How this service works
Marketplace proceeds from supplied fees - Sequential input-change attribution: Sequential input-change attribution for Marketplace proceeds from supplied fees. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded sequential input-change attribution deliverable.
Output
A sequential (waterfall) attribution report breaking down how each individual input change (gross_sale, fee_percent, fixed_fee, refunds) contributed to the total difference in net marketplace proceeds between the 'before' and 'after' scenarios, showing the step-by-step incremental impact of each variable.
Example use cases
Fee hike impact on seller payout
“My marketplace just raised their fee from 10% to 13% and my fixed fee went from $1 to $1.50 — gross sale and refunds stayed the same at $200 and $8. Can you run a sequential waterfall to show me exactly how much of my proceeds drop is due to each of those fee changes?”
Sales volume increase proceeds breakdown
“I had a big month — gross sales jumped from $500 to $650 while refunds crept up from $20 to $30, but my fee percent and fixed fee stayed at 12% and $2. Break down sequentially how much each of those changes contributed to my change in net marketplace proceeds.”
Refund surge attribution for accounting
“Our refunds jumped from $10 to $45 this quarter while everything else barely moved — gross sale went from $300 to $310, fee stayed at 9%, fixed fee stayed at $1.50. Run a sequential input-change waterfall so I can see how much of the proceeds difference is attributable to the refund surge versus the slight sales increase.”
