The verdict in three sentences
Without automation, a merchant leaves in 2026 up to 8 % of orphaned payments — collected but never linked to an order — which distorts accounting and VAT. Reconciliation via webhooks, transaction references and CSV export brings that rate near zero and saves 3 to 5 h/week. The cost of an accounting connector (15,000 to 40,000 FCFA/month) is largely repaid by time saved and errors avoided.
Automatic reconciliation method
The principle: each payment carries a unique reference tied to an order, confirmed in real time by a webhook. Here are the layers.
| Step | Mechanism | Reliability | Effort |
|---|---|---|---|
| Unique reference | Order ID inside the payment | High | Initial config |
| Real-time webhook | Operator notification -> server | High | Dev integration |
| Daily CSV export | Operator statement | Medium | Automatable |
| Accounting connector | Sync to software | High | Subscription |
| Manual check | Discrepancy review | Safety net | Weekly |
The webhook + unique reference combination covers the vast majority of cases; the CSV export and weekly check catch the exceptions.
Cost and gain of automated reconciliation
2026 order-of-magnitude comparison between fully manual tracking and automated reconciliation, for a shop with 400 orders/month.
| Item | Manual | Automated |
|---|---|---|
| Time/week | 4 to 5 h | 30 min |
| Orphaned payments | up to 8 % | < 1 % |
| Tool cost/month | 0 FCFA | 15,000 to 40,000 FCFA |
| VAT error risk | High | Low |
| Monthly close time | 3 to 5 days | 1 day |
At 400 orders/month, moving from 8 % to under 1 % orphans means reconciling more than 28 payments a month previously lost in the wild.
Mini case study
Sokhna, who runs an online ready-to-wear shop in Thies, handled her Wave and OM payments by hand: 4 h/week and about 25 unlinked payments/month out of 400 orders. By installing a webhook with an order reference and a 25,000 FCFA/month accounting connector, she dropped to 30 min/week and fewer than 4 orphans/month. Time saved valued at about 60,000 FCFA/month, for a tool cost of 25,000 FCFA: immediate return on investment, not counting secured VAT.

FAQ
What is an orphaned payment?
A mobile money collection received but not linked to a specific order. Without reconciliation it can represent up to 8 % of volume and distorts declared revenue.
Is a webhook essential?
It is the most reliable way to confirm a payment in real time and link it to the right order. Without it you depend on slower CSV exports prone to discrepancies.
How much does an accounting connector cost?
From 15,000 to 40,000 FCFA/month depending on software and volume. The 3 to 5 h/week gain generally repays the subscription easily.
Does reconciliation help with VAT?
Yes: a clean, linked payment base makes computing collected VAT easier and reduces error risk during filings.
Can Wave and Orange Money be reconciled together?
Yes, by normalizing references and centralizing both operators' webhooks into a single order ledger.
