Every agency claims to be a Shopify expert. The Shopify Partner directory lists over 1,000 agencies. Most of them will show you polished portfolios, respond quickly to your inquiry, and tell you exactly what you want to hear. The ones who can actually execute are a much smaller group.
Key Takeaways
- Ask specifically who will build your store — not who will manage the project.
- Case studies with conversion metrics are worth ten times more than design screenshots.
- Shopify Partner tier matters, but it doesn’t guarantee quality — it’s a starting filter, not a final answer.
- Budget signals a lot: quotes under $3,000 for a custom Shopify build usually mean template work, offshore labor, or both.
Define What You Actually Need Before You Talk to Any Shopify Agency
Most agency evaluation failures start here. You contact agencies without a clear brief, let them frame the conversation, and end up evaluating their sales skills instead of their execution capabilities.
Spend one hour writing down: what your store needs to do, what your current platform is (if migrating), how many products you have, what your revenue target is, and what’s wrong with your current setup. This brief changes the entire dynamic of Shopify agency conversations.
New Build vs. Migration vs. Ongoing Optimization — Different Skill Sets
A Shopify agency that’s excellent at new store builds may not be the right fit for a complex migration from Magento. An agency with strong CRO and growth optimization skills may be a better ongoing partner than a better initial builder. These are different disciplines.
Know which you need before asking a Shopify agency to quote.
Shopify vs. Shopify Plus: Does Your Project Need Plus Expertise?
If your store is doing over $1M/year in revenue or you need checkout extensibility (custom checkout UI, checkout scripts), you’re in Shopify Plus territory. Not all Shopify agencies have Plus experience. Ask specifically.
The 10 Questions to Ask Every Shopify Agency
These questions are designed to produce answers that agencies can’t fake.
1. Who Will Actually Build My Store — and Can I Meet Them?
This is the most important question when choosing a Shopify agency. Many agencies sell with senior people and build with juniors. The person who pitches you understands your business. The person who builds your store may have done it for 8 months.
Ask to meet the developer assigned to your project before signing. Ask about their Shopify experience specifically — how many stores have they built, what’s the most complex thing they’ve done in Liquid, have they done custom section development.
If the Shopify agency says they can’t introduce you to the developer until after you’ve signed, that’s a signal.
2. Show Me Conversion Metrics from Stores You’ve Built, Not Design Screenshots
Design screenshots prove design taste. They don’t prove business outcomes. Ask for stores they’ve built that you can visit, and ask what conversion rate those stores are hitting.
Good Shopify agencies track post-launch performance. They know what happened to the stores they built. They’re proud of the outcomes, not just the aesthetics.
3. What Happens After Launch?
Find out exactly what post-launch support is included in the project quote. Is there a warranty period? For how long? What counts as a bug versus a change request? Who do you contact, and what’s the response time?
Agencies that disappear after launch are a known pattern. Ask specifically what the handoff looks like and what you’ll need to manage yourself from day one.
4. How Do You Handle Scope Changes and Overages?
Every project encounters scope changes. How does the Shopify agency price them? Do they use change orders? Do they have a transparent hourly rate for out-of-scope work? Do they require approval before billing for additions?
An agency that can’t answer this clearly will surprise you with invoices later.
5. What’s Your Shopify Partner Tier and How Many Stores Have You Launched This Year?
Shopify Partner tiers (Associate, Plus Partner) require meeting revenue and project volume thresholds. Tier doesn’t guarantee quality, but it’s evidence of consistent project delivery. An agency claiming Shopify expertise that isn’t a registered Shopify Partner is a red flag.
Ask how many Shopify stores they’ve launched in the last 12 months. A credible agency specializing in Shopify should answer with at least 10–20.
Marcus spent three weeks talking to five Shopify agencies before choosing one. The winning agency wasn’t the cheapest or the most polished in their proposal. They were the ones who connected him with the developer before signing, showed him live stores with conversion data (one apparel brand at 3.8% conversion rate), and answered his overage question with a specific hourly rate ($125/hr) and an explicit change order process. He knew what he was buying. The project came in on budget and launched 2 days ahead of schedule.
6. Do You Work in Shopify Liquid, or Do You Use a Page Builder?
Some Shopify agencies build with Shopify section and block architecture natively. Others rely heavily on tools like PageFly or GemPages — drag-and-drop page builders that run as apps on top of Shopify.
Page builders add JavaScript to every page load, slow your store, and create maintenance dependency on the app. If the app shuts down or prices change, your page designs break. Ask directly: do you build in Liquid or in a page builder app?
7. Who Owns the Code and Store Credentials After Launch?
You should own everything. The Shopify account should be in your name. Any custom theme code should be delivered to you. No proprietary systems, no ongoing license fees for assets they built.
Some Shopify agencies structure ownership to create dependency. Ask this question before signing, and get the answer in the contract.
8. Can You Show Me a Store You Migrated, and What Happened to Its SEO Traffic?
Migration-specific Shopify agencies should be able to walk you through a migration project with pre- and post-migration traffic data. If they can’t, either they haven’t done many migrations or they don’t track outcomes.
9. What’s Your Policy If the Project Goes Over Timeline?
Timeline overruns are common. What happens when they occur? Does the Shopify agency charge you for the extra time? Do they absorb it? Is there a cap on timeline extensions before penalties kick in?
Knowing this upfront tells you a lot about how the agency manages risk.
10. What Won’t You Do for Me?
Agencies that are honest about their scope of work are more trustworthy than agencies that claim to do everything. A Shopify build agency that says “we don’t run Google Ads — we’d refer you out for that” is more credible than one that claims a full-stack marketing offering.
How to Evaluate What Shopify Agencies Show You
How to Read a Case Study for Real Results vs. Vanity Metrics
Look for: conversion rate before and after, revenue growth, page speed scores, organic traffic change. These are outcomes.
Discount: design awards, “500% increase in social followers,” vague claims about “improved user experience,” before/after screenshots without performance data.
Red Flags in Shopify Agency Portfolios
- No live stores you can actually visit and shop
- Only design screenshots, no functional demos
- Case studies from 3+ years ago (recent work should be the centerpiece)
- No mention of conversion outcomes
- Portfolio that looks suspiciously polished compared to what agencies their size typically produce (licensed stock imagery, fake client logos)

