PrestaShop maintenance: the store still works next year, and someone answers when it does not.

What maintenance covers

The point of maintenance is that nothing on this list becomes an emergency. Each item is routine when done on schedule and expensive when done after the fact.

• Security: core and module patches applied on release, third-party modules reviewed for known vulnerabilities, hardening of admin and file permissions
• Updates: minor version upgrades, PHP version moves, module updates tested on staging first
• Backups: database and files, versioned, with restores actually tested rather than assumed
• Monitoring: uptime, error logs, checkout success, crawl errors, so problems surface before a customer reports them
• Performance: cache configuration, database maintenance, image pipelines, server sizing
• A person: one contact who knows your store, not a support queue rotating through strangers

Why it matters more on PrestaShop than elsewhere

PrestaShop is self-hosted and module-heavy. That is its strength - you own everything - and its exposure: every module is code from a third party running inside your shop, and the marketplace has a history of security advisories. A store with thirty modules and nobody watching the advisories is one bad module away from an injected checkout.

It is also the platform where version drift hurts most. A store left on an old PHP because "it works" becomes an upgrade project instead of an update, and the gap widens every release. Regular small moves are cheaper than one large one, every time.

Support when something breaks

Maintenance clients get a direct line to me, and the answer is from the person who knows the codebase. Checkout down, payment module failing after a provider change, admin blank after an update, a module fighting another module - these are the calls I take for the estate I run, and the diagnosis is faster because I have seen most of them before.

How the arrangement is structured - what is standing, what is on call, how it is billed - depends on the store and your team. Tell me what you run and I will propose something that fits rather than a package.
