AOCS

What AOCS does

AOCS GmbH is a privately held Swiss consulting firm (GmbH) founded in 2003 by Andreas Otter and headquartered in Bülach, canton of Zurich, specializing in outsourcing of administrative functions for small and medium enterprises (KMU) in Switzerland. The firm delivers a five-pillar service portfolio covering accounting and controlling, HR and payroll administration, customer data and CRM management, ERP software solutions (implementation and support of Proffix, Bexio and CashCtrl), and process and change management. It does not develop or sell a proprietary software product; its core technology layer is third-party ERP platforms it resells and supports, supplemented by standard collaboration and marketing tooling (Microsoft Teams, Google Analytics, CleverReach).

The firm operates with a 3-person team consisting of the Managing Director and two functional staff (order processing/back-office and accounting). Customer segments are horizontal: Swiss SMEs lacking in-house administrative capacity, time-constrained entrepreneurs, and — as a secondary segment — European companies entering the Swiss market that need onboarding to Swiss accounting, tax and HR practice. There are no disclosed customer logos, contract values or revenue figures in the public record.

Revenue is generated through quote-based professional service engagements and ongoing service contracts; pricing is not publicly disclosed. Go-to-market is sales-led and relationship-driven, with lead generation sourced from the company website (aocs.ch), direct phone/email outreach, the Managing Director's LinkedIn profile, and SEO-driven organic search. Distribution is entirely direct (no resellers or channel partners), with in-person consultations at the Bülach office serving as the primary conversion channel.

Core offering

AOCS GmbH provides outsourcing and consulting services to small and medium-sized enterprises (KMU) in Switzerland across five practice areas: accounting and controlling, HR/payroll administration, customer data management (CRM), ERP software implementation (as partner for Proffix, Bexio, and CashCtrl), and process/change management. The company does not sell a standalone software product; instead, it delivers professional advisory, system implementation, and ongoing back-office support under bespoke service contracts.

Product overview

AOCS GmbH is a consulting and services company for small and medium enterprises (SMEs/KMU) in Switzerland. Rather than offering a unified software product, the company provides advisory and outsourcing services across five distinct practice areas: (1) Accounting and Controlling / Financial Accounting, (2) Human Resource Management (HRM) and Payroll Administration, (3) Customer Relationship Management (CRM) and Customer Data Management, (4) Software Solutions and IT — including implementation and support of ERP systems (Proffix, Bexio, CashCtrl) for SMEs, and (5) Process and Change Management. AOCS helps SMEs outsource administrative tasks in these areas to free capacity for core business activities. The company does not appear to offer a standalone software product; rather, its services are delivered through professional consulting, system implementation, and ongoing support relationships with clients.

Direct peers

• Abacus Research AG: Swiss ERP and business software vendor with implementation and partner network for SMEs — overlaps AOCS on software/ERP implementation and change management for KMU.
• BDO AG (Switzerland): Largest Swiss mid-tier accounting and advisory network with deep outsourcing/Treuhand services to KMU across accounting, HR, payroll and ERP-related processes — directly comparable service mix to AOCS, but at much larger scale.
• Helbling AG: Swiss IT and management consulting firm serving mid-sized industrial and service clients across ERP implementation, process optimization and digital transformation — comparable advisory/IT-outsourcing footprint to AOCS.

Broad incumbents

• KPMG AG (Switzerland): Big 4 firm with a sizeable Swiss SME/mid-market practice covering accounting outsourcing, HR, tax compliance and process advisory — much broader capability set but competing for the same KMU buyer.
• Mazars AG (Switzerland): International mid-tier audit and advisory firm with Swiss operations serving SMEs with accounting, payroll, tax and process outsourcing — broader footprint than AOCS in the same buyer segment.
• PricewaterhouseCoopers AG (Switzerland): Big 4 firm with established Swiss SME/mid-market practice delivering outsourced finance, HR and transformation services — competes for the same KMU outsourcing budgets at premium scale.
• Crowe AG (Switzerland): Mid-tier international accounting and consulting network with substantial Swiss practice, delivering outsourced accounting, tax, HR and advisory services to SMEs — broader portfolio than AOCS but overlapping SME BPO.
• Ernst & Young AG (Switzerland): Big 4 firm active in Swiss mid-market with outsourced finance, HR and consulting services — relevant incumbent competing for the same Zurich-region KMU clients as AOCS.

Others

• Bexio AG: Swiss cloud accounting/ERP vendor and direct AOCS technology partner — also adjacent competitor because its self-service platform can displace the implementation services AOCS resells.
• Proffix AG: Swiss ERP software vendor for SMEs and AOCS's core implementation partner — adjacent ecosystem player whose direct onboarding/service could substitute for AOCS's consulting layer.
