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.
See the rate, invoice, and variance together.
The reviewer does not have to find the agreement or rebuild the arithmetic. Atrium keeps the applicable term and invoice calculation connected.
- Applicable agreement selected by supplier and date

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.
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.
