make your own spread sheet and fly by the seat of your pants when necessary.
any cookie cutter software does not take into account your customers, your market, and fluctuations in your business.
pricing is so incredibly dynamic that to shove it into a box solely is a major mistake to any sign business.
if you are detached from your business enough to not know your inflow, and more importantly your outflow of cash (aka your cost of materials, nut, etc.) thus leading to you not being able to set your pricing for yourself and those around you that handle that capacity, a shoe box sign pricing solution for your business is the least of your worries.
the title of this thread speaks volumes.
