Steuerberater Sonnemann & Partner

For comapnies

We provide you with comprehensive support

by delivering individual services for companies and organisations. We will assist you all the way from the start-up phase of entrepreneurial activity to succession planning. The goal is always to expand and foster long-term success. We will be happy to make you an offer.


We can take care of your financial accounting needs either digitally or in analogue form. DATEV software modules allow invoices and receipts and appraisals to be matched digitally. We can also take a traditional paper-based approach if you prefer.

Our office management services can help you with any administrative tasks that occur within the accounting environment. We will come to your premises and scan your vouchers and documents for you. We will also file the originals.

We will be happy to enhance your bookkeeping procedures by performing a highly informative cost accounting analysis.

If you wish your financial accounting to remain in-house, we will support you and your staff in optimising processes and will provide guidance on all aspects relating to accounting.

Annual financial statements

Annual financial statements act as a calling card for your company and also present an opportunity to present yourself in a positive light to business partners and banks. We are an expert port of call for all matters relating to financial accounting law pursuant to HGB and IFRS/IAS.

As well as enhancing your image externally, annual financial statements also offer you effective evaluations which will support you with forward-looking governance.

We also prepare annual financial statements for companies whose accounting we do not handle as long as you are able to ensure that the evaluations you submit meet a minimum quality standard.

This means that the audit is conducted efficiently and at a reduced cost.

Statutory audits

Corporations which German Commercial Code defines as being medium-sized or large are subject to a statutory obligation to have their annual financial statements and management report externally audited.

An audit report which meets current requirements will inform your business partners (customers, suppliers, banks etc.) of the correctness of your financial reporting.

When we conduct an audit, we look at your business processes in detail and identify critical areas. This allows us to provide you with practical indications of the strengths and weaknesses in your company. We then explore all the relevant points of the audit with you in a detailed final discussion. Our services further include a professional presentation of the audit report to the supervisory bodies responsible.

Voluntary audits

Even if there is no statutory obligation, an audit of your annual financial statements may be necessary due to contractual agreements entered into (e.g. credit or investment agreements) or indeed by dint of other requirements. You should view such an audit as an opportunity to portray yourself in a positive light, including with regard to your company rating.
