The verdict in three sentences
Handing cash salaries or bonuses to dozens of staff wastes time, invites theft and leaves zero traceability. An MTN MoMo bulk disbursement pays everyone in minutes, for 0.5 to 1.2 % tiered fees and a cap of 5,000,000 per lot depending on KYC. The key choice: a CSV file (simple, monthly) or an API (real-time, automated) — always with dual validation before sending.
CSV vs API: which bulk disbursement channel?
A CSV file suits stable monthly payroll: prepare the file, upload it to the MoMo Business portal, approve it. The API suits frequent or variable flows (bonuses, referral commissions, refunds) that must go out automatically.
| Criterion | CSV file (portal) | API (integration) |
|---|---|---|
| Setup | Immediate | 2 to 4 weeks of dev |
| Ideal frequency | Monthly | Daily to weekly |
| Volume per lot | Up to 5 M | Up to 5 M (split batch) |
| Invalid-number handling | Manual (line reject) | Automatic (retry) |
| Dual validation | Yes (portal) | Yes (custom workflow) |
| Project cost | 0 | 800,000 to 2,000,000 (local ccy) |
Fee tiers and cost vs cash (2026 ballpark)
Disbursement fees are usually tiered by monthly volume. These are 2026 estimates to confirm with MTN Business.
| Monthly volume distributed | Estimated MoMo fee | Cost for 3 M | Equivalent cash cost (transport, security, time) |
|---|---|---|---|
| < 1 M | 1.2 % | 36,000 | 40,000 to 60,000 |
| 1 to 5 M | 0.9 % | 27,000 | 60,000 to 90,000 |
| 5 to 20 M | 0.7 % | 21,000 | 120,000+ |
| > 20 M | 0.5 % | 15,000 | Hard-to-quantify risk |
Cash looks "free" but costs in bank withdrawal, secure transport, counting time and loss risk. Beyond 20 beneficiaries, mobile money is almost always cheaper and far more traceable.

Mini case study
Ibrahim runs a cleaning SME in Kampala with 45 staff paid the equivalent of 85,000/month, a 3,825,000 payroll. He used to withdraw cash at the bank (fees + 2 h queue), count it, and distribute over two days. Now he uploads a 45-line CSV to the MoMo Business portal: paid in 8 minutes, 0.9 % fee equals 34,425, versus an estimated cash cost above 70,000 (secure transport + time). Bonus: each agent gets a confirmation SMS, which eliminated payroll disputes.
FAQ
What's the per-lot cap on MTN MoMo? In 2026, expect roughly 5,000,000 per lot depending on the business account's KYC tier. Above that you split into several batches, which is transparent to beneficiaries.
How do you handle invalid numbers? In CSV, the faulty line is rejected and fixed manually. In API, a retry mechanism isolates the line and replays only it, without blocking the other 44 payments.
Is mobile money really cheaper than cash? Beyond 20 beneficiaries, yes: 0.7 to 1.2 % visible fees versus hidden cash costs (transport, security, counting) that are often higher, plus theft risk.
What security against errors or fraud? Dual validation (preparer + approver), a per-beneficiary cap, and a timestamped ledger. No transfer leaves without a second signature in a well-designed workflow.
How long to integrate the API? Budget 2 to 4 weeks of development and 800,000 to 2,000,000 depending on needs (validation workflow, reconciliation, notifications). CSV, by contrast, is usable immediately.
