Please note: Offers for maintenance renewals of an existing license can be found in the appropriate customer account at "Downloads/Updates".

Yes, there is a reinstatement fee for lapsed maintenance on top of the maintenance price:

If the maintenance has expired more than 3 months, the fee will be 20% of the current license price. For an interruption of more than 1 year the fee will be 40%.

The regular price for a maintenance renewal is about 50% of the license price for a 12 months renewal, multi-year renewals are more cost efficient with up to 47% per year for 36 months maintenance.

For outdated maintenance, an additional reinstatement fee might apply. However, the renewal price is always still lower than purchasing a new license.

A single license basically allows one installation and user which may change every 30 days according to our license agreement.

A site license covers all installations and users of one entity within one city.

For our software TreeSize Professional, we can offer countrywide or worldwide company licenses which cover an unlimited number of installations and users of one entity, either countrywide or global.

These licenses are individually calculated based on the number of employees and a possible usage quota, but the calculation starts at more than 10,000 assumed installations/users. A smaller volume can be licensed with single licenses for which we have a price scale on our price list.

VISA, MasterCard and American Express implemented the new Payment Security Directive (PSD2). The new security requirements are mandatory to provide the utmost safety for the payments of our customers and prevent credit card fraud. But the automated request is solely initialized by the card-issuing institute (your bank).

So, if you encounter these errors during the payment or you do not know how to retrieve your code for the authentication of the payment, please contact your bank. Unfortunately but for good reasons we have no influence on that.

A Consultant License, which we currently offer for our software TreeSize Professional, is a so-called Named User License. The license is assigned to one person in the licensee's company. This has the surplus value for the named user that he may install the software one after the other on any number of machines in your own company or at different customers, for the period of use. This makes license management less complex.

Especially IT-Admins or technicians who work on a variety of different systems can benefit from this licensing option.

You may find further information about the licensing in our license agreement at:


To get technical support for our product your maintenance period must be valid. Customers that are covered by maintenance are able to download all updates for free.  If there is a support case, we will typically ask our customers to install the latest version, as this may already fix the issue. If the latest version cannot be used for comprehensible reasons, we will also provide support for previous versions, but those will not receive any more updates.


You can look up the end of your support period in our customer area. There you can also renew it for a reduced price and will then get technical support and updates again.
