The verdict in three sentences
There is no single best PSP: the right choice depends on your volume, your rail mix (card, transfer, USSD, mobile) and your international needs. Low volume favors a turnkey aggregator; high volume justifies a negotiated direct integration. This guide gives you 7 weighted criteria and switch thresholds to decide in 2026 without regret.
The PSP scorecard: 7 weighted criteria
Score each PSP from 1 to 5 on each criterion, multiply by the weight, sum up. The highest total wins for YOUR context.
| Criterion | Weight | What you assess |
|---|---|---|
| Fee per transaction | 25% | All-in effective rate |
| Rail coverage | 20% | Card, transfer, USSD, mobile |
| Settlement delay | 15% | T+1, T+2, T+3 |
| API quality / docs | 15% | SDK, sandbox, examples |
| Dashboard / reconciliation | 10% | Consolidation, exports |
| Technical support | 10% | Response time, language |
| Compliance / KYC | 5% | Registration, local rules |
A cheaper but poorly-covered PSP can lose more sales than it saves in fees: that's why coverage and fees together weigh 45%.
Volume switch thresholds
Volume decides the model. Here are 2026 indicative thresholds, average basket NGN 9,000.
| Monthly volume | Recommended model | Target fees | Why |
|---|---|---|---|
| < 300 sales | Turnkey aggregator | ~2% | No dev, fast go-live |
| 300 to 1,000 sales | Negotiated aggregator | ~1.7% | Volume enables talks |
| 1,000 to 3,000 sales | Hybrid (direct + aggregator) | ~1.4% | Optimize dominant rail |
| > 3,000 sales | Direct integration | ~1 to 1.3% | Every fee point counts |
Switching to direct is justified when annual fee savings clearly exceed the integration cost (NGN 2M to 4M one-off).
Total cost over 12 months
Put the models side by side for a store doing 1,500 sales/month (revenue NGN 13.5M/month).

| Item (over 12 months) | Aggregator (2%) | Hybrid (1.4%) | Direct (1.1%) |
|---|---|---|---|
| Annual fees | NGN 3.24M | NGN 2.27M | NGN 1.78M |
| Integration cost (one-off) | NGN 0 | ~NGN 1.5M | ~NGN 3M |
| Year 1 total | NGN 3.24M | NGN 3.77M | NGN 4.78M |
| Year 2 total | NGN 3.24M | NGN 2.27M | NGN 1.78M |
At this volume, the aggregator wins year 1, but hybrid and direct win from year 2. Below 1,000 sales, the aggregator stays the rational choice.
Mini case study
Emeka, who runs a high-tech store in Lagos, does 1,500 sales/month at NGN 9,000. On a 2% aggregator he pays NGN 270k/month in fees (NGN 3.24M/year). Switching to hybrid (dominant rail direct at 1%, card via aggregator), his effective rate drops to 1.4%, i.e. NGN 189k/month. He saves NGN 81k/month, or NGN 972k/year, against a ~NGN 1.5M integration cost amortized in ~19 months. From year 2, the saving is net.
FAQ
Which criterion weighs most? Fees (25%) and rail coverage (20%) make up 45% of the decision. A cheap but poorly-covered PSP loses sales it never recoups.
At what volume should I go direct? Beyond ~3,000 sales/month, fee savings (often > NGN 2M/year) exceed the direct integration cost. Between 1,000 and 3,000, hybrid is the best compromise.
How much does a direct integration cost? Expect NGN 2M to 4M one-off depending on the number of rails and checkout complexity. It's amortized by fee savings at high volume.
Is fast settlement worth a premium? If your cash flow is tight, T+1 rather than T+3 improves working capital; that can justify 0.2 to 0.3 extra fee points.
Can I change PSP later? Yes, but it requires re-testing webhooks and reconciliation. Designing your checkout with an abstraction layer makes a future switch painless.
