You negotiated the deal. Atrium makes sure it sticks.
Confirm the supplier terms once. Atrium checks every invoice that follows and surfaces pricing or charges that don’t match.

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.
Price intelligence
One hotel. Six months of invoices. 20 minutes.
22
supplier price increases surfaced
13.7%
average increase
Atrium reconstructed item-level price history from the hotel’s existing invoices and found 22 recurring products whose prices had increased.
One of the clearest examples
House blend coffee
$160.50 → $211.69 +31.9%
The hotel didn’t need a new purchasing process or supplier integration. The changes were already sitting inside invoices it had received.
What this showed
Small supplier increases can accumulate invoice by invoice without ever appearing as one obvious event.
Agreement compliance
One supplier agreement. Five weekly invoices.
The same two incorrect charges appeared every week.
10
contract exceptions
$118.15
billed outside the reviewed terms
Atrium converted the supplier agreement into reviewed pricing rules, then checked each incoming invoice against them.
Supplier agreement
reviewed terms- Invoice 12 exceptions
- Invoice 22 exceptions
- Invoice 32 exceptions
- Invoice 42 exceptions
- Invoice 52 exceptions
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 non-compliant charges continue unnoticed.
Different problems. Same purchasing history.
Price intelligence tells you when supplier pricing changes. Contract compliance tells you whether the pricing and terms you negotiated are actually being honoured.
Atrium keeps checking as new invoices arrive.
Findings surfaced for review; they are not presented as recovered savings unless the hotel confirms a credit or adjustment.
You read the agreement once. The invoices arrive every week.
A signed agreement gets filed. The invoices it governs keep coming for years, and each one is paid against the purchase order, not the terms. Atrium holds the agreement open beside every one of them.
Your AP system knows what you paid. Atrium knows whether you should have.
Accounting and AP tools are built to capture an invoice, route it for approval, and record the payment. They do that well, and Atrium does not replace them.
What they generally do not do is hold the supplier agreement open beside the invoice and compare it line by line, every time. The agreement is a PDF in someone’s inbox; the invoice is a number that matches the purchase order. Both can be true while the rate is wrong.
Your 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.
- Fixed contract pricingThe agreed rate per item, per pack, per unit.
- Percentage increase capsA 5% annual cap, held to 5%.
- Effective and expiry datesTerms applied only while they are live.
- Size and product premiumsUpcharges that are supposed to be covered.
- Service chargesLine-item fees added beside the goods.
- Replacement valuesWhat a lost or damaged item may be billed at.
- Recurring rental and service feesThe weekly charge that never stops.
- Duplicate and repeated chargesThe same line, billed twice.
- Invoice price driftA rate that moves without an agreement to match.
Not a black-box alert. Every finding shows the evidence behind it.
You are going to take these findings to a supplier. That only works if you can point at the clause, the line, and the invoices it repeats on — so that is what an exception opens with.
- Contract termThe clause and rate Atrium is holding the invoice to.
- Invoice lineThe billed line exactly as it arrived, not a summary.
- VarianceThe difference, per unit and extended.
- Affected invoicesEvery invoice carrying the same exception.
- Estimated impactWhat the repetition adds up to, stated as an estimate.
One property notices a rate. A group notices a pattern.
The same supplier, the same line, the same terms, billed the same way at four hotels that never compare invoices. Atrium checks each property against its own agreement, then shows the group what they share.
The same supplier, breaking the same terms, at every property.
One property finds a rate billed above its agreement. A group finds that the same supplier is doing it at four hotels, on the same line, against the same signed terms.
Atrium checks each property against its own agreement and then gathers the exceptions into one view, so a pattern that is invisible per-hotel becomes a single conversation with the supplier.

Harbourview is paying 18% more for a comparable housekeeping item than Riverside.
Surfaced once invoices from both properties land in Atrium.
See where:
- supplier pricing differs across properties
- prices moved over time
- the same supplier behaves differently across locations
- purchasing has fragmented across the portfolio
- supplier concentration is increasing
- a commercial relationship deserves attention
Comparisons cover similar products and items Atrium can confidently match. Where pack sizes or specifications differ, properties are reported separately rather than presented as like-for-like.
See portfolio intelligenceThe same invoices answer more than one question.
Contract compliance is the job Atrium is bought for. Everything below runs on the purchasing history it builds along the way — price movement, comparable suppliers, and plain-English questions over the whole record.
The Atrium procurement network
Once the billing is right, the network shows you what else is possible.
Contract compliance answers whether you were billed correctly. The network answers a second question — whether the rate you agreed was the right one in the first place.
Atrium connects products, pack sizes, suppliers, agreements and pricing into a procurement graph, so comparable products and alternative suppliers surface from invoices you already sent.

Atrium is building the reportSample data. Reports cover the invoices Atrium has already received, and only the properties you are authorized to see.
Workbooks are files, not a dashboard: open them in Excel, forward them, or drop them into the finance systems you already run.
See how reporting worksAI can read a PDF. Atrium keeps watching what happens next.
A general AI tool can summarize an invoice or contract you upload.
Atrium builds an ongoing procurement record across every invoice, supplier, agreement, property and product, then uses that history every time something new arrives.
- 01
Remembers the price history
Every recurring item builds a history instead of starting from zero on every upload.
- 02
Knows the reviewed agreement
Confirmed supplier terms become checks against future invoices.
- 03
Connects supplier products
Atrium can surface comparable purchasing options from supplier catalogs instead of only analyzing what you already bought.
- 04
Keeps running automatically
Invoices can arrive by email and be checked as they come in. Nobody has to open an AI chat and ask it to analyze each document.
Start with one property, or one supplier across many.
A single hotel can start free and see what its own invoices hold. A hotel group starts with one supplier across a few properties — no account, no integration, no IT project.
