Accountone – The All-In-One Solution for Online Sellers and Tax Consultants

AccountOne offers an online interface, which takes sales data from Amazon, Ebay, individual webstores and other online selling platforms and prepares it for the tax consultant. Our unique evaluation matrix assigns sales their correct tax rates and tax countries independently of a merchandise management system. The extracted data can then be sent as automated invoices to the customer as well as made available to your accounting department or tax consultant.

In addition, delivery thresholds are actively monitored and potential excesses are preemptively pointed out. In the case that a threshold is exceeded, AcountOne will automatically adjust the valuation of the sales. This ensures that invoices are always accurate and sales data for the tax consultant flawless.


Once set up, AccountOne operates seamlessly without the need for manual uploads or constant follow up


The collected data is assessed and then prepared for VAT and accounting purposes


Invoices are prepared from the collected data and automatically sent to the customer.

Delivery Thresholds

Delivery thresholds are actively monitored, also in the PAN-EU network, protecting you from potential violations


With just one click, the tax consultant receives perfect data for accounting and tax purposes – field tested and proven!

At the end of each month, accounting data as well as the complex data for the VAT Returns are made. Whereas in Germany the import of accounting data suffices, AccountOne also prepares the data for VAT purposes in all EU countries. In this way tax declarations can be made in other EU countries.

In addition, we offer a complete and competent VAT compliance service through our own network of European tax advisors.

Tax Consultants

As a tax consultant you face great challenges in serving online retailers. Monitoring delivery thresholds, short-term determination of all sales, including VAT and accounting assessments, are just a couple of your daily areas of focus. Especially through Amazon’s Pan EU program, goods are shipped across Europe in the form of intra-community transfers. Within no time various distance selling thresholds are exceeded and the sheer amount of data seems to increase immensely. With AccountOne and just a few clicks you are able to monitor all movements and transform them into perfect accounting data.  The data is then easily exported into your bookkeeping system, or as DATEV or CSV Format.

Hours or work putting together data from the different sales channels are a thing of the past.

In addition, you can offer your clients our software which creates and sends automated invoices directly per email to customers from the different sales channels.
