Darum Brasser Accounting Solutions Bookkeeping
Founded out of a passion for accounting
What began as a sole proprietorship by Mandy Brasser (then still under the name Mandy Jacob) was more than the start of classic bookkeeping. It was the beginning of a vision: to make bookkeeping digital, understandable, and service-oriented. With expertise, commitment, and an eye for detail, a modern approach was developed, which forms the basis of our success today.
Grown from experience – reimagined 2025
In 2025, the original company became a joint venture with new partners: the Swedish Tax Office and our partner company, Quint GmbH. This merger combines international experience, technological expertise, and personal advice – for comprehensive, digital accounting solutions of the highest standard.
Digitally organised, personally supported
We combine modern software solutions with direct communication. Each client has dedicated points of contact who handle issues quickly and individually. This way, we create the perfect balance between efficiency and humanity – accounting that works and is understood.
Reliability, Quality & Trust
Our work stands for precision, data security, and the highest level of care. Whether payroll, financial, or construction payroll accounting – we guarantee structured processes, punctual results, and transparent communication. Because trust is built on reliability – and that's precisely our claim.
Excellent quality & strong partnerships
