Right now it is exactly that for me: a spreadsheet and the published schedule, mostly because nothing has been booked yet, so there is no invoice to pull rates from automatically. It works for a landed cost that only exists as a quote.
What I have not worked out is whether that is a limitation of doing it by hand, or just how early-stage costing works. If nothing is booked, is there a tool that actually helps, or is a spreadsheet the honest answer at that stage for everyone?
