The hours that stay human: estimating Drupal work when AI writes the code

When AI writes the Drupal code, the hours move to checking and fixing its work. I'll share what changed in how I estimate AI-built Drupal work, so you can quote with numbers you can defend.

Has anyone asked you this yet? "AI writes the code now, so why is the estimate still so big?" This talk is my answer.

I write presales estimates at QED42. This year I changed how I estimate work that an AI agent builds and a person steers, checks and fixes.

What I learned:

  • AI saves a lot of time on some Drupal tasks and very little on others. A flat "AI discount" gets it wrong both ways.
  • Some AI mistakes show on the page. Others stay hidden until a client finds them. Work where mistakes hide keeps most of its hours.
  • AI-built projects carry costs that sit outside every task. Leave them out and you under-quote.
  • My first estimates were too optimistic. Checking them against real work fixed that.

What I'll cover:

  • How to tell which Drupal work speeds up with AI, and which doesn't
  • The costs people forget when they estimate AI-built work
  • How to check an estimate against real logged hours
  • How to explain AI savings to clients without crashing your own rates

You'll leave with the questions to ask before you put an AI discount on your next estimate.
