A web app on your phone that calculates true net profit per product — after 2026 platform fees, ads, shipping, returns — then helps you decide prices, promos, unit cost, when to restock, and writes the marketing. Eight tools, one account.
| Product | Price | Profit / unit | Status |
|---|---|---|---|
| Cotton Tee (Etsy) | $24.00 | $10.65 | HEALTHY |
| Ceramic Mug (Shopify) | $18.00 | $0.87 | THIN |
| Phone Case (Amazon FBA) | $12.99 | ($0.41) | LOSS |
Most sellers calculate profit as price minus cost. In 2026, a $12.99 sale also pays for:
They connect: unit cost feeds margin, margin feeds promos, products feed restock. Enter once, use every week.
Net profit per product after every cost. HEALTHY / THIN / LOSS status. A summary of which products are quietly losing money.
Minimum price for your target margin, max ad spend per order, and breakeven ROAS — the number no ad dashboard shows you.
20% sale plus offsite ads — still profitable? Get the number: "this promo only pays off if sales rise ≥ 91%".
Materials + labor + overhead + waste → true unit cost. One click sets it as COGS in the margin calculator.
When to reorder, how many units, and the cash you need — from stock, sales velocity and supplier lead time. No stockouts, no cash stuck.
6 months ahead: profit on paper vs cash in the bank. Know which month gets tight before it happens.
Etsy, Shopify plans, Amazon FBA size tiers + FBM. Kept updated. Different on your dashboard? Edit it — applies to your account only.
Captions, product descriptions, follow-up DM scripts, replies to bad reviews, 7-day content plans. Marketing without hiring a marketer.
Your ad dashboard shows ROAS. It doesn't show whether that ROAS is profitable. That depends on a number that's different for every product.
Everything left after costs and fees on the $24 tee. Spend more than this per order and the sale loses money.
Your Etsy Ads / Amazon PPC / Meta ROAS on that product must be above this. A "fine-looking" 1.5× is a loss.
Every tier gets all 8 tools. The only difference is how long. Renew any time — remaining days stack, never reset.
Data saved all year, fees auto-updated when platforms change rates, AI assistant 60/day. Launch price until Sep 19, 2026.
