Looking for a POS system in Kenya that does more than simply print receipts?
For many businesses, a point-of-sale system is at the center of daily operations.
Every time a customer makes a purchase, your business may need to:
Record the sale
Process payment
Generate a receipt
Reduce inventory
Update customer records
Track sales
Calculate discounts
Monitor cash
Update accounting records
Produce reports
If these processes are handled separately, your employees may have to enter the same information multiple times.
A properly designed Point of Sale (POS) system can bring these activities together.
At WATT-IF LTD, we develop custom POS software for businesses that need a system designed around their products, sales process, inventory, branches, payment methods and reporting requirements.
🛒 Need a POS System Built for Your Business?
WATT-IF can develop a POS system with sales, inventory, receipts, customer management, M-Pesa and card payment integrations, reporting, user permissions and multi-branch functionality.
[Request a Custom POS Consultation]
A Point of Sale system is software used to process and manage sales transactions.
A simple POS workflow looks like:
Customer selects product
↓
Cashier scans/selects product
↓
POS calculates total
↓
Customer pays
↓
Receipt generated
↓
Stock updated
But a modern POS can do much more.
It can connect:
Sales
Inventory
Customers
Payments
Accounting
Reports
into one system.
Imagine running a shop where employees record sales manually.
A customer purchases:
2 shirts
1 pair of shoes
3 belts
The cashier has to calculate everything manually.
Then someone has to update inventory.
Then finance needs to record the sale.
Then management wants a report.
This creates multiple opportunities for errors.
With a POS:
Sale
↓
Payment
↓
Receipt
↓
Inventory update
↓
Sales report
The information can flow automatically.
Depending on your business requirements, WATT-IF can develop POS functionality for:
Sales
Products
Inventory
Customers
Suppliers
Payments
Receipts
Discounts
Taxes
Returns
Refunds
Purchases
Stock transfers
Branches
Cashiers
User permissions
Sales reports
Customer reports
Inventory reports
Accounting integration
A POS system needs a product database.
A product profile can contain:
Product name
SKU
Barcode
Category
Selling price
Cost price
Stock quantity
Supplier
Tax information
Product image
Reorder level
For example:
Product: Men's Shirt
SKU: SH-001
Price: KSh 2,500
Stock: 40
When a cashier sells the product, the system can automatically reduce the stock quantity.
Retail businesses can benefit from barcode functionality.
The workflow can be:
Scan barcode
↓
Product identified
↓
Price displayed
↓
Quantity added
↓
Total calculated
This can make checkout faster.
The exact hardware integration depends on the barcode scanner and POS environment.
A good POS system should not only record sales.
It should help you understand your stock.
For example:
Opening stock
500 units
↓
Sales
120 units
↓
Remaining stock
380 units
The system can maintain inventory records based on configured transactions.
📦 Want Your POS Connected to Inventory?
WATT-IF can develop POS and inventory functionality so sales transactions can update stock records automatically.
[Discuss POS & Inventory Integration]
A business doesn't want to discover that a popular product is out of stock only when a customer asks for it.
A POS system can monitor stock levels.
For example:
Product: Cooking Oil
Stock: 8 units
Reorder Level: 10
The system can flag the product for replenishment.
Businesses with multiple branches may move stock between locations.
For example:
Nairobi Branch
↓
Transfer 50 units
↓
Mombasa Branch
The POS/inventory system can record the transfer.
A cashier can select products or scan them.
The POS calculates:
Quantity
Unit price
Discount
Tax
Total
The customer then selects a payment method.
A POS can potentially support:
Cash
M-Pesa
Card
Bank transfer
Other configured payment methods
This gives customers more flexibility.
For Kenyan businesses, M-Pesa integration can be particularly useful.
A possible workflow is:
Customer purchases
↓
POS generates total
↓
Customer pays via M-Pesa
↓
Payment confirmation
↓
POS records payment
↓
Receipt generated
The exact implementation depends on the required M-Pesa API/service and business setup.
📱 Want M-Pesa Connected to Your POS?
WATT-IF can assess your POS requirements and develop the applicable M-Pesa integration workflow.
[Request M-Pesa POS Integration]
Businesses accepting card payments can potentially connect their POS to a supported payment provider.
For example:
POS
↓
Payment request
↓
Card terminal/payment gateway
↓
Payment confirmation
↓
Sale completed
The technical approach depends on the payment provider and hardware.
Some businesses need customers to pay using more than one method.
For example:
Total: KSh 10,000
M-Pesa: KSh 6,000
Cash: KSh 4,000
A custom POS can be designed to support split-payment workflows where required.
