The verdict in three sentences
In Kampala in 2026, mobile money captures around 70 % of online payments, split between MTN MoMo and Airtel Money. Integrating each operator directly takes 4-8 weeks of development per rail plus ongoing maintenance; a gateway unifies MTN, Airtel and card in 3-5 days for a 1.4-2 % commission. The real question isn't "direct vs gateway" in the abstract, but at what volume direct integration pays off.
Direct integration vs gateway — 2026 comparison
| Criterion | Direct integration | Gateway (Flutterwave, Paystack, local) |
|---|---|---|
| Time to launch | 4-8 weeks/operator | 3-5 days |
| Per-transaction commission | Raw operator rate (~1-1.5 %) | 1.4-2 % |
| Operators covered out of the box | 1 | 3 to 6+ |
| Estimated annual maintenance | 3,000-8,000 USD | Included |
| Uptime | On you | 99.5 %+ contractual |
| Reconciliation | Manual per rail | Unified dashboard |
Total cost over 12 months — estimate
Simulation for a merchant collecting 40,000,000 UGX/month (480,000,000 UGX/year). 2026 estimate.
| Item | Direct (2 operators + card) | Gateway |
|---|---|---|
| Collection commission | ~1.2 % → 5,760,000 UGX | 1.6 % → 7,680,000 UGX |
| Initial development | 8,000,000-14,000,000 UGX | 1,000,000-2,400,000 UGX |
| Annual maintenance | 3,000,000-8,000,000 UGX | 0 (included) |
| Estimated year 1 total | ~16,800,000-27,800,000 UGX | ~8,600,000-10,000,000 UGX |
Direct integration only becomes competitive at very high volume, where the commission saving outweighs dev and maintenance cost.
What a gateway must cover
| Function | Essential | Why |
|---|---|---|
| MTN MoMo + Airtel Money | Yes | ~70 % of payments in Uganda |
| Card (Visa/Mastercard) | Yes | Diaspora and B2B |
| Confirmation webhooks | Yes | Order reliability |
| Refunds | Yes | Disputes and returns |
| Reconciliation dashboard | Yes | Accounting |
| Automatic payout | Nice to have | Cash flow |
Mini case study
David launches an electronics marketplace in Kampala. Direct MTN + Airtel + card quote: 12,000,000 UGX and 7 weeks. Choosing a gateway, he goes live in 4 days for 1,800,000 UGX of integration, 1.6 % commission. In his first year at 16,000,000 UGX/month volume, the gateway costs ~4,900,000 UGX all-in versus ~15,400,000 UGX direct: he keeps over 10,000,000 UGX for launch marketing.

FAQ
When does direct integration pay off?
Generally above tens of millions in stable monthly volume, when the commission gap (0.3-0.6 %) exceeds annual dev and maintenance cost. Below that, the gateway almost always wins.
Does a gateway slow down payments?
Not if its contractual uptime is 99.5 %+ and it handles operator timeouts with retry. Check the SLA and historical status before signing.
Can I switch gateways later?
Yes, if you isolate payment logic behind a unified interface in your code. That is exactly the architecture we build to avoid lock-in.
What happens if one operator goes down?
A good gateway routes the customer to another available rail (card or another wallet), protecting your conversion rate during the incident.
