Frequently Asked Questions About our Shopify Agency
What is a Shopify Agency?
A Shopify Agency is a certified team of experts that help brands build, customise, migrate, and grow online stores on Shopify and Shopify Plus. As an official Shopify Plus Partner agency, MM Shopy Devs handles everything from custom theme design to performance optimisation. Learn more about our Shopify Agency.
Why choose a certified Plus experts?

Can you work with Shopify 1.0 and 2.0 themes?
Of course! Whether it’s Shopify 1.0 or 2.0, our team of Shopify developers is highly experienced. The only exception would be if the theme was previously modified by someone inexperienced, leading to bugs and issues. However, rest assured that we will still offer you a solution. Check our Shopify theme customisation page for more details.
Can we use our own designers for the UX?
Yes, we don’t have in-house UX designers for this reason. Most of our clients prefer to choose a designer based on their style, so we don’t want to limit them. Our team will work together with your designer, ensuring everything follows Shopify standards and that, as a store owner, you’ll be able to manage everything easily.
How long does it take to launch a Shopify store?
Most standard Shopify store builds take 3–5 weeks from kickoff to launch. More complex or custom projects can vary. We’ll always provide a detailed timeline before starting.
Does your Shopify agency have a minimum project size requirement?
Simply put, we don’t. We understand that not all stores need the same amount of work every month and that sometimes urgent issues arise that can’t wait. The only thing we ask of our clients is to group tasks together during the month to avoid fragmenting the work.
How much does a Shopify project cost?
To provide a quote, we need all the details and a full understanding of the project, whether big or small. This approach reflects our commitment to trustworthiness, as we want to ensure we offer the correct solution to your problem. A few years ago, we wrote an interesting article on this topic, which we suggest you check out here.
Do you charge retainers?
We typically don’t ask for retainer contracts unless that’s what you need.
Do you work with Shopify Plus?
Yes, our team is highly experienced in Shopify Plus development.
Do you provide ongoing support after launch?
Yes, our agency offers ongoing support and maintenance plans. You’ll have direct access to our expert team for continuous improvements, troubleshooting, and growth advice, no ticket queues.
Do you offer marketing or SEO services?
We don’t, and for a good reason. Our agency focuses solely on “Shopify Development.” We firmly believe that specialization leads to better results, and that all-in-one solutions are often less effective. However, we do have a network of highly specialized experts we can recommend!
What regions do you serve?
We are based in Barcelona and London, but we work remotely with brands across Europe, the UK, and internationally.
Serving clients in the UK, Spain, Europe & Beyond
We set up our Shopify agency to operate entirely remotely so that we could hire the best minds, wherever they may be. We provide services to online retailers worldwide.
