A unified commerce platform is only as powerful as the understanding behind it. This glossary brings together the key concepts, capabilities, and architectural principles that define modern retail technology, from order management and inventory optimisation to fiscal compliance and the emerging world of agentic commerce. Whether you are evaluating your current technology stack, planning an international expansion, or building the case for change internally, these definitions provide the shared language that makes those conversations sharper and faster.
GK Software leads the market in POS volume, with 570,000+ installations across 65 countries, built primarily for grocery and convenience retail. EVA is purpose-built for fashion and luxury, with a native iOS platform, unified clienteling, and a 14-week implementation that includes POS, OMS, Inventory, Loyalty, and Clienteling out of the box.
Introduction
GK Software operates at impressive scale, recognised as the global #1 in new POS installations by IHL Group. But dominance in grocery does not translate to excellence in fashion. GK's cross-platform, enterprise-complexity model requires deep customisation for fashion workflows. Its April 2025 divestiture of Deutsche Fiskal creates uncertainty in the fiscal compliance layer. And for mid-to-large fashion and luxury brands, GK's implementation model means months of professional services before a single sale is rung. EVA delivers everything GK promises, and the fashion DNA GK doesn't have.

Five key reasons to choose EVA
1.
Fashion-first DNA
Every feature (size/colour matrices, VIP clienteling, luxury UX) is designed for how fashion associates sell.
2.
Apple Enterprise Labs co-designed UX
EVA's interface is developed in partnership with Apple Enterprise Labs, making it the most intuitive POS in the market. New and part-time associates transact confidently from day one. No formal training required.
3.
One Unified Shopping Basket
No synchronisation jobs, no channel silos. One real-time basket shared across POS, mPOS, consumer app, website, and social commerce. GK's modular architecture cannot deliver this.
4.
Headless core vs. platform modules
EVA's commerce engine continuously renews itself from the inside out. GK's CLOUD4RETAIL is a services package . Adding capabilities means adding modules and complexity, not evolving a core
5.
Fiscal Confidence
With GK divesting Deutsche Fiskal, EVA's native 40+ country compliance is a decisive advantage for global fashion retailers.
Frequently Asked Questions
FAQ
Is EVA better than GK Software for fashion retail?
Yes. GK Software is the world's largest POS installer by volume, but its focus is grocery and convenience retail. EVA is purpose-built for fashion and luxury, with native iOS performance, luxury clienteling, and unified commerce out of the
box. Fashion retailers consistently report faster go-live times, better associate UX, and more complete omnichannel capabilities with EVA.
Does GK Software have good fiscal compliance?
GK Software had strong fiscal capabilities through Deutsche Fiskal, but divested that business in April 2025. EVA maintains native fiscalisation in 40+ countries as a core platform feature, not a third-party add-on, giving global
fashion retailers a stable compliance foundation.
What is the difference between GK OmniPOS and EVA?
GK OmniPOS is a modular enterprise services package requiring separate components for mobile POS, inventory
management, and loyalty. EVA delivers POS, OMS, Inventory, Loyalty, and Clienteling in a single native iOS platform,
eliminating integration complexity and reducing total cost of ownership.
Can EVA replace GK Software in existing retail operations?
Yes. EVA has successfully replaced legacy and enterprise-class POS platforms across European and global fashion
retailers. The standard 14-week implementation programme includes data migration, staff training, and go-live support
with a dedicated fashion retail team.
Final Verdict
GK Software commands impressive market share in grocery and large-scale enterprise retail. But for fashion and luxury brands demanding iOS-native performance, luxury-grade clienteling, built-in fiscal compliance, and a partner with deep fashion DNA, EVA is the superior choice. As GK restructures around its core grocery business, EVA's focused vision for contextual, connected fashion commerce positions it as the clear alternative for the world's most demanding fashion retailers.
