Do you want your customers to pay for products and services directly through your website, mobile application or business system using M-Pesa?
For businesses operating in Kenya, M-Pesa is an important payment method for reaching customers who prefer mobile payments. However, there is a major difference between simply displaying an M-Pesa number on your website and having a properly integrated M-Pesa payment solution.
With a professional M-Pesa integration, your website or business system can be connected to the payment process so that customers can initiate payments online, transactions can be tracked, and confirmed payments can be linked to orders, invoices, bookings, subscriptions or other business activities.
At WATT-IF LTD, we provide payment integration and software development solutions that can help businesses connect M-Pesa to websites, e-commerce platforms, mobile applications and custom business systems.
Need M-Pesa Payments on Your Website or App?
WATT-IF can help you integrate M-Pesa into your website, e-commerce store, mobile application or custom business system.

M-Pesa payment integration is the process of connecting a website, mobile application or business software to M-Pesa through the appropriate APIs and payment services.
The purpose is to allow your business system to communicate with the payment platform and process transactions as part of your normal customer journey.
For example, instead of asking a customer to manually make a payment and then send a screenshot, your website can be designed to guide the customer through an online payment process.
A typical customer journey may involve:
The customer selects a product or service.
The customer proceeds to checkout.
The customer selects M-Pesa as the payment method.
The payment request is initiated.
The customer authorizes the transaction.
The payment provider processes the transaction.
Your system receives the relevant payment response.
The order, invoice or account can be updated based on the confirmed transaction.
The customer can receive an appropriate confirmation or receipt.
Safaricom's Daraja platform provides APIs that enable developers to integrate M-Pesa functionality with web and mobile applications.
Many businesses make payments possible by displaying an M-Pesa Till Number, PayBill number or other payment instructions on their website.
For example:
"Pay KSh 5,000 via M-Pesa to our Till Number XXXXX."
While this allows customers to pay, the payment is not necessarily connected to the website's ordering or accounting system.
The customer may have to:
Make the payment manually.
Copy the transaction code.
Send the transaction code to the business.
Wait for someone to verify the payment.
Wait for the order to be confirmed.
This can become difficult when your business receives many payments.
With an integrated payment solution, the payment process can become part of the website or application itself.
The difference is essentially between accepting M-Pesa payments and integrating M-Pesa into your business operations.
The main benefit of payment integration is that it can reduce the amount of manual work involved in processing customer payments.
Imagine an online store receiving 100 orders per day.
If employees have to manually check every payment, match transaction codes to orders and update each order, the process can consume considerable time.
A properly designed system can automate many of these steps.
Easier customer checkout
Faster payment confirmation
Reduced manual verification
Automatic order updates
Better transaction records
Integration with invoices
Integration with inventory
Integration with accounting systems
Improved customer experience
Better payment tracking
Easier reconciliation
Reduced administrative workload
The exact level of automation depends on the payment service, system architecture and requirements of your business.
Turn Your Website Into a Payment Platform
Your website should do more than display your products and services. It can help customers discover your business, place orders, make payments and receive confirmations.
WATT-IF can help you build and connect these functions.
Request a Website & M-Pesa Integration Consultation
Although the technology behind payment integration can be complex, the concept is relatively simple.
Your website or application communicates with your backend system. The backend communicates with the applicable M-Pesa API. The payment process is then initiated and the relevant transaction information is returned to your system.
Your software can then use that information to determine what should happen next.
For example, if a customer purchases a product, the system could associate the confirmed payment with the relevant order and update the order status.
The important point is that payment becomes connected to your business process rather than remaining a separate activity.
An API, or Application Programming Interface, allows different software systems to communicate with one another.
You can think of an API as a communication mechanism between your software and the payment platform.
Your website may need to request a payment.
The payment platform processes the request.
The customer authorizes the payment.
The relevant transaction information is then communicated back to the appropriate system.
This communication allows developers to create more automated payment experiences.
Safaricom's Daraja platform provides developers with access to M-Pesa APIs and documentation for building integrations.
One of the payment experiences associated with M-Pesa online integration is STK Push.
Instead of requiring the customer to manually navigate through the M-Pesa menu and enter payment details, the payment request can be initiated electronically and presented to the customer's mobile device for authorization.
This can make the checkout process more convenient.
For example, a customer shopping on your website could:
Add a product to their cart.
Proceed to checkout.
Select M-Pesa.
Enter the required mobile number.
Receive the payment prompt.
Authorize the payment.
Return to the website after the transaction.
The exact implementation and requirements depend on the M-Pesa service and merchant setup being used.
One of the most important parts of any payment integration is confirming whether the transaction was actually completed.
A website should not simply display:
"Payment Successful"
because a customer clicked a payment button.
The system needs to handle the actual payment response and determine the transaction status appropriately.
This is important because payments can be:
Successful
Failed
Cancelled
Pending
Delayed
Interrupted
A properly designed system should know how to handle these different situations.
For example, if a customer attempts to pay for a KSh 10,000 product but the payment fails, the order should not automatically be treated as paid.
This is why payment integration requires proper backend development, transaction handling and testing.
