Sound familiar?

The symptoms clients bring me

Every change takes days or weeks

Simple updates drag on because the code is a maze of custom and modules layered over the years.

The front-end is slow

A heavy, slow store quietly cuts conversion - and you don’t know which of the dozens of (possibly unnecessary) modules is choking it.

Upgrades feel too risky

You’re on an old Magento version and nobody can estimate the effort or risk of moving to a new one and securing the store.

You don’t know what you’re paying for

You pay an agency, results are thin, and you have no independent way to verify the quality.

Scope

What a Magento audit covers

Performance & Core Web Vitals

LCP, INP and CLS, server response time, full-page cache, indexers, database queries, and front-end and back-end bottlenecks.

Code quality & architecture

Spaghetti code, anti-patterns, plugin/preference abuse, and how far the code has drifted from Magento best practices.

Security

Critical vulnerabilities, missing security patches, data exposure, and GDPR alignment.

Upgrade readiness

A module inventory, upgrade blockers, and a realistic estimate of effort and risk.

Third-party modules

What’s actually used, what duplicates native Magento, and what can be safely removed.

Team / agency assessment

An independent, impartial view of the quality your current vendor is delivering.

Deliverables

A concrete report - not platitudes

  • A detailed report grading every finding by severity (critical / important / nice-to-have)
  • A prioritised roadmap - what to fix first for the biggest measurable impact at the lowest cost
  • Effort estimates in work-hours for every recommendation, so you can plan budget
  • A 60–120 min review session - we walk through the audit results together and I answer your team’s questions

On request, I’ll share an anonymised sample audit to review before we start working together.

Process

How a Magento audit works - step by step

Access & discovery

You hand over the source code as an archive or read access to the repository, plus an anonymised production database (no real sensitive data) and credentials to test accounts for every integration. We discuss the goals of the audit and what hurts most.

Analysis

I review code, performance, security and modules with hard data - profiling, metrics and static code analysis. I walk through the storefront and admin paths to understand the store’s business processes.

Report

You get a documented report: every issue found, its severity, its priority and an initial costed fix plan.

Review & roadmap

We walk through the report live, agree the order of work, and I answer your team’s questions.

Pricing

Transparent pricing, no surprises

You know upfront what you pay and what you get. The “from” prices are the starting point for a mid-size store - for large and very large stores (more integrations and modules) the quote rises a little. It is also higher for a headless storefront on a custom stack. For comparison, the same audit at an agency is typically several times the price.

Code & Architecture Audit

at an agency usually: from 3,800 USD
from1,650 USD
report in ~5 business days
  • Code quality & architecture (anti-patterns, plugin/preference abuse, technical debt)
  • Module inventory (what is redundant, what duplicates native Magento)
  • Security & GDPR (CVEs, 2FA, API keys, data exposure)
  • Report + prioritised roadmap
  • 60-min review session
Choose Code & Architecture

Performance Audit

at an agency usually: from 5,000 USD
from2,200 USD
report in ~7 business days
  • Everything in the Code & Architecture audit, plus:
  • Full performance & Core Web Vitals audit (LCP, INP, CLS)
  • Cache (FPC/Varnish), indexer and DB query analysis
  • Front-end and back-end bottlenecks (e.g. N+1 patterns)
  • 90-min review session
Choose Performance

Comprehensive Audit

at an agency usually: from 8,800 USD
from2,700 USD
report in ~10 business days
  • Everything in the Performance audit, plus:
  • Upgrade readiness (blockers, EOL version, effort & risk estimate)
  • DevOps & CI/CD audit (current infrastructure and processes)
  • Team / agency assessment
  • 120-min review session + 2 weeks of support
Choose Comprehensive

Indicative prices - the final quote depends on store size and the number of integrations.

