A salon owner in Kigali has been taking mobile money payments into her personal MTN account since she opened. Business is good, good enough that she’s started hitting her daily transfer limit some Saturdays, and her accountant keeps asking her to separate personal spending from salon income before tax season. She has never actually compared what a merchant wallet would cost her against what it’s already costing her to not have one.
That’s a common position for a growing Rwandan SME. Personal wallets work fine at low volume, free, familiar, no paperwork. Past a certain point they start creating two separate problems: transfers that fail once you hit the daily limit, and mixed personal and business funds that create real exposure if the Rwanda Revenue Authority ever audits you.

Moving from a personal wallet to a merchant wallet isn’t just a fee decision, it’s a short registration process. Both MTN and Airtel require your RDB certificate, TIN, the legal representative’s ID, and proof of business location, at a business centre. Merchant codes are typically issued within 1 to 5 business days, after which you can set up settlement to your business bank account on your own schedule.
FAQ
Why does a personal wallet stop working as a business grows?
Two reasons. Personal wallets carry a daily transfer limit, typically RWF 1 to 2 million depending on your KYC tier, and once your business volume exceeds it, transactions start failing. Second, mixing personal and business funds in one wallet complicates your accounting and creates exposure if the Rwanda Revenue Authority audits your business income.
Is MTN MoMo Pay or Airtel Money cheaper for merchants?
Both networks typically charge in the same 1 to 1.5 percent range per inbound transaction as of 2026, so the cheaper option usually comes down to your specific negotiated rate rather than a fixed difference between the networks. Use the calculator with your actual quoted rates to see which wins at your volume.
Does the customer pay anything extra to pay a merchant?
No. Paying into a merchant code carries no cost to the customer on either network, which is part of what drives merchant adoption. The 1 to 1.5 percent fee is charged to the merchant receiving the payment, not the person paying.
How long does it take to get a merchant code?
Typically 1 to 5 business days after submitting your RDB certificate, TIN, legal representative’s ID, and proof of business location at an MTN or Airtel business centre.
Can I settle merchant wallet funds to my bank account automatically?
Yes. Both networks let you set up settlement from your merchant wallet to a business bank account at agreed daily or weekly intervals once your merchant code is active.
