The basics

What is e-commerce development?

E-commerce development is the design and build of an online store: product pages, cart and checkout, payments, shipping and tax rules, and the admin tools you use to manage products, stock and orders.

The platform matters less than the details that make people buy: fast mobile pages, clear product information, trusted payment options and a short checkout. This guide covers the platforms we build on, the types of online business, what affects cost and timeline, and how a store keeps growing after launch.

Platform deep dive

The platforms we build on, explained.

Each platform has its own page with process, examples and FAQs. Payments on every platform are handled through secure payment gateway integration.

WooCommerce development

Best when content and ownership matter

WooCommerce turns WordPress into a full online store. You own the code and data, can add almost any feature through extensions or custom code, and get WordPress’s strengths in blogging and SEO. It suits stores that sell alongside lots of content, need custom pricing or shipping rules, or want to avoid monthly platform fees.

  • Full ownership, no platform lock-in
  • Huge choice of payment, shipping and marketing extensions
  • Needs good hosting and regular updates

Shopify development

Best for fast launch and easy running

Shopify is a hosted platform: security, hosting and checkout are handled for you, so you can launch quickly and run the store with little technical upkeep. We design custom Shopify themes, set up apps, and migrate products and customers from other platforms.

  • Fast to launch, reliable hosted checkout
  • Large app store for extra features
  • Monthly plan, app and transaction fees

Shopify development ›

Laravel e-commerce

Best for custom rules and integrations

For B2B portals, complex catalogues or unusual workflows, we build stores in Laravel. Every rule, screen and integration is built for your business, with no plugin limits, and it connects directly to ERP, inventory or accounting systems.

  • Unlimited flexibility and performance tuning
  • Clean integration with your existing systems
  • Longer build and higher upfront cost

Laravel e-commerce ›

Multi-vendor marketplace

Best for platforms with many sellers

A marketplace lets many sellers list products while you manage the platform and earn commission. We build seller onboarding, dashboards, commission rules, split payouts, reviews and moderation tools.

  • Revenue from commission and seller fees
  • Seller dashboards and automated payouts
  • Needs clear rules and active moderation

Why stores lose sales

Most carts are abandoned. Many reasons are fixable.

70.22%

of online shopping carts are abandoned on average

Average across 50 studies. Many of the reasons below are fixable with better store design and checkout.

Source: Baymard Institute, cart abandonment rate statistics (page updated 22 Sep 2025). Reasons from US online shoppers, excluding "just browsing".

Too long / complicated checkout17%
Website had errors / crashed17%

Couldn't see total order cost up-front12%

Highlighted reasons are ones good store and checkout design directly addresses.

Anatomy of a product page

What makes a product page convert.

  1. 1

    Large, zoomable product images

    Multiple angles and zoom help shoppers judge the product without touching it.

  2. 2

    Clear title and reviews

    Star ratings and review counts near the title build trust quickly.

  3. 3

    Price with total costs visible

    Showing shipping and taxes early tackles the top abandonment reason: unexpected extra costs.

  4. 4

    Simple variant choice

    Size and colour options that are easy to tap, with stock shown.

  5. 5

    One clear add-to-cart button

    A single, high-contrast action, visible without scrolling on mobile.

  6. 6

    Trust and delivery info

    Secure payment, returns policy and delivery time right beside the button.

  7. 7

    Real customer reviews

    Detailed reviews and photos answer questions before checkout.

Sample layout with illustrative content. Tap a number to see why it matters.

E-commerce FAQs.

Still unsure? Email info@web3matrix.com or message us on WhatsApp.

Which e-commerce platform is best for my business?
It depends on your products, budget, who manages the store and the features you need. WooCommerce suits content-rich stores, Shopify suits fast launches with easy management, and Laravel suits unique requirements. Use the platform picker above, then we confirm on a free call.
Can you move my existing store to a new platform?
Yes. We migrate products, customers and orders where the platforms allow, set up redirects to protect your search rankings and test everything before switching over.
Do you set up payments and shipping?
Yes. We connect payment gateways, configure shipping rates and tax rules for the regions you sell to, and test real orders before launch.
Can I manage products and orders myself?
Yes. Every store comes with an admin area for products, stock, orders and customers, and we train your team after launch.
Can you add AI features to my store?
Yes. We can add search that understands natural questions, product recommendations and AI-assisted product descriptions reviewed by people. Each AI feature has a running cost we explain first.
Do you build stores for international businesses?
Yes. Our team in Dhaka, Bangladesh works with clients in the UK, the USA, Canada and Europe, and welcomes projects from Australia, Japan, South Korea and other markets. We have a UK address in London. Projects run remotely with video calls, shared design reviews and a private staging store.
How much does an e-commerce website cost?
It depends on the platform, number of products, custom design and integrations. A starter store costs far less than a B2B portal or marketplace. Use our cost estimator or see pricing.
How long does it take to build an online store?
Typically 3 to 5 weeks for a starter store, 5 to 8 weeks for a growing store, and 10 weeks or more for B2B portals and marketplaces, depending on product data and feedback.
Is my online store secure?
Yes. We use SSL, trusted payment gateways that handle card data so it never touches your server, strong admin logins, backups and ongoing updates.
Will my store rank on Google?
We build SEO in from the start: fast pages, clean category structure, product structured data and an XML sitemap. Ongoing SEO and content help it climb further.
Can you connect my store to inventory, accounting or POS systems?
In most cases, yes. We connect stores to inventory, accounting, shipping and point-of-sale systems through their APIs or existing integrations, after checking what your systems support.
