Quoted value against every cost — material, labour, theeka, expense — so the profit figure is the real one.
A job can feel busy and still lose money. The only way to know is to put the quoted value next to everything the site actually consumed — and most registers never do.
TameerBook builds a per-project profit-and-loss from the real figures: material and stone cost, labour and theeka, expenses and payments — and rolls it up into live cash in hand, payables and receivables across every site.
