I think that the hardest part of implementing this project is that it is not a DIY, like the lab sub was, after the initial design. And how do we compensate the person(s) doing the work.
That said, I'm all in. My requests:
1) In the version of Quickbooks that I now have I like being able to do an estimate, and then if it comes to fruition, change it into an invoice. I would like something similar here. Maybe something calender based that would warn you if you have proposals pending that might cut into your inventory.
2) In making bids I would like to be able to drop in single pieces, subsets (like a speaker system, or amp rack), or entire systems. I would also like to be able to save systems, like a known system for a certain customer or performer.
3) I would like to be able to bid by my own algorithm. IE, for me I usually do it by labor, gear, and expenses. So an edit screen where you can choose what items come up for bidding.
4) A labor pool to choose from, and drop in. Again calender based, maybe one that is interactive online so subcontracted labor can let you know if they are available or booked.
Good luck, Jack Arnott
