About MopMargin
MopMargin is a developing resource for small commercial-cleaning contractors who want to explain the assumptions behind an office bid.
The site publishes input-based calculators, practical instructions, and clearly labeled fictional examples. It is a publisher and tool provider; it does not perform cleaning services, broker jobs, or certify that a bid will win or be profitable.
We are still assembling the named editorial and practitioner-review team. No professional credential or customer result is claimed before it can be documented.
