The verdict in three sentences
The same mobile money payment does not have the same approval rate depending on which PSP processes it: one rail may sit at 91% where another hits 95% on the same operator. Smart routing sends each transaction to the PSP that succeeds best for that operator, at that moment. On moderate volume, gaining 2 to 4 approval points translates directly into recovered revenue, without spending a single cedi more on acquisition.
The operator-by-PSP matrix
The starting point is measuring, operator by operator, which PSP approves best. Here is a 2026 order-of-magnitude example (approval rates observed over a rolling month).
| Operator | PSP A | PSP B | Best rail |
|---|---|---|---|
| MTN Mobile Money | 94% | 91% | PSP A |
| Vodafone Cash | 89% | 95% | PSP B |
| AirtelTigo | 92% | 90% | PSP A |
| Visa/MC card | 93% | 88% | PSP A |
| Bank transfer | 90% | 93% | PSP B |
Without routing, you send everything to one PSP and inherit its weak spots. With routing, each operator goes to its best rail: the weighted average rises mechanically.
The routing rules that matter
A good routing policy isn't only about approval: it factors in cost, latency and real-time rail health.
| Rule | Trigger | Action | Target gain |
|---|---|---|---|
| Best-approval | Measured operator rate | Route to best PSP | +2 to 4 pts |
| Least-cost | Equal approval | Route to cheapest | -0.3 to 0.8% fees |
| Health-based | Errors > 8% over 5 min | Pull rail temporarily | Avoids burst losses |
| Latency-cap | Response > 12s | Switch to fast rail | Fewer cart drops |
| Weighted split | A/B test | Split 70/30 | Continuous measurement |
The key: these rules recompute continuously. A rail that's excellent on Monday can degrade on Friday; routing follows reality, not a frozen config.

Moving from 91% to 95% approval on a given volume means 4% more transactions completing. Here is the impact by processed revenue.
| Monthly processed revenue | +4 approval pts | Annual gain |
|---|---|---|
| NGN 3M | +NGN 120k/month | NGN 1.44M |
| NGN 9M | +NGN 360k/month | NGN 4.32M |
| NGN 24M | +NGN 960k/month | NGN 11.5M |
Mini case study
Kwame, who runs an online store in Accra, processes the equivalent of NGN 9M/month at an average approval rate of 91%. By enabling best-approval routing, MTN stays on its best PSP and Vodafone switches to the 95% rail. His average rate climbs to 94.5%, i.e. +3.5 points. That means ~NGN 315k/month of recovered sales, or ~NGN 3.78M/year, without a single cedi of extra acquisition. Routing simply handed him back money that was already leaking.
FAQ
How many approval points can you really gain? On real volume, 2 to 4 points are common between the worst and best rail per operator. The gap depends on each PSP's integration quality with each operator.
Does routing replace failover? No, they complement each other: routing picks the best rail up front; failover catches a transaction that fails anyway by retrying it on another rail.
Do you need high volume for it to pay off? From ~NGN 3M/month processed, a 3-point gain already yields ~NGN 1.44M/year, well above setup cost. Below that the effect is positive but less dramatic.
How do you measure per-operator rates? Log every attempt with operator, PSP and outcome, then compute a rolling rate over 7 to 30 days. That data feeds the routing rules.
Is multiplying PSPs risky? The real risk is reconciliation: you need a consolidated dashboard. Properly tooled, multi-PSP reduces single-vendor dependency.
