GSA TDR reconciliation
IFF is a reconciliation, not only a multiplication
A defensible fee amount preserves the applicable rate, reported-sales population, exclusions, rounding and reviewer decision.
Calculation basis
Use the customer-confirmed applicable rate and the controlled reported-sales total.
Reconciliation
Compare calculated fee, ledger accrual, prior payments or adjustments and the final customer-approved amount.
Evidence
Retain the source population, rate authority, calculation output and any manual adjustment explanation.
Operational boundary: This guide explains a controlled workflow. Contract terms, permits, portal instructions and official decisions remain authoritative.
