We accompany and guide you through the complicated process of corporate succession.

Here we offer you an all-round service - from the commissioning, over the preparation of the relevant documents and the search for a respectable buyer, up to the negotiation and the purchase. Here you will be supported by at least two emphatic consultants, who look after your concerns discretely.

If the company is not yet prepared for the sale, we offer support with different consulting concepts to achieve the desired purchase price.

We help you to arrange the company succession so that the handover is successful, lead the sales negotiations in your interest and support you in difficult negotiation situations as a mediator.

In tax questions and preparation of purchase contracts you will be supported by our cooperation partners who are also specialized exclusively on corporate sales.
