6The paperwork
Your procurement data is already there. It’s just disconnected.
Contracts, price lists, purchase orders, goods receipts, invoices and supplier emails all arrive separately. Atrium connects the documents your team already works with so it can understand what you agreed to, what you ordered, what arrived and what you were billed.
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. Your accounting system records the bill. Atrium understands whether the bill is right.

Your accounting system records the bill. Atrium understands whether the bill is right.
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. Atrium continuously turns procurement issues into a prioritized work queue, with the evidence your team needs to act. 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 what your hotel pays for recurring products and builds a pricing history across suppliers and properties — so the increase surfaces 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.

One invoice, all the way through
Forward the invoice. Atrium does the rest until something needs you.
Sample invoice. Hover or tap a stage to hold it.
What runs on every invoice, in order.
No integration to build. No software to install. Nothing migrated off the system you already run. Your team keeps ordering, receiving, and paying exactly the way it does today — Atrium picks the paperwork up from there.
Forward the email
Send supplier invoices to your Atrium inbox, or set one inbox rule and forget it. PDFs, scans, phone photos, spreadsheets, and plain-text emails all arrive the same way.
Atrium reads every line
Supplier, invoice number, invoice date, due date, products, SKUs, quantities, unit prices, taxes, fees, totals, category, and department. Line level, not just the header total.
Deterministic rules run the check
The 3-way check compares what was ordered, what arrived, and what was invoiced. The rules are fixed and repeatable, so the same invoice produces the same result every time.
Only mismatches reach a human
Lines that agree clear quietly. A price that moved, a case that never showed up, a bill that already came through last month — those land in the exception queue with the evidence attached.
The same four steps run the free first report on the hotel invoice audit page. Ten invoices, no card, no commitment — you see what the platform finds on your own paperwork before anyone talks about a subscription. In one pilot hotel, the first report read six months of invoices and found 22 price increases averaging 13.7%, in 20 minutes. The figures further down this page are the same property eight months later.
One delivery, three documents, two disagreements.
This is the whole product in one card. The purchase order, the goods receipt and the invoice for a single delivery, side by side — and the two lines where they stop agreeing.

Ordered, arrived, invoiced — checked together.
The 3-way check runs on every delivery. Line items, quantities, taxes, and totals are compared against the purchase order and the goods receipt, so accounting sees only what needs their eyes. Hotels with negotiated rates can also have covered lines checked against their supplier pricing agreements, and recurring bills are screened for duplicate invoice risk before a second payment goes out.
- ✓Line-by-line match against the originating PO and goods receipt
- ✓Mismatches flagged with the amount and the reason
- ✓Accounting-ready exports in PDF, Excel, and CSV

The paperwork keeps arriving. Somebody still has to check it.
Front desk, housekeeping, kitchen, maintenance — invoices reach a property from every direction and each one is somebody's afternoon. Atrium reads them in one place, before anyone signs off on a payment.
Every way money leaks before you pay.
Prices that crept up. Deliveries that came up short. Bills that arrived twice. Atrium sorts each forwarded invoice into eight kinds of exception, and every one arrives with the line, the amount, and the reason it surfaced.

Atrium
3-way check
None of these are accusations. They are lines worth reviewing, with the arithmetic attached so a supplier conversation can start from a fact rather than a hunch — the team decides what happens next. Two of them get their own deep dives: supplier price drift and duplicate invoice detection.
Everything a purchase manager actually touches.
Pack-size normalization
A 4L jug and a case of six compared on the same unit, so a cheaper option is actually cheaper.
Operator rollup
Suppliers, departments, and exceptions across every property in the group, or kept siloed per GM.
Role-aware access
Housekeeping sees their orders. Purchase managers see everyone's. Controllers see the exports.
Spend trends
Every dollar, every department, every supplier, month over month — without a report builder.
Contract compliance
Upload a supplier pricing agreement and covered lines get checked against the reviewed rate.
Built for hotels
Departments, approval chains, and export shapes that match how hospitality actually runs.
Accounting-ready exports
PDF, Excel, and CSV downloads coded by supplier, category, and department. Your GL does not move.
No setup
Forward an email. No integration to build, no install, nothing migrated, no re-keying.
Five people open Atrium for five different reasons.
A hotel does not have one procurement person. It has an owner watching the portfolio, an operator comparing properties, a GM defending a monthly budget, a controller closing the books, and a purchasing manager on the phone with a rep. Each of them sees the same invoices from a different angle.
Owners
See where spend may be leaking across the business.
One view across every property, without asking five GMs for five spreadsheets. Price increases, duplicate risk, and comparable-supplier options roll up to the same place.
Operators
Compare suppliers, properties, departments and invoice activity.
The operator rollup puts the whole group on one screen. If one property pays more for the same case of coffee than another, the difference is visible instead of buried.
GMs and AGMs
Catch budget pressure and supplier changes before month-end.
Budgets update as invoices land, not after the close. A department running hot in week two is still a decision — in week five it is only a variance to explain.
Controllers and finance teams
Review duplicate risk, due dates, outstanding invoices and cleaner AP data.
Coded, line-level data arrives before the payment run rather than after it. Exports come out as PDF, Excel, and CSV downloads, coded and ready for the ledger you already keep.
Purchasing managers
Track recurring items, supplier pricing and items worth renegotiating.
Every recurring item carries its own price history. When a rep says nothing changed, the line item says otherwise, and the conversation starts from the number.
Groups running more than one property get a rollup across all of them — the details live on the multi-property hotel spend management page.
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.

