You have settled on Shopify for your online store, now you need someone to build it. Whether you are building your first online store or migrating from another eCommerce platform to Shopify, choosing the right partner matters about as much as the platform decision.
Look for these key things: deep Shopify knowledge, design that goes past theme adjustments, the ability to integrate your store with the systems you already run, and ongoing support after launch. Shopify’s popularity means there is no shortage of freelancers and agencies to choose from. The problem becomes trying to wade through a pool of options to find a partner that understands what you need. Think of it like picking a hairdresser. You walk in with a photo of what you want: A good one tells you whether it’ll actually work for you, asks the right questions, collaborates on a style that elevates your look, and then executes it; a bad one just says yes.
Here’s how to choose the right Shopify development agency for your build.
Define your scope before you shop
Before you start shopping around for a partner, it’s helpful to internally define your scope so you know what the job involves.
Here's what a Shopify build can include:
- Visual design and content production - Brand-aligned design and page content.
- Theme work - Customizing an existing theme, building a custom theme from scratch, or going headless.
- Data migration - Products, variants, customers, historical orders, and SEO redirects.
- Integrations - Connecting Shopify to your ERP, warehouse management system, shipping platform, email tool, and accounting software.
- Custom app development - When Shopify's native features and the third-party app ecosystem can't support how you operate, you need to build the gap-filler.
- Ongoing optimization and support - Monitoring, enhancements, new features, and keeping the store stable as the business changes.
Your Shopify partner will do a deeper scoping, but having an initial sense of what you need helps cut through the noise and identify what level of expertise you're shopping for. If you need a simple website refresh, a smaller design-focused agency will likely serve you well. If you’re on or moving to Shopify Plus, with multi-store requirements, advanced customizations, or ERP integrations, look for a more full-service, certified Shopify Plus partner.
Look at factors that reflect their expertise
Design & user experience (UX/UI)
UX/UI decisions can often make or break a website. A visually stunning website is not enough. If the site is not designed to match your customer journey and feel intuitive to the buyer, it won’t lead to conversions. This can be hard to gauge during the review process because most agencies have beautiful designs in their portfolio. But, during conversations, check if the agency prioritizes questions to understand your buyer journey, pain points, and the overall goal of your site.
Another thing to note is that Shopify is a very theme-based eCommerce platform, so designing layouts or styles outside the scope of the theme requires custom development. Look for examples that show the agency has the capability to build custom designs that extend beyond the limits of a theme.
Shopify integrations with ERP or other systems
A Shopify agency might be able to design a beautiful storefront, but they may lack the expertise to build system integrations that connect your ERP, accounting software, warehouse management, or other tools to your site. This becomes a problem if orders need to reach an accounting system, inventory needs to stay accurate across warehouses, or your finance team needs real-time reporting.
We ran into this with MAGNA-TILES®, a global toy manufacturer whose ERP, Shopify, and warehouse systems weren’t talking to each other after a Dynamics 365 Business Central implementation fell short. The gaps were slowing fulfillment and making reporting difficult. We connected Shopify to Business Central to automate stock updates and fulfillment tracking, and built a custom Logiwa WMS integration that eliminated manual reconciliation between systems.
When you’re interviewing agencies, look at their integration expertise and portfolio. Ask what broke and how they handled it, so you know they have hands-on experience with building these integrations and navigating any challenges that arise during the process. This also matters if you are re-platforming because a lot of third-party integrations might need to be recreated in Shopify.
SEO and AI visibility
SEO and AI search optimization should not be an afterthought, especially if you are re-platforming. When you move to Shopify from a different platform like WooCommerce, SEO takes a hit if your URL structures, redirects, metadata, and other product content are not configured properly. So, make sure the agency understands SEO and bakes this into their process from the beginning.
Look at how they approach the discovery process & how well they communicate
The questions an agency asks before quoting are the best available proxy for how they’ll run the project.
Serious discovery digs into things that actually determine effort and risk: how many products and variants; whether you use bundles or configurable products; how many customers; how much data needs to be pulled in; whether you have tiered, member, or wholesale pricing; how shipping works; which plugins you depend on; what your payment setup looks like; and what your highest-traffic pages are.
A more thorough proposal process winds up being more consistent and predictable in the long run.
This is also a good time to evaluate how the agency communicates. Are they forthcoming about cost and the level of effort? Are they responsive and willing to listen? Are they collaborative?
How they behave during scoping and discovery is the clearest preview you'll get of the working relationship. Beyond an expert partner, you’re also choosing who you'll be on calls with for the next several weeks. So, make sure they’re the right fit for your culture and how your team works.
See what their post-launch support looks like
Launching a store is only one half of the development process. Then comes the post-launch support and care.
The first few weeks after launch are critical because this is when users need the most support or issues may arise with the site that need to be triaged. Beyond that, you also want the agency to be available for ongoing optimizations, technical fixes, or to support user adoption as Shopify drops updates or your business evolves. See what kind of support and maintenance plans are offered, and get clear on the structure – retainer, block of hours, or ad hoc – along with response commitments.
Choosing well
The agencies that seem similar on a homepage separate quickly once you know what your project demands. Get clear on your scope first, then look at the factors like design depth if conversion is your problem; integration experience if your store needs to connect to other systems; SEO if search majorly contributes to your revenue; and support if you need a long-term partner.
Then watch how they handle discovery, and ask for a reference from a project that with your kind of complexity. If an agency’s Shopify portfolio is newer, it’s worth evaluating their adjacent eCommerce work on comparable platforms. Many of these capabilities transfer more reliably and can speak to an agency's expertise better than platform tenure.
