The verdict in three sentences
Reconciliation is not a minor bookkeeping chore: it is the point where your cash quietly leaks between the order, the webhook and the operator payout. On a typical mobile money flow, 2 to 5% of lines fail to match on the first pass because of fees deducted at source, partial payouts and XOF/NGN rounding. With an automated 4-step loop, an SME can close its month in under 2 days instead of a week, and catch every orphan unit.
The 4-step reconciliation loop
The principle: every order must be tracked all the way to the money actually credited to your account, not just to the "payment confirmed" shown to the customer.
| Step | What you match | Source of truth | Typical anomaly |
|---|---|---|---|
| 1. Capture ref | Order ↔ transaction reference | Store database | Missing or duplicate ref |
| 2. Match webhook | Ref ↔ operator notification | Signed webhook | Webhook received, no order found |
| 3. Match payout | Webhook ↔ funds received | Operator statement (T+1/T+7) | Fees deducted, net ≠ gross |
| 4. Flag orphans | Unmatched lines | Exception report | Payment with no order, or vice versa |
Steps 1 and 2 run in real time; steps 3 and 4 run nightly and feed an exception report the bookkeeper handles at month end.
Fees, payouts and rounding: the real gap
The amount the customer pays is almost never the amount you receive. Fees are often taken at source, and payouts are batched into T+1 or T+7 lots. Here are the 2026 orders of magnitude to budget for.
| Item | 2026 order of magnitude | Reconciliation impact |
|---|---|---|
| Mobile money merchant fee | 1.0 to 1.8% of amount | Net credited < gross order |
| Payout batching | T+1 (daily) to T+7 (weekly) | Cash vs order timing gap |
| XOF rounding | To the franc, no cents | 1-5 FCFA gaps per line |
| Partial payout | 1 transfer for N orders | Hard to split without ref |
| Unmatched lines | 2 to 5% of volume | Target < 1% after automation |
| Monthly close time | 5-7 days manual → < 2 days | Better cash visibility |
The golden rule: store the gross amount, the fees, and the net separately the moment the webhook lands. Matching a net against a gross without knowing the fee is the number one cause of orphan lines.

Mini case study
Awa, who runs a cosmetics store in Dakar, collects 3,200,000 FCFA across 480 orders in January. Without reconciliation, she sees a total payout of 3,142,000 FCFA and suspects theft. Applying the loop: merchant fee 1.5% = 48,000 FCFA, plus 12,000 FCFA from 4 refunded orders not deducted from her records. That leaves 200 FCFA of rounding across 480 lines — everything is explained. Close time: 1.5 days instead of 6. The next month she catches 2 orphan payments (35,000 FCFA) that were orders never fulfilled due to a missed notification.
FAQ
Why do my payouts never match my total sales? Because merchant fees (1 to 1.8% in 2026) are taken at source, and refunds and partial payouts shift the batches. You must reconcile against expected net, not gross sold.
How many unmatched lines is normal? Without tooling, 2 to 5% of volume is common. With an automated loop and gross/fee/net storage, you target under 1% of lines in exception.
T+1 or T+7, which batching should I choose? T+1 (daily payout) hugely simplifies reconciliation and cash flow but sometimes costs more. T+7 batches and lowers fees but complicates splitting.
Can I close a month in under 2 days? Yes, if steps 1-2 are real time and the exception report only contains true anomalies. A realistic target is 1 to 2 days versus 5 to 7 manually.
What do I do with an orphan payment that has no order? Freeze it in a suspense account, search the reference in the logs, and contact the customer via WhatsApp. Never fulfill or refund it until it is matched.
