Ask Atrium
“Which recurring items increased the most this month?”
Plain-English answer in seconds
Supplier prices change one invoice at a time.
No single delivery looks wrong. The increase is only visible against what the same item cost the last time it arrived. That is the comparison Atrium keeps for you.
Half & Half Creamer, one case
The same item, the same supplier, three deliveries.
- May$41.95First delivery on this invoice line
- July$46.95Up $5.00, flagged for review
- August$50.79Up a further $3.84, flagged again
+21% in three months on one recurring line.
Supplier prices can drift before anyone notices.
Hotel teams buy the same items again and again: towels, gloves, coffee, cleaning chemicals, paper goods, breakfast supplies, amenities, bulbs, and maintenance parts. When a supplier raises the price by a few dollars per case, pack, or unit, it may not look dramatic on a single invoice. But across recurring purchases, multiple departments, and multiple properties, those small changes can quietly become real margin pressure.
- Recurring items increase in price without being reviewed.
- Case, pack, and unit pricing make comparisons confusing.
- Managers see invoice totals, but not product-level changes.
- Supplier price increases are discovered after month-end.
- Similar items are purchased from different suppliers at different prices.
- Operators lack a clean view of price movement across properties.
What is supplier price drift?
Supplier price drift is the gradual change in what your hotel pays for recurring items over time. It can happen when a supplier raises a unit price, changes a pack size, adds fees, substitutes a product, or sells a similar item under a different SKU. Atrium reads invoice history line by line so hotel teams can see what changed, when it changed, and what may be worth reviewing.
Unit price changes
Track when an item increases from $18.50 to $22.75 per case, pack, or unit.
Pack-size changes
Normalize case, box, pack, each, pound, kilogram, and unit pricing for cleaner comparisons.
Monthly impact
Connect price changes to purchase frequency so teams can understand the potential cost over time.
Find out which suppliers changed prices.
Forward 10 recent supplier invoices. Atrium analyzes recurring items, unit prices, pack sizes, supplier changes, and invoice history to show where prices may be drifting.
No supplier switch required. Start with the invoices you already receive.

The Atrium procurement network
Once the billing is right, the network shows you what else is possible.
Contract compliance answers whether you were billed correctly. The network answers a second question: whether the rate you agreed was the right one in the first place.
Atrium connects products, pack sizes, suppliers, agreements and pricing into a procurement graph, so comparable products and alternative suppliers surface from invoices you already sent.
Connected intelligence. Your hotel’s data stays private.
