A claim window is the contractually defined period after a settlement date within which a rebate claim must be filed. Once the window closes, the underlying entitlement is typically forfeit - one of the biggest single sources of contract value leakage.
Typical claim window lengths
60, 90, or 120 days after period-end is standard. Some contracts specify shorter windows; some longer. The length is negotiable but rarely renegotiated during the contract term - so the operational discipline to file within window matters more than the length itself.
The window-closure risk
Claim windows close silently. There is no natural alert unless one is built. Structured contract data with automated window tracking is what converts claim-window management from a memory dependency into an operational certainty.
