I realize you're opening yourself up to criticism if you answer this truthfully, but since suppliers are your primary user (and therefore paying customers I assume?) your pitch is "supplier, you can do more with less (or no!) people when specifying material quantities, and in fractions of a second as opposed to the minutes/hours it takes today!" So, ultimately, if the suppliers fully trusted your solution they would need zero personnel determining quantities? And since your solution's annual licensing cost would likely be a fraction of the price of even a single individual that'd be pretty compelling to the supplier.
Best of luck with the business (and with getting to know the corp dev people at Autodesk/Procore/etc.--sorry, couldn't help myself!).

You'd still need people to check what actually got installed, so that you can bill for it. Like, there's only so much you can determine off the plans.
And what happens if (when) the plans are wrong or impractical?
My Dad worked in construction for his career, and I did briefly, and there's generally a lot of stuff that needs to be figured out on site due to physical or logistical constraints.
Sounds like this is just for homebuilding though, which is a much easier problem.