Nothing gets switched off. A few habits get retired.
Atrium does not replace a system. It replaces the manual checking that nobody has time to do properly — the spot-check, the remembered price, the reconciliation that happens after the money is gone.
QuickBooks records the bill. Atrium checks whether the bill is right.
Nothing is migrated. Nothing is switched off. Your ledger stays exactly where it is, and Atrium sits one step earlier — between the invoice arriving and the payment going out.
The two jobs are genuinely different. An accounting system is a system of record: it books the invoice, tracks the payable, and closes the month. It does not know that the case of house blend coffee used to cost less, or that the same carton of pillowcases was billed on two separate invoices.
Atrium answers that question first, then hands the result over. Exports are accounting-ready file downloads in PDF, Excel, and CSV, coded by supplier, category, and department. There is no write-back integration and no plugin — your controller downloads a file and works the way they already work.
Teams coming from a manual AP process usually start on the hotel AP automation page, which covers the approval and payable side in more detail.
Eight months of invoices at one Niagara Falls hotel.
Not a demo dataset. One property forwarding invoices from eight suppliers — broadline foodservice, guest amenities, maintenance supply, coffee, dairy, and beverage — from December 2025 through August 2026. These figures accumulated across eight months of ongoing use, one forwarded invoice at a time.

The sharpest line
House blend coffee went from $160.50 to $211.69. A 31.9% increase that nobody announced.
Across the eight months, the 24 increases ranged from 5.1% to 31.9%, with a median of 11.1%. The fees moved too: a bottle fee went from $2.00 to $6.00 and a fuel surcharge went from $7.00 to $12.00, a 71.4% jump on a line most people never read.
The same two lines, every week
At another property, a uniform rental agreement leaked $23.63 a week from two mops.
One agreement with a 5% annual cap and 38 agreed line items. Across five weekly invoices totalling $5,204, Atrium surfaced 10 violations worth $118.15 — and it was the same two lines each week: a large wet mop billed at 5 x $2.00 and a 20-inch microfiber mop billed at $13.63, both covered by the agreement as free replacement up to a stock percentage. See hotel contract compliance.
Ten spend anomalies surfaced over the same period, two of them critical. Every one of those numbers is a line worth reviewing, not a refund collected — Atrium flags them and the hotel decides what happens next.
What Atrium deliberately does not do.
A review layer is only useful if you can trust where it stops. These are not roadmap gaps — they are deliberate limits, and they are worth knowing before you forward the first invoice.
Atrium never moves money
No payment rail, no ACH, no card on file. Atrium surfaces the exception with the evidence attached, and the approval and the payment stay entirely with your team. Your call, every time.
Atrium does not switch suppliers for you
A comparable-supplier option is a suggestion with the arithmetic shown. Your relationships, contracts, delivery windows, and volume commitments are yours to manage — the software has no opinion about who you buy from.
Atrium is not a formal accounting audit
This is an operational spend and exception review. It checks invoice facts against orders, receipts, and reviewed agreements. It does not opine on financial statements, provide assurance, or replace your accountant.
A person confirms agreement terms first
AI reads the supplier pricing agreement and structures the rates, dates, and caps. A human confirms those terms before a single rule runs against them, and any line without a confirmed rate stays in review rather than being called a breach.
