How to accept M-Pesa, Mixx by Yas and Airtel Money on your website in Tanzania

The short answer

To take mobile money on a website in Tanzania, you sign up with a payment provider licensed by the Bank of Tanzania, connect it to your store with a plugin or its API, and let it handle the wallets. The customer types their phone number at checkout, approves the payment on their phone, and your store marks the order paid when the provider confirms.

The decisions that matter are which provider you choose, what you pay it, and how carefully the checkout handles the confirmations. The rest of this guide covers each one.

Which wallets to support

Support the three big wallets at minimum, and HaloPesa if your provider offers it at no extra effort. TCRA’s figures for March 2026 put the three largest at nine in ten mobile money subscriptions:

Active mobile money subscriptions reached 87.05 million in June 2026. Tigo Pesa became Mixx by Yas in November 2024, so older plugins and documentation may still call it Tigo Pesa. It is the same wallet.

How a mobile money checkout works

Almost every provider uses the same pattern, often called USSD push:

1. The customer chooses mobile money and enters their phone number.
2. Your site asks the provider to start a payment for that number and amount.
3. The customer’s phone shows a prompt from their network. They approve with their PIN.
4. The provider sends your site a confirmation (a webhook), and your site marks the order paid.

Step 4 is where most problems start. Build the checkout to expect them:

• The customer never approves. The prompt times out. The order should stay unpaid and let them try again, not vanish.
• The confirmation arrives late. Networks are sometimes slow. The site should check the transaction status with the provider before telling the customer anything.
• The confirmation arrives twice. Webhooks can repeat. Mark an order paid once, whatever happens next.
• The wrong number or not enough balance. Show a clear message and a retry button, in plain words.
• Nobody notices a mismatch. Reconcile the provider’s daily report against your orders, automatically if possible. We set this up as an n8n workflow that flags anything that does not match.

One provider, or each network directly

Vodacom, for example, runs an M-Pesa developer portal for businesses that want to integrate directly. For most stores the extra contracts and reconciliation outweigh the saving until volumes are high.

Payment providers compared

Five providers that offer online checkout in Tanzania. The table records what each provider’s own pages and official listings said on 14 October 2026. We are not paid by any of them, and inclusion is not an endorsement.

Two things stand out. First, no one publishes a full price list for Tanzania, so you will need quotes. Second, both WooCommerce plugins we checked carry WordPress.org’s warning that they have not been tested with the latest three major WordPress releases. That does not mean they are broken, but it does mean someone should test them on a staging copy before every WordPress update.

Shopify or WooCommerce for mobile money

Shopify works if your provider has a Shopify app that covers Tanzania. Shopify Payments is not offered in Tanzania, so every payment goes through a third-party provider, and Shopify charges its own third-party transaction fee on those payments: 2% on Basic, 1% on Grow and 0.6% on Advanced on its published pricing. That is on top of what the provider charges you.

WooCommerce has no platform fee and more Tanzanian provider plugins to choose from, and a developer can connect any provider with an API. The trade-off is that you, or someone you pay, look after hosting, updates and security.

On a store taking TZS 20,000,000 a month, Shopify’s 2% Basic-plan fee is TZS 400,000 a month before the provider’s own charge. That single number often decides it. For the full comparison, see WooCommerce vs Shopify for small business.

Questions to ask a provider before you sign

Ask for the answers in writing. They decide what mobile money really costs you:

1. What is your fee per collection for each wallet, and for local and international cards?
2. Is there a setup fee, a monthly fee or a minimum volume?
3. How long after a payment does the money reach my bank account, and is there a payout fee?
4. Which wallets and card brands are live today, not “coming soon”?
5. How do refunds work for mobile money, and what do they cost?
6. Do you have a sandbox, and how long does KYC approval usually take?
7. Do you send webhooks, and can I query a transaction’s status by API?
8. Do you provide a daily settlement report I can download or fetch automatically?
9. Is your plugin maintained, and which WordPress and WooCommerce versions is it tested with?
10. Who do I call when a payment fails, and in what hours?
