The book
Start in Bulgaria
How do I start a business in Bulgaria?
The complete version of what this website carries in pieces.
By Dr. Dennis Kwiatkowski & Svilen Petkov
- Step-by-step guide to forming an (E)OOD
- Germany–Bulgaria tax comparison with worked examples
- Template documents and authority overviews
- Interviews with founders who have done it

How the book and the site fit together
The site is the current part: an article explains one topic, a calculator answers one question, the provider comparison helps with one choice. All of it is free and kept up to date.
The book is the connected part: the same material, in the order the decisions actually arrive — from “does Bulgaria fit at all” through to running the company. It unlocks nothing that is missing here. It orders what is scattered here.
Which is why no chapter on this site sits behind an email address, and no preview stops before the actual answer.

Who it is for / Who it is not for
Who it is for
- People seriously considering a Bulgarian company who want the whole process in one piece.
- Freelancers and solo founders comparing structures across countries.
- Entrepreneurs whose move and company setup belong together.
- Established companies evaluating Bulgaria as a location.
Who it is not for
- Anyone who needs a binding answer on their own case. That is what a tax adviser or a lawyer is for, not a book.
- Anyone looking for a loophole. Where your business is taxed is not decided by the registration, and the book says so as plainly as this site does.
- Anyone with a single question. It is very likely answered free of charge here — search for it before you buy anything.
- Anyone who needs today's figures. A printed book has a cut-off date; the site has a check date per statement.
Two editions
The German and English books are two separate titles with their own Amazon listings, not one edition with a translated blurb.

Who wrote it
Dr. Dennis Kwiatkowski and Svilen Petkov — the same two people who run this site. German commercial perspective, Bulgarian entrepreneurial experience; not a law firm and not a tax practice.
Disclosure
Start in BG is funded through book sales and voluntary reader support through PayPal. So we are recommending our own product here, and you should know that while reading it. Payments buy neither access nor advice, placement, or editorial influence. Purchase goes through Amazon; we publish no price, because it differs by marketplace and edition and a stale figure would be worse than none.
