How to Choose a Shopify Development Agency

Every Shopify agency's website says the same things. Certified, experienced, results-driven. None of it tells you whether they can build your store.
If you are not technical, the usual advice — "check their portfolio" — is hard to act on, because every portfolio looks good. Here is what to actually ask, and what the answers tell you.
Work out what you need first
The biggest cause of a bad outcome is hiring the wrong type of help, not hiring a bad agency. Three broadly different jobs:
| What you need | Who fits | Rough effort | |---|---|---| | Launch a straightforward store | A freelancer or small agency configuring a premium theme | Days to weeks | | Custom design, integrations, migration | A development agency | Weeks to months | | High-volume, ERP integration, multi-region | A Shopify Plus specialist | Months |
Paying for the third when you need the first is the most common way people overspend. Be honest about which you are.
Questions that reveal competence
"Can I see a store you built that is live now?"
Not a screenshot — a URL. Then open it on your phone and run PageSpeed Insights against a product page. If the stores they are proud of load slowly on mobile, that is what you will get.
Ask specifically: what did you build here, and what came with the theme? A lot of portfolio work is theme configuration presented as custom development. That is not dishonest in itself, but you should know what you are paying for.
"Who owns the store when we are finished?"
The only acceptable answer: you do, completely. That means the Shopify account is in your name and billing, and you hold the admin.
Walk away if an agency wants the store under their account, or is vague about the handover. Getting a store back from an agency that controls it is an expensive problem.
"What happens after launch?"
Launch is not the end. Ask:
- How long is the warranty on bugs after launch, and what counts as a bug versus a new request?
- What does ongoing support cost, and is it optional?
- Will I be trained to update products, prices and content myself?
An agency that expects to bill you for every text change has built something you cannot run.
"Which apps will this need, and what do they cost monthly?"
App subscriptions are the cost people forget. A build quoted at one number can carry hundreds a month in apps that were never mentioned.
A good agency will tell you which requirements need a paid app, which can be built into the theme, and the trade-off. A weaker one solves everything with apps because it is faster to install than to build.
"How will you handle [your specific requirement]?"
Replace with whatever matters to you — Arabic RTL, Mada and Tamara, ZATCA e-invoicing, a subscription model, migrating 5,000 products with their SEO intact.
You are not assessing the technical answer. You are checking whether they have obviously done it before. An agency that has will give you specifics and mention a complication you had not thought of. One that has not will say "yes, no problem."
"What do you need from me, and when?"
Projects slip because of client-side delays more often than developer-side ones. An agency that has run real projects will tell you upfront: product photos by week one, copy by week two, payment gateway account before testing.
Vagueness here predicts a project that stalls and gets blamed on you.
Warning signs
- A quote with no discovery. Anyone quoting a firm price for a custom build without asking about your catalogue, integrations and markets is guessing — and will come back for more.
- No written scope. "We'll build your store" is not a scope. You want a document listing pages, features and what is explicitly excluded.
- Payment fully upfront. Milestones are normal. 100% before work starts is not.
- They cannot explain a technical decision in plain language. Good developers can. Jargon as a shield usually hides uncertainty.
- A portfolio of stores that no longer exist. Check a few URLs. Dead links mean the clients left.
- Pressure to decide now. Discounts that expire tomorrow belong in retail, not professional services.
On price
Rates vary enormously by region, and cheap is not automatically bad — a competent team in a lower-cost market genuinely costs less than an agency in London or New York for the same work.
What matters is what the price includes. Compare quotes on:
- Number of custom-designed page templates
- Whether product data migration is included, and for how many products
- Whether redirects are included if you are replatforming (this matters enormously for keeping your search rankings)
- Rounds of revisions
- Post-launch support period
- Training and documentation
Two quotes that differ by 3x are usually quoting different jobs. Get them to itemise before comparing.
A sensible process
- Write a one-page brief — what you sell, how many products, which markets, must-have integrations, rough budget.
- Approach three agencies. Fewer gives you no comparison; more wastes your time.
- Ask the questions above on a call, and notice who asks you questions back.
- Get written scopes and compare them line by line.
- Start small if you can. A paid discovery phase or a small first project tells you more about working together than any interview.
Frequently asked questions
Should I hire locally or remotely?
Remote is normal now, and restricting to your city narrows the pool sharply. What matters more is overlap in working hours and clear communication. Ask how they handle the timezone gap.
How long should a Shopify store take?
A straightforward store on a premium theme: two to four weeks. A custom build with integrations: two to four months. Anything promising a bespoke store in a few days is selling theme configuration.
What if it goes wrong?
This is why scope and ownership matter. If the store is in your account and the scope is written down, a failed engagement costs you time and money but not the business. If neither is true, it can cost you everything.
