Online stores you own, set up properly

Products, checkout, shipping and tax set up on a platform in your name. Small stores from $8,500, larger catalogs as a custom build.

An online store has more moving parts than a regular website: products and options, checkout, shipping, tax, payouts, and the emails customers get after they buy. We set all of it up properly, on a platform where the store, the customer list and the money are yours.

What we set up

  • Your products, with photos, options like sizes and colors, and clear prices.
  • Checkout and payments through a trusted provider such as Shopify, Square or Stripe. Card details are handled by the payment provider, never stored on your site.
  • Shipping and tax rules that match how you actually deliver.
  • Order and customer emails that sound like your business.
  • Product and category pages built for search, so people can find what you sell.
  • Accessibility built into the code to WCAG 2.1 AA. E-commerce sites are the most common target of website accessibility lawsuits, making up about 70% of cases in UsableNet's 2025 data. More on that.
  • Everything in your name: the store account, the payment account, the domain.

What it costs

Your store Package Price Timeline
A small catalog alongside a business site Business Site $8,500 3–4 weeks
A large catalog, subscriptions or a custom checkout Custom Build $15,000+ 6–8 weeks

Platform and card-processing fees are charged by those providers directly, not by us. You'll get the exact scope and price in writing before anything starts.

Choosing a platform

We'll recommend a platform in your written scope based on what you sell and how you work:

  • Already selling somewhere? If you're on Shopify, Square, Etsy or similar, we'll either build from it or move you off it, whichever makes more sense.
  • A handful of products or services? Payment links or a buy button on a regular site can be simpler and cheaper to run than a full store.
  • Hundreds of products or complex options? A full e-commerce platform earns its monthly fee.

Frequently asked questions

Do you take a cut of my sales?

No. You pay the platform and payment provider their standard fees. We charge the fixed price in writing and nothing per sale.

Can I add and edit products myself?

Yes. Stores are set up so you can manage products, prices and orders yourself, and we walk you through it at handover.

Can you connect the store to my point-of-sale system?

Often, yes, especially if you already use Square or Shopify in person. Integrations like this are usually part of a Custom Build; we'll say which in your quote.
