What is at stake
On an established store, the risk is in the switch over.
A new Shopify store should lift conversion, speed and rankings. When a rebuild goes wrong, it is almost always in one of three places, and each one costs money from the first day.
Revenue on day one
Checkout, payments, tax, shipping and discount rules that worked on the old platform and quietly fail on the new one, found by customers rather than by testing.
Rankings and traffic
Years of search visibility lost because URLs were not mapped and redirected, so organic revenue drops the week the new store goes live.
Stock, pricing and orders
An ERP or warehouse sync that breaks under real volume, showing the wrong stock or trade prices and sending orders nowhere.
Every Rococo build is planned around those three, with a director leading it and a sign off at every stage, so the switch over is the least eventful day of the project.
The build map
How a Shopify build runs, from first call to launch.
Every project follows the same five stages. You sign off each one before the next starts, so nothing reaches your customers that you have not already seen.
- 1
Scope
Goals, customers, catalogue and every integration mapped, ending in a fixed proposal and timeline.
You sign offScope and proposal
- 2
Design
Conversion-led design for the pages that sell, from home and collections to product and cart, mobile first.
You sign offDesigns on every device

Build and integrate
Clean Online Store 2.0 code, Shopify Functions where logic is needed, and your ERP, stock and marketing systems connected.
You sign offThe staging store

Test and migrate
Products, customers and order history moved, every redirect mapped and test orders run end to end.

Launch and grow

You sign offGo live
Most builds take six to twelve weeks. Shopify Plus, migrations and heavily integrated projects take longer, and the proposal gives you the timeline before any work starts.
Shopify development services
What a Shopify development company should build for you.
Shopify website development, design, migration and integration from one senior team in Arundel. Most projects combine several of these, scoped together in one proposal.
Shopify website design
Custom Shopify website design for every template, built around how your customers buy and signed off on mobile and desktop before a line of code is written.
Store builds and redesigns
New Shopify and Shopify Plus stores, or existing stores rebuilt for speed and conversion, on Online Store 2.0 sections your team can edit without a developer.
Migrations to Shopify
From WooCommerce, Magento, BigCommerce or a custom build, with products, customers and orders moved and every URL redirected. More on our Shopify migration work.
Shopify Plus and headless
Checkout extensibility, expansion stores, automation and headless builds for brands at volume. See our Shopify Plus agency page.
ERP, B2B and integrations
Stock, orders and trade pricing flowing between Shopify and Business Central, Sage, Brightpearl or Unleashed, with trade accounts and catalogues for B2B.
Custom apps and Shopify Functions
Discount, shipping, payment and checkout logic built the supported way, replacing old Scripts and checkout.liquid, by a team that publishes its own apps.
Talk your project through with Matt, who leads every build, or Jake.

Your Shopify developers
Shopify experts, with a director on every build.
A director runs your build from the first workshop to launch day, and the same people look after the store once it is live.
- Matthew Jones, technical director. Makes the platform decisions, oversees every build and flags technical risk early, before it reaches a launch or day to day trading.
- Jake Boase, director. Sets the design direction and makes sure the store is built around the way it will be marketed.
- Our own Shopify developers and designers. Every template, integration and page is designed and built by our team in Arundel, West Sussex. None of the build is outsourced.
- App developers as well as store builders. Our own Shopify App Store apps mean we know Shopify’s APIs and app review process from the inside.
- Marketing after launch. GA4, Klaviyo and Google Merchant Center are set up before launch, so our Shopify marketing team can start growing the store from day one.

“Rococo Digital delivered a website that has transformed our brand presence. It’s fast, modern, and built to scale with our business.”

- Shopify covers most growing brands, with hosting, security and checkout handled for you.
- Shopify Plus makes sense at volume, or when you need checkout extensibility, B2B at scale or several expansion stores. Read Shopify vs Shopify Plus.
- WooCommerce can suit brands that want full control and no platform fee. We build on both, so the advice is not tied to one. Read Shopify vs WooCommerce.
Not sure yet? Our Shopify consultants can help you decide before you commit to a build.
Who this suits
- Established retailers replatforming from WooCommerce, Magento or a custom build, where losing rankings or a day of trading is not an option.
- B2B and wholesale businesses that need trade accounts, pricing and ERP integration in the same store as retail.
- Shopify brands at scale whose theme and app stack can no longer keep up with the catalogue, the traffic or the team.
- Not yet a fit: a brand new store that just needs a theme set up. A freelancer or Shopify’s own setup help will cost you less, and we will say so.
Works alongside
The store is the start, not the finish.
A Shopify build earns its keep when people find it, buy from it and come back. These are the services that do that, all run by the same Shopify agency team.

