How much should ongoing support cost after launch?

The costs that never stop

Anything you put live has a few running costs baked in, whoever built it: somewhere for it to live online, the web address, and any tools it leans on. For a simple site or automation this can be a few pounds a month, or close to nothing. For something bigger it is more. This is not support. It is just rent, and it is unavoidable.

Support is the separate question of who fixes things, makes changes, and keeps it healthy. That is where the money, and the confusion, tends to live.

What good support actually covers

A fair support arrangement is paying for a real thing, not a vague sense of safety. Properly, it covers:

• Keeping the thing secure and up to date, so it does not quietly rot or turn into a risk.
• Fixing things when they break, without a fresh negotiation every single time.
• Small changes as your needs shift: a new page, a changed form, a tweak to how something works.
• Someone who already knows your setup being on hand, so you are not explaining it from scratch in the middle of a crisis.

If you cannot see what a monthly fee is buying you, that is exactly the question to ask before you sign it.

What it should cost

For a simple site or tool, you often do not need a formal retainer at all. Pay the small running costs, and handle the occasional change as a one-off when it comes up. Paying a monthly fee to maintain something that barely changes is money for nothing.

For something you rely on daily, a modest monthly retainer is fair, and it should reflect the size of what it covers. A small setup might be a low monthly figure. A larger, business-critical system that has to stay up is more, because keeping it that way is real, ongoing work. The test is simple: the retainer should map to actual work and real cover, not just a standing charge for existing.

The trap to avoid

The one to watch is a support deal you cannot leave: where the person who built it is the only one who can touch it, holds all the keys, and can charge what they like because you have nowhere else to go. That is not support. That is a hostage situation with an invoice attached.

The protection is ownership. If what you paid for is properly handed over and documented, any competent person can pick it up, which means you stay on a retainer because it is good value, not because you are trapped. Everything I build is handed over that way, on purpose.

So what should it cost?

For a lot of small setups: almost nothing beyond the basic running costs, with changes handled as they arise. For something you truly depend on: a fair monthly retainer that matches the work involved, and that you are always free to walk away from. The way to land on your number is to be honest about how much the thing will really need once it is live.
