PrestaShop audit
A full diagnosis of your store, delivered within 5 days with a costed action plan.
Modules, code, security, performance and technical SEO, analysed by the developers of nearly 300 PrestaShop modules. You choose who carries out the fixes.
Officially certified by PrestaShop.
DataFireFly is a PrestaShop Certified Agency for 2026 and a level 3 PrestaShop Expert, and our team holds the PrestaShop Expert certification (Core Skills). All three are awarded by PrestaShop itself.
About usYou are taking over a PrestaShop store, sales are dropping for no clear reason, every update is a worry, or you are preparing a migration to PrestaShop 9. Before spending money on fixes, you need to know where the real problems are. The PrestaShop audit gives you that overview, carried out by the team that writes and maintains nearly 300 PrestaShop modules: we know what a well-built module looks like, and what breaks in production.
What we analyse
Modules, overrides and code
A full inventory of installed modules, active or not: version, maintenance by the vendor, overrides of core classes, hook conflicts, scripts loaded on every page. We read the code of the modules and of the custom theme, where most bugs and slowdowns hide.
Security
PrestaShop and PHP versions, known vulnerabilities in installed modules, exposed sensitive files, admin accounts, backups.
Performance
Core Web Vitals measured on the pages that sell (home, category, product page, cart), the slowest SQL queries, cache configuration, size of the statistics and connection tables. See our article why your PrestaShop database weighs 8 GB.
Technical SEO
Indexing, canonical tags, hreflang on multilingual stores, URLs generated by faceted filters, redirects, 404 errors, structured data. On these topics, see our articles on the PrestaShop canonical tag, filters and crawl budget and 404 error audits.
What you receive
- A structured report by area, with the severity of each finding and the supporting evidence: code excerpts, measurements, screenshots.
- A prioritised action plan, from urgent fixes to deeper improvements, costed in days and euros.
- A one-hour debrief to answer your questions and set priorities together.
You are free to carry out the fixes with your team, another provider or us. The report does not change based on your choice.
What affects the price
The audit starts at €1,800, with a fixed quote:
| Factor | Impact |
|---|---|
| Number of modules | Every third-party or custom module is inventoried and read. |
| Custom theme | A heavily customised theme takes longer to review. |
| Multistore and languages | Each store and each language adds SEO and functional checks. |
| Volume | A large catalogue or a heavy database requires more performance analysis. |
The tools we publish to fix issues
Several common problems found during audits led to modules in our catalogue:
- PrestaShop database cleanup: statistics tables, obsolete carts and connections.
- 301 redirect manager with 404 error tracking.
- Hreflang tags for multilingual stores.
- Core Web Vitals: lazy loading, critical CSS and image optimisation.
- SEO facets: filter URLs indexed or excluded according to your rules.
What merchants say
Merchants who put their store back in order with our modules:
- “after importing from woocommerce and after three years of work i had a lot of duplicate attributes, especially sizes, making the related filter almost useless. now instead everything is much more organized.”
Giuliano Stella (clickintimo.it), duplicate attribute merge module (review translated from Italian) - “The module works perfectly and the support is very fast. Highly recommended.”
Massimiliano Baldizzone, PrestaShop Hreflang module - “Matches the description and works really well.”
Serge, LD Medical (ld-medical.fr), PrestaShop Cookie Manager module (review translated from French)
To date, every review published on our product pages is rated 5 out of 5.

Frequently asked questions
How much does a PrestaShop audit cost?
From €1,800. The price depends on the number of installed modules, the size of the catalogue, multistore and the topics to cover. The quote is fixed.
How long does it take?
Five business days between access being granted and delivery of the report, followed by a one-hour debrief.
What do I need to provide?
Read access to the code (SFTP or SSH), the database and the back office. We sign a non-disclosure agreement if needed. No changes are made to the store during the audit.
Is the audit neutral?
Yes. The report is the same whether or not you hire us for the fixes. You can have them done by your team, by another provider or by us.
Do you analyse modules bought on Addons?
Yes. Every installed module is inventoried: version, maintenance by its vendor, known vulnerabilities, overrides, performance impact. We flag the ones that pose a risk.
What does the report contain?
The findings by area, their severity, the supporting evidence (code excerpts, measurements, screenshots), then a prioritised, costed action plan.
Do I need an audit before migrating to PrestaShop 9?
It is recommended: the inventory of modules and overrides is the first step of a migration. See our PrestaShop 8 to 9 migration page.
