Opacc
Opacc is a Swiss enterprise-software vendor headquartered in Kriens near Lucerne, focused on the Swiss and DACH Mid-Market — the broad German-speaking mid-market SMB segment. The company has built its reputation on three pillars: an integrated platform architecture, a formal update guarantee for customised installations, and its own Swiss Tier-3 data centre. The customer base concentrates on businesses with 50 to 1,000 employees in industry, wholesale, construction supply, food and beverage production and services, where the depth of customisation depth needed exceeds what most off-the-shelf SaaS offers but the buyer is unwilling to lose update-readiness as the price of that depth.
Platform and modules
The heart of the platform is Opacc OXAS, a central data-and-function layer that provides all digital company resources — data, documents, functions, interfaces, permissions — from a single foundation. On top of OXAS run the functional applications: OpaccERP for the core operational system, OpaccCRM, OpaccEnterpriseShop for e-commerce, OpaccERP MobileOffice for field force, and a structured set of integrations. OpaccERP itself covers sales and order processing, purchasing, materials management and warehousing (multi-warehouse, batch and serial), production (BOMs, routings, production orders), services and finance.
Update guarantee
A central differentiator is the formal update guarantee: even heavily customised installations can be migrated to new product versions without losing the customer-specific extensions or having to reimplement them. This is achieved through a strict separation between the standard product, the customer-specific configuration layer and the customisation code, so version upgrades touch only the standard and configuration is replayed cleanly. In a market where many Mid-Market ERPs deteriorate into "never-upgrade" legacy systems within a decade of go-live, the formal preservation of upgradability is a meaningful long-term TCO argument.
Hosting and deployment
Opacc operates its own Tier-3 data centre in Lucerne for cloud and hosting customers and offers the platform alternatively as on-premise. The architecture supports mobile operation through native clients and browser, with the OpaccERP MobileOffice extension covering field service, external sales and warehouse mobility scenarios. For Swiss customers concerned about CH data residency, the Swiss hosting is a hard differentiator versus large international cloud ERPs whose primary data centres sit in EU regions.
Target audience and verticals
Opacc's target audience is mid-market companies with 50 to 1,000 employees in industry, wholesale, construction supply, food production and services. In the Swiss market Opacc is particularly entrenched in wholesale, industry and construction supply. The product's industry-pack approach gives construction-supply customers cross-docking and multi-plant functions out of the box, food and beverage customers batch and best-before management, and industrial customers configurable production. Localisation for CH (Swiss VAT, Swiss payroll handling) is native; DATEV equivalence for DE customers (DATEV is the German cooperative of tax advisors whose data format is the SME finance standard) is supported through standard interfaces, though the home-market focus is clearly Switzerland.
Selection and competition
In the Swiss mid-market Opacc competes with Abacus Business Software, Sage 100, ProFFIX, proAlpha and abas ERP. Internationally Opacc is a Swiss specialist with a clear home-market strategy — which is a strength rather than a weakness in the Mid-Market segment where Swiss-headquartered ownership, local consulting and a Swiss data centre matter to the buying decision. Licensing is available as perpetual licence with maintenance, as subscription or as hosted/cloud from the Opacc data centre. Implementations run directly through Opacc's own consulting and engineering teams, supplemented by selected partners.

Frequently Asked Questions
What is the Opacc update guarantee?
The update guarantee is a formal commitment that customised Opacc installations can be migrated to new product versions without the customer losing their custom extensions or having to reimplement them. The architecture separates standard, configuration and customisation cleanly so upgrades remain feasible.
Where is Opacc's data centre?
Opacc operates its own Tier-3 data centre in Lucerne, Switzerland. This is the default hosting location for cloud and managed-hosting customers and is a hard differentiator for Swiss buyers with CH data-residency requirements.
Does Opacc support German DATEV?
DATEV equivalence for German customers is supported through standard interfaces, but the platform's primary localisation is Swiss. DACH customers with heavy DATEV-side dependencies should validate the specific export formats and audit posture during evaluation.
How does OpaccERP MobileOffice work?
OpaccERP MobileOffice is a mobile extension for field-service technicians, external sales staff and warehouse mobility scenarios. Service orders, customer data, stock checks and order entry can be performed on mobile devices with offline capability and synchronise to the central ERP.
