Open
In Nakuru, a cosmetics shop opens at 7 am. The owner counts cash from the till, checks the M-Pesa balance on her phone, and then opens a WhatsApp group to ask the boda-boda rider if the evening stock has arrived. She spends the next 45 minutes copying sales numbers from a paper notebook into a spreadsheet, trying to match each M-Pesa STK push with the correct item. By the time she finishes, the morning rush is already building and she has missed a few walk-in customers who left because the line was too long.
The problem
Manual counts eat up selling time
Every day the shop owner loses at least an hour reconciling cash, M-Pesa, and stock levels. That time could be spent serving customers or sourcing new products. In our experience, businesses that rely on spreadsheets and WhatsApp for inventory lose roughly 2-3 hours per shift to manual work.
Marketplace fees erode thin margins
Selling on Jumia or Kilimall gives instant reach, but each order carries a commission plus logistics fees. For low-margin items like cosmetics or groceries, those fees can turn a profitable sale into a loss, especially when the owner still has to handle returns and refunds manually.
No real-time view across channels
When the same product is listed on a marketplace and sold over the counter, the owner has no automatic way to deduct inventory. This leads to overselling, stock-outs, and frustrated customers who receive a cancellation notice after waiting for delivery.
How it works in Kenya
M-Pesa as the core payment rail
STK push, paybill, and till numbers let customers pay instantly from their phones. A properly integrated system records each transaction in the sales ledger, matches it to the invoice, and updates inventory without the owner having to copy numbers from SMS.
KRA eTIMS-ready invoicing
Every sale, whether online or in-store, must generate an eTIMS-compliant invoice. The system creates the invoice in the required JSON format, sends it to KRA, and stores a copy locally for audit. This removes the end-of-month scramble to produce paper invoices.
WhatsApp as a business channel, not a data store
Many teams use WhatsApp to share stock updates or delivery instructions. A connected platform can push those same updates automatically to the staff’s phones via a simple bot, keeping the conversation for service while the system holds the true record.
Mobile-first, offline-capable storefront
Over 80 % of Kenyan shoppers browse on phones. A lightweight website that works offline—showing product catalog, accepting M-Pesa STK push, and storing orders locally—lets customers buy even when the network drops. Orders sync when connectivity returns, preserving every sale.
Where businesses go wrong
Treating the marketplace as a replacement for own store
Relying only on Jumia means paying commission on every sale and losing direct customer data. When the marketplace changes its fees or suspends an account, the business has no fallback sales channel.
Skipping inventory synchronization
Adding a website without linking it to the POS leads to double-selling. The owner ends up manually adjusting stock each night, which defeats the purpose of going online.
Underestimating reconciliation effort
Some owners integrate M-Pesa payments but forget to automate the matching of each transaction to an order. The result is a growing pile of unmatched SMS notifications that must be cleared manually at month-end.
Ignoring offline capability outside Nairobi
In Kisumu or Mombasa, power outages and spotty 3G are common. A storefront that requires a constant internet connection stops sales during those periods, pushing customers back to cash-only competitors.
The path forward
Before: marketplace only, manual reconciliation
The shop owner spends mornings updating spreadsheets, loses sales to stock-outs, and pays high commissions. She cannot see which products move fastest because data is scattered across marketplace reports, WhatsApp chats, and paper receipts.
After: own store integrated with POS and inventory
A simple website shows the full catalog, accepts M-Pesa STK push, and writes each sale directly into the POS. Inventory levels drop in real time, whether the sale came from the website or the counter. At closing, the system prints an eTIMS invoice and reconciles M-Pesa automatically—no spreadsheets needed.

Common questions
Will I lose my existing marketplace sales if I build my own store?
No. You can keep the marketplace as an additional channel while directing new customers to your own site. Many clients run both in parallel, using the own store for higher-margin items and the marketplace for clearance stock.
How long does it take to go from discovery to a live site?
A typical website with M-Pesa and basic inventory takes 4–6 weeks from sign-off to launch, delivered in weekly increments you can test.
Do I need to be tech-savvy to run the system?
The interface is designed for mobile-first use with large buttons and Swahili/English labels. We provide a half-day training session and 24/7 local support from Nairobi for any questions.
What happens if the internet goes down during the day?
The offline-first architecture lets staff continue to take sales and issue receipts locally. All data syncs automatically when the connection returns, with zero loss of transactions.
