Shopify Maintenance Checklist for D2C Brands

Most Shopify stores don't break because of one big mistake. They break because of small things nobody was watching: an app update that changed the checkout, a theme edit that never got tested on an iPhone, a script added for a campaign and never removed. By the time you notice, you're usually in the middle of a sale.

This is the checklist we'd want a D2C brand to run through — monthly, and again before any sale or festive season. If you'd rather not run it yourself, there's a note at the end on when handing it to someone makes sense.

Every month

**Test the full buying journey on a phone.** Open the store on a real mobile device, add a product, go through checkout and complete a test order with each payment method you offer. This one habit catches more problems than any tool.
**Review installed apps.** Remove anything you don't actively use. Every app can add scripts to your storefront, and leftovers from old campaigns are a common cause of slow pages and odd behaviour.
**Check for updates.** Apps and your theme release updates; stores that never update drift out of sync with Shopify itself. Update one thing at a time and re-test after each, rather than updating everything at once.
**Look at your speed.** Run the free store speed audit and note your mobile score and Largest Contentful Paint. A single month-on-month comparison tells you whether something new made things worse.
**Check your backups.** Confirm you can restore your theme and export your products, customers and orders. A backup you've never tested is a hope, not a plan.
**Scan for broken links and missing images.** Product pages, collection pages and footer links break quietly after catalogue changes.
**Confirm your tracking still works.** Check that purchase events still reach your analytics and ad platforms after any theme or app change.

Before every sale or festive season

**Freeze changes a few days ahead.** Decide a cut-off after which nothing changes on the store except content. Last-minute edits are where sale-day disasters come from.
**Load-test the likely path.** Run through homepage → collection → product → cart → checkout on mobile, on a normal connection, not just on office Wi-Fi.
**Check your discount logic.** Test every discount code and automatic discount, including combinations, free-shipping thresholds and minimum order values.
**Check inventory and variants.** Make sure stock levels are correct and that sold-out variants behave properly, so you don't oversell.
**Confirm payment and shipping integrations.** Place real test orders with each payment gateway and check the shipping rates that appear.
**Decide who is on call.** Know exactly who to message if checkout breaks at 11 PM, and that they can actually fix it.
**Watch the store during the sale.** Keep an eye on orders, checkout completion and page speed in the first hours, when a problem is cheapest to fix.

Quarterly

Review the theme code for leftover experiments, duplicated sections and unused snippets.
Audit your pages for accessibility basics: image alt text, readable contrast, and tappable buttons on mobile.
Re-check redirects after any URL or collection changes, so you don't leak search traffic.
Review what you pay for apps against what you actually use.

Signs it's time to hand this over

Doing this yourself works while the store is small. It stops working when:

a sale or launch is coming and you can't afford to find out about problems from customers;
the person who built the store is no longer available and nobody else understands the theme;
you're repeatedly putting off updates because you're afraid of breaking something;
your speed has crept down and you don't know why.

That's what a maintenance retainer is for. Our Website Care Plans cover monitoring, backups, updates and small changes for Shopify and WordPress sites, described by developer hours and response time so you can see what you're getting. If you'd like us to look at your store first, send us a short brief or run the free speed audit.
