E-commerce Websites : Complete Online Stores with Payment Integration & Inventory Management

By Mjini Digital — Top website developers in Nairobi. We build every kind of online store (WooCommerce, Shopify, Wix, Magento, custom headless ecommerce) with secure payment integration, inventory management, shipping, and SEO-first architecture.

Why an E-commerce Website Is a Must for Kenyan Businesses (Short Answer)

E-commerce is not “optional” — it’s a primary sales channel. Global online retail is growing rapidly (trillions in annual sales), and mobile shoppers now account for a majority of online purchases. In Kenya the number of online shoppers and digital payments continues to rise, creating a huge opportunity for retailers, FMCG brands, restaurants, and service providers to scale beyond physical borders.

What Mjini Digital Builds — Complete, Conversion-Focused Online Stores

We design and deliver end-to-end e-commerce websites tailored to your business and budget:

• Managed WooCommerce stores (ideal for WordPress sites wanting full control)

• Shopify stores (fast launch, great app ecosystem, scalable POS options)

• Wix & Squarespace stores (quick setup for small catalogues and local sellers)

• Magento / Adobe Commerce (for complex, enterprise stores)

• Headless e-commerce (React/Vue frontends + commerce backend for maximum speed & flexibility)

• Custom builds (APIs, integrations, marketplaces, and bespoke workflows)

Every store includes: mobile-first UX, SEO foundations, analytics, product feeds, shipping rules, tax rules, and inventory management connected to your sales channels.

Payment Integration — Local & Global: MPESA, Cards, Wallets, & More

A modern e-commerce site must accept the payment methods your customers already use. For Kenyan merchants we typically integrate:

• MPESA STK Push (seamless mobile payments)

• Visa / Mastercard & other card processors (via Stripe, PayPal, or local PSPs)

• Mobile wallets & buy-now-pay-later (BNPL) where appropriate

• Cash on delivery options and order-status automation

We ensure PCI-compliance where applicable and provide reporting that ties payments to inventory and accounting. With mobile commerce dominating many markets, having fast mobile checkout and wallet support is non-negotiable. (https://oyelabs.com)

Inventory Management & Omnichannel Sales

Selling across your website, social commerce, marketplaces, and physical stores requires a single source of truth for inventory. We build systems that:

• Sync stock levels across channels (website, marketplaces, in-store POS)

• Automate reorder alerts and low-stock workflows

• Provide bundle & variant management (sizes, colours, SKUs)

• Integrate with shipping partners and generate labels automatically

This reduces oversells, speeds fulfilment, and improves customer trust — a critical advantage in fast-growing e-commerce markets like Kenya. (Trade.gov)

Proven Business Impact — Real Data, Real ROI

Use of e-commerce drives measurable gains: higher conversion rates from targeted traffic, extended market reach, reduced overhead (compared with brick-and-mortar only), and more predictable cash flow via repeat customers and subscriptions.

Key market signals you should know:

• Global scale: Global e-commerce sales reached multitrillion dollar figures and continue to expand year-on-year — online retail is now a major share of global retail. (Shopify)

• Mobile dominance: A large and growing share of online purchases happen on mobile devices; optimizing for mobile checkout directly correlates with higher conversion. (https://oyelabs.com)

• Local uptake: Kenya’s e-commerce market has grown fast, with hundreds of millions in annual online retail revenue and rising user numbers — mobile money ecosystems (Mpesa) are a major enabler. (Trade.gov)

We design stores to capture this value immediately: faster product discovery, frictionless checkout, and targeted retention campaigns that lift lifetime value (LTV).

SEO, Content & Conversion — We Build Stores People Find and Buy From

A beautiful store is worthless if nobody finds it. Our approach combines technical SEO + content strategy + CRO:

• SEO foundations: schema.org markup, canonical tags, clean URLs, fast Core Web Vitals

• Keyword research for product pages and category pages (local search queries such as “buy shoes Nairobi”, “MPESA online store Kenya”)

• Optimized product copy, titles, meta descriptions, and structured data for rich snippets

• Link-building and marketplace feeds for discovery

• Email & SMS automation to recover carts and nurture customers

These elements are essential because search engines and marketplaces are primary discovery channels for buyers. We help you rank for the searches customers actually use.

Platforms & Pricing — Pick the Right Tool for the Job

Not every business needs enterprise software. We advise based on goals:

• Small catalog / fast go-to-market: Wix / Squarespace / Shopify Basic

• Growing brand / mid-size: Shopify Plus or WooCommerce with scalable hosting

• Large catalog / complex rules: Magento / headless commerce

• Custom marketplaces: Tailored microservices & API ecosystems

We also offer managed hosting, monitoring, and a support retainer so you never face downtime or security gaps.

Logistics, Fulfilment & Customer Experience

E-commerce success depends on speed and reliability:

• Integrate shipping APIs and local courier partners (automated label generation & tracking)

• Offer delivery windows, pickup options, and returns workflows

• Provide clear order tracking and post-purchase communication to reduce disputes

We design the experience so customers feel confident — that’s how you turn first-time buyers into repeat customers.

Security, Compliance & Payments Risk

We harden every store: HTTPS, WAF rules, secure tokens for payment flows, and regular security audits. If you accept cards, we help you meet PCI requirements; for MPESA and other local PSPs we implement secure callbacks and reconcile payments automatically.

Why Mjini Digital? Local Expertise, Global Standards

We combine deep local payments knowledge (MPESA, local PSPs) with global e-commerce best practices (performance, UX, SEO). Our clients get:

• Faster launch times and predictable costs

• Scalable architecture that grows with you