During payment integration, you may hear developers use terms such as callbacks, webhooks or payment notifications.
These mechanisms allow payment systems to communicate relevant transaction information back to your application.
For example, your website may initiate a payment request, but the customer could take several moments to authorize it.
Your system needs a reliable way to receive the eventual payment information.
The payment notification can then be used to update the relevant transaction.
This is particularly important for:
E-commerce orders
Invoices
Bookings
Subscriptions
School fees
Hospital bills
Service payments
Mobile applications
If you operate an online store, payment integration can become an important part of the entire customer journey.
Consider a customer buying a product from your website.
The customer should be able to:
Browse products
Select a product
Add it to the cart
Review the order
Enter their details
Select a payment method
Make the payment
Receive confirmation
Track the order
M-Pesa can become part of that checkout process.
Once payment is appropriately confirmed, your system can potentially update the order and trigger other processes.
For example, the order may move from Pending Payment to Paid, after which the business can begin processing the order.
Do You Already Have an Online Store?
If your website already has products and a shopping cart but customers cannot conveniently pay online, WATT-IF can assess your existing system and recommend an appropriate payment integration.
Get Your E-Commerce Payment System Started
M-Pesa integration is not limited to websites.
It can also be incorporated into mobile applications where appropriate.
Examples include:
E-commerce apps
Delivery apps
Booking applications
Transport applications
School applications
Hospital applications
Event applications
Membership applications
Service marketplaces
Subscription applications
Business applications
For example, a customer using a delivery application could place an order and pay as part of the application's checkout process.
The payment information can then be communicated to the application's backend, allowing the relevant order to be processed according to the business rules.
WATT-IF provides both mobile application development and payment integration, allowing these services to be developed together where required.
Businesses that send invoices can also benefit from connecting payments to their invoicing systems.
Imagine that your company sends a customer an invoice for:
KSh 50,000
Instead of sending separate payment instructions and manually checking whether the invoice has been paid, you can create a payment-enabled workflow.
The customer receives the invoice, chooses to pay, completes the payment and the system can update the invoice once the applicable transaction is confirmed.
This can help reduce manual reconciliation.
It can also provide your finance team with a clearer record of:
Invoice number
Customer
Amount
Payment status
Transaction reference
Payment date
Enterprise Resource Planning systems bring different areas of a business together.
An ERP can include:
Sales
Purchasing
Inventory
Accounting
Customer management
Invoicing
Reporting
Connecting M-Pesa to an ERP can help integrate payments into these workflows.
For example, when a customer pays an invoice, the payment information can be associated with the relevant customer and invoice records.
This is particularly useful for businesses that process a large number of transactions.
WATT-IF develops custom ERP and business management systems and can incorporate payment integrations into suitable projects.
Customer payments can also be relevant to customer relationship management.
A CRM can contain information about:
Customers
Leads
Sales
Orders
Communications
Customer history
Where appropriate, payment information can be connected to the customer record.
This can help businesses understand customer activity and maintain a more complete customer history.
For example, a sales representative may be able to see that a particular customer has:
Purchased a service
Received an invoice
Completed a payment
Renewed a subscription
The exact functionality depends on the CRM architecture and integration requirements.
For businesses selling physical products, payment and inventory can be connected.
For example, after a confirmed customer payment, the business system may update the order and subsequently reduce the available inventory according to its configured workflow.
This can help businesses maintain better control over stock.
For example:
Product stock before order: 50 units
Customer purchases: 2 units
Updated stock: 48 units
The actual inventory update should be based on the business's order and fulfillment rules rather than simply assuming that every payment attempt represents a completed sale.
Schools increasingly use digital systems to manage students, fees and administration.
A school management system can include:
Student records
Fee structures
Fee balances
Invoices
Receipts
Academic records
Parent information
Reporting
M-Pesa integration can be incorporated into the financial side of such a system.
A parent could receive a fee balance and make a payment through an applicable M-Pesa workflow.
The school system can then associate the confirmed payment with the correct student account.
This can reduce the amount of manual data entry required by the school administration.
Hospitals and medical facilities can also use payment integration as part of their management systems.
For example, a hospital system may contain:
Patient information
Billing
Invoices
Services
Payments
Receipts
Reports
An integrated payment process can help connect a patient's bill with their payment transaction.
This can improve the organization's ability to track outstanding balances and completed payments.
Businesses that rely on bookings can use payment integration to collect deposits or full payments.
Examples include:
Hotels
Event venues
Travel companies
Consultants
Training providers
Appointment businesses
Rental companies
A customer can select a service or booking, proceed to payment and receive confirmation after the relevant transaction is successfully processed.
This can reduce the need for staff to manually confirm every booking payment.
Subscription businesses charge customers repeatedly for access to a service.
Examples include:
SaaS platforms
Membership websites
Online learning platforms
Software services
Digital services
Professional services
Payment integration can become part of the subscription management process.
However, subscription and recurring-payment requirements need to be designed carefully because the available recurring-payment functionality depends on the payment provider and merchant setup.