Shopify development questions.
The questions brands ask us most before hiring a Shopify development agency. If yours is not here, ask it on the call.
A Shopify development agency designs, builds, migrates and supports Shopify and Shopify Plus stores: the theme and templates, custom apps and Shopify Functions, integrations with ERP and stock systems, and the migration from another platform. At Rococo it also means joining the store up with SEO, paid media, email and CRO, so it is built to grow rather than just go live.
Shopify builds and migrations with us start from £20,000. Shopify Plus, B2B and heavily integrated projects cost more, depending on the number of templates, integrations and how much data has to move. Each Shopify build gets a fixed price once we have scoped it. Shopify’s own plan fees sit on top of the build, and our Shopify fee calculator shows what those come to at your volume.
Most Shopify builds take six to twelve weeks, depending on design scope, the number of integrations and whether it is a fresh build or a migration. Shopify Plus, B2B and heavily customised projects take longer. The proposal sets out the timeline and every sign off point before any work starts.
Yes. We work as a Shopify design agency and a development company in one team. Our designers create every template, from the home page and collections to the product pages and cart, around how your customers shop. You sign off the designs on mobile and desktop before development starts, and the same team builds them, so nothing is lost between design and code.
Both. Most of our builds are custom themes on Online Store 2.0, designed around your brand and products. Where budget or timing calls for it, we can build on a well supported premium theme and customise it properly. Either way the sections are editable, so your team can build pages without a developer.
Yes, when the migration is planned properly. We move products, customers and order history from WooCommerce, Magento, BigCommerce or a custom build, redirect every URL with traffic or links to its new address, carry across titles and structured data, and watch rankings closely after launch. Our Shopify migration page covers the process in detail.
Yes. Shopify connects to most ERP, stock, warehouse and 3PL systems, through an existing connector or a custom integration. We have integrated Shopify with systems such as Microsoft Dynamics 365 Business Central, Sage, Brightpearl and Unleashed, and we map every integration before the build starts and test it with real orders before launch.
Standard Shopify covers most growing brands. Shopify Plus adds checkout extensibility, B2B at scale, expansion stores, more automation and higher API limits, and it makes sense once your volume or complexity justifies the cost. We build on both and will tell you which fits. Our Shopify vs Shopify Plus guide sets out the differences.
It depends on the business. Shopify is the faster, lower maintenance way to launch and scale, with hosting, security and checkout handled for you. WooCommerce gives you more control and no platform fee, but needs more hands on management. We build on both, so the advice is not tied to one platform. Our Shopify vs WooCommerce guide compares them in depth.
Yes. We publish our own apps on the Shopify App Store, including LimitField for order quantity limits and PagePort for content migration, so we know the platform’s APIs and limits first hand. When no existing app fits, we build a custom app or Shopify Function for your store instead.
Yes. We build for established retail and B2B businesses where the store has to carry trade accounts, pricing, ERP integration and a large catalogue. For Networks Centre we consolidated four websites into one platform with 18,700 SKUs, 6,061 customer accounts and a trade portal, with every legacy URL redirected.
Every build ends in a test and migrate stage before anything goes live. Test orders run end to end through checkout, payments, shipping and your integrations, every URL with traffic or links is redirected, and you sign off the results. After launch we watch rankings, tracking and orders closely, so anything unexpected is caught and fixed quickly.
Yes. We take on existing stores for redesigns, speed and Core Web Vitals work, new integrations, app clean ups, and moving old Shopify Scripts and checkout.liquid customisations to Shopify Functions and checkout extensions. We look through the store and its code before quoting any work.
Shopify ranks well when it is built properly. We plan URL structure, collections, schema, internal links and page speed from the first template, and our Shopify SEO team can grow organic traffic after launch.
Yes. After launch we offer retained Shopify development, maintenance, CRO and SEO, so the store keeps improving. Many clients stay with us for ongoing growth work rather than treating the build as a one off.
Ask who will write your code after the pitch, and whether they are senior. Ask how they keep a theme fast and editable without stacking apps, how they handle redirects and rankings in a migration, and whether speed and Core Web Vitals are in the scope or an extra. Then ask for named Shopify projects with numbers, and what happens after launch.
A freelance Shopify developer can be the right choice for small theme changes or a single feature. A full build or migration needs design, front end and back end development, data migration, SEO and testing, with cover when someone is away, and that is where a Shopify development agency earns its place. With us you get senior Shopify developers in house in the UK and a director on the project. For ongoing work, retained Shopify development starts from £4,000 a month.
You do. The store is set up in your own Shopify account, and the theme code, content and customer data all belong to you. Any custom app we build for you is scoped and agreed in the proposal. Change agency later and it all stays with you.
Matthew Jones, our technical director, makes the platform decisions and oversees every build, and Jake Boase leads the design direction and growth plan. Every template, integration and page is designed and built by our team in Arundel, West Sussex. None of the build is outsourced.
Yes. Rococo is a Shopify Partner and a certified Klaviyo Partner. As well as building Shopify and Shopify Plus stores, we publish apps on the Shopify App Store and run the marketing for many of the stores we build.
