Shopify hosts your store, keeps the platform secure and runs the checkout. So why would a Shopify store need a developer on call? Because the platform is only part of the picture. Your theme, apps, integrations and customizations are what make the store yours, and they need looking after.
This guide explains what can go wrong on a live store, what a good maintenance plan covers, and how to choose between a monthly retainer and fixing things as they come up.
Key takeaways
- Shopify looks after the platform. You or your developer look after the theme, apps, customizations and integrations.
- Most expensive problems are cheap to prevent. A store that breaks during a sale costs far more than a regular check.
- A retainer buys speed and familiarity. Pay-as-you-go suits simple, stable stores.
What can go wrong on a hosted platform
- App conflicts. A new app, or an update to one, can clash with your theme or with another app.
- Creeping slowness. Every app and third-party script adds weight, and pages get slower little by little. Apps you uninstalled can also leave code behind.
- Platform changes. Shopify releases new API versions on a regular schedule and retires old ones, so custom apps and integrations need periodic updates. Theme and checkout capabilities also evolve, and customizations built the old way can need rework.
- Content that breaks layouts. A very long product title or a missing image can break a design that looked fine in testing.
- Lingering access. Former staff, agencies and freelancers often keep access long after they've finished.
- Silent tracking failures. Analytics and advertising pixels can stop firing without anyone noticing.
What a maintenance plan should cover
Fixes and troubleshooting
Layout bugs, broken features, app conflicts, and cart or checkout problems. This is the part most people think of first.
Updates and compatibility
Theme and app updates tested on a duplicate theme before they go live. API version upgrades for custom apps and integrations. Replacing features Shopify has deprecated.
Performance
Image optimization, removing unused apps and leftover code, deferring heavy scripts, and checking page speed on mobile.
SEO health
Redirects, broken links, structured data, and titles and descriptions after content changes.
Security and access
Reviewing staff and collaborator accounts, making sure two-step authentication is on, and removing apps nobody uses.
Integrations
Checking that connections to email, subscriptions, search and reviews still work, and that webhooks aren't failing.
New features and improvements
Small enhancements such as a new section, a promotional banner or a test of a different layout. This is where a developer who already knows your store saves the most time.
Retainer or pay-as-you-go?
| Monthly retainer | Pay-as-you-go | |
|---|---|---|
| How it works | A set number of hours each month, usually with priority response | You ask when you need something, and it's quoted or billed by the hour |
| Strengths | Predictable budget, faster response, and a developer who knows your store | No commitment, and you pay only for what you use |
| Watch out for | Unused hours that don't roll over, so agree on that in advance | Slower to start, since the developer may need to get familiar with the store again |
| Best for | Stores with frequent promotions, custom features or integrations | Simple stores that rarely change |
If your store depends on custom code or runs regular campaigns, a retainer usually pays for itself the first time something breaks at a bad moment.
Prepare for busy seasons
Run a full check a few weeks before major sales periods such as Black Friday and Cyber Monday, holiday seasons or your own launches:
- Test the cart, discounts, shipping rules and checkout on a phone, start to finish.
- Review page speed on mobile.
- Stop non-essential changes close to the date.
- Know exactly who to contact if something breaks, and how.
If your promotions rely on custom discount logic, see how custom discounts work with Shopify Functions, including what to test.
A simple monthly checklist
- Place a test order, including a discount code, through to checkout.
- Check the store on a real phone and in more than one browser.
- Review page speed on your home, collection and product pages.
- Look for broken links and failed redirects.
- Review installed apps and remove any you no longer use.
- Review staff and collaborator accounts.
- Check that tracking, email and subscription integrations are still working.
- Back up the theme by duplicating it before any changes.
- Note any upcoming Shopify or app changes that affect your customizations.
What to ask a maintenance provider
- How quickly do you respond to urgent issues, and how do I reach you?
- What do the monthly hours cover, and what is billed separately?
- Do you test on a duplicate theme before changes go live?
- Do you keep version history of theme changes, so we can roll back?
- Will I get a short summary each month of what was done?
- What happens if you're unavailable?
