Buyer's guide
How to choose AI estimating software
The short answer
Pick the tool that measures from the drawing, shows you where every number came from, prices for your area and finishes the job with a proposal. Test it on a plan set you have already bid and compare it with your own numbers.
Seven questions to ask
- Does it measure or estimate? Ask how a wall length is found: from the PDF geometry, or by eye.
- Can I check every number? Each row should link to a mark on the sheet.
- Where do prices come from? Local, sourced rates beat a model's memory.
- Does it read wall types and heights? Full-height partitions are where generic tools under-count.
- How do plans get in? Bid boards and email save the download-and-upload loop.
- What happens with an addendum? Re-measure and re-price only what changed.
- What comes out? Quantities alone, or a priced proposal your client can sign.
Run a fair test
