Your store shows revenue — not profit. ProfitVault subtracts every real cost so you know what you actually keep. For each order it computes true net profit: revenue minus COGS, payment fees, shipping, ad spend and returns. Set product costs once (FIFO, LIFO or average) and the right cost applies automatically. See profit and margin by day, product and period. Find your most and least profitable products, add expenses, and export to CSV. Read-only and privacy-first. Know your true profit
