Self-employed, company development, depreciation?

I started my own business a month ago and am currently building my own company as an insurance agent. My tasks are staff implementation, coaching, planning, & the most important thing to help humanity in life.
Since I'm still a newbie, I don't know certain things such as copying.

My question would be,

At work I need certain things, such as a laptop or an Ipad for planning, coaching, etc.

or if I had to drive to the customer.

Can I copy this off?

Would I get paid for part of it?
if yes what percentage?

It's now that I need it 100% in the company, I've heard from a few people in my area that you get paid up to 80% for that. Before I get information from the BH, I wanted to hear something from you if one or the other has experience with it.
I would also be happy if one or the other is familiar with the topic of what I can do as a self-employed person in a positive way.

Consultation with the competent Chamber of Industry and Commerce regarding business start-ups is urgently required

Purely operational expenses can in principle be recognized as tax-effective. This means that the taxable income is reduced by the amount. I strongly recommend that you consult a tax advisor and transfer the accounting to a tax advisor right from the start. The German tax office is not to be trifled with.

It is of course possible that expenses will also be covered by contractual partners. But that has nothing to do with depreciation or tax. That should also be clarified.

In addition, I recommend familiarizing yourself with the basics of founding and the basics of business administration. There are courses or management consultants like me who can teach these basics.

Thank you for your answer, I'm from Austria.

started doing this recently. The courses are paid for by the company. The first course starts at the weekend.

But wanted to inform me a bit beforehand.

The principle is the same in Austria. However, the tax office in Austria is a pure fun club compared to the one in Germany.