FAQ

Magento audit - frequently asked questions

A Magento audit starts from a fixed, upfront price for the entry package (Code & Architecture), and you’ll find the full ranges of all three packages in the pricing on this page. The price depends on scope, store size and the number of integrations - but you always know it before we start, with no "pay for the unknown" billing. For comparison, the same audit at an agency is often several times more expensive.
The price is driven by: scope (a performance-only audit vs a full technical audit), codebase size, the number of custom modules and integrations, the edition (Open Source vs Adobe Commerce) and the frontend type (Luma, Hyvä, headless). A larger, more over-engineered store needs more analysis. That’s why there are three packages - you match the depth to your situation.
A full technical audit covers eight areas: performance and Core Web Vitals, code quality and architecture, security (patches, known vulnerabilities), upgrade readiness, performance problems (N+1 queries, indexers, caching (Redis/Varnish/FPC)), and module bloat and conflicts. Every finding gets a severity rating and a place in a prioritized roadmap. You get an independent picture of the whole, not a spot opinion.
Depending on the chosen package, I usually deliver results in 5–14 business days. The time depends on store size, the technologies used and the number of integrations. We agree the deadline upfront when defining the scope.
You get a written report with a severity rating for every finding, a prioritized remediation roadmap, an effort estimate in man-hours, and a live review session. It’s not a sales pitch - it’s a document you can act on yourself, with your own team, or with me. The goal is for you to make decisions on facts, not opinions.
No. A source-code archive (or read access to the repository) plus an anonymized copy of the production database is enough - I provide the tool and instructions to make that copy safely. The audit is non-invasive: I don’t touch the production environment, so the store runs without disruption.
No - the audit has zero impact on production, because nothing runs against the live environment. All analysis happens on a copy of the code and an anonymized database. Customers keep shopping while you get a full diagnosis with no risk of downtime.
The most common causes are N+1 queries, a disabled or misconfigured full page cache, indexers set to "update on save", module bloat and conflicts, and underpowered hosting. It’s usually not one thing but several overlapping ones - which is why audit data beats guessing. The audit pinpoints exactly which of these apply to your store.
LCP responds most to critical CSS, prioritizing the main image and deferring unnecessary JavaScript; INP improves with throttling and splitting scripts, and CLS with reserving space for images and banners. The result depends heavily on the frontend: Hyvä starts from a much better position than Luma. The audit measures your real values and points to the most cost-effective fixes.
TTFB (Time To First Byte) is how long the server takes to start responding - in Magento it’s usually a backend bottleneck. It’s lowered by a properly working full page cache (Varnish), Redis for sessions and cache, eliminating N+1 queries, and the right hosting. It’s one of the first areas I check in a performance audit.
An N+1 query is a pattern where the code runs a separate database query for every item in a list instead of one batched query - with a large catalog it can kill listing and product-page performance. In Magento it often comes from poorly written custom code or low-quality third-party modules. In the audit I profile queries and point to the exact places in the code that generate them.
The upgrade itself is "free" under the licence - you pay for engineering time, and its main driver is the number of custom modules and extensions - the less "mess", the easier the upgrade. An upgrade-readiness audit checks what will break before you commission the work, so the quote stops being a lottery. That tells you whether it’s cheaper to upgrade now or clean up the code first - which makes every future upgrade less time-consuming, and therefore significantly cheaper.
A security audit checks for missing patches, outdated modules, admin hardening and known vulnerabilities (CVEs) for your version. Important: applying a patch closes the hole but doesn’t undo the damage if the store was already hacked. That’s why the audit also looks for signs of a prior compromise, not just missing patches.
Yes - I audit Magento Open Source, Adobe Commerce (Enterprise) and B2B, and the open-source Mage-OS fork. On the frontend I cover classic Luma, Hyvä (Theme and Checkout) and headless setups. Regardless of edition and frontend, the audit methodology is the same - though a headless setup can be considerably more time-consuming, which affects the quote.
The audit is a diagnosis and a plan - I can do the fixes separately or prepare concrete tasks for your team and discuss estimates. You decide whether we work together or you handle it in-house from the roadmap. Either way, you leave the audit with a clear list of "what, in what order, and how much work it takes".
