// managed-development.retainer

We replace the systems you've outgrown.

Spreadsheets, plugins and manual workarounds get a business started — they don't scale with it. Moonfive builds the software you actually need, then stays on as the team that keeps it running.

Managed Development Retainer

From £1,500/month, plus a £1,500 one-time setup fee. Scales with need — book a call to scope.

No lock-in contract. Cancel any time. One month's notice for handover.

Included at every tier

  • We monitor your site and systems every day, so problems get caught before they affect you
  • Every update is tested before it goes live
  • Automatic backups, stored safely away from the live site
  • Your own portal to report issues or request new features, any time

Support

From £250/month. For a system that already does what you need. We keep it safe and running: hosting, daily monitoring, off-server backups, bug fixes and security updates. No new features. If you need some, move up to the retainer for as long as you need them.

Systems we didn't build need a one-time £750 setup first: a code audit, a move onto our hosting and a restore test.

A head start, not a blank page

Before we design anything from scratch, we check whether one of these already does most of the job. Real systems, built and running today, not concepts on a slide.
