The hidden cost of website maintenance (and how to calculate it before signing)

Almost every website quote talks about the launch cost. Almost none talks about what it costs to keep it alive for the following three years. And that second number, added up, is usually bigger than the first.

What goes into the “hidden cost”

Hosting and domain. It looks minor, but it varies a lot: from a few euros a month to hundreds, depending on traffic and whether hosting includes backups and real support.

Plugin or app licenses. Every premium WordPress plugin, every Shopify app, usually carries an annual fee. A store running ten active apps can rack up several hundred euros a year in licenses alone, with nobody having budgeted it as a separate line.

Security updates. Ignoring them is free until it is not: a compromised site costs far more in reputation and recovery hours than years of preventive maintenance.

Support hours for small changes. Changing a line of text, uploading an image, fixing a button that broke after an update. If every small change requires an invoice from an outside provider, those hours add up fast.

How to calculate the real three-year cost

Watch out: always compare the three-year total cost, not just the launch price — it is the only honest way to compare quotes.

A simple way to estimate it: launch price + (monthly hosting and license cost × 36) + (estimated support hours per year × rate × 3). With that number in hand, two quotes that looked very different upfront can end up practically equal — or the reverse: the “cheap” one turns out to be the most expensive.

Why owned code usually costs less in the medium term

Not because the initial build is cheaper (it usually is not), but because it removes most of the lines above: no third-party plugin licenses to renew every year, simpler security updates because there is less surface exposed, and content changes the team can make on its own instead of depending on a provider for every piece of text.

Questions to ask before signing

• What exactly does the maintenance fee include, and what gets billed separately?
• How many hours of small changes are included per month?
• What happens if I stop paying for maintenance: does the site keep running, or does it get locked?
• Is there an exit cost if I decide to switch providers?

How we do it at Bitora

We always give the three-year total cost in the proposal, not just the launch price, so the comparison against other quotes is fair. And because the code is yours from day one, there is no hidden exit cost if you ever decide to switch teams.
