The sheet your AP team would build if they had a quarter to spare.

What you are buying: a monthly line-level audit of everything the portfolio pays its vendors, against the agreed prices. Locations forward their AP inboxes; you get this sheet, per-location findings, and credit-request packets per vendor. From $3,500 a month, annual, invoiced by ACH.

Every figure is generated demonstration data and stays labelled that way. Your sheet is built from your own AP during onboarding. Exports are plain CSV with stable columns.

What we report, and what we don't

Spend is compared within category and band, never across them. An electrical-supply spend and a fuel spend drift differently; comparing them directly would produce rankings that do not mean much.

REPORTED

Drift by location, vendor and category, with confidence intervals and sample sizes. Credit outcomes tracked when your AP team reports them back.

NOT REPORTED

Whether a price is fair in the market, and dispute outcomes. The audit ends at the credit-request packet; your AP teams own the follow-through.

ENTITY MODEL

Locations are child orgs under the parent; billing attaches to the parent only, by annual ACH invoice. Row-level security keeps siblings invisible to each other, tested in CI.

Portfolio pricing

Annual agreement, invoiced to the management company, paid by ACH. Priced by locations and invoice volume, not seats.
