Collmex — Cloud Accounting and ERP for Very Small Businesses

Collmex is one of the longest-tenured cloud-based commercial-software products in Germany, developed by Collmex GmbH in Saarbrücken since 2003. The company positions itself as a pioneer of the software-as-a-service model in the German-speaking market and reports more than 10,000 customers, ranging from self-employed individuals to smaller Mid-Market (mid-market) operations. At the centre stand browser-based tools for invoicing, financial accounting, merchandise management, project billing and association management. Rather than offering a monolithic ERP system, Collmex provides modular packages that scale from free invoicing freeware to the complete Collmex pro solution with assortment, warehouse and accounting functions. Hosting and data storage are in a German data centre certified by the eco association with five stars. Collmex therefore positions itself as a pragmatic vendor for small businesses, self-employed individuals and associations seeking a lean, browser-based solution with GoBD-compliant bookkeeping (the German principles for proper digital bookkeeping), without entering complex ERP projects.

Overview

Collmex operates in a distinctive position in the DACH cloud-software market — one of the earliest German SaaS products, with two decades of operational tenure and 10,000+ customers concentrated in the very-small-business segment. The product strategy emphasises pragmatism over functional breadth: rather than competing with weclapp or Xentral at the upper SMB end, Collmex targets the segment below cloud-native ERPs — freelancers, self-employed professionals, small craft businesses, consultancies, associations and the smallest Mid-Market operations with 1 to 10 users. Trade media such as Cloudcomputing-Insider and Heise regularly cover new features, particularly mobile-device optimisation and the incremental extension into e-invoicing (ZUGFeRD, XRechnung) and electronic document capture. The Tier 3 niche-specialist positioning on erp-software.org accurately reflects the focused product strategy.

Functional sweet spot

Collmex covers the full spectrum of commercial tasks for small businesses. The accounting module supports quotes, orders, invoices, credit notes and dunning, with integrated open-item management. Financial accounting includes SKR03 and SKR04 chart of accounts (the German standard charts), VAT pre-registration via ELSTER, balance sheet and profit-and-loss statements, travel-expense accounting and asset accounting. The complete Collmex pro package adds merchandise management with warehouse, ordering and stock-take, a simple CRM, project time tracking and a connector to online shops. A DATEV interface (the German accounting and payroll standard) enables standardised exchange with tax advisors. For associations a dedicated package handles member management, contribution invoicing and SEPA direct debit. Collmex supports electronic invoicing in ZUGFeRD and XRechnung formats, making it suitable for B2G commerce. Pre-built shop connections to Shopify and WooCommerce serve the e-commerce-light use case typical for the customer base.

DACH positioning

Collmex is exclusively German-anchored with strong concentration in Germany and modest presence in Austria. The localisation is comprehensive: SKR03 and SKR04 chart of accounts, ELSTER integration for VAT pre-registration, native DATEV connectivity for tax-advisor handover, GoBD compliance and ZUGFeRD plus XRechnung e-invoicing. Hosting is exclusively in a German data centre with eco-association five-star certification. The customer profile is consistent: freelancers, self-employed consultants, small craft businesses, small consultancies, associations (Vereine) and small Mid-Market operations with 1 to 10 users. The product's explicit positioning at the bottom of the size spectrum means it competes with sevDesk, Lexware Office and FastBill rather than with weclapp or Xentral. The two-decade tenure has built a deeply loyal customer base.

Pricing and implementation

Collmex pricing is transparent and published per package. Indicative ranges: free for the basic invoicing freeware (single user, limited transactions), 12 to 19 euro per month for the Collmex accounting package (small-business bookkeeping), 19 to 39 euro per month for Collmex Rechnung (invoicing and accounting), 49 to 99 euro per month for Collmex pro (full accounting plus merchandise management plus warehouse) and 9 to 19 euro per month for the dedicated association package. Implementation is essentially self-service: a single user can sign up online and be productively invoicing within hours. The free first-month trial is standard. Total cost of ownership over five years for a typical 3-user small-business deployment sits in the 2,000 to 6,000 euro range — among the lowest in the DACH cloud-software category.

Selection considerations

Collmex is a strong fit for very small German businesses, self-employed professionals, small craft businesses, small consultancies and associations with 1 to 10 users that want a transparent, GoBD-compliant cloud solution at predictable monthly subscription cost. It is particularly compelling for buyers who explicitly value Collmex's 20-year operational tenure and the strict German hosting and data-residency, for associations needing dedicated member-management features, and for very small businesses that have outgrown manual or spreadsheet-based accounting. It is less compelling for organisations above 10 users (where weclapp, Xentral or Haufe X360 deliver more functional headroom), for businesses with complex multi-channel commerce or manufacturing requirements, or for international operations needing multi-currency consolidation and non-German accounting handling.
