuses so a pending transaction is not accidentally treated as a settled one. Keep an unresolved item on a separate follow-up list rather than forcing the sheet to match.

Investigate differences without hiding them

Suppose the recorded closing wallet balance is GMD 1,325. The difference from your expectation is GMD 10. Check for an omitted charge, duplicate entry, incorrect amount or timing difference. These are possibilities to investigate, not conclusions. Do not insert an unexplained expense just to remove the discrepancy.

Use a note such as GMD 10 difference under review, with the date and next action. If a provider confirms an additional debit, enter it with the actual reference and explanation. If the provider record is corrected instead, document the correction. A transparent unresolved item is more useful than a tidy but inaccurate balance.

Keep privacy and business control together

Record only the customer information needed to match the payment and order. Do not put PINs, one-time codes or full identity documents in the ledger. Restrict access to statements and store any backup in a protected place. QMoney's privacy notice describes provider handling of customer information; it is not a rule granting every business unrestricted use of that information.

For a shared business, give staff the order information they need without sharing the owner's payment credentials. Where appropriate, ask the provider about suitable business accounts and supported access controls. Reconcile regularly and keep personal spending clearly labelled. Sales receipts are not automatically profit: stock costs, other expenses, timing and obligations matter beyond this simple wallet calculation.

Guided exercise

1. Draw the ledger columns and write the rule that the money-out column excludes fees. Enter the opening GMD 1,000 separately from the day's sales.

2. Enter all four events: sale, supplier payment, cash-in and cash-out. Add fictional reference labels and completed status for this exercise.

3. Calculate the expected closing wallet value, net cash change and total fees. Check the arithmetic with a partner or calculator.

4. Compare with a fictional statement showing GMD 1,325. Create an unresolved-item note and list two records you would inspect.

5. Write a privacy routine covering access, backup and redacted sharing with support. Do not choose a legal retention period without checking the applicable requirement.

Knowledge check

1. What is the expected closing wallet balance?

2. Is the GMD 200 cash-in a new sale?

3. Should an unexplained GMD 10 difference be hidden with a made-up expense?

Answer guide

1. GMD 1,335. Total fees are GMD 15 and cash falls by GMD 100.

2. No. It moves your own funds from cash to wallet.

3. No. Keep a clearly labelled unresolved item and investigate the actual entries.

Completion standard

Produce an accurate ledger, all three totals and an honest discrepancy note. Explain how the sheet avoids double-counting fees and own-fund transfers, and provide a privacy routine that contains no credentials.
