Monitoring duty-free tenant sales for anomalies
“Rent is calculated from the sales the tenant reports.”
Problem
Many partner companies operate stores in the airport’s duty-free zone. Rent is set as a percentage of store sales, so the sales a tenant reports are the basis of the corporation’s revenue. The integrity of those reported figures relied on after-the-fact sample checks.
- No transparency — no standing way to verify under-reporting
- Scattered data — split by tenant, store, item and period, so cross-checking is hard
- No full coverage — manual sample checks cannot cover everything
What BeSir did
Turn sample checks into continuous full-coverage monitoring, and establish the evidence needed to detect and recover rent lost to under-reporting.
- Monitors each partner store’s sales data continuously
- Detects deviations from patterns across stores, items, periods and comparable stores, and presents them to staff with the evidence
- Structures the judgment criteria as an ontology so the same standard applies regardless of who reviews
- Moves from sample checks to full coverage
Targets
