And remember, there are only 3 invoices you have to pay: 1) the notary (it was €196 in my case 4 years ago), 2) Handelsregister (€150), 3) IHK (€40 for the first year of operation). Bundesanzeiger Verlag comes a litte bit later. Don’t forget to do the Transparenzregister. Everything else you can ignore.
