What the audit tells you

Focus your development time where the update actually needs attention.

The audit filters out noise and evaluates the customizations that matter—not thousands of unstructured diff lines.

01

Customization inventory

Identify custom snippets, sections, assets, metafields, Liquid changes, CSS, JavaScript and other shop-specific theme modifications.

02

Update status

See whether each detected customization is fully present, probably present, only partially integrated or missing from the new theme.

03

Risk and next steps

Understand where a straightforward reintegration is likely and where the new theme structure requires adaptation, testing or a technical review.

Illustrative report preview

A decision-ready report—not a code dump.

Every detected customization is grouped by purpose and assessed separately for migration status, structural changes, technical conflicts, business urgency and reintegration risk.

Example content shown for illustration. Your audit is generated from your own two theme ZIPs.

How it works

Two theme exports in. One clear report out.

1

Purchase one audit

Pay €49 excl. VAT once. There is no subscription.

2

Upload both themes

Upload the customized theme from before the update and the new theme version as Shopify theme ZIPs.

3

Receive the report

The comparison is automated, then manually quality-checked. Your structured English report is delivered by email within 24 hours.

Confidentiality

Your theme code stays private.

Your uploaded ZIPs are stored in a protected, non-public server directory and used only to perform your audit. They are never published or made available as downloads.

Technical data extracted from the theme files is processed for the automated comparison and report generation. Access is limited to the service operation and the manual quality review.

The files are retained only for the time needed to complete, review and deliver the audit, then handled according to the privacy notice linked below.

Important to know

Custom code is not always clearly labelled.

Custom snippets, sections, assets, metafields, CSS, JavaScript and clearly commented changes can usually be identified reliably.

For unlabelled edits inside standard theme files, a two-version comparison cannot always prove whether a difference came from your developer or the theme vendor. The report flags these uncertainties instead of presenting guesses as facts.

The audit is a diagnosis. Custom-code migration, implementation and repair are not included in the €49 price and can be quoted separately if needed.

FAQ

Frequently asked questions

Who is the audit for?

It is designed for Shopify agencies, freelancers, developers and merchants who need to understand what happened to custom theme code during an update. This is a B2B service for business customers only.

What is not included?

The audit identifies affected customizations and recommends what should be reviewed or reintegrated. Programming, repair and migration work are not included in the €49 audit.

What if the custom code was not commented?

Uncommented custom code may still be detectable through custom snippets, sections, assets, metafields, functions, CSS or unusual changes. Isolated edits inside standard theme files cannot always be attributed with certainty; the report marks those limitations clearly.

Can I use the audit after the update has already happened?

Yes. You only need an export of the customized theme from before the update and an export of the new theme version after the update.

What if a reliable audit is not possible?

If the uploaded files do not provide enough evidence for a meaningful Theme Update Audit, the purchase price will be refunded in full.

When will I receive the result?

The audit is generated automatically and manually quality-checked before delivery. You will receive the English report by email within 24 hours after both theme files have been uploaded successfully.
