Managing accounting obligations in Switzerland requires accuracy, structure and a strong understanding of local regulations and reporting standards. As organisations grow, expand internationally or operate across cantons, internal finance teams are often under pressure to deliver timely, reliable information while remaining fully compliant.

RSM Switzerland supports Swiss SMEs and mid market organisations with outsourced accounting and financial management services that bring clarity, control and consistency. We help organisations manage their accounting obligations efficiently, allowing management teams to focus on strategic priorities while maintaining full visibility over their financial information.

Outsourced accounting and financial management

RSM Switzerland provides flexible accounting outsourcing solutions tailored to the size, complexity and maturity of your organisation. Whether you choose to outsource selected accounting activities or your entire finance function, our services are designed to adapt to your needs.

Our accounting services cover day to day bookkeeping, general ledger management, reconciliations and period end closing. We ensure that accounting data is processed accurately, consistently and in line with Swiss legal requirements, supporting reliable financial information and predictable reporting cycles.

By acting as a trusted accounting partner, we help organisations reduce administrative workload, improve process efficiency and strengthen financial governance.

Accounting and financial reporting

Financial reporting is a core component of effective financial management and decision making. RSM Switzerland supports organisations in preparing financial statements and management reporting aligned with applicable Swiss and international standards.

We assist with reporting under:

• The Swiss Code of Obligations;
• Swiss GAAP FER;
• IFRS;
• US GAAP, where required.

Our teams ensure that financial information is structured, consistent and understandable, supporting both statutory compliance and internal decision making. We help organisations maintain transparency and confidence in their numbers, even as reporting requirements become more complex.

A structured delivery model for accounting services

Our accounting services are delivered through a structured and well defined approach designed to ensure reliability and control.

Scope definition and onboarding

We begin by clearly defining the scope of services, responsibilities and timelines. This phase includes reviewing existing data, processes and controls, followed by a structured onboarding to ensure a smooth transition.

Ongoing accounting delivery

During ongoing delivery, our teams process accounting data, perform validations and ensure timely follow up. Dedicated senior contacts oversee the engagement, ensuring consistency, quality and responsiveness.

Continuous improvement

As organisations evolve, accounting needs change. We regularly review and adjust accounting solutions to reflect changes in structure, activity or reporting requirements, ensuring long term alignment.

Accounting and payroll: a financial reporting perspective

While payroll is managed through a dedicated service line, it plays a critical role from an accounting and financial reporting perspective. Personnel costs must be reflected accurately in accounting records, cost allocation structures and financial statements.

RSM Switzerland supports the integration of payroll outputs into the accounting framework, ensuring correct posting, reconciliation and reporting. This strengthens month end efficiency and improves the reliability of financial information, while maintaining clear boundaries between accounting and payroll responsibilities.

Compliance, controls and interaction with authorities

Accurate accounting relies on strong internal controls, documentation and compliance processes. RSM Switzerland supports organisations in meeting statutory accounting obligations and coordinating with relevant authorities when required.

Our teams ensure that accounting records, supporting documentation and reporting are consistent, complete and aligned with regulatory expectations. This structured approach reduces the risk of adjustments, delays or issues during audits and reviews.

Our pragmatic approach to accounting services

Our accounting services are particularly designed for Swiss SMEs and mid market organisations seeking reliable accounting execution without the need to build or maintain large in house finance teams.

RSM Switzerland applies a pragmatic, proportionate and client focused approach. We adapt our services to your organisation’s size, complexity and risk profile, avoiding unnecessary administrative layers while ensuring compliance and financial clarity.

With offices in Zurich, Geneva and Lausanne, our teams are familiar with cantonal practices and regional specificities. As part of the RSM global network, we also support organisations operating internationally, combining strong local Swiss expertise with global reach.

By combining accounting expertise, structured delivery and a deep understanding of Swiss reporting requirements, RSM Switzerland helps organisations manage their accounting efficiently, compliantly and with confidence.
