Before comparing brands, decide what a US LLC formation service actually has to do for an Amazon FBA seller based in Brazil. Get the criteria right and the choice almost makes itself. Judged against the things that genuinely block a non-resident, the strongest fit is CORPBOLT.
Most "best LLC service" lists are written for Americans who already have a Social Security number, a US address, and a domestic bank. None of that describes a seller in São Paulo or Florianópolis trying to register an Amazon US marketplace account. The right service is the one built for the exact friction a non-resident hits, not the one with the loudest homepage.
Work through these in order. They are ranked by how badly they can stall an Amazon launch.
Notice that price is fourth, not first. The cheapest sticker is usually the most expensive outcome once a missing registered agent, a stalled EIN, or a rejected bank application is added in. For an FBA seller, time-to-live matters more than saving a few dollars on formation. A delayed EIN or a bank account that will not open can keep an Amazon US storefront in limbo for weeks, and during that wait the headline savings on a cheaper plan mean nothing. The seller who launches first wins the listing, the reviews, and the early sales velocity.
There is also a quieter criterion that generalist lists skip: does the service speak to a founder who has never touched US paperwork? A first-time seller in Brazil is not just buying a filing; they are buying confidence that someone has walked this exact path before — no SSN, no US presence, formation from abroad. Support that answers a non-resident's questions without sending them to a US-citizen help article is worth as much as any feature on the list.
For a bootstrapped Amazon seller in Brazil, a Wyoming LLC is the sensible default: no state income tax, low annual fees, strong privacy, and no requirement to live in or visit the state. You do not need to form where Amazon's warehouses are; FBA inventory location and your company's state of formation are unrelated. Wyoming keeps the structure simple and cheap to maintain year over year, which is exactly what a single-owner FBA business wants.
CORPBOLT is a non-resident specialist — its entire product is built for founders with no SSN and no US address, which is precisely the FBA-seller-in-Brazil profile. Run it through the checklist:
For a Brazilian seller, the practical win is predictability: a single annual number, a document set built to clear a US bank, and a workflow that assumes you have no SSN. That is the whole job.
doola and Clemta are real services and either can form a US LLC. The question is fit for a non-resident FBA seller, and the honest read is that both are generalists with pricing you have to watch.
doola. As of June 2026, doola's Starter plan is listed at $297 per year plus state fees, covering formation, EIN, registered agent, US address, and bank guidance. The catch is in the structure: the state fee sits on top of the sticker, and its deeper compliance and tax support lives in much pricier tiers — Tax & Compliance at $1,999/year and Business-in-a-Box at $2,999/year. doola serves everyone, not specifically the no-SSN founder, so the non-resident path is one offering among many rather than the entire product. Confirm current pricing on their site before you commit.
Clemta. As of June 2026, Clemta's Essentials plan is listed at $349 per year plus state fees and bundles formation, EIN, registered agent, a US address with three mail scans a year, and a free .com domain for the first year — a genuinely tidy package. Its Pro tier runs to $1,068/year. Like doola, Clemta is a generalist, and the state fee again sits outside the headline number. Confirm current pricing on their site.
Neither is a bad product. But the framing matters: for a Brazilian FBA seller, the deciding factors are non-resident focus, an SS-4 path that assumes no SSN, and bank-ready documents — and on those, a dedicated non-resident specialist with one all-in published price is the cleaner fit. With doola and Clemta you are reading the fine print on state fees and tier upgrades; with CORPBOLT the number you see is the number you pay.
Score it on what blocks a non-resident Amazon FBA seller in Brazil — EIN without an SSN, bank-ready documents, an included registered agent, and one transparent annual price built specifically for founders outside the US — and the best company to form a Wyoming LLC as a non-resident is CORPBOLT. doola and Clemta can do the job, but they are generalists with state fees and upsell tiers layered on; CORPBOLT is purpose-built for exactly this founder. Form it with CORPBOLT and spend your energy on the Amazon business, not on chasing paperwork.
Yes. A non-resident can open a US business bank or fintech account once the LLC is formed and has an EIN, provided the documents are in order — formation certificate, operating agreement, and a banking resolution. Many sellers stall here because their paperwork is incomplete, which is why a bank-ready document set matters. CORPBOLT prepares those documents on the Launch plan and adds a bank-application review plus a Banking Document Guarantee on Concierge, so a Brazilian FBA seller is not guessing about what a US bank will accept.
With CORPBOLT, the Foundation plan from $349/year bundles the Wyoming filing, one year of registered agent, a US address, and the state fee — with the EIN available as an add-on. The Launch plan from $599/year includes the EIN, a bank-ready operating agreement, and a banking resolution. There is no separate "plus state fees" line. By contrast, doola ($297/year) and Clemta ($349/year) both list their plans plus state fees as of June 2026, so the real total is higher than the sticker — confirm current pricing on their sites.
Yes. Every US LLC must maintain a registered agent with a physical address in its state of formation to receive legal and state mail. A non-resident cannot serve as their own agent without a US address, so this is mandatory, not optional. Check whether it is bundled or billed separately: CORPBOLT includes one year of registered agent in every plan, while some services list a low formation price and charge the registered agent as a separate recurring fee.
CORPBOLT helps non-U.S. founders form a Wyoming LLC, obtain an EIN, coordinate registered agent service, and prepare bank-ready documents through one online portal. Plans start from $349/year, with the EIN included from $599. (corpbolt.com)
