The MarginMine method
One audit method. Built into focused products.
The interface changes with the cost category. The underlying discipline does not: connect the source, rebuild the charge and preserve the evidence.
Animated source reconstruction
Trace the charge. Not just the anomaly.
Invoice, operation and agreement meet in one reproducible calculation path.

The company layer
Built as a product portfolio, not a one-off parcel tool.
Parcel Audit is the first focused product. The shared MarginMine method—source linkage, deterministic reconstruction and evidence design—can later support other operational cost categories without pretending they already exist today.