After a sale, the POS can generate a receipt.
It can include:
Company name
Logo
Branch
Receipt number
Items
Quantity
Price
Discounts
Tax
Payment method
Total
Date and time
Receipt design can be customized around the business.
Instead of printing every receipt, businesses may want digital receipts.
Depending on the system, receipts can potentially be delivered through:
SMS
Customer portal
Other configured communication channels
This can reduce paper usage.
A POS system can maintain customer profiles.
Information may include:
Customer name
Phone
Purchase history
Loyalty information
Outstanding balance where applicable
This turns the POS into more than a sales terminal.
A business can potentially see what a customer has purchased previously.
For example:
Customer: Jane
Purchases:
Shoes
Dress
Handbag
This information can support customer service and marketing, subject to appropriate privacy and data-handling practices.
A POS can support configured discounts.
For example:
Product: KSh 5,000
Discount: 10%
Final price: KSh 4,500
Discount permissions can be restricted to authorized employees.
Businesses can implement promotional pricing.
Examples include:
Buy one get one
Percentage discount
Fixed amount discount
Category promotion
Seasonal pricing
The appropriate rules depend on the business model.
Products can be organized into categories.
For example:
Electronics
Phones
Laptops
Accessories
Clothing
Shirts
Trousers
Shoes
This makes products easier for cashiers to find.
A POS connected to inventory can maintain supplier information.
For example:
Supplier
ABC Distributors
Products
Product A
Product B
Product C
The system can record purchasing and supplier-related information.
The system can potentially support:
Purchase order
↓
Supplier delivery
↓
Stock received
↓
Inventory increased
↓
Supplier balance updated
This connects procurement with inventory.
When new products arrive, staff can record the received stock.
For example:
Existing stock: 50
Received: 100
New stock: 150
The transaction can be recorded in the system.
Customers sometimes return products.
The POS can support a return workflow.
For example:
Original sale
KSh 10,000
↓
Customer returns product
↓
Return recorded
↓
Stock adjusted
↓
Refund/credit processed
The exact workflow can be configured according to the business's return policy.
A POS can record refunds.
For example:
Sale
KSh 5,000
↓
Refund
KSh 5,000
↓
Transaction recorded
Payment reversal depends on the payment method and applicable provider capabilities.
Some businesses sell on credit.
For example:
Customer purchase
KSh 50,000
↓
Payment
KSh 20,000
↓
Outstanding
KSh 30,000
A POS can be designed to support customer credit workflows where appropriate.
Each cashier can have an individual account.
The system can record:
Cashier
Sales
Payments
Refunds
Discounts
Shift information
This provides accountability.
For physical retail environments, the system can support cash drawer workflows.
For example:
Opening cash
KSh 20,000
Cash sales
KSh 80,000
Cash withdrawals
KSh 10,000
=
Expected closing cash
KSh 90,000
Actual cash can then be compared with expected cash.
Cashiers can start and close shifts.
For example:
Cashier: John
Opening balance: KSh 10,000
Sales: KSh 70,000
Expected cash: KSh 80,000
The system can record the shift summary.
Different employees can have different permissions.
Can:
Process sales
Print receipts
View permitted products
Can:
Approve discounts
Process returns
Can:
View reports
Manage products
Can:
Manage users
Configure system settings
If your business has several branches, one system can potentially manage them.
For example:
Nairobi
Mombasa
Kisumu
Nakuru
Each branch can have:
Cashiers
Inventory
Sales
Customers
Reports
Management can view individual or consolidated information.
One major benefit of multi-branch POS is centralized stock visibility.
Management can potentially see:
Nairobi
Product A: 20
Mombasa
Product A: 5
Kisumu
Product A: 30
This can help inform stock transfer and replenishment decisions.
A POS system can generate reports such as:
Daily sales
Weekly sales
Monthly sales
Sales by cashier
Sales by branch
Sales by product
Sales by category
Sales by payment method
Management can identify products generating the most sales.
For example:
Product | Units Sold |
|---|---|
Product A | 450 |
Product B | 320 |
Product C | 210 |
This can help with purchasing and inventory planning.
Management can see how customers are paying.
For example:
M-Pesa: KSh 500,000
Card: KSh 250,000
Cash: KSh 150,000
Bank: KSh 100,000
This can help with reconciliation.
Your POS can potentially communicate with your accounting system.
For example:
Sale
↓
POS
↓
Invoice/Receipt
↓
Accounting
↓
Revenue
This avoids manually entering every sale into accounting.
The relationship is straightforward:
Sale
↓
Stock decreases
Purchase
↓
Stock increases
Return
↓
Stock adjusted
This creates a more accurate inventory record.
