How can we help you?
The hsp support team will be happy to help you
Whether you’re experiencing technical issues, have a query or any other concern – please get in touch. Our highly qualified support team will listen to your concerns and help you as quickly as possible. We’re usually available on weekdays from 8 am to 5 pm, and we’ll get back to you as soon as possible outside of office hours.
Please note that we charge for technical assistance that falls outside the scope of our software support. Should a service incur a charge, we will, of course, clearly inform you of this in advance.
Comprehensive training courses available
Are you looking to expand your own knowledge or that of your team, rather than tackling a specific problem? If so, we recommend our informative and insightful training courses. Book a session today – we look forward to seeing you.
The best way to sort out a problem straight away is a face-to-face conversation. You can reach our helpline on +49 40 53 43 69 199.

Innovation made in Germany
Why so many professionals put their trust in hsp

Excellent support
A software solution is only as good as the support that comes with it, particularly when it comes to specialist software. That is why we offer you:
Community Help
With your Opti.Tax licence, you gain access to the hsp Community. There, you’ll find a host of exclusive benefits:

Expertise included
On many issues, we rely on practical expertise and work closely with partner law firms.
Excellent support
Software and support go hand in hand
Our aim is to provide you with the best professional tools available. This encompasses not only the features and innovations within the software, but also, and in particular, outstanding support. After all, the quality of a partnership is not determined when everything is running smoothly, but in times of challenge.
When you choose hsp and the Opti.Tax software platform, you’re getting more than just a tool. We view our relationship with you as a partnership designed to benefit both parties. That’s why we’re here for you – out of a genuine commitment.
When it comes to support, too, we rely on ‘Made in Germany’
We are a medium-sized company based in Hamburg. Our products are far more than just standard tools that simply have to work. That is why we cannot outsource our support without compromising on technical quality. So we don’t.
The entire hsp support team is based in Hamburg, in the same premises as the software developers. This means you can rest assured that our support staff have in-depth knowledge of all our products, are fully up to date, and can pass your feedback directly on to the development team.
