Net Profit
What's actually left after every expense — Gross Profit minus PPC, software, payroll, prep, and operating costs.
Net Profit is the bottom-line profit number after subtracting EVERY expense from revenue: COGS, Amazon fees, PPC spend, software subscriptions, payroll, prep, freight, taxes, and any other allocated costs. It's the only profitability number that actually matches what shows up in your bank account at year-end.
Most FBA sellers don't calculate net profit accurately because the costs are scattered across multiple systems: invoices in QuickBooks, Amazon settlements in Seller Central, PPC spend in Amazon Ads, software charges on credit cards, prep costs in supplier emails. SellerVault consolidates Amazon-side data, but accurate net profit still requires connecting your accounting workflow.
The gap between gross profit and net profit is where profitable-looking businesses go bankrupt. A seller doing $2M revenue at 30% gross margin has $600K of gross profit. After 18% TACoS ($360K), software and prep ($60K), and labor ($150K), net profit is $30K — 1.5% net margin. Same business, very different stories.
