AtriumStop paying invoices nobody checked.
Suppliers raise prices quietly. Deliveries come up short. The same bill arrives twice. Atrium checks every invoice against what you ordered and what actually showed up — and flags the gaps before the money leaves.
10 invoices. No integrations. Nothing to install.

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
The bill is wrong more often than you think.
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
Your team only looks at what is wrong.
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.

2Ask Atrium
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.

Nothing about how your team works has to change.
Order placed, delivery received, invoice arrives, review before payment. Atrium follows the workflow your hotel already runs — it just checks the numbers on the way through.
Every way money leaks before you pay.
Prices that crept up. Deliveries that came up short. Bills that arrived twice. Rates above what you agreed. Atrium catches each one while you can still do something about it.

3-way check
Your supplier agreement should not end in a filing cabinet.
Upload a supplier pricing agreement once. Atrium extracts the rates, dates, and price caps for your team to confirm, then checks every covered line as new invoices arrive.
Matches clear automatically. Overages and invoice lines without an applicable rate surface with the agreement term and calculation your team needs to review the charge.

AI reads the document. Deterministic rules check the bill.
Ten invoices. Twenty minutes. No card.
Send 10 recent invoices plus any related purchase orders or goods receipts. You get back what was ordered, what arrived, what was invoiced, and every line that does not agree.
Only have invoices? Still works. Atrium surfaces price drift, duplicate invoice risk, spend spikes, supplier concentration, and recurring item changes without a single purchase order.
From one pilot hotel
No integrations. No IT project. No change to how your team already works. The hotel forwarded invoices they already had, and had the 22 price increases back in 20 minutes.
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.

You do not have to rip out anything.
Atrium is not an accounting replacement. Keep QuickBooks, Sage, Xero, M3, NetSuite, or whatever your finance team already runs. Nothing gets migrated and nothing gets switched off.
Atrium checks the purchasing documents first, so accounting receives invoice data that has already been reviewed.
The capture, matching, and structuring are automated. The decision to pay always stays with your team.
