Ecommerce development does not start with the design or with the platform. It starts with four questions: what you sell, who you sell it to, how you take payment, and who runs the store once it is live. Stores that do not sell were almost always built backwards: a nice template first, the question of how orders get handled second.

This guide covers what ecommerce development actually includes, how to choose the platform, what drives the timeline and the cost, and the mistakes we see most often when a store comes to us to be rebuilt.

What ecommerce development includes

  • Catalogue and structure. Categories organised around how your customer searches and buys, not around how your warehouse is organised. Every category and every product is a page that can show up in Google, if it has text of its own.
  • Checkout and payments. The payment processor, taxes, shipping costs and what happens when a card is declined. It is the part where design shows least and money is lost most.
  • Operations. Inventory, orders, returns and the automatic confirmation and shipping emails. If the store does not connect to how your team works, someone ends up copying orders by hand.
  • Measurement. Knowing which campaign, which search or which email produced each sale. Without it, every budget decision is a guess.
  • Mobile and speed. Most visits to a store arrive from a phone. A store that loads slowly or breaks on the last step loses the most expensive sale there is: the one that had already been decided.

Which platform to choose

For most stores the decision is between three options, and each one keeps a different set of decisions for itself:

  • Shopify handles payments, taxes, fraud and hosting in one place. It charges a percentage if you use a different payment processor, and the checkout follows its rules. It is the fastest route to selling physical products.
  • WooCommerce lives inside WordPress: the data, the customer list and the purchase rules are yours. It is worth it when you need pricing by customer group, subscriptions with conditions, or a checkout that is not standard.
  • Webflow works when the store is secondary: a few products alongside a site where design and content do the work. It has clear limits on catalogue size, currency and subscriptions.

Below roughly 100 orders a month, Shopify usually costs less to run once you count hosting, maintenance and hours. Above that, and with any requirement that is not standard, WooCommerce tends to win. We go into it in depth in the platform guide and in Webflow vs Shopify.

What drives the timeline and the cost

Two stores on the same platform can take very different amounts of time. What moves the project is not the design, it is five things:

  1. The number of products and variants that have to be loaded, photographed and described.
  2. The integrations: inventory, invoicing, shipping, marketplaces or an internal system.
  3. Custom theme or adapted template. A template gets you live quickly; a design that looks like nothing else takes more work.
  4. The migration, if you already have a store: products, customers, orders and every URL that shows up in Google today.
  5. The costs that continue after launch: the plan, the monthly apps and the percentage per sale. Work them out as a proportion of your expected revenue before choosing, not in month nine.

The mistakes we see most

  • A checkout that breaks on mobile. Franco's Pasta came to us with a site that did not adapt to phones and a broken checkout. We rebuilt it on Shopify.
  • A catalogue organised the way the company thinks. Marie Birdie, golf apparel for young players, needed a catalogue organised around how golfers actually shop.
  • A homepage that does not explain why the product is worth its price. Dixie Grace was selling a premium snack from a homepage that looked amateur.
  • The store and the packaging designed separately. At MUZE, the product had to work as a thumbnail before it worked on a shelf, so the packaging and the store were designed as one system.
  • Not knowing which campaign made the sale. A store without measurement ends up investing in whatever makes the most noise, not in whatever sells the most.

Ecommerce SEO from day one

Stores that show up in Google have one thing in common: they were planned around searches before they were designed. Every category answers a specific search, every product has a description of its own instead of the manufacturer's, the URLs are clean, and product structured data tells Google the price and the availability. If the store is coming from another platform, every old address has its new one assigned before launch, so nothing that was already ranking gets lost.

How to start

  1. Write in one line what you sell and to whom. If it does not fit in one line, the store will not explain it either.
  2. Count your products and variants, today and in two years.
  3. Write down how you charge and how you ship, and any rule that is not standard.
  4. Decide who will run the store day to day.
  5. Then, and only then, choose the platform.

We build stores on Shopify and WooCommerce, and we tell you which one suits your business rather than which one we prefer to sell. If you are about to start or about to rebuild your online store, tell us what you sell and how.
