work-order variance

This worksheet makes work-order variance explicit from the exact figures you enter. Review the period and basis of every amount before comparing results.
Use a conservative scenario as well as the base scenario; the calculation describes assumptions rather than predicting behavior.

The assumptions that move this result

Budget
Approved work-order amount.
Invoice

Formula
vendor invoice + materials − approved budget

Built by a landlord who's done every one of these jobs by hand.
Aptoria was built by an owner-operator managing a Brooklyn portfolio — the 11pm calls, the awkward rent texts, the April receipt-pile — not by a software team guessing at the problem.
