Buying groups need a clear view of earned supplier rebates, disputed credits and the cash available for member distribution. This Excel control tower brings those records into one annual close workflow, connecting member purchases with supplier agreements, statement reconciliation, settlement receipts and actual member payments.
The workbook aggregates eligible purchases by supplier and applies retroactive volume tiers to the full eligible period volume. Qualification follows gross invoice value multiplied by the eligibility flag, less exclusions. Active membership, join dates and the reporting window determine inclusion. Signed qualification remains visible, including returns or exclusions that produce negative member spend.
Four supplied rebate brackets apply rates of 2%, 3.5%, 5% and 7%. Operating retention is 15% of earned rebates, leaving an 85% member pool before dues and signed withholding reserves. Member shares retain full precision, with monetary entitlements rounded to cents. Supplier credit differences remain separate from earned income, preserving the distinction between signed disputed receivables and actual settlement cash.
Six worksheets organize the process from Source Data through the Rebate Accrual Engine, Supplier Statements and Member Distribution to Integrity Audit and the Executive Cockpit. Fifteen business controls review purchase and statement totals, tier application, entitlements, payments, settlement conservation and source completeness. Native charts present supplier disputes and the member distribution bridge. Yellow entry areas identify source inputs.
The included fictional USD example covers January through December 2025, with 12 members, six suppliers, 24 agreement tier rows and 1,728 purchase records. Its eligible purchases total $12,542,400.00, earned rebates total $840,528.00 and actual member payouts total $708,208.80. These figures describe the example dataset.
The primary download is the Excel workbook, which contains the example purchase records. A separate documentation ZIP contains three PDFs: the seven-page Implementation Guide, the two-page Quick Start Guide and the three-page Cutover Sign-Off Template. The guides describe source ownership, onboarding, recurring close responsibilities, exception escalation and payment approval. The sign-off template provides a written close record for review.
Desktop Excel and an annual USD reporting basis are documented. The supplied calculation and control ranges have a defined capacity. Expansion requires coordinated changes to every affected source, calculation, distribution and control range, followed by reconciliation. The files support preparation and review of business records. Payment decisions require the responsible organization's review and approval.
