In Sweden you can sell your company to a specialized company that will dissolve it for you (for example this one: https://www.standardbolag.com/services/liquidation). This can be done in a matter of 1-2 weeks.
In Sweden, you can of course also choose to dissolve it yourself, but nobody does that since it takes years, and it's pretty cheap to let someone else take care of it for you.
It sounds like the same service is not available on the market in Germany?
afaik there is no formalized process to sell for winding down a company in germany as in sweden, though some attorneys offer a service to connect with some clients that want to start a company and try to do a swap, which is legally a grey area. I did that also once but it was a nightmare in a differnt way and took not much less time and energy. I am sure you can be lucky there if the timing is right and the people taking over are not complete idiots but it took still 1.6 years until everything was completely over. Only (maybe) worth it if the people taking over are totally vetted and the company they want to run is similar enough to the old one so the trigger for "wirtschaftlichen Neugründung" does not take action, otherwise they have to basically do the same as founding a company from scratch and it makes no sense financially.
In Sweden you can sell your company either to used as a "shelf company", meaning the buyer will later resell it, or you can sell it with the promise that it will be dissolved/liquidated and not resold.
It seems much more popular to sell it to be dissolved since there are some risks involved with someone else using it in the future.
So I can understand if it is not very popular in Germany either to sell a company to be re-used.
What surprises me is that it seems to be a good sized market in Germany for someone to provide a service where they buy your company and later dissolve it, but the service doesn't exist (?)
The formal process in Germany seems simple enough. Just sign a sales contract at a public notary, the buyer replaces the CEO, and you're done.
Since this doesn't really seem to exist (?), I assume the potential liabilities for the buyer are so great that the service price would be much too high?
If you pay them to dissolve the company for you, they buy the shares from you and replace the board and the CEO. At that point, you're completely free from the company.
They then must take the 7-9 months needed to go through the whole dissolution process. There is a mandatory 6 month wait after announcing the dissolution to give lenders/sellers time to make claims against the company. This wait is 12 months in Germany.
There is also paperwork for the accounting, tax filings, etc.
The service takes care of all this as the new owners. Since they have done this literally thousands of times, they don't need to spend many man-hours on it. Therefore, the fee is fairly low, about 1000 dollars, of which 300 dollars are mandatory government fees.
In Sweden, you can of course also choose to dissolve it yourself, but nobody does that since it takes years, and it's pretty cheap to let someone else take care of it for you.
