Six products call themselves delay or EOT tools. They do very different jobs. This page sorts them by what they actually produce, so you can pick by need rather than by whoever answered your LinkedIn message first.
Before comparing features, decide which of three problems you are buying for. Most disappointment in this category comes from buying a register when you needed a draft, or a scheduling analyser when you needed a notice clock.
You need to know every deadline on every live project and prove notices were served. Tools built for owners and project managers do this well; they rarely draft anything.
You have a Primavera programme and need to quantify critical delay for a TIA or windows analysis. This is planning-engineer software and is only useful once a claim is already being fought.
You need the narrative, the chronology, the evidence pack, and the notice letters, built from messy site records, structured for your contract family, and reviewed by an expert. This is the job DraftMyEOT does.
Descriptions and prices are taken from each product's public website as of August 2026 and paraphrased. All six companies are private and none publishes revenue or customer counts. Verify current terms directly before relying on them.

The incumbent in this category is not software. It is Excel, Primavera, Word, and a claims consultant engaged after the fight begins. Two more pages cover that comparison honestly.

The toolchain every contracts team already runs, what it does well, and the four places it loses claims. Read the comparison →
DraftMyEOT is not a law firm and never claims to be. Every output is a draft, built to be reviewed and signed by your contracts lead or consultant.
No dates, events, or clause numbers appear that you did not supply. Every paragraph shows the evidence reference it was built from.
Each company's workspace is isolated, documents sit in private storage, and consultants see only the project they were invited to.
Send a contract, your delay events, and whatever records exist, tidy or not. A structured draft comes back in 48 hours. Not useful? Keep it, owe nothing.
