The verdict in three sentences
In 2026, picking a gateway on gut feel is expensive: a bad choice costs you lost margin and painful migrations. The right method is a 7-criteria weighted scorecard, scored 1 to 5, that turns an emotional call into an objective calculation. As a bonus, it sizes the integration effort in dev-days so there are no surprises.
The 7-criteria decision scorecard
Weight each criterion by your priorities, then score each gateway 1 to 5. The weighted total decides.
| Criterion | Suggested weight | What you assess |
|---|---|---|
| Rail coverage | 20% | Operators and markets supported |
| Fees | 20% | Rate + hidden costs |
| Settlement speed | 15% | T+1 to T+3 |
| API and docs | 15% | Quality, sandbox, webhooks |
| SLA / uptime | 10% | Guaranteed availability |
| Dispute tooling | 10% | Refund/chargeback tools |
| Local support | 10% | Responsiveness, language, timezone |
Quick read: coverage and fees weigh most, but a solid SLA and responsive support prevent losses far bigger than a few points of fees.
Worked example: Flutterwave vs Paystack vs DPO vs Pesapal
Scores 1 to 5 (2026 orders of magnitude, adjust to your case), multiplied by weight.
| Criterion (weight) | Flutterwave | Paystack | DPO | Pesapal |
|---|---|---|---|---|
| Coverage (20%) | 5 | 4 | 5 | 4 |
| Fees (20%) | 4 | 4 | 3 | 4 |
| Settlement (15%) | 4 | 5 | 3 | 4 |
| API / docs (15%) | 4 | 5 | 3 | 3 |
| SLA (10%) | 4 | 4 | 4 | 3 |
| Disputes (10%) | 3 | 4 | 4 | 3 |
| Local support (10%) | 4 | 4 | 4 | 4 |
| Weighted score /5 | 4.10 | 4.35 | 3.65 | 3.70 |
Consequence: none dominates everywhere. Paystack leads on API and settlement, Flutterwave on coverage, DPO and Pesapal on regional reach. Your weights pick the winner.
The integration effort to budget
| Scenario | Estimated effort | Note |
|---|---|---|
| One gateway, one market | 5 - 8 dev-days | Simplest case |
| One gateway, multi-market | 8 - 12 dev-days | Per-market config |
| Two gateways (redundancy) | 12 - 15 dev-days | Abstraction layer needed |
| Later migration | 5 - 10 dev-days | Cut by 3 with abstracted code |

Brian runs a restaurant in Nairobi launching online ordering and is torn between Flutterwave and Paystack. He weights API quality and settlement speed heavily (tight cash flow, in-house dev). With his custom weights, Paystack scores 4.4/5 and Flutterwave 4.1/5, so he picks Paystack. By isolating his payment logic behind a unified interface, he keeps the option to migrate in 5 dev-days instead of 15 if his needs change.
FAQ
How many criteria should I really score?
Seven is enough: coverage, fees, settlement, API, SLA, disputes and local support. Adding more dilutes the decision without improving it.
Is the cheapest gateway the best choice?
Rarely. A 3% gateway with a strong SLA and responsive support can cost you less than a 2.5% one that goes down on a peak sales day.
Should I plan for two gateways from the start?
Not necessarily, but isolate your payment logic behind a unified interface. That cuts a future migration from 15 to 5 dev-days and makes adding a backup gateway easy.
How do I set the weights?
Start from the suggested weights (coverage 20%, fees 20%...) then adjust to your reality: tight cash flow means more weight on settlement, international sales mean more weight on coverage.
How long does gateway integration take?
Budget 5 to 8 dev-days for a single gateway in one market, and 8 to 12 for multi-market. An abstraction layer adds a few days but protects your future migrations.
