weclapp is a German cloud ERP + CRM platform operated by weclapp SE, a Societas Europaea legal form adopted to support international expansion, with offices in Frankfurt am Main, Marburg, Kitzingen, and Karlsruhe. Founded in 2008, the platform combines CRM, sales pipelines, quotations, invoicing, accounting, project management, and full inventory/warehouse management for SMBs and mid-market companies, with strong integrations into German marketplaces, payment providers, and shipping platforms (Amazon, eBay, Shopify, etc.). The product has won "ERP-System des Jahres" multiple times and is positioned as the first German cloud ERP with TÜV-certified data protection.
For procurement-grade EU buyers the hosting story is among the strongest in this directory. Customer ERP/CRM data is stored exclusively on a Frankfurt am Main data centre with a Karlsruhe backup; both facilities carry an exceptional certification stack (ISO 9001, ISO 27001, ISO 27018, ISO 27701, ISO 22301, ISO 20000-1, PCI-DSS, CSA STAR CCM v4.0, SSAE16 / ISAE3402). No US-owned hyperscaler sits in the customer-data path. The privacy policy (last updated September 2024) names sub-processors transparently; the US-resident ones (Google, Microsoft, Intercom, Productboard, Meta, LinkedIn) are scoped to marketing-site analytics, advertising pixels, customer chat, and product roadmapping rather than customer business records, with SCCs cited under Art. 46 GDPR for any onward transfers. Brevo (FR) handles newsletters and Personio (DE) handles application data.
Pricing in EUR: ERP Starter €39/user/month, ERP Services €86/user/month, ERP Trade €163/user/month, Enterprise custom for 10+ licences. A 30-day free trial requires no credit card and auto-cancels. Best fit: German and DACH SMBs and mid-market companies that need an integrated ERP + CRM with explicit German data residency, multi-ISO certifications, and broad e-commerce-marketplace integrations. The lack of an obvious public DPA URL is the primary friction for a fully procurement-grade buyer: request the AVV directly and confirm the Frankfurt / Karlsruhe DC contractual commitments before signing.
