Net Profit per Order: A Simple Ecommerce Framework
Build a repeatable net-profit-per-order view you can reuse across channels, promos, and fee changes without rebuilding spreadsheets each week.
Published: 2026-04-24
One equation, many channels
Net profit per order should use the same cost stack everywhere: price, COGS, outbound logistics, marketplace or payment fees, ad allocation, and reserves.
Cadence that keeps models honest
Weekly for ads-heavy brands, monthly for stable catalogs. Update when carrier contracts, fee tiers, or return rates move meaningfully.
- Snapshot median and P75 order values, not only average
- Track promo weeks separately from steady-state weeks
Leadership view
Roll up SKU-level order economics to collection-level only after each SKU is sane. Bad rollups hide loss-making heroes subsidized by winners.
