What it means
The name combines M for mobile and pesa, the Swahili word for money. A customer registers with an agent, who might be a small shop, and then deposits cash in exchange for electronic value stored on their phone account.
The customer can send that value to anyone with a phone number, pay bills or buy goods, and later withdraw it as cash at an agent. The service works on basic phones as well as smartphones, using simple menus rather than a full internet connection.
That feature mattered in places where few people had bank accounts or internet access. A shopkeeper far from the nearest bank branch could suddenly receive payments from distant customers.
The economics rest on a few sources of income. The operator earns small fees on transfers and withdrawals, agents earn commissions for handling cash, and the platform generates float, which is the total of customer balances held in bank accounts as backing for the electronic money.
Rules in each country require that customer funds be safeguarded. M-Pesa has grown beyond transfers.
It is used for salaries, school fees, utility bills, merchant payments and, through partnerships, savings and small loans. For businesses, it can reduce the cost of collecting payments and make it easier to serve customers who cannot use cards.
There are nuances. Fees can feel high on small transfers, regulation differs between countries, and the service depends on the reliability of the mobile network and the agent network.
Operators must also guard against fraud and money laundering. Competition and regulation continue to shape the market.
Banks, fintech start-ups and other mobile operators offer rival wallets, and regulators watch pricing, consumer protection and the safety of customer balances. Businesses choosing a payment provider should compare fees, reach and reliability before committing.
In practice
Real-world examples.
Example
A farmer in a rural area sells vegetables to a trader in the city. The trader pays through mobile money, and the farmer collects the cash at a nearby agent the same day, avoiding a long journey to a bank.
Example
A small retailer in Nairobi starts accepting mobile payments at her till. She no longer has to count large amounts of cash overnight, and her accountant finds it easier to reconcile daily takings against the phone statement.
Example
A charity that supports schools sends bursary payments directly to parents' phones. The finance team gets a digital record of every transfer, which makes the audit simpler and reduces the risk of cash going missing.
Formula
Calculation
Transaction fee revenue = Number of customers x Transactions per customer x Average value x Fee rate
Suppose, for illustration, that a mobile money service has 2,000,000 active customers. Each makes 12 transfers a year, averaging $50, and the operator earns an average fee of 1.5% of the value. Number of transactions = 2,000,000 x 12 = 24,000,000. Total value = 24,000,000 x 50 = $1,200,000,000. Fee revenue = 1,200,000,000 x 0.015 = $18,000,000 a year.Case study
Seen in the real world.
Savannah Fresh Produce is an illustrative, fictional exporter that buys from 400 small farms. Previously it paid in cash at weekly collection points, which meant carrying large sums, paying security guards and dealing with disputes over amounts. The finance manager proposed moving payments to a mobile money service.
After the switch, each farmer received payment directly on their phone the moment their produce was weighed. The fictional company calculated that it saved about $18,000 a year in security and handling costs, paid transaction fees of roughly $9,000, and gained a reliable digital record. The farmers valued the speed and safety, and loyalty to the company improved.
The finance manager added a control to the process. Each week the company reconciled the mobile money statement with its payment records, and any mismatch above $50 was investigated, which kept the fictional programme clean and auditable.
Watch out
Common mistakes.
- Treating mobile money as the same as a bank account, when the products are regulated differently and offer different services.
- Ignoring the fees on small transfers, which can add up for frequent users and businesses.
- Assuming it only works with smartphones, when its basic design was built for simple phones.
Questions
People also ask.
Who runs M-Pesa?
It was launched by Safaricom, a Kenyan mobile operator, and is operated with partners in the countries where it is available.
Do customers need a bank account?
No, a registered phone number and an agent for cash deposits and withdrawals are enough to start using the service, although identity checks are required by regulators in most countries.
How are customer funds protected?
Regulators typically require that the value held for customers is backed by deposits in regulated banks, kept separate from the operator's own funds, so that customers are paid even if the operator fails.
