• Build three fixed packages

  build_packages

  Turn the work a service business does into three fixed-price packages (smallest, middle, largest). Takes the cost base (fixed costs, owner pay, staff, delivery capacity) and the deliverables the business offers, each marked core (every client needs it), common (most clients want it) or premium (some clients want it), with its typical effort and direct cost. Returns each tier with what it includes and leaves out, its cost, break-even price, target price, a recommended price rounded up to a clean number, margin and profit per sale, how far the work can overrun before the margin hits zero, and a capacity check: hours needed, break-even clients a month, and the month profit after owner pay. All results are deterministic arithmetic with the method explained. Adjustments to what was built are treated as included, so effort carries a variance buffer.
