YetiForce
YetiForce is an open-source CRM and ERP system from the Polish vendor YetiForce S.A., headquartered in Warsaw. The software has its roots in a fork of Vtiger CRM but has been significantly modernised and extended over the past years with numerous ERP-adjacent functions. YetiForce positions itself today as a multi-dimensional platform that covers not only the classical CRM tasks (contact, lead and opportunity management) but also sales, marketing, projects, support, HR, accounting and inventory under one roof. According to the vendor, the system is used by around 23,000 companies in more than 100 countries; the largest known installation runs more than 35,000 active users. YetiForce is primarily deployed on-premises — the open-source nature gives customers full control over data and infrastructure, which is the core argument for the buyers who choose YetiForce over commercial cloud alternatives.
Platform overview
YetiForce is delivered as an open-source self-hosted application with full source-code access. Functional scope covers contact and account management, sales pipeline and opportunity management, lead capture and lead-scoring, marketing campaign management, customer-service ticketing with SLA tracking, project management and time tracking, basic HR with employee records and leave management, basic accounting and invoicing, inventory and warehouse, and integration with the standard SMB application stack through APIs. The underlying technology is PHP and standard relational databases, which makes the product easy to host on commodity infrastructure. The vendor offers commercial support packages and hosted-environment services alongside the free open-source distribution.
Functional sweet spot
The functional sweet spot is technically capable SMBs and Mittelständler between roughly 10 and 200 users who want a full-featured CRM-and-ERP platform with no per-user licensing cost and full data sovereignty. Typical customers include technology-driven SMBs, organisations with strong data-sovereignty requirements (regulated industries, public sector, defence), and businesses in countries where the localisation of major proprietary platforms is weak. The integrated CRM-marketing-projects-HR-accounting scope is broader than typical pure-CRM open-source competitors. YetiForce is not designed for organisations that want a low-touch commercial SaaS experience — for that use case, HubSpot, Salesforce or commercial cloud CRMs are typically better fits.
DACH positioning
YetiForce's DACH localisation covers German-language user interface and the standard European compliance baseline (GDPR-aware personal-data handling, European VAT). GoBD compliance (the German principles for proper digital bookkeeping) is not a native product certification — achievability depends on the specific deployment configuration, the audit-trail discipline of the customer, and the customer's auditor sign-off. DATEV (the dominant German payroll and accounting standard used by most tax advisors) integration is handled through community modules and customer-specific connectors rather than as a vendor-certified feature. The DACH partner channel for YetiForce is smaller than for the established commercial CRM and ERP products in the region. The relevant scenario for DACH buyers is technically capable SMBs with internal IT who value full source-code access and full data sovereignty over vendor-certified DACH compliance.
Pricing and implementation
The open-source distribution has zero licence cost. Commercial support packages from the vendor are available with tiered SLA depth. Total cost of ownership comes from infrastructure (hosting, database, OS), implementation services and ongoing maintenance. For a 50-user YetiForce deployment, all-in TCO over five years typically lands in the 80,000 to 250,000 euro range, dominated by implementation and operational effort rather than software licensing. Implementation cycles run 3 to 9 months depending on scope and the depth of customisation. The pricing model is materially lower per user than Salesforce or Microsoft Dynamics 365 Sales, which is the core commercial argument for choosing open-source.
Selection considerations
YetiForce is a defensible choice for technically capable DACH SMB and Mid-Market organisations between 10 and 200 users who want a full-featured open-source CRM-and-ERP platform with full data sovereignty and no per-user licensing cost. It is less compelling for organisations that prefer a commercial SaaS experience (HubSpot, Salesforce, Microsoft Dynamics 365 Sales fit better), for buyers requiring vendor-certified GoBD or DATEV depth out of the box, for businesses without internal IT to maintain an open-source platform, or for organisations needing deep industry-specific functionality where dedicated industry products outperform the generic open-source scope. Buyers should evaluate the size of the local YetiForce implementation partner network and the depth of community module coverage for DACH compliance as part of due diligence.

Is YetiForce actually free?
Yes. The open-source distribution has zero licence cost and full source-code access. Commercial support packages from the vendor are available alongside the free distribution for customers who want SLA-backed support.
Where is YetiForce headquartered?
Warsaw, Poland. The product has its roots in a fork of Vtiger CRM but has been substantially modernised and extended into a broader CRM-and-ERP platform over the past years.
How many companies use YetiForce?
According to the vendor, around 23,000 companies in more than 100 countries use YetiForce. The largest known installation runs more than 35,000 active users.
Does YetiForce support DATEV and GoBD?
Native vendor-certified DATEV and GoBD support is not part of the product. Achievability for DACH compliance depends on the specific deployment configuration, the audit-trail discipline of the customer and the customer's auditor sign-off. For risk-sensitive DACH deployments, commercial DACH ERPs with certified DATEV and GoBD are typically the safer choice.
