Mobile Money (MoMo) for business in Rwanda — the 2026 guide

Mobile Money is the dominant non-cash payment rail in Rwanda. MTN MoMo and Airtel Money between them reach virtually every adult Rwandan with a phone, in a country where consumer-card penetration is still low. For any consumer-facing business — restaurant, salon, retail shop, transport, pharmacy, education — accepting MoMo is essentially mandatory. This is the working 2026 guide for the business side of mobile money.

The two main MoMo networks

• MTN MoMo. Largest by user base. Best coverage outside Kigali. Default for most consumer transactions in Rwanda. Merchant product: MoMo Pay.
• Airtel Money. Second-largest. Strong in Kigali; presence across the country. Often slightly cheaper merchant fees. Merchant product: Airtel Money Merchant.

Both interoperate via the central switching infrastructure for transfers across networks. For receiving payments, accept both — pick a single merchant code per network and place both prominently at the till.

Personal wallet vs merchant wallet — the key distinction

Many small Rwandan businesses receive payments into the owner's personal MoMo wallet. This works for very small volumes but creates several problems as the business grows:

• Personal-wallet limits restrict daily and monthly throughput
• Mixing personal and business funds complicates accounting and creates RRA-audit exposure
• No EBM-integration support for personal wallets
• No multi-user access — only the SIM-holder can transact
• No formal merchant rate — personal-wallet receipts may attract higher fees
• No reconciliation tooling beyond the basic transaction history

Above a few million RWF per month in volume, every business should migrate to a proper merchant wallet.

Registering as a MoMo merchant

1. Visit an MTN or Airtel business centre with the business documents — RDB certificate, TIN, legal representative's ID, lease agreement (proof of business location)
2. Apply for a Merchant Code — a short numeric code customers dial to send payment
3. Pick the wallet structure — single till, multi-till, branch-level merchant codes
4. Receive the Merchant Code and credentials within 1-5 business days
5. Print the Merchant Code signage for till-side display — both networks supply templates
6. Set up settlement to the business bank account — direct transfer from the MoMo merchant wallet at agreed daily/weekly intervals

Merchant transaction fees

Both MTN and Airtel charge a small percentage on each merchant transaction. Approximate 2026 ranges (verify against current schedules):

• MTN MoMo Pay merchant transaction fee: ~1-1.5% per inbound transaction
• Airtel Money merchant transaction fee: ~1-1.5% per inbound transaction
• Settlement-to-bank fee: small per-transfer charge
• No fees on customer-side for paying to a merchant (this is what drives merchant adoption — customers see no cost)

For high-margin businesses (restaurants, salons, retail), the 1-1.5% is absorbed easily. For low-margin businesses (wholesale, fuel, large-ticket sales), MoMo is often offered alongside bank transfer to encourage the customer toward the cheaper rail.

Transaction limits

• Personal wallet daily limit: typically RWF 1-2 million depending on KYC tier
• Personal wallet monthly limit: typically RWF 10-20 million
• Merchant wallet daily limit: higher — typically RWF 5-10 million daily, with capacity for upgrade
• Merchant wallet monthly limit: typically RWF 50-100 million, upgradeable on request
• Per-transaction limit: typically RWF 500K-1M depending on tier

Integration with EBM

Once the customer has paid by MoMo, the business must still issue an EBM receipt. Two patterns:

1. Manual: Customer pays, MoMo confirms, cashier issues EBM receipt with payment method 'MoMo' selected. Most common for small businesses.
2. API-integrated: POS or accounting system receives the MoMo confirmation via API and auto-generates the EBM receipt. Becoming standard for medium and larger retailers. Most major POS providers in Rwanda support this.

Settlement to the bank

Funds in the MoMo merchant wallet are not in the business's bank account. They need to be settled across to the business bank account for accounting, salary payments, and tax-payment purposes. Settlement options:

• Daily auto-settlement — funds swept to the bank account each evening. Cleanest from an accounting standpoint.
• Weekly auto-settlement — useful for businesses with predictable weekly cash needs
• On-demand manual transfer — initiated by the business as needed. More flexible but requires manual workflow
• Bill payment direct from MoMo — paying suppliers and salaries direct from the merchant wallet, with periodic reconciliation

Accounting treatment

1. Record each MoMo receipt as a sale — gross of MoMo fee. The MoMo fee is a separate expense line
2. Reconcile the MoMo wallet daily with the day's sales — discrepancies caught early are recoverable; week-old ones often are not
3. Treat the MoMo wallet as a bank account for accounting purposes — assets in the wallet are still business assets
4. File MoMo fees as a deductible business expense under CIT — fully deductible
5. Reconcile the MoMo statement against the EBM receipts monthly — RRA cross-checks if audited

Common mistakes

• Using the owner's personal SIM for the merchant wallet — creates KYC and inheritance/succession risk if the owner is unavailable
• Not issuing EBM receipts for MoMo payments — same penalty exposure as for cash transactions
• Mixing MoMo and bank-statement records inconsistently — produces gaps in the audit trail
• Letting the merchant wallet balance grow large — operational risk, lost-deposit insurance limits, opportunity cost
• Not training cashiers on the merchant-code dial-in procedure or confirmation check — fraud and dispute losses follow
