Hiring a Shopify developer for a new store, redesign, speed fixes, or a migration is a high-impact decision. The wrong hire can break checkout, slow down your storefront, and hurt SEO. Use this checklist to vet candidates with confidence.
1) What Shopify projects have you shipped that are similar to mine?
Why it matters: “Shopify experience” is broad. You want proof they’ve handled your type of store (catalog size, apps, integrations, multi-market, B2B rules).
What to listen for
- Specific examples with similar complexity, not just “we build Shopify stores”.
- Clear explanation of what they built and what trade-offs they made.
Red flags
- No portfolio links or only generic claims.
- They can’t explain the why behind decisions.
2) Will you work on theme customization, custom app development, or both?
Why it matters: Some problems are theme/UX issues. Others need backend logic using apps or Shopify Functions. The best approach is usually “keep the theme lean, put logic in the right place”.
What to listen for
- Comfort with Online Store 2.0 theme structure and maintainable customization.
- Ability to explain when to use an app or Functions (and the impact on upgrades).
3) How do you handle Shopify APIs and integrations?
Why it matters: Most serious stores rely on integrations (ERP, CRM, shipping, analytics, subscriptions). A strong developer understands secure API access, webhooks, and platform limits.
Ask which APIs they’ve used and how they keep integrations safe and stable. For reference, Shopify’s developer documentation is here: Shopify.dev.
Red flags
- “We’ll figure it out later” without a plan for auth, permissions, or webhooks.
- They don’t ask what systems you need to integrate.
4) What is your approach to performance and Core Web Vitals?
Why it matters: Store speed affects conversions and SEO. Your developer should talk in actions, not promises.
What to listen for
- App bloat audit, script control, image strategy, and real-device testing.
- Clear plan to improve LCP/INP/CLS and keep them stable over time.
If they’re serious about performance, they’ll align with the metrics and guidance defined by Google: Core Web Vitals (web.dev).
5) How do you protect SEO during a redesign or migration?
Why it matters: Shopify rebuilds often lose rankings due to broken URLs, missing redirects, duplicate content, or indexing mistakes.
What to listen for
- URL mapping + 301 redirect plan, canonical handling, and post-launch monitoring.
- Search Console checks and crawl validation after deployment.
A competent answer should match best-practice guidance from Google: Site move with URL changes (Google Search Central) .
6) How do you test changes before going live?
Why it matters: Shopify changes can break cart, checkout, shipping rules, discounts, tracking, or apps. Testing is non-negotiable.
What to listen for
- Theme preview / staging workflow.
- A documented QA checklist (cart → checkout → payments → tracking).
- A rollback plan if something goes wrong.
7) What’s your workflow for version control and collaboration?
Why it matters: Without a proper workflow, changes get overwritten and bugs become expensive. You want a Shopify CLI + Git process with clear releases.
Red flags
- “We don’t use Git” or “We only edit in the Shopify admin”.
- No review process or change history.
8) Who owns the code, and what documentation will I receive?
Why it matters: You want ownership and a clean handover so you’re not locked in.
What to listen for
- You own the code, access to repos, and documentation for key areas (theme customizations, integrations, tracking).
- Credential handover and a simple maintenance guide.
9) What support and maintenance do you offer after launch?
Why it matters: Stores need ongoing fixes and improvements: app updates, tracking changes, conversion tweaks, seasonal changes, and new features.
What to listen for
- Support response times (SLA), what qualifies as a bug, and how requests are handled.
- Retainer options for continuous optimization.
10) Can you share a clear timeline, milestones, and deliverables?
Why it matters: “2–3 weeks” means nothing without scope. A professional breaks work into milestones with measurable outputs.
What to listen for
- Discovery → build → integrations → QA → SEO checks → launch + monitoring.
- Risks and assumptions called out early.
