There’s a moment, usually about eighteen months after launch, when the original developer has gone quiet, a plugin update has gently broken the contact form, a backup nobody checks has stopped running, and the site is two security patches behind. Nothing looks wrong from the outside. The slow rot is the point.
Then something visible breaks — the site goes down on the morning of a press release, an enquiry form silently stops sending for six weeks, a flagged security warning appears next to your domain in Chrome — and suddenly a developer is being phoned in a panic, at panic-rate, to do the work that should have been a thirty-minute job a quarter ago. It costs more, it takes longer, and the person doing it doesn’t know your site.
A small monthly retainer is the unsexy alternative. The work is genuinely boring — check the updates, run the backup, confirm the forms still send, watch the speed numbers, do the little content tweak you’ve been meaning to ask about. It costs less than one panic phone call a year, and the panic phone call doesn’t happen.