How to Spot Underpriced Quotes (and What They Signal)
A quote under $2,000 for a custom Shopify build is almost always one of three things:
- A template install dressed up as custom work
- Offshore labor with thin project management
- A scope that excludes items you think are included (SEO setup, redirects, app configuration, etc.)
Ask what’s explicitly not included. The exclusion list is as important as the inclusion list.
The Checklist Before You Sign With a Shopify Agency
Contract Terms to Insist On
Before signing any Shopify agency contract:
- Milestone payments, not 100% upfront
- Specific deliverables at each milestone, not just phase names
- Defined timeline with completion criteria
- Change order process documented and priced
- Code ownership — all custom code transfers to you
- Post-launch support window with duration and response time SLA
Ownership of Code, Data, and Domain
Your Shopify account: in your name, you are the owner. Your domain: registered in your name, not the agency’s. Custom theme files: delivered to you, no ongoing license. If a Shopify agency has you sign over any of these things, walk away.

Conclusion
Choosing a Shopify agency is a due diligence exercise, not a vibe check. The agencies that look the best in proposals aren’t always the ones that build the best stores.
Four things separate reliable Shopify agencies from pitch merchants:
- They can introduce you to the person who will build your store before you sign
- They have conversion data from stores they’ve built, not just design screenshots
- They have a clear, documented process for scope changes
- They hand over full ownership of everything after launch
Ask the hard questions early. The right Shopify agency won’t be annoyed by them — they’ll have ready answers. Once you’ve chosen a partner, understanding what to expect from a Shopify store build sets the right expectations for the project ahead.

Frequently Asked Questions
What is a Shopify Partner and does it matter?
A Shopify Partner is an agency or developer registered in Shopify’s partner program, which requires meeting activity and revenue thresholds. Partner status signals consistent project delivery but doesn’t guarantee quality. It’s a starting filter — rule out non-partners, but don’t stop evaluating there.
How much should a custom Shopify build cost in 2026?
A legitimately custom Shopify build — custom sections, full configuration, analytics setup, app stack — starts at $5,000 and goes up to $15,000 for most small-to-medium stores. Shopify Plus builds start higher. Quotes significantly below $3,500 for “custom” work usually indicate template work or thin scope.
Should I hire a local Shopify agency or does location not matter?
Location matters less than it did five years ago. The relevant factors are communication timezone overlap (useful but not essential), portfolio quality, and process clarity. A well-run remote Shopify agency outperforms a poorly-run local one every time.
What’s the difference between a Shopify developer and a Shopify agency?
A Shopify developer is typically one person: they write code, build themes, or configure apps. A Shopify agency is a team: they combine design, development, project management, and often ongoing support. For simple builds or migrations, a developer may be sufficient. For complex builds with custom design and post-launch support needs, an agency structure offers more coverage.
How long should a Shopify project take from kickoff to launch?
A basic Shopify store build takes 10–14 business days. A custom build takes 3–4 weeks. Complex builds with custom functionality or large product catalogs take 6–10 weeks. Migrations add a pre-migration audit phase of 1–2 weeks. Timelines shorter than these are generally achieved by cutting scope, not by working faster.
