Can I open the LLC myself, or is it advisable to hire a company that specializes in this?
Delaware state is an easy beginner friendly state to get LLC, you can open an LLC yourself, you also need a registered agent if you are not in the US.
Not legal/tax advice, but for most Amazon sellers the “best state” depends on where you’ll actually operate. If you’re living/doing business in a specific state, you often need to register there anyway (or register as a foreign LLC if you form in WY/DE).
Many people choose WY/DE for admin simplicity, but the savings can disappear if you still have to register/pay fees in your home state.
You can file yourself (state website + EIN), but if you’re not comfortable, paying a reputable filing service is fine, just avoid upsells you don’t need.
Key question: which state are you physically based in / where will you run the business?
Most online sellers prefer Wyoming or Delaware because they have low state fees, simple compliance, and no state income tax on out‑of‑state income (especially helpful for non‑US residents). Wyoming is cheaper and more privacy‑friendly, while Delaware is popular for bigger or investor‑focused businesses. Yes, you can open an LLC yourself directly through the state website, but if you’re outside the US, hiring a reliable formation company can save time and reduce mistakes with EIN, registered agent, and compliance filings.
