Ask Atrium
“Which recurring items increased the most this month?”
Plain-English answer in seconds
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.

The kind of price changes Atrium can surface.
Atrium does not just show that spend went up. It helps explain why.
Recurring item increase
Nitrile gloves increased from $18.50 to $22.75 per case. Based on average monthly usage, this may add $59.50 per month.
Supplier-wide movement
Guestroom amenities from one supplier increased across 8 recurring items this month.
Pack-size mismatch
