A customer finds your online store, picks out a pair of shoes, and fills their cart. They click checkout. The page asks for a credit card number. They close the tab.
This is not a hypothetical. From our experience, this is the single most common reason for abandoned carts on Kenyan e-commerce sites. The customer was ready to buy. They had the money. But the payment method did not match how they pay for things.
For a retailer in Kenya, adding M-Pesa to your checkout is not just another feature. It is the feature that decides whether your website is a sales channel or a digital brochure.
The numbers do not lie — M-Pesa is the market
Let us start with the scale. According to a report shared by Safaricom, there are around34 millionM-Pesa subscribers in Kenya as of November 2024. That is more than half the country's population. The Communications Authority of Kenya's Q3 2024-2025 report shows mobile money subscriptions grew by 7.2% to over 45 million.
Now, think about your customers. According to Statcounter data, Android holds over 90% of Kenya's mobile operating system market. Most of your traffic is coming from people on Samsung, Tecno, or Infinix phones, using those phones to browse and shop.
These users are not just familiar with M-Pesa. It is their default. Paying for electricity, sending money home, buying airtime — it all happens through that green SIM toolkit menu or the Safaricom app. When they get to your checkout and do not see the option they use every day, trust evaporates.
34 Million— The number of M-Pesa subscribers in Kenya as of November 2024, according to Safaricom. For context, that is more than the combined populations , Mombasa, Kisumu, and Nakuru.
What you lose when you skip M-Pesa
The loss is not just one sale. It is a pattern. From our experience working with retailers, a site without M-Pesa sees two clear problems:
- Higher cart abandonment: Customers simply leave. They might call your number if it is listed, but many will just go to a competitor whose checkout works for them.
- Lower average order value: When payment is frictionless, people buy more. If they have to stop and figure out how to pay, they stick to the bare minimum or abandon the cart entirely.
Think about Jumia and Kilimall. Their growth in Kenya is not just about having lots of products. A big part of it is that they integrated mobile money payments early, making it convenient and secure for customers to pay. They removed the biggest barrier to buying online.
It is more than a button — it is about trust
A checkout is where trust is finalized. A customer is about to part with their money. Seeing a payment method they recognize and use daily — one that is regulated and has consumer protection — makes that final click easier.
This is also a search engine problem. Many Kenyan shoppers specifically search for stores that accept M-Pesa. Mentioning “M-Pesa accepted” on your product pages is not just good for users — it is a keyword opportunity most stores ignore, as noted by digital marketers in Kenya.
Without those signals, you are invisible to a segment of buyers who filter for convenience and local relevance.
How to add it — and what it costs
The good news is, adding M-Pesa is one of the most straightforward integrations for a Kenyan website or app. You have a few paths:
- Direct API integration: Using Safaricom's Daraja API. This is for custom-built sites and gives you the most control. It is what we use for clients who need a tailored checkout flow.
- E-commerce platform plugins: If you use a system like WooCommerce, there are reliable plugins that handle the connection. They are quicker to set up but offer less customization.
- Third-party payment aggregators: Services that bundle M-Pesa with other options. This can be easier but often comes with higher per-transaction fees.
From our experience, for a full custom e-commerce app, development guides in Kenya estimate costs from KES 250,000 to over KES 1,500,000, depending on features. The M-Pesa integration itself is a defined part of that cost. For adding it to an existing website, the investment is significantly lower and is almost always justified by the recovery of lost sales.
The drawer is digital now
Remember the shop owner at the beginning, watching customers abandon their carts? The fix is not a louder marketing campaign or more products. It is fixing the last step — the moment money should change hands.
In Kenya, the cash drawer is no longer just physical. It is the M-Pesa till number on your website. If a customer cannot find it, or if the process to use it is clunky, they walk away. Your job is to make that digital drawer as easy to open as the wooden one in your shop.
Look at your analytics. Check your cart abandonment rate. If it is high, look at the payment page. The answer is probably right there, in the one feature your checkout cannot afford to skip.
