What's actually slowing down my Shopify Plus store?
Most Shopify Plus stores accumulate third-party apps and scripts over years of normal operation. Each one adds requests, loads external JavaScript, and introduces render-blocking code. The result is a store that looks functional in the dashboard but loads slowly for real customers on real devices. A Diagnostic Audit maps every external dependency, identifies which ones are active versus dormant, and tells you exactly what to remove, with documented before-and-after measurements so you can see the difference.
Most stores I audit are running 15 to 20 apps. Half of them are doing overlapping things. Several were uninstalled months ago, but the code they left behind is still loading on every page, on every visit, slowing every customer's experience. Before I remove a single line, I map what's actually there.

What does a Shopify Plus Diagnostic Audit include?
Script Tag Inventory
Every script tag on your store, categorised by source, purpose, and execution order.
App Dependency Map
Active and inactive apps cross-referenced with script execution. I identify what's still firing.
Ghost Code Report
A list of every script, stylesheet, and pixel from apps you're no longer using.
Performance Trace
A measured load trace. I annotate exactly which scripts are blocking your page and slowing your customers. Delivered as a waterfall with each offender identified.
Removal Recommendations
A prioritised list of what to remove, with risk rating and estimated performance gain per item. Every app gets a clear verdict: remove and replace natively, swap for a lighter alternative, or keep as-is with justification.
Native Replacement Opportunities
Apps you're paying for that Shopify can replace natively, with implementation complexity ratings.
12 and 36-Month Savings Projection
Based on your specific app stack: what the removal and native migration would cost you now versus what you'd stop paying over 12 and 36 months. The number your boss needs to approve the next step.

Start with a Diagnostic Audit →After the audit, you receive the report and, if you want it, a clear Overhaul proposal: scope, timeline, and a 36-month ROI model built around your specific app stack numbers. There's no pressure to proceed. The audit delivers value on its own. Most stores I audit end up with a clear case for the next step. The numbers make the decision obvious.
Pricing varies by store complexity and script volume. Confirmed before work begins.
Does a Diagnostic Audit require access to my Shopify admin?
Yes. A collaborator account with read access is the standard setup. No changes are made to your store during the audit. The collaborator access is removed when the engagement closes. If your team has restrictions on collaborator access, contact me before booking and we'll work it out.
Not sure if your stack is worth auditing?
Most stores I look at are carrying scripts from 3–5 uninstalled apps. The audit tells you exactly what's there, and what it's costing you, before anything is touched.
