# ZETL CRM > ZETL CRM is an all-in-one CRM, e-invoicing, and project management software platform engineered specifically for businesses operating in Germany, Austria, and Switzerland (DACH region). It supports GoBD-compliant processes; whether a given installation is GoBD-compliant also depends on how the customer uses it. ## Product Overview ZETL CRM unifies customer relation management, automated invoicing, project milestone tracking, mobile-optimized time recording, and AI-powered document extraction into a single, cloud-native SaaS web application. There is no native iOS or Android app; every surface runs in the browser. ### Key Capabilities - **Customer Management & CRM**: Central contact directory, lead pipelines, interaction history timelines, VAT ID (USt-IdNr.) verification, and GDPR consent management. - **GoBD Finance & Invoicing**: Invoice generation with immutable archiving and audit trails, e-Invoicing support (XRechnung & ZUGFeRD 2.x standards), AI-driven invoice receipt OCR capture, EPC QR-code payment generation, and automated multi-stage dunning. - **Inventory & Purchasing**: Multi-warehouse stock management, a gapless stock journal booked automatically on delivery notes, invoices, transfers, and inventory counts, minimum-stock alerts with automated purchase proposals, purchase requests (RFQs) comparing multiple supplier quotes, and goods-receipt inspection. - **Tax Advisor Portal & DATEV Handover**: Dedicated free login for tax advisor firms with a central client overview (Mandantenübersicht), monthly pre-assigned DATEV batch downloads with linked PDF receipt images, and automatic handling of retroactive reversals (Generalumkehr). - **Projects & Time Tracking**: Multi-phase project planning, Kanban task boards, time logging in the mobile-optimized web client, and single-click handover of billable hours into GoBD invoices. - **AI Features**: AI-powered receipt capture (OCR) for incoming invoices is part of the Business tier. The conversational AI business assistant — questions about your own data, prepared analyses, drafted customer messages — is announced as a separately bookable add-on, independent of the chosen tier. It is not yet available, is not included in any tier, and is not active by default. - **Data Residency: EU as the Rule, Two Named Exceptions**: Database and Cloud Functions operate in Frankfurt (europe-west3), file storage in Belgium (europe-west1). Firebase Authentication and App Check / reCAPTCHA Enterprise are not region-bound (covered by EU SCCs and DPF). The CRM content itself does not leave the EU. Self-hosts all fonts locally without third-party CDN telemetry, and is built to support GDPR-compliant processing (DSGVO) — responsibility for the compliance of the customer's own processing stays with the customer. ## Subscription Tiers & Pricing All prices are net per user and exclude statutory VAT. The offer is addressed exclusively to businesses (Unternehmer within the meaning of § 14 BGB). - **Free**: €0, no minimum term — the contract runs for an indefinite term and either side may cancel at any time; the provider reserves the right to discontinue the Free tier, in whole or in part, with 14 days' notice (AGB § 8 Abs. 1). 1 full license, up to 3 e-invoices per month (PDF & XRechnung), customer & contact management (max. 5 customers, 4 people), quotes (max. 2 line items), guided workflows, 1 GB document storage. - **Standard**: €19/month (or €16/month billed annually, €192 per year), 1 full license included, each additional full license €7/month.
