Hiring a Shopify agency feels a lot like online dating. Everyone has a slick profile, a confident pitch, and a portfolio that looks amazing until you actually click something. Then you find out the "award winning store" was a free theme with the logo swapped.
The good news: a handful of pointed questions will expose the pros from the posers in about fifteen minutes. These are the exact questions to ask a Shopify developer before hiring, plus what a good answer actually sounds like. Bring them to your next call and watch the vague ones squirm.
🎯 Quick Summary
- Confirm they are a verified Shopify Partner before anything else. It is a five second check that filters out hobbyists.
- Demand live store links, not screenshots. Real proof clicks, loads, and checks out.
- Get ownership in writing: you should own the code, the theme, and every account at the end.
- Ask who you actually talk to and how often. Silence is the number one agency horror story.
- Sort out post-launch support before launch, not after something breaks on a Friday night.
✅ Are they a real Shopify Partner?
This is question one because it takes five seconds and rules out a surprising number of people. A Shopify Partner is a developer or agency officially registered in Shopify's program. They get early access to platform changes and build inside Shopify's actual rules instead of guessing.
So ask it plainly: "Are you a verified Shopify Partner, and how long have you focused on Shopify specifically?" You want someone who lives on Shopify, not a generic web shop that also does WordPress, business cards, and occasionally fixes printers.
- Green flag: "Yes, here is our partner profile, and we work on Shopify full time."
- Red flag: "We can build on any platform!" Jack of all trades, master of your refund request.
📂 Can they prove the work?
Anyone can paste a gorgeous mockup into a deck. Mockups do not have to load, convert, or survive a real checkout. So make them show their work, live.
Ask: "Can you send me three live stores you built, ideally in my industry?" Then go click around. Add a product to the cart. Resize the window on your phone. A store that looks perfect on desktop and falls apart on mobile tells you everything about how they test.
While you are clicking, pay attention to the unglamorous stuff that quietly drives sales, like how collections are ordered and how products are merchandised. If you want to understand why that matters so much, our guide on collection order and conversions is a good primer. A great agency obsesses over this. A weak one just centers the logo and calls it a day.

🔑 Who owns the code?
This is the question that saves founders from the worst kind of breakup: the one where your ex keeps the house. Some agencies build on their own proprietary framework or hold your accounts hostage, so leaving them means rebuilding from scratch.
Ask these three, slowly, and listen: "When we are done, do I own all the code and the theme? Are all accounts (Shopify, domain, apps) in my name? If we ever part ways, can another developer pick up where you left off?"
| What to ask about | Answer you want | Answer that should scare you |
|---|---|---|
| Code and theme | "You own it outright." | "It runs on our private platform." |
| Accounts and domain | "All in your name." | "We manage that for you." (translation: we hold the keys) |
| Handover | "Any Shopify dev can continue." | "Only we can maintain it." |
| Documentation | "We leave clean, documented work." | "You won't need it." (you will) |
Clean ownership is not a nice to have. It is the difference between hiring a partner and signing a lease you cannot break.

💬 How do they work and communicate?
The single most common agency complaint is not bad code. It is silence. You pay a deposit, things feel great for a week, and then your messages start echoing into the void. So pin down the process before money changes hands.
Ask the boring logistics questions, because boring is what protects you:
- "Who is my point of contact?" You want a named human, not a shared inbox that nobody owns.
- "How often will I get updates, and on what channel?" Weekly check-ins and a shared project board beat "we'll let you know."
- "What is the realistic timeline, with milestones?" A real timeline has dates and phases. "A few weeks-ish" is a coin flip.
- "How deep is your Liquid expertise?" Liquid is Shopify's templating language, the thing that powers custom layouts and dynamic content. Deep Liquid skill is the line between a true custom build and a bloated pile of apps that slow your store to a crawl.
- "How many rounds of revisions are included?" Know this before you fall in love with a design.
If the answers are specific and calm, that is a team that has done this before. If they get fuzzy on timelines and contacts, that fuzziness will define your whole project.
🚀 What happens after launch?
Launch day is not the finish line. It is the day real shoppers start finding the bugs your test orders never did. The right question is: "What does support look like after we go live?"
You want to know if there is a support window for fixes, whether they offer a maintenance retainer, and how fast they respond when something breaks. Stores need ongoing care: apps update, themes need patching, and SEO details quietly make or break your traffic. For example, handling discontinued products correctly with proper redirects is exactly the kind of post-launch job that protects your rankings, which we cover in our piece on out of stock products and 301 redirects.
If growth is the goal, also ask whether they handle ongoing work like SEO and paid search, or whether you will be juggling three vendors who all blame each other when something goes wrong. One accountable team is worth a lot.
Here is the honest part. If you are technical, patient, and have time to spare, you can vet and manage all of this yourself. But if downtime costs you money and your time is better spent running your business, this is exactly where you hire a pro. A real Shopify partner agency answers every one of these questions without flinching, because they have nothing to hide and everything to back up.
That is the whole job of these questions to ask a Shopify developer before hiring: turn a charming pitch into a clear yes or no. Ask them, trust the specific answers, and walk from the vague ones. When you are ready to ask them to a team that actually enjoys this stuff, book a discovery call with CartWorks and put us on the spot.
