Hotel invoice & procurement glossary.
Plain-English definitions of the terms behind Atrium — what they mean, why they matter for hotels, and how they fit into reviewing invoices before payment.
3-way matching
3-way matching compares the purchase order, the goods receipt, and the supplier invoice so a hotel only pays for what it ordered and actually received.
Billed but not received
Billed but not received means a supplier invoiced for more units than the hotel actually received — paying for goods that never arrived.
Goods receipt (GRN)
A goods receipt note (GRN) records what was actually delivered — the proof a hotel checks an invoice against before paying.
Invoice capture
Invoice capture turns supplier invoices — PDFs, scans, photos, and email attachments — into structured, line-item data a hotel can actually use.
Invoice exception
An invoice exception is any supplier invoice that doesn't match what was ordered or received — a price change, short delivery, duplicate, or missing detail.
Pack-size normalization
Pack-size normalization converts case, box, and each pricing to a common per-unit basis so a hotel can compare prices fairly across suppliers.
Purchase order (PO)
A purchase order is the hotel's record of what it agreed to buy and at what price — the baseline every invoice should be checked against.
Spend leakage
Spend leakage is money a hotel loses to small, unnoticed invoice errors — price creep, duplicates, and short deliveries that add up over time.
