Highlight shortages on a job at quote stage
A button, maybe opens up a smaller window like show picker which lists all the availability of the kit on the quote - this would be much quicker than going via the drop down on each individual item.
Basically something that highlights potential shortages whilst the job is still at quote stage, avoiding problems later on when the kit is converted.
Mark a quotation as reserved to reserve stock. Current will flag any shortages in red, just like an order.
Mark as provisional to mark the kit as “quoted for” again.
