Shopify Maintenance Packages on a Monthly Retainer.

How much do Shopify maintenance packages cost per month?

Shopify maintenance packages start at $299/month and run to $1,799/month, and every one of them is a monthly retainer. We price by tier, not by revenue, so what you pay tracks how much development a month your store actually consumes and how fast you need us to respond, nothing else. Every plan is a flat monthly fee: no hourly billing, no surprise invoices, and 10% off when you pay annually. If you need more development capacity than a maintenance tier covers, you can hire a Shopify developer on a dedicated or part-time basis instead.

Starter Care is the low-risk way in: a free store audit to begin, no lock-in, and an always-on safety net of uptime and broken-link monitoring, monthly backups, a monthly vitals snapshot, and small fixes. Upgrade to Growth within 60 days and we credit the Starter fee in full.

Essential is the base plan for a stable store: 20 hours a month, same-business-day response, updates managed, bugs fixed, vitals watched.

Growth is the flagship and the best value for most brands: 40 hours a month on a 4-hour SLA, plus a priority Slack pod, a quarterly CRO review with 1-2 tests shipped, ongoing SEO monitoring, and a dedicated account contact. This is the tier where the store doesn’t just stay healthy, it improves.

Scale is for Shopify Plus and multi-store setups where maintenance blends into ongoing development: a custom 70+ hour band, the tightest SLA we offer, and a monthly strategy call.

What is a Shopify monthly retainer, and why not pay hourly?

A Shopify retainer is a standing monthly agreement: a flat fee buys a band of development hours plus always-on maintenance, rather than billing by the hour or scoping every small change as a separate project. The point is not the hours on paper, it’s that the store has a team that already knows it and watches it daily.

Hourly billing sounds cheaper until you live with it, then it doesn’t. Every request becomes a quote, every quote becomes a delay, and the small fixes that quietly cost you conversions never make the cut because they’re not worth the admin. A monthly retainer removes that friction: the fix that would take a fortnight to scope and schedule elsewhere ships this week, because the relationship and the hours already exist.

The flat fee is the part that matters most. You know the number before the month starts and it doesn’t move, which is the opposite of the hours-only agencies where the invoice is a surprise you open at month-end.

What a Shopify maintenance retainer covers

A Shopify store is software, and software drifts. Themes ship updates that quietly break customised sections. Apps change their APIs, their pricing, or disappear entirely. Checkout requirements evolve, Core Web Vitals thresholds tighten, and the “small fix” list grows faster than anyone inside the business has time to handle. A maintenance retainer is the fix for drift. Here’s what ours covers on every tier:

Theme and app updates, managed. We review update changelogs before applying anything, test on a duplicate theme, and roll out without downtime. When an update would break a customisation, we adapt the customisation instead of skipping the update, skipped updates are how stores end up unfixable two years later.

Security and uptime. Shopify handles platform security, but your theme code, third-party scripts, and app permissions are on you. We audit script tags quarterly, prune abandoned app permissions, and monitor uptime so a broken deploy never runs silent for a weekend.

Core Web Vitals. Every month you get a report on LCP, CLS, and INP against the previous month, with the cause named when something regresses. Speed decays through app additions and content changes, catching a 300ms regression in month one is cheap, catching it in month twelve is a project.

Bug fixes and small enhancements. The rolling list every store accumulates: a spacing bug on mobile, a new badge on PDPs, a banner for the next drop. Retainer hours cover them inside the month instead of waiting for a project slot.

Quarterly CRO review (Growth and above). Maintenance keeps the store healthy; the quarterly review makes it better. Every three months we review funnel data and ship 1-2 conversion tests, so the store improves on retainer rather than just surviving.

Shopify maintenance vs hiring in-house

The alternative to a maintenance retainer is usually a part-time Shopify developer or a junior hire. The maths rarely favours it below a certain size. A capable Shopify developer costs far more per month than any of these tiers, comes with the overhead of recruitment and management, takes holidays, and, crucially, brings the experience of one store: yours.

A retainer brings the pattern recognition of a team that maintains dozens of Shopify stores. The bug you hit is one we’ve seen before. The app conflict was diagnosed on someone else’s store last quarter. The Core Web Vitals regression has a known cause. You’re buying breadth of exposure, not just hours, and you can scale the hours up or down a tier as the store’s needs change without hiring or firing anyone.

In-house wins once the store is large enough to keep a full-time developer genuinely busy every day. Below that, a retainer is cheaper, faster, and better-informed.

How to choose a Shopify maintenance agency

Plenty of Shopify agencies say they offer maintenance and support plans. Four questions separate a real maintenance partner from a ticket queue:

1. Is the fee flat and known in advance? If the answer involves “it depends on hours,” you’ll be opening surprise invoices. Ours is a fixed monthly number by tier.
2. What’s the response SLA, in writing? “We’ll get to it” is not an SLA. Ask for the guaranteed response time, and check whether emergencies jump the queue. Ours range from same business day to 4 hours.
3. Does maintenance include improvement, or only survival? A plan that just applies updates keeps the store alive. A plan with a CRO review built in makes it better. Growth and Scale include one.
4. Can you leave? Long lock-ins protect the agency, not you. We ask for 90 days to make setup worthwhile, then you can cancel any time, and Starter Care has no lock-in at all.

If you want to see which tier fits before committing to anything, send your store through the form. The store review is free and comes back within 48 hours with what we’d watch, what we’d fix first, and the plan we’d recommend.
