No visibility into calculation
How provisional charges were calculated was not exposed, making overlaps with standard charges hard to identify.
Client success story · CS13
Provisional and standard allowances applied to the same periods
A US industrial tools and scientific equipment brand operates under structured Vendor Central allowance agreements covering co-op, freight and damage.
The agreements were active and clearly defined, yet margins were eroding. Deductions did not match expectations, and what began as a routine audit became an investigation into duplicate billing.
Problem
At first glance the deductions appeared valid. A closer look revealed inconsistencies between sales performance and the charges applied, and then something more specific: provisional co-op charges were being applied alongside active agreements, creating a real risk of duplicate billing.
Provisional charges are normally temporary placeholders applied when standard billing is delayed. Here the timing produced overlap rather than substitution.
How provisional charges were calculated was not exposed, making overlaps with standard charges hard to identify.
Accruals, adjustments and back-charges were interleaved, so no single report showed the duplication.
Amazon's dispute policy limits how far back a claim can reach, putting a clock on the investigation.
Solution
A detailed month-by-month transaction map was built covering net receipts, allowance percentages, co-op accruals and charges, provisional adjustments and back-charges applied later.
This recreated the full billing lifecycle and located precisely where the overlaps occurred: months where standard co-op was not applied, provisional charges introduced as placeholders, and back-charges later applied for the same periods under the actual agreement.
Deductions were recalculated with and without provisional charges, duplicate entries identified at invoice level, and a clean reconciliation file prepared showing the financial impact. This converted complex data into dispute-ready evidence.
Amazon Support and Finance teams were engaged, and the Vendor Manager was brought in for agreement validation — necessary because provisional charge behaviour is not visible in standard reporting.
Impact
Allowance deductions in Vendor Central are shaped by system-driven adjustments that are not visible in standard reporting. A timeline-based audit found duplication that no single report would have shown, and the correction moved the client from reactive dispute handling toward proactive financial control.
