de_core - 2026 Pricing, Features, Reviews & Alternatives

de_core is e-commerce business intelligence and profit analytics for small and mid-sized online retailers in Germany, Austria and Switzerland, built as a digital twin of the business instead of a

dashboard.

What it reads, read-only, through API keys: shop systems (Shopify, WooCommerce, Shopware), ERP and inventory systems (xentral, VARIO, Billbee, weclapp), ad accounts (Google Ads, Meta), payment providers (PayPal, Stripe), shipping (Sendcloud) and marketplaces via the ERP or order hub. More than 75 integrations. Connected in minutes, first findings within the hour.

What it computes. Contribution margin per product (DB1 to DB3) from the purchase price on the ERP document minus shipping, payment and marketplace fees, expected return cost per product and the ad-spend share per order. Break-even ROAS and POAS per campaign from VAT, margin and return rate of the advertised products, with budget allocation across channels solved as a constrained optimization (Lagrange/KKT). A 13-week cash-flow forecast with payout delays per payment provider, return backflow and supplier due dates. Reorder points and quantities with an (s,Q) policy and safety stock from demand and lead-time variance, plus slow movers and shelf-life handling. Customer value with BG/NBD and Gamma-Gamma, churn risk per customer with LightGBM and SHAP, the optimal timing and discount of a win-back email (Pontryagin). Demand forecasts with Holt-Winters, Kalman and TSB, with conformal intervals.

How it thinks. A causal model with six dimensions (inventory, customers, brand, marketing, finance, operations) and eleven time-lagged effect paths: an order today, the ad effect after seven days,

the payout after fourteen, the return after three weeks. On this model de_core runs forward simulations over 7, 14 and 30 days with 500 Monte Carlo paths and translates every action into euros. Every night the whole business is recomputed.

How it speaks. 27 alert rules run hourly, each with the euro amount at stake: reorder deadline in three days, product sold below cost, return outlier per product pointing to a batch or packaging issue, shipment without scan for 48 hours, service topic spike, subscription payment failures, payment fee deviating from the provider contract, liquidity below zero within 13 weeks. Every morning at

07:15 a digest lists the prioritized actions with euro amount, confidence and horizon. An analyst agent reads 37 measurement tools, researches externally when needed and drafts reorders, budget shifts, discount decisions and retention emails. Nothing is executed without the merchant's approval; outbound the system only sends emails.

How it learns. Two loops: one measures what an approved action actually delivered and prefers action types with proven effect; the other grades every forecast (Brier score) and recalibrates causal

weights and alert thresholds weekly. After three months the model is the merchant's own.

What it is not: no price radar or repricer, no marketplace listing or ad management, no replacement for shop, ERP or accounting, no tracking pixel, no app store app.