A customer purchase can potentially be transferred into the CRM.
For example:
Customer
↓
Purchase
↓
CRM
↓
Customer history
↓
Marketing
This can support customer relationship management.
If you sell both online and in physical stores, integration can be extremely valuable.
For example:
POS sale
↓
Inventory
Online sale
↓
Inventory
Both channels can potentially use the same inventory database.
This helps reduce discrepancies between online and physical stock.
🛍️ Selling Online and in a Physical Store?
WATT-IF can help you explore connecting your website or e-commerce store with POS and inventory systems.
[Discuss E-Commerce & POS Integration]
If you already have another system, an API can connect it to the POS.
For example:
E-commerce
↓
API
↓
POS
or:
POS
↓
API
↓
Accounting
or:
POS
↓
API
↓
Inventory
This can create a connected business environment.
Depending on the business, a mobile POS application can be developed.
A mobile POS could potentially allow authorized users to:
Process sales
View products
Check stock
View customers
Process supported payments
Generate digital receipts
The functionality depends on the project.
Some businesses operate in environments where internet connectivity can be unreliable.
An offline-capable POS can potentially store certain transactions locally and synchronize them when connectivity returns.
This requires careful system architecture to avoid duplicate transactions or conflicting inventory records.
Management can have a dashboard showing:
KSh 350,000
420
Product A
12
8
The exact metrics can be customized.
At WATT-IF, we don't assume every business needs the same POS.
A supermarket, pharmacy, restaurant, clothing store and electronics shop may have completely different requirements.
We determine:
What you sell
Number of products
Number of branches
Number of cashiers
Payment methods
Inventory process
Purchasing process
Customer management requirements
Existing software
For example:
Customer
↓
Product selection
↓
Checkout
↓
Payment
↓
Receipt
↓
Inventory update
↓
Accounting
This becomes the foundation of the system.
We determine:
Product categories
SKUs
Barcodes
Pricing
Stock locations
Reorder levels
Suppliers
The cashier interface should be simple and fast.
It can include:
Search
Categories
Products
Cart
Discount
Payment
Receipt
We build the POS according to the approved requirements.
Depending on requirements:
M-Pesa
Cards
Bank
Other supported payment methods
can be incorporated.
Sales can be connected to stock movements.
Where required, POS transactions can be connected to accounting.
We test:
Sales
Payments
Refunds
Returns
Discounts
Inventory
Receipts
User permissions
Reports
Training can cover:
Sales and payments.
Returns and approvals.
Products and reports.
Users and system configuration.
The POS can be deployed according to your chosen infrastructure and hardware environment.
We can continue supporting the system through:
Bug fixes
Feature improvements
Integrations
Security updates
New reports
Additional branches
There is no single price for a POS system.
A basic POS may include:
Products
Sales
Receipts
Cashiers
Basic reports
A more advanced system may include:
Inventory
Purchasing
Suppliers
Customers
M-Pesa
Cards
Accounting
CRM
E-commerce
Multi-branch
Offline operation
Mobile application
Advanced reporting
These systems have significantly different development requirements.
One shop is simpler than 20 branches.
A small catalog differs from a large inventory.
The system architecture and permissions depend on the expected usage.
M-Pesa and card integrations add development requirements.
Advanced stock management increases complexity.
Connecting POS to accounting requires integration work.
Connecting online and physical sales requires additional architecture.
Barcode scanners, receipt printers, cash drawers and other devices may require compatibility testing or integration.
A mobile POS adds another software component.
A simple POS can be significantly faster to develop than a full retail management platform.
For example, a system containing:
Sales + Receipts
is much smaller than:
Sales + Inventory + Purchasing + Suppliers + Customers + M-Pesa + Accounting + Multi-Branch + E-commerce

A POS shouldn't simply be a place where a cashier enters a sale.
It can become the central point connecting your business operations.
At WATT-IF, we can combine:
POS
Inventory
Accounting
CRM
Payments
E-commerce
API Development
Mobile Applications
to create a connected system.
For example:
Customer
↓
Purchase
↓
POS
↓
M-Pesa/Card/Cash
↓
Receipt
↓
Inventory Updated
↓
Accounting Updated
↓
Customer History Updated
↓
Management Dashboard
This means one transaction can provide useful information across different parts of the business.
You don't necessarily need to change your business processes to fit generic software.
A custom POS can be designed around:
Your products
Your pricing
Your branches
Your employees
Your payment methods
Your inventory
Your accounting process
Your customers
Your reports
That's the advantage of custom software development.
