In detail

In focus.

Everything runs from day 1. Here are three in detail.

Amazon shows revenue. Faktor400 shows what's left.

Amazon fees, cost of goods, advertising and returns — per product, per day and per month.

  • Real contribution margin instead of revenue illusion
  • Spot unprofitable products before they eat your margin
  • Automatic, not manual — no more spreadsheet gymnastics

Fees, cost of goods, ads, returns. Per product.

No global target ACOS. Faktor400 knows each product's margin.

Dynamic target ACOS per product, calculated from real margin. Recommendations on bids, budgets and keywords, each with a confidence level. Statistical safeguard: minimum 10 clicks before any action is recommended.

  • PPC decisions per product instead of a blanket target ACOS
  • Confidence level shows which recommendations you can trust
  • Included in every Faktor400 plan — no extra charge

PPC recommendations in every plan. No extra charge.

Do you already know where the month will end?

Faktor400 knows the difference between Monday and Sunday. Weekday-weighted seasonality and trend detection with exponential weighting. For new accounts: a fallback to an average forecast until enough data is available.

  • Month-end forecast for revenue, profit, and units — from day 1
  • New accounts: an average forecast until enough data is available
  • Weekday-weighted. Trend-aware. From day 1.

Weekday-weighted monthly forecasts.
