Specialty trade contractors lose up to 20% of profit to missed change-order notice deadlines — not bad estimating. Notice Deadline Calculator tells you exactly when your claim notice is due, based on AIA A201-2017, ConsensusDocs 200, or a custom day count. Free, no signup, works as a Chrome extension or web tool.

Hey Product Hunt 👋
I built this after watching the same pattern play out across every job: work gets done, scope changes, everyone agrees verbally — and three weeks later nobody can prove notice went out in time. Most standard-form contracts only give you 14-21 days to file a claim notice. Miss it, and you can lose the right to be paid, regardless of how good the original estimate was.
This calculator is free and does one thing: tells you exactly when your notice is due, based on your actual contract terms.
It's a small piece of something bigger I'm building — ScopeLedger, change order and notice deadline tracking for electrical, mechanical, HVAC, and fire protection contractors. But this tool stands alone and costs nothing.
Would genuinely love feedback, especially from anyone who's actually been burned by a missed notice window.
