Do not apply one fee rate
The Prom.ua result varies by category, market, campaign and service. Use the actual deduction line and divide it by the matching sales base.
This produces an effective period fee that can be compared with plan and prior periods.
Separate deductions by cause
Account for fulfillment: fulfillment depends on seller warehouse, selected carrier and payment status. It changes logistics, storage and return-related lines.
- selling fee
- handling, delivery and reverse logistics
- storage, receiving and optional services
- penalties, reimbursements and adjustments
Compare like-for-like conditions
The Prom.ua focus includes merchant storefronts, catalogs, orders and multiple delivery carriers. Compare SKUs within the same category, market and fulfillment model.
A higher deduction share may come from price, returns, dimensions or paid-service usage rather than a rate change.
Weekly control list
Flag products whose effective deduction share moved beyond the allowed threshold and trace the change to source lines.
Do not keep rates as permanent constants: tariffs change, while the actual report remains the verification source.
