abacusNews: Price Collapse! 

Subscriptions become cheaper!

As of January 01st 2018, abacus subscriptions become cheaper again. Please ask for details!

Furthermore, it becomes much easier to acquire the exact and needed number of licences for the installation version abacus4b. Use packages of five, ten, 25, 50, or 100 licences. Even individual licences for installation are now available. But, of course, our economic "Flat" for an arbitrary number of users continues to be available.

Finally, in our online version abacus4u,for the "shared" licences we are removing the restriction that all users have to be in the same organisation. Freely distribute your single licences now internally or to your external clients. And should you consider "One-for-Ten" too thin, use the new "One-for-Three" or "One-for-Five".

... and, as it will be Christmas soon:
For every order placed until the end of this year, December 2017 will be included free of charge!

... and, as it really will be Christmas soon:
If your order reaches us exactly on December 24th 2017(e-mail, fax, phone; normal mail on 23d 2017),
we will give you the whole first quarter of 2018 as an additional present on top:
the first half year's invoice 2018 will be halved!
