How to Choose the Right Shopify Agency for Your Business in 2026
· By Twisty Designs
Hiring a Shopify agency is one of the most important decisions a growing eCommerce brand can make.
The right agency does not just build you a store. They understand your business, your customers, and your goals. They bring expertise you do not have in-house. They save you months of trial and error. And they build something that actually performs, not just something that looks good in a presentation.
The wrong agency, on the other hand, can cost you far more than their fee. Missed deadlines, poor quality work, stores that look great but do not convert, and developers who disappear after launch are all more common than they should be.
So how do you tell the difference before you commit? Here is exactly what to look for.
Look at Their Portfolio With a Critical Eye
Every agency will show you their best work. Your job is to look beyond the aesthetics and ask harder questions.
Do the stores in their portfolio actually look like they would sell? A beautiful homepage means very little if the product pages are weak, the navigation is confusing, or the checkout is not optimised. Look at the full journey, not just the hero image.
Are the stores they have built relevant to your business? An agency that specialises in fashion stores may not be the right fit for a personalised gifts brand. Look for work that is similar in product type, audience, or business model to yours.
Can they show you results, not just design? The best agencies can point to stores they built and tell you what happened after launch: conversion rate improvements, revenue growth, reduced bounce rates. If an agency can only show you how things look and not how they perform, that tells you something important.
Check Their Expertise in the Areas You Actually Need
Not all Shopify agencies are the same. Some specialise in design. Some in development. Some in conversion rate optimisation. Some in specific apps or integrations. And some, like Twisty Designs, bring all of these capabilities together in one team.
Before you shortlist any agency, be clear on what you actually need. If you are building a store that relies heavily on product personalisation, you need an agency with proven experience in personalisation tools, not just general Shopify development. If conversion rate optimisation is your priority, look for agencies that talk about strategy and data, not just visual design.
Ask specifically about the tools and platforms relevant to your business. Ask how many stores they have built using those tools. Ask what challenges they have encountered and how they solved them. The answers will quickly reveal whether their expertise is genuine or surface-level.
Ask About Their Process
A good agency has a clear, well-defined process for every project. They can tell you exactly what happens from the first call to the final launch, and what your involvement looks like at each stage.
Ask how they handle discovery and strategy before design begins. Ask how many rounds of revisions are included. Ask how they communicate throughout the project and how frequently you will receive updates. Ask what happens if the project runs over the original timeline or scope.
Agencies that give vague answers to these questions are often operating without a proper process, which means your project is likely to be chaotic, delayed, or both. Agencies that answer clearly and confidently have done this many times before and know how to deliver.
Read Reviews and Talk to Past Clients
What an agency says about themselves is less important than what their clients say about them. Look for reviews on Google, Clutch, or the Shopify Partner directory. Read them carefully, not just the star rating. Pay attention to what clients say about communication, timeline, quality of work, and what happened when problems arose.
If possible, ask the agency for references you can contact directly. A brief conversation with a past client will tell you more than any portfolio or case study. Ask them what the agency did well, what they would have done differently, and whether they would hire them again.
An agency that is confident in the quality of their work will have no hesitation in connecting you with past clients.
Understand How They Think About Growth
The best Shopify agencies do not just build stores and move on. They think about your store as a growth engine and bring a strategic perspective to every decision they make.
They ask about your customers before they talk about design. They want to understand your average order value, your conversion rate, where your traffic comes from, and what your biggest challenges are. They make recommendations based on what will actually move the business forward, not just what will look impressive in their portfolio.
When you are evaluating agencies, pay attention to whether they ask smart questions about your business or go straight to talking about what they can build. The ones who ask questions first are the ones who will build something that actually works for you.
Consider the Ongoing Relationship
Launching a Shopify store is not the end of the journey. It is the beginning. The best agency relationships are ongoing partnerships, not one-time projects.
After launch, you will need updates, optimisations, new features, and ongoing support. You will want someone who knows your store inside and out, who you can call when something breaks, and who proactively brings you ideas for improving performance over time.
Ask any agency you are considering what their post-launch support looks like. Do they offer maintenance plans? Do they have a team available to make changes quickly? Are they interested in a long-term relationship or just closing the next project?
The answer will tell you a lot about whether they see you as a client or a transaction.

Final Thoughts
Choosing the right Shopify agency comes down to three things: proven expertise in what you actually need, a clear and professional process, and a genuine interest in your business success rather than just delivering a project.
Take your time. Ask the right questions. Look beyond the portfolio. And choose an agency that you feel confident will still be there for you six months after your store goes live.
The right partner makes everything easier. The wrong one makes everything harder. Do the work upfront to get it right.
