The difficulty with this sort of thing, in my experience, is that once you do need to hire a lawyer to review this sort of agreement, it turns out to be a lot more expensive in the long run than just hiring them and using their forms to begin with. They know their own language backward and forward so it takes them very little time to make a standard change to their standard form. Looking at an entirely new (to them) agreement, they have to analyze it from scratch.
If there were truly industry-standard forms that all attorneys were familiar with for these standard agreements, that difficulty wouldn't arise. That's how the residential real estate market in the US works, for example — standard forms for all sorts of situations approved by the real estate associations. It's sort of like how an open source infrastructure product will eventually become the cheapest thing to use because everyone already knows how it works.
Do you have a goal/roadmap for making your agreements the industry standard?
