About AccountOne
AccountOne is developing a cloud-based platform that connects online retailers and tax advisors. Our software automatically prepares data from marketplaces, online stores and payment systems for accounting. With the help of our own valuation matrix, we correctly assign sales to the appropriate tax rates and tax countries - even independently of merchandise management systems. The fully automated allocation of payment flows to revenue takes place on our platform. We then provide the data obtained as exports for the accounting department or the tax consultant. We currently support over 5,500 online retailers and more than 1,100 tax firms, who use our software on a daily basis. Our 31-strong team works in Flensburg - in a modern office with a view of the Baltic Sea.
