Frequently Asked Questions About Shopify Agencies

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.

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.

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.

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.

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.

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

We typically don’t ask for retainer contracts unless that’s what you need.

Yes, our team is highly experienced in Shopify Plus development.

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.

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!

We are based in Barcelona and London, but we work remotely with brands across Europe, the UK, and internationally.
