Shopify store design & development
A custom Shopify store your team edits without a developer
For brands that have outgrown a bought theme. We design and build custom Shopify and Shopify Plus stores from a blank theme: the layouts, the product page, the sections your team will edit, and the integrations behind them. Enibbana, Spoon and Better Health run on stores we built.
Happy clients
You get a written scope with a fixed price before we start, and projects start within three to five business days. The people on the first call are the people who ship the launch. A staging store goes up early so you can click through pages as they land, and you hear from us at least every 48 hours.
We have worked with more than 40 Shopify Plus merchants and app owners, and we write apps as well as themes. The mix-and-match bundle creator we built for emma&noah on Shopify Plus raised their average order value by 61%. Features like that get designed into the theme from the start.
What a store build includes
- 01Design from your catalogueOur designer lays out the home, collection, product and cart pages around your real products and photography. You sign off the designs before any Liquid is written.
- 02Online Store 2.0 themeA theme built on Online Store 2.0 sections and metafields, so your team adds a landing page, swaps a banner or edits a size guide in the theme editor on their own.
- 03Product page built for phonesImages, variant selector, price and add-to-cart placed where a thumb reaches them. We test every template on a phone and check Core Web Vitals before launch.
- 04Integrations and appsERP, 3PL and CRM connections built as part of the scope, plus a custom app when an off-the-shelf one does not fit. We built emma&noah’s bundle creator and Ryzon’s bundle app this way.
- 05Staging store and launchYou click through a staging store while we build, so feedback happens on the real thing. Launch goes on a day you choose, with your previous theme kept in the theme library.
- 06The same senior teamSenior engineers and a designer, and the people from the first call stay on the project to launch. Updates at least every 48 hours in one shared Slack channel, and a weekly call to walk through progress.
So Called Crew
Four steps, and you can see every one of them
- 01A 30-minute callWe look through your store before the call and come with questions about what is slowing it down, so the time goes on your store and not on a pitch.
- 02A written scope with a fixed priceWhat we will build, what it costs and when it starts, on one page. Most projects start within 3–5 business days of you saying yes.
- 03Build in the openA shared Slack channel, a staging store you can click through at any point, an update at least every 48 hours and a call every week.
- 04Launch, then stay closeWe launch, watch the first weeks of data and fix what the data says to fix. Most clients keep us on for the next thing.
