Review what doesn't match

No agreement needed. Forward your supplier invoices and Atrium puts every line in one place, with the patterns already pulled out.
Where the money goes.
Every supplier, ranked by what they billed you.
What moved.
Each item against its own history, so four small increases show up as one trend.
What repeats.
Invoices that look like one you already paid, flagged before payment.

What Atrium found in real hotel purchasing data.
Not demo data. Atrium analyzed invoices and supplier agreements hotels were already using and surfaced issues that had been sitting inside the existing purchasing history.
Agreement compliance
One supplier agreement, checked against every weekly invoice.
The same two charges, on every invoice, 14 weeks in a row.

The same two charges, every week, May to July
Most of the invoice pricing was correct. But two replacement charges that should have been covered by the agreement kept appearing on every weekly invoice.
What this showed
A supplier can broadly follow an agreement while small charges outside it continue unnoticed.
Price history
One hotel. One food distributor. December to July.
26 of 30
deliveries where a price rose
Atrium rebuilt item-level price history from invoices the hotel already had, and compared each delivery with the last time the same item arrived.
One of the clearest examples
Bottled water, per case
$11.95 → $15.99 +33.8%
$11.95 to $15.99 a case, in four small steps, December to July.
What this showed
Small supplier increases can accumulate invoice by invoice without ever appearing as one obvious event.
What the hotel did
Used this history to move its food purchasing to another supplier.
Different problems. Both were in invoices the hotels already had.
Contract compliance tells you whether the pricing and terms you negotiated are actually being honoured. Price history tells you when supplier pricing changes.
Atrium keeps checking as new invoices arrive.
Findings are surfaced for review. They are not counted as savings unless the hotel confirms a credit or adjustment.
That’s one hotel’s history. See yours.
5 invoices a month, free. No card.

Your AP system knows what you paid. Atrium knows whether you should have.
You read the agreement once. The invoices arrive every week, and each one gets paid without anyone checking it against the terms.
Where Atrium sits in hotel APYour AP system
Captures the invoice, routes approval, records the payment, and reconciles against the purchase order.
Atrium
Holds the signed agreement beside every invoice line and flags the ones billed outside it, before the payment goes out.
The terms that actually get billed against.
An agreement is not one price. It is a set of commitments, and any of them can be quietly missed on an invoice that otherwise looks normal.

Illustrative examples. Every finding opens with the same five pieces of evidence, so it can go straight to the supplier.

The same supplier, billing above the same terms, at every property.
The same line, billed above the same signed terms, at four hotels that never compare invoices. Atrium checks each property against its own agreement, then shows the group the pattern as one conversation to have with the supplier.
Audit one supplierThe same invoices answer more than one question.
Contract compliance comes first. The same invoices also show where prices moved.
