The farm map
Draw your fields. Attach them to the enterprises that farm them. Then read profit per acre straight off the ledger.
Fields you draw, not fields you type
Draw your field boundaries on satellite imagery. You get the shapes as they really are. Not a rectangle with a note saying "about 80 acres."
Acreage comes from the boundary you drew. So it is the real number. Not the one somebody paced out years ago that everyone has copied since.
Fields can be split, merged and redrawn as the operation changes.
Fields belong to enterprises
Each field is attached to the enterprise working it.
That link is what turns a map into an accounting tool. Once the software knows which enterprise farms which ground, every dollar coded to that enterprise has an acreage to divide by.
The link is season-aware. Ground that ran corn last year and beans this year is not one permanent assignment. The history stays intact, so last year's numbers still report against last year's crop.
Profit per acre, from the general ledger
The figures on the map are not estimates you typed in somewhere else. They come from the same ledger as your financial statements.
Revenue and cost coded to the enterprise, divided by the acres attached to it.
So the map cannot disagree with the profit and loss. If a field looks like it lost money, that is the accounting talking. You can trace it to the transactions that say so.
What it is for
This is a financial map, not an agronomy platform.
It does not do prescriptions, soil sampling, yield modeling or variable rate. There are good products for that. This is not trying to be one.
It answers a narrower question, and most of those products cannot: which ground actually made money, and how do you know?
