RoasLens is a Polish e-commerce profitability analytics tool. It connects Allegro, Meta Ads, Google Ads, BaseLinker, Google Analytics 4 and Fakturownia in one panel and shows real net profit in PLN — today, not at month-end — after product cost, marketplace commissions, shipping, ad spend and tax.
Every ad and sales panel shows only its own slice, so the one number that matters — how much you actually keep — is hidden. RoasLens joins these sources and calculates net profit, ROAS and profit-on-ad-spend automatically and daily, plus plain recommendations (what to scale, trim or turn off), a bookkeeping/tax module (net income, PIT, foreign invoices at the Polish NBP rate, AI reading of PDF amounts) and a demand calendar.
Built for Polish e-commerce sellers by a seller, not a software house — created by Sebastian Pietrzak (P.P.H.U. DEOZE) out of the need to know his own shop's real profit. Read-only access, encrypted API keys (AES-256-GCM), two-factor login, one-click disconnect.
