Purchase advice and sales

Our sales team advises on all offers and prices, processes your orders, creates invoices, delivers the software and helps with the installation of your new program. If you are not sure which licenses and services you need to work optimally, we will of course help you to find a suitable solution for your company.

The office hours of our sales team are Monday to Thursday from 9 a.m. to 4 p.m.
and Friday from 9 a.m. to 1 p.m.


How to order from us

You can order direct by email. Depending on the type and scope of the order, we will either send you a proforma invoice, which must be paid in advance, or deliver directly on account. Alternatively, there is our online shop, where you can not only order a selection of our standard products, but also choose between different payment options.

If you order an update, upgrade or maintenance, please let us know the serial number concerned so that we can process your order without delay, avoiding the otherwise necessary query.

If your company is based outside of Germany, but within the EU, please let us know your valid VAT ID, otherwise we will unfortunately have to charge you sales tax.


International sales partners

We have sales partners worldwide who sell our software, provide support and conduct training. If you are not based in Germany, take a look at the list of our sales partners to see if there is already a contact person in your country. Your advantage: you will be looked after in the respective national language. Of course you can get our products everywhere at the same prices and conditions.


Frequent inquiries


Reactivation of software

If you want to move your license to another computer, you must first release the relevant serial number on the old computer. To do this, please open the program on the old computer and carry out the following steps:

Help -> Registration -> Change registration -> Release serial number

With the released serial number you can register your software on the new computer.
Important: You can only release a license yourself once in six months.

If the release did not work or you no longer have access to the old computer (e.g. after a hard disk crash or an update of the operating system), we can release the license for you or give you permission to early deregistration. Please uninstall the software on the old computer (if still possible) and send us the "Software reactivation request" form, completed and signed, by e-mail. Processing takes about a working day.

The data collected in the form will be processed for the purpose of responding to your enquiry in accordance with legal regulations. For more details, please see our Privacy Policy.



Installation problems

If you receive any error messages when starting up the software, please send us a screenshot of the error message and the serial number via e-mail.

You should pay attention to the following points:

  • Are you using the correct version? We always provide the latest version of our software on our website; with a license for which maintenance has expired, you are only entitled to the version that was current on the last day with active maintenance. We would be happy to send you the correct link or simply use the link from our delivery.
  • Are you using the right software? Some users confuse PV*SOL and PV*SOL premium.
  • Did you enter the correct serial number? When you buy an update or upgrade, we lock your old serial number and you get a new one with your invoice. (You can find the serial number in the software under the "Help" menu item. If you no longer have access to the old installation, please use the serial number from the invoice we last issued for this license.)
