How this service works
Net merchandise sales - Sequential input-change attribution: Sequential input-change attribution for Net merchandise sales. 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 output that quantifies how each input change — gross merchandise sales, discounts, and returns — individually contributed to the overall change in net merchandise sales between the 'before' and 'after' states, with each driver's isolated dollar or percentage impact listed in sequence.
Example use cases
Quarterly NMS driver review
“Our Q2 gross merchandise sales were $8.5M with $620K in discounts and $410K in returns; Q3 came in at $9.1M gross, $700K discounts, and $380K returns. Run a sequential waterfall attribution so I can see exactly how much each factor drove the NMS change.”
Discount impact on revenue bridge
“We increased our discount spend from $200K to $350K this month while gross sales moved from $5M to $5.2M and returns stayed flat at $150K. Can you do a sequential attribution to show how much of the net merch sales shift was due to the discount increase versus the sales lift?”
Returns spike post-holiday analysis
“Post-holiday our returns jumped from $80K to $210K, gross sales dropped from $3.2M to $2.9M, and discounts fell from $300K to $220K. Run a waterfall breakdown to see which input had the biggest impact on net merchandise sales.”
