For shops that build one at a time

I built this for my own guitar shop.

Price list, schedule, invoices, books. One place, and they all read the same numbers.

Schedule

Move one build up. Everything behind it moves.

Nothing here is placed by hand. It is worked out from the queue, your pace, and the weeks you are shut.
