In detail
In focus.
Everything runs from day 1. Here are three in detail.
Amazon shows revenue. Faktor400 shows what's left.
15+ cost components — Amazon fees, COGS, PPC, shipping, returns, customs, overhead — across four levels: per order, per product, per day, per month. Real-time alert when a product goes unprofitable.
- Real contribution margin instead of revenue illusion
- Spot unprofitable products before they eat your margin
- Automatic, not manual — no more spreadsheet gymnastics
15+ cost components. At order level. With alerts.
See it in the demo →No global target ACOS. Faktor400 knows each product's margin.
Dynamic target ACOS per product, calculated from real margin. 6 recommendation types — raise bid, lower bid, pause, adjust budget, add keyword, set negative keyword. Every recommendation with a confidence score (0–100). Statistical safeguard: minimum 10 clicks before any action is recommended.
- PPC decisions per product instead of a blanket target ACOS
- Confidence score shows which recommendations you can trust
- Included in every Faktor400 plan — no extra charge
PPC recommendations in every plan. No extra charge.
See it in the demo →Do you already know where the month will end?
Faktor400 knows the difference between Monday and Sunday. Weekday-weighted seasonality, trend detection with exponential weighting, a 95% confidence interval that narrows each day. For new accounts: a graceful fallback to an average forecast that improves as data grows.
- Month-end forecast for revenue, profit, and units — from day 1
- Confidence band that shows you how certain the forecast is
- Weekday-weighted. Self-calibrating. From day 1.
Weekday-weighted monthly forecasts.