WATT-IF can help businesses assess their requirements and develop the appropriate payment and subscription workflow.
One of the biggest advantages of working with a software development company for payment integration is that payment does not have to remain isolated.
For example, WATT-IF can develop solutions where payment functionality works alongside:
Websites
Mobile applications
ERP systems
CRM systems
POS systems
Inventory systems
Accounting systems
Invoicing systems
Booking systems
School systems
Hospital systems
This means you can build a connected digital environment around your business.
At WATT-IF, our approach begins with understanding your business rather than simply installing a payment feature.
We first determine what you need the payment system to accomplish.
For example:
Do you sell products?
You may need an e-commerce checkout.
Do you sell services?
You may need invoices and online payments.
Do you operate a school?
You may need fee management and payment records.
Do you operate a hospital?
You may need billing and payment integration.
Do you run a SaaS platform?
You may need subscriptions and account activation.
The solution should therefore be designed around your business process.
We discuss:
Your business
Your customers
Your products or services
Your existing website
Your existing software
Your payment requirements
Your expected transaction volume
Your accounting process
Your invoicing process
Your reporting requirements
This helps determine the most suitable technical approach.
If you already have a website or application, we assess its technology and architecture.
This may include:
Website platform
Backend technology
Database
Existing checkout
Hosting
Security
Existing payment integrations
API capabilities
Sometimes the existing system can be integrated directly.
In other situations, improvements or redevelopment may be necessary.
We determine exactly what should happen when a customer pays.
For example:
A customer purchases a product.
The system creates an order.
The customer proceeds to payment.
The M-Pesa payment is initiated.
The customer authorizes the transaction.
The system receives the relevant payment information.
The transaction is associated with the order.
The order status is updated based on the confirmed transaction.
The customer receives the appropriate notification.
This workflow is then implemented according to the project requirements.
WATT-IF handles the technical development required to connect your system with the applicable M-Pesa services.
This can include:
API authentication
Payment initiation
Transaction references
Callback handling
Payment status handling
Database integration
Error handling
Transaction logging
Customer notifications
Administrative reporting
Payment systems should be tested thoroughly before being used for real transactions.
Testing may include:
Successful payments
Failed payments
Cancelled payments
Delayed transactions
Incorrect amounts
Duplicate transaction handling
Network interruptions
Callback handling
Order updates
Invoice updates
Receipt generation
Safaricom provides a Daraja sandbox environment that developers can use during development and testing.
Once the integration has been tested and the required merchant configuration is in place, the solution can be prepared for production.
WATT-IF can assist with the technical deployment and configuration required for your project.
Payment integration isn't complete if your staff don't know how to use the system.
Depending on the project, WATT-IF can train your team on:
Viewing transactions
Checking payment status
Managing orders
Managing invoices
Generating reports
Handling failed payments
Understanding payment records
Managing customers
Training requirements will depend on the system we develop for you.
Your business and technology will continue to change after the initial integration.
You may later want to:
Add another payment method
Add card payments
Add Airtel Money
Add an online store
Add subscriptions
Connect accounting software
Develop a mobile app
Upgrade your website
Add a CRM
Build an ERP
WATT-IF can support the continued development and maintenance of your digital systems.
There is no universal price for M-Pesa integration because every project is different.
A simple integration into an existing website may require significantly less work than developing a complete e-commerce platform with payment integration, inventory management, accounting and customer management.
The cost may depend on:
A well-developed website may be easier to integrate than an outdated or poorly structured platform.
The development requirements can vary depending on whether you use WordPress, WooCommerce, Laravel, PHP, Node.js, a custom application or another technology.
A simple payment workflow is different from a complete online checkout.
You may need payment to trigger:
Order confirmation
Invoice updates
Inventory changes
Account activation
Booking confirmation
Receipt generation
The project may also involve:
Accounting
CRM
ERP
POS
Inventory
SMS
Mobile applications
For this reason, WATT-IF recommends assessing the project before giving a final development quotation.

The development time depends on the complexity of the project.
For example, integrating an applicable payment workflow into an existing compatible website may be relatively straightforward.
However, developing a complete system involving:
Website
E-commerce
Checkout
M-Pesa
Inventory
Invoicing
Accounting
Customer management
will naturally require more development and testing.
Before beginning development, WATT-IF can assess your requirements and provide an estimated project timeline.
A properly designed payment workflow can reduce reliance on customers manually sending screenshots by connecting the payment process to your system.
Payment integration can automate relevant parts of transaction confirmation and order processing.
WATT-IF can assess your website and implement an appropriate payment solution.

Security should be a major consideration when developing any payment system.
At WATT-IF, payment integrations should be designed with appropriate security practices, including:
Secure API credentials
HTTPS
Server-side processing
Appropriate authentication
Transaction verification
Access controls
Error handling
Transaction logging
Protection against duplicate processing
Your website should also be properly secured and maintained.
It is important to remember that security is not only about the payment API. Your website, hosting environment, database, administrator accounts and application code also need appropriate security measures.
Choosing a payment integration provider is not only about finding someone who can connect an API.
You need a solution that fits your business.
