A control room for Etsy · Shopify · Amazon sellers
Your business control room, on your phone: true net profit per product after 2026 fees, ads, shipping and returns, then prices, promos, unit cost, restock timing and the marketing. Nine tools, one account. You build the store, the numbers keep watch.
Nothing to install. Email-code login. Your data saved to your account.
The problem
Most sellers calculate profit as price minus cost. In 2026, a $12.99 sale also pays for:
Figures from the Margin Calculator with 2026 fees. This one is the best seller.
Per unit, before the 15% referral fee and before your ads. On a $12.99 item that is 27% of the price gone before you count a single cost of your own.
Build tools
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 / VERY THIN / LOSS status, plus 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, not a feeling.
Materials, labor, overhead and waste become the 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.
Six 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 and FBM. 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.
Google Trends inside the app: keyword demand over time, the map of where it's searched most, rising related searches, Amazon vs Etsy vs eBay comparison, today's trending searches and keyword ideas people actually type.
If you run ads
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 or Meta ROAS on that product must be above this. A fine-looking 1.5× is a loss.
Pricing
The only difference is how long. Renew any time, remaining days stack, never reset.
