AtriumCatch hotel invoice exceptions before payment.
Atrium compares what was ordered, what arrived, and what was invoiced. Price mismatches, short deliveries, and duplicate invoices get flagged before money leaves.
Start with 10 recent invoices. That’s it.
7The mailroom
Every review starts where invoices arrive.
Forward supplier emails, PDFs, and spreadsheets, or set up an inbox rule once. Atrium reads each document and extracts the supplier, items, quantities, and unit prices. No re-keying, no uploads.

6The paperwork
Hotel spend leakage hides between the paperwork.
Purchase orders, goods receipts, packing slips, and invoices arrive separately. Atrium matches them to each other automatically, so every invoice is connected to what was ordered and what actually arrived.
Purchase orders, receipts, and invoices live in different places.
Receiving teams know what arrived, but finance sees the invoice.
Supplier prices can change without being reviewed.
Invoices can bill for items that were short on delivery.
Duplicate invoices can slip through busy inboxes.
GMs and controllers often see issues after month-end.
Accounting records the bill, but does not always show whether the bill is right.
5The 3-way check
Before accounting, check if the bill is right.
For every invoice, Atrium runs the 3-way check: what was ordered, what arrived, what was invoiced. Every line, every quantity, every unit price. QuickBooks records the bill. Atrium checks it first.

QuickBooks records the bill. Atrium checks whether the bill is right before you pay it.
4Exceptions surface
Only the exceptions surface.
Matched lines clear on their own. Atrium queues only the mismatches: a price that jumped, a quantity billed but not received, an invoice that looks like a duplicate. The team decides. No payment ever moves automatically.

3Price watch
Supplier prices creep when nobody’s watching.
Price increases happen one invoice at a time. Atrium remembers every recurring item’s unit price and flags the increase before the next order, not after month-end.
Catch supplier price drift early
Atrium tracks every recurring item's unit price across your invoices and flags increases before the next order.

Your invoices already know. Ask.
Because every document is structured and connected, you can ask in plain English: which suppliers raised prices, which items were billed but not received, which invoices need review. The answers are already there.

See what needs review before payment.
Start with 10 recent invoices plus any related purchase orders or goods receipts. Atrium will show what was ordered, what arrived, what was invoiced, and what needs review before payment.
If you only have invoices, Atrium can still surface price drift, duplicate invoice risk, spend spikes, supplier concentration, and recurring item changes.
From one pilot hotel
In one pilot hotel, Atrium reviewed 6 months of invoices and found 22 price increases averaging 13.7%. It took 20 minutes. No integrations. Only invoices.
Start with 10 documents. For deeper price and supplier patterns, 30–90 days of invoice history gives the clearest report.
Tag, code, and discuss every order, as a team.
Atrium turns each forwarded invoice into an order your team can work on together. Leave notes, code spend with labels like capex, and assign departments. Every order gets reviewed and coded before payment.

Send cleaner data to accounting.
Atrium is not an accounting replacement. Hotels can keep QuickBooks, Sage, Xero, M3, NetSuite, or their existing finance workflow.
Atrium checks the purchasing documents first, so accounting receives cleaner, reviewed invoice data.
The capture, matching, and structuring are automated. The decision to pay stays with your team.
