The verdict in three sentences
An aggregator does not replace operator fees, it stacks a commission on top: expect ~0.5 % MTN collection plus 0.5–1 % aggregator. In return you get one API for MTN MoMo and Airtel, a unified dashboard and automated payouts that save real engineering time. The break-even is simple: an aggregator earns its markup as long as the development and reconciliation time it saves outweighs the added commission.
Stacked operator + aggregator fees in 2026
2026 order of magnitude for merchant collection in Uganda; exact rates depend on contract.
| Setup | Aggregator fee | + Operator fee | Total collection cost |
|---|---|---|---|
| Aggregator A | ~1.0 % | ~0.5 % | ~1.5 % |
| Aggregator B | ~0.5 %–1 % | ~0.5 % | ~1.0 %–1.5 % |
| Disbursement | fixed UGX 500–1,000 | per payout | added |
| Direct integration | 0 % aggregator | ~0.5 % | ~0.5 % (dev on you) |
On UGX 400,000 collected, an aggregator costs UGX 6,000–10,000 while a direct integration costs about UGX 2,000 plus disbursement. The gap is the price of technical simplicity.
Aggregator break-even
| Monthly volume | Aggregator markup (~1 %) | Equivalent dev days saved | Verdict |
|---|---|---|---|
| 2,000,000 | 20,000 | < 0.5 day | Aggregator wins |
| 8,000,000 | 80,000 | ~1 day | Neutral |
| 20,000,000 | 200,000 | ~2 days | Compare |
| 80,000,000 | 800,000 | ~1 dev month / yr | Direct integration wins |
Below UGX 8,000,000/month the aggregator is almost always worth it: the markup stays under the cost of building and maintaining a direct integration. Above UGX 20,000,000/month, a direct MTN MoMo integration starts paying for itself because UGX 200,000/month quickly funds dedicated development.
Mini case study
Amina, who runs an online store in Kampala, collects UGX 16,000,000/month. Through an aggregator at ~1.5 % all-in, she pays UGX 240,000/month in fees. Moving to a direct MTN MoMo + Airtel integration (~0.5–0.7 %) once her volume stabilised would drop this to about UGX 100,000/month, saving UGX 140,000/month. But the initial build costs about UGX 2,500,000, so the payback lands near 18 months and only makes sense at her current volume level.

No, but it adds 0.5–1 % on top of the ~0.5 % operator fee, taking the total to 1–1.5 %. In exchange you connect MTN and Airtel through one API.
When does a direct integration pay off?
Above UGX 20,000,000/month, the aggregator markup (UGX 200,000) quickly funds dedicated development. Below UGX 8,000,000, the aggregator stays cheaper overall.
How much does MTN MoMo collection really cost?
About 0.5 % on collection plus UGX 500–1,000 fixed per disbursement. That fixed payout fee hurts merchants who withdraw in small, frequent batches.
How much does UGX 400,000 collected cost via aggregator?
Between UGX 6,000 and 10,000 all-in, versus about UGX 2,000 on a direct integration. The gap pays for simplicity and time saved.
Is bank payout included?
Rarely in full: most aggregators bill disbursement separately. Check this line, as it can add 0.5–1 % on withdrawals.
