The verdict in three sentences
Settlement reconciliation for mobile money means linking every line of the MTN MoMo settlement file to a sales invoice and an accounting entry. In Accra in 2026, the difficulty comes from fees withheld at source (the amount credited is never the amount invoiced) and from VAT on commissions to isolate. A settlement-to-invoice mapping table and a standard entry template remove 90 % of data-entry errors.
The T+1 settlement file
MTN MoMo provides a settlement file the next day (T+1). Each line represents a transaction with the gross, the fees withheld and the net credited. Reconciliation crosses this file with your invoices.
| Settlement field | Accounting role |
|---|---|
| Transaction reference | Matching key with the invoice |
| Gross amount | Revenue invoiced |
| Operator fees withheld | Expense (bank charges) |
| Net amount credited | Actual cash in bank |
| Value date | Date of the cash entry |
Without this crossing, the SME books the net and loses track of the gross and fees, distorting VAT and margin.
Mapping table on a sample transaction
For a sale of GH₵ 500 with ~1.5 % MoMo fees (2026 order of magnitude):
| Item | Amount (GH₵) | Ledger account |
|---|---|---|
| Gross sale ex-VAT | 423.73 | Sales |
| VAT collected | 76.27 | VAT payable |
| Total invoiced incl. VAT | 500.00 | Trade receivables |
| MoMo fees withheld | 7.50 | Bank charges |
| Net credited | 492.50 | Bank / MoMo |
The ex-VAT/VAT split assumes a representative rate; adapt to the SME's actual regime.
Accounting entry template
The cash entry must reflect both the net received and the fees borne:
| Account | Description | Debit (GH₵) | Credit (GH₵) |
|---|---|---|---|
| Bank MoMo | Net credited | 492.50 | — |
| Bank charges | MoMo fees | 7.50 | — |
| Trade receivables | Invoice settlement | — | 500.00 |
The combined debit (492.50 + 7.50) equals the receivables credit of 500.00, clearing the invoice with no discrepancy.

Mini case study
Gifty keeps the books of a distribution SME in Accra: 1,200 MoMo transactions/month, average basket GH₵ 350, i.e. GH₵ 420,000 gross. At 1.5 % fees, she bears GH₵ 6,300/month in bank charges to isolate. Without automated reconciliation, these fees were buried in the net and never correctly deducted as an expense — a real tax loss. T+1 reconciliation surfaces them line by line and makes the filing reliable.
FAQ
Why does the amount credited differ from the amount invoiced?
MTN MoMo withholds its fees at source (~1.5 %). The net credited is therefore lower than the invoiced total; the difference is a bank-charge expense to record.
How do you treat VAT on the operator commission?
The MoMo commission may include deductible VAT. Isolate it on a dedicated account to reclaim it, rather than leaving it as a gross expense.
Is the T+1 file enough for an audit?
Yes, keep each timestamped settlement file; it is the supporting document linking the bank cash-in to the invoice, meeting audit requirements.
What do you do with a settlement line without an invoice?
It is an orphan transaction: a refund, a test or a double payment. Flag it and regularize before the monthly close.
Can the whole reconciliation be automated?
Largely: importing the T+1 file and joining by reference matches 98 %+ of lines automatically, leaving only exceptions to handle.
