Check every covered invoice against the supplier agreement.
Upload reviewed supplier pricing terms and forward invoices as usual. Atrium checks supported rates, effective dates, and price caps, then surfaces overages and unsupported lines before payment.
AI extracts the agreement. Your team confirms the terms. Deterministic rules check each covered invoice line.

A negotiated rate only creates value when the invoice follows it.
Supplier agreements receive attention when they are signed and often little attention when recurring invoices arrive. Atrium turns reviewed pricing terms into operational checks that run on each covered invoice.
The agreement is separated from the invoice
Rates sit in PDFs, email threads, addenda, and schedules while invoices arrive in a different workflow.
Small differences repeat quietly
A few dollars above an agreed rate can look harmless on one line and become material across recurring deliveries.
Review depends on memory
Hotel teams should not have to remember every SKU rate, effective date, premium, and cap before approving a bill.
From supplier agreement to invoice-line check.
AI removes manual data entry. Human confirmation and deterministic comparisons keep the result grounded in terms the hotel reviewed.
Upload the agreement
Add the pricing agreement or supported addendum your hotel wants to monitor.
Review the extracted terms
Confirm the structured rates, dates, caps, SKUs, and supported modifiers.
Forward new invoices
Keep the hotel's existing forwarding or document-upload workflow.
Check covered lines
Rules select the applicable agreement and compare each supported rate.
Review the evidence
Matches clear; overages and unsupported lines surface for investigation.
Monitor commercial terms that appear on recurring invoices.
Atrium only treats a term as enforceable after extraction and approval. If a line cannot be matched to a supported term confidently, it stays in review.
Fixed unit rates
Compare the billed price with a reviewed agreement rate, including supported sub-cent rates.
Effective and expiry dates
Apply the hotel-specific or group agreement governing the supplier on the invoice date.
Price-increase caps
Check supported product lines against a confirmed baseline and simple percentage cap.
Size premiums
Recognize supported special-size premiums so a correct charge is not falsely flagged.
Replacement values
Compare supported lost or replacement charges with the reviewed rate for that SKU.
Service and program rates
Check supported recurring service, rental, or program lines carrying their own rate.
The same two lines, five weeks running.
A hotel loaded one uniform rental agreement and forwarded five weekly invoices. A large wet mop, billed. A 20-inch microfiber mop, billed. Both are items the agreement covers as free replacement up to a stock percentage — and both appeared on every single invoice.
Ten violations. $118.15 across five invoices. About $23.63 worth reviewing each week, from one supplier at one property, on a line nobody would question in isolation.
- Standard Rental Service Agreement, 38 agreed line items, 5% annual cap
- Five consecutive weekly invoices, $5,204 in total
- 10 violations worth $118.15 — the same two lines every week
- Each exception carries the credit worth requesting from the supplier
- Atrium requests nothing. The team decides.

Credit to request from the supplier
Send one agreement and the invoices that go with it.
Forward a supplier pricing agreement and 10 recent invoices from that same supplier. Atrium returns a free Hotel Spend & Exception Report showing which covered lines match the reviewed rate, which came in above it, and which need a term confirmed.
That is the whole setup. Forward an email — no integration to build, no software to install, nothing migrated out of the accounting system your team already uses. In one pilot hotel the first report came back in 20 minutes.
Get a free Hotel Spend & Exception Report$0. One time. No card, no commitment, and no obligation to do anything with what it finds.
- Which covered lines match the reviewed rate
- Which covered lines came in above the agreed rate
- Which lines still need a term confirmed before anyone relies on them
- Whether an increase sits above the agreed cap
- Which charges appear for items the agreement treats as included
- What each variance is worth per unit and per invoice
- Which exceptions repeat on every invoice from that supplier
A missing match is not automatically a contract breach.
Contract monitoring must be trustworthy enough to support a supplier conversation. Explicit states keep uncertain or unsupported lines from being presented as proven overbilling.
The billed rate follows the reviewed term.
The line is verified against the active agreement.
The billed rate exceeds the applicable term.
Atrium shows the agreed amount, invoiced amount, and variance.
No applicable confirmed rate was found.
The line is not accused of a breach; a person confirms the correct scope.
The item appears but the charge is zero.
Shorted and out-of-stock lines remain visible without a false exception.
Designed for recurring hotel supplier relationships.
The strongest use cases combine a reviewed pricing schedule with invoices that repeat often enough for small differences to accumulate.
Keep the decision human. Remove the repetitive checking.
The agreement was signed. The invoices kept arriving.
Contract compliance is what happens next: every covered line on every invoice, compared with the terms your hotel already reviewed.
Keep every supplier you already buy from.
Atrium reads the agreements and invoices your hotel already receives, whatever format the supplier sends. Contract compliance does not ask your suppliers to do anything differently, and it does not ask your team to renegotiate anything to get started.
No supplier switch. No supplier portal. No vendor onboarding for anyone to complete.
One agreement. Several properties. One rate that should hold everywhere.
A group negotiates the rate once and then trusts every property to be billed correctly. Atrium applies the same reviewed agreement at each property under it and rolls the covered lines into one operator view.
The negotiated rate holds at one hotel. It slips at another. Nobody at either property can see the difference — the rollup can.
- Apply one reviewed agreement across every property it covers
- See which properties are billed the agreed rate and which are not
- Compare the same covered line item property by property
- Rank open agreement exceptions by what they are worth
- Track which suppliers have an agreement on file at each hotel
- Take one variance to the supplier with every property behind it
Example insight
The same covered line clears at one property and arrives above the agreed rate at another.
Surfaced when invoices from both properties land in Atrium under the same reviewed agreement.
Agreement terms and invoices in the same place.
A general manager should not have to open a folder to answer a question about a rate the hotel already negotiated. Once the reviewed terms sit beside the invoices they govern, these become things you read off a page.
Every answer traces back to a specific invoice line and the agreement term it was compared against, so a supplier conversation starts from evidence rather than an impression.
Contract compliance is one check inside a wider review.
Atrium checks every supplier invoice against what was ordered and what actually arrived, then flags the gaps before payment. A reviewed agreement adds a fourth reference point to that comparison — the rate your hotel already agreed to.
Most hotels start with a hotel invoice audit and add the agreement once they see what the invoices alone surface. The same line items also feed supplier price drift tracking, duplicate invoice detection, and multi-property spend management for hotel groups.
Exports are PDF, Excel, and CSV files your team downloads and hands to the bookkeeper. Atrium never moves money and never touches the accounting system.
Operational contract monitoring — not automated legal judgment.
Atrium checks structured commercial terms against invoice facts. It does not interpret ambiguous legal language, decide whether an amendment is enforceable, or replace the hotel's legal and procurement advisers.
