One example from the Dovrin portfolio: a real, working tool that prices a statement of work line by line — cost, price, and margin, recalculated on every keystroke, with hard guardrails before anything ships to a client.
This is the kind of tool Dovrin builds: small in scope, exact in its numbers, and honest about the line it won't let you cross.
Cost, price, and margin recalculate as line items change — no "run the report" step, no stale numbers while a deal is being shaped.
Any deal that drops below its margin floor is flagged immediately. A hard STOP blocks sign-off outright — it won't quietly let a bad deal through.
Rate cards are versioned, not overwritten. A past estimate never silently restates itself when rates change later — every quote stays pinned to what it was built on.
One export strips cost and margin for the client's eyes; the other keeps the full internal breakdown. The same estimate, two honest views.
Every total is checked against the source pricing model — no rounding drift, no "close enough." If the model says a number, the estimator matches it exactly.
This is the actual estimator running at /swet/ — not a screenshot. Use the button to open it full-page, or try it inline.
Small, exact, and governed by rules that don't bend under deal pressure — the same discipline behind the governed-write engine for M3.
