Services
Everything your store needs, at every stage
Most agencies either build stores or grow them. We do both. A well built store is the foundation, and what happens after launch decides whether a brand scales. Our services cover the full journey.

Most projects are more than one service
Very few brands need a single thing. A typical project combines two or three of the services above, and the right combination depends on where you are starting rather than on what we would like to sell you. Three real examples:
- Migration
- Custom development
- UX
- Development
- CRO
- Migration
- Theme configuration
-
Hunza G moved from WooCommerce to Shopify, then rebuilt on a premium 2.0 theme with custom development.
-
Nude Project started as a build and became an ongoing partnership across UX, development and CRO, contributing to 65.2% yearly revenue growth.
-
Cassandra Goad migrated to Shopify on a 2.0 template configuration, without the cost of a bespoke build.
You do not need to work out the combination before you get in touch. Tell us where you are and we will map it with you.
Choose your service
Which service is right for you
Launching a new brand?
Start with a store setup, or a custom theme if you want fully bespoke.
Already selling and want more?
Look at CRO, a store audit, a redesign or theme customisation.
On another platform?
Start with a migration.
Need a specific feature or fix?
That is custom development.
Want a fresh look?
Website design or a store redesign.
Still unsure?
Talk to our team. We will recommend the right path honestly, and there is no minimum project size.
Process
How a project runs
Whichever service you choose, the shape of the work is the same.
-
01 Scope
We learn what you are trying to do and tell you honestly which service fits, including when a cheaper one would serve you better.
-
02 Plan
You get a fixed scope and a price before any work starts. No open-ended hourly billing.
-
03 Build
Work happens on a duplicate theme or a staging environment, never on your live store, and you review it on a preview link.
-
04 Launch, then whatever comes next
We publish, monitor and hand over. From there you can take it in-house, leave it, or continue with support or CRO. There is nothing to cancel.

Partners & stack
The apps we actually install
We test apps on real client stores before we recommend them. This is the shortlist we keep coming back to, with honest notes on what each one does well and where it stops. We mark clearly where we earn a referral, and several of the ones we recommend most pay us nothing.

A living collaboration across UX, development and CRO, with 65.2% yearly revenue growth.
Why us
No retainers, no minimum, no lock-in
Most agencies sell a fixed monthly contract, and you pay the same whether your store needed twenty hours that month or two. We do not work that way, on any of the services above.
- 01
No mandatory retainer
You pay for the work your store actually needs, when it needs it.
- 02
No minimum project size
From a single small fix to a full custom build. We only ask that small tasks are grouped so they are efficient.
- 03
Nothing to cancel
Projects end when the work ends. If you want to continue, you choose to start a new one.
Why brands choose MM Shopy Devs
- Certified Shopify Plus Partner.
- A senior team you work with directly, with no juniors and no outsourcing.
- One technical point of contact who owns your project.
- Specialists in fashion, lifestyle and luxury.
What we don't do
- SEO
- Paid media
- Content marketing
That is a deliberate choice. Agencies that sell everything rarely do all of it well, and you are better served by a specialist. We work alongside marketing and SEO teams on most projects, and we are happy to recommend people we trust from our network.
FAQs
Store setup, custom theme design and development, website design, migrations, conversion optimisation, audits and ongoing support. Everything needed to build and grow a store.
It depends on your stage - a new build, improving an existing store, migrating, design work or a specific feature. Tell us where you are and we will help you decide, including when a cheaper option would serve you better.
Yes, and most projects do. A migration usually comes with a build, and a build often continues into CRO or support. We will map the combination with you.
A store setup runs from £2,000 to £3,000, and a premium setup starts from £5,000. Everything else is scoped per project, because the range is genuinely wide and a headline number would mislead more than it helps. There is no minimum project size.
Yes. Support is flexible and on demand, with no long contracts.
No. We specialise in Shopify design, development and CRO, and we can recommend trusted specialists for the rest.
No. We take on everything from a single fix to a full build.
