Expiring app APIs
Shopify regularly retires old API versions, quietly breaking any custom integrations left unmaintained.
Your store, kept fast, current and improving by a Shopify Plus Partner with 55+ certifications. 24/7 coverage, every task estimated and the cost guaranteed.







Shopify keeps the platform running, but not your theme, apps or customizations. Those slip quietly, and these are the failure patterns we see most.
Themes
Add themeTheme library
Shopify regularly retires old API versions, quietly breaking any custom integrations left unmaintained.
Checkout Extensibility replaces legacy code, forcing migrations by deadline instead of plan.
Years of "just install it" stack app scripts, making pages crawl and conversions drop.
Edits made directly in the theme block clean updates, so the store falls behind on features, speed and fixes.
A single freelancer knows every customization, until they're on holiday, or gone.
Webhooks stop, syncs drift, and the first sign is wrong stock or a missing order, found by a customer.
One team, every discipline your live store needs. All of it runs through one process and one client Portal, no juggling vendors.
Storefront, checkout, apps and integrations watched around the clock, so problems are caught before they cost revenue.
Theme updates without losing customizations, and a storefront that stays cleanly updatable.
Custom apps kept current as Shopify retires API versions, and the app pile kept under control.
Checkout customizations migrated and maintained on checkout extensibility and Shopify Functions.
App-script audits, theme optimization and speed programs that keep pages fast as the store grows.
Broken checkout, failing app or display bug, every issue triaged by severity.
ERP, PIM, payment and shipping integrations built, fixed and kept in sync.
Every store we run goes through SOLVE, Structured Operations for Live Ecommerce. Our team works with AI at each step, and whatever lands in the queue gets solved.
Anything store-related lands in the Magebit Portal, our client layer on top of Jira.

No request is picked up blind. It gets understood, sized and priced before anything moves.

Your go-ahead starts the clock. The fix is built, checked and released through one flow.

You hand over a request and get back a working solution. The middle is ours to run, and you can watch every step of it.
A typical agency closes your ticket and forgets it. Ours keeps the memory of every Shopify and commerce store we run working for yours.

New tickets are compared with solved ones across our client base, so work starts from experience.

A returning problem is recognised and lands with the developer who fixed it before.

An API retirement hitting several stores the same week gets one investigation, covering all.

Cross-store patterns become advice for yours, the migration due, the slow app, before you raise it.
Our engineers ship their own AI tools, an open-source MCP layer among them. Every support task gets that same leverage.
Connect Magebit to Claude, ChatGPT, Cursor or any MCP-compatible AI tool.
Set up your AI tool
Run this in your terminal:
claude mcp add magebit-client-portal --transport http \
https://client.magebit.com/mcp \
--header "Authorization: Bearer <your-api-key>"Every price is sanity-checked by AI, so it tracks actual effort rather than padding
Clearly-scoped tasks can be done by AI from start to finish, with a certified developer signing off before release
More gets done per hour and turnarounds shrink, with the quality bar exactly where it was
That speed lands in your estimates, not only in our margin
No AI-built change reaches a live store without a human developer’s review. Ever
Every change passes four gates before it goes anywhere near production. None of them can be skipped, the system won’t allow it.

Every task is tested against a checklist from the approved scope, on the devices the change actually affects.
What was tested, on which devices, with screenshots and a recording. Never a bare “done”.
Dependency and vulnerability scanning on every repository, under yearly-audited ISO 27001 practice.
If a bug escapes, we trace which gate should have caught it, and it becomes a new automated check.

Your support runs like a product through SOLVE and the Magebit Client Portal, never as a pile of tickets.
AI accelerates every task, and a certified developer puts their name on everything that ships.
We arrive with proposals and fixes rather than open questions, often before you’ve asked.

Nothing starts without an estimate, and your approval locks the price under the Fixed Cost Estimate Guarantee, any overrun is absorbed by us. There’s no retainer sitting unused and no invoice you didn’t see coming.
