A larger deduction total does not by itself prove that a distributor is making more errors. Start by separating changes in sales volume, planned trade activity, operational charges and reporting. Compare the same accounts and periods before drawing a conclusion.
1. Did the underlying business grow?
Compare deductions with the revenue and shipment volume that generated them. A new retailer, new distribution center or larger promotion changes the mix. Keep new-account setup and slotting separate from recurring charges so a launch does not look like a permanent increase in operating cost.
2. Did actual promotional spend exceed the plan?
Match the deductions to the retailer, promotion dates, eligible SKUs, agreed rate and units. Distinguish a valid charge on unexpectedly high volume from an incorrect rate or duplicate charge. Review deductions that arrive after the promotion's selling period rather than treating the remittance month as the event month.
Trade planning in Revya connects planned spend with the deductions that show what the promotion actually cost.
3. Are operational charges repeating?
Group shortages, damage, labeling, EDI and pricing charges by location, SKU and carrier. Check whether the same error is recurring and whether a policy or fee schedule changed. Confirm the effective version with the distributor before assuming a fee increase applies to every shipment.

4. Did the reporting change?
A new reason-code mapping, duplicate import, different date basis or previously hidden backlog can make the total jump without a new underlying event. Reconcile the deduction register to the remittances and check that credits have not been counted as new deductions.
Payment and remittance matching helps separate an unexplained balance from a documented deduction.
Build a variance bridge
Start with the prior period's deduction total. Show changes from account volume, promotion mix, new fees, one-time charges, confirmed errors and unresolved items. Use an explicit unresolved category rather than forcing every difference into an explanation.
Assign an owner to each material variance. Finance can investigate the payment and coding, sales can validate the deal, and logistics can check the shipment. Repeat the review by account and reason code so you can see whether the corrective action worked.
Measure your own opportunity
Do not apply a universal invalid-deduction percentage to the increase. Review the supporting records, quantify evidence-supported errors and keep potential disputes separate from actual repayments. The recovery measurement guide explains the denominators to use.
