01 / Overview

The foundation every marketplace application checks

Marketplaces, payment providers and suppliers all want to know who they are dealing with. A properly formed US LLC, with matching documents and a tax ID, answers that question and keeps your business details consistent across every application.

We guide the formation from state choice to the final paperwork, then make sure your company details line up exactly with what Amazon, Walmart and other marketplaces will verify. Consistency at this stage prevents most setup delays later.

02 / What’s Included

What LLC formation support includes

Guidance and paperwork, organized in the order marketplaces need it.

State Selection Guidance

A clear comparison of state options, fees and ongoing requirements, so you choose with the full picture.

Formation Filing Support

Your company registration (Articles of Organization) prepared with you and filed with the state, with a registered agent, the official in-state contact every LLC needs.

EIN Application

Help applying for your Employer Identification Number, the federal tax ID that banks and marketplaces ask for.

Operating Agreement

A standard operating agreement, the document that sets out who owns and runs the company, prepared for your review.

Document Pack

Formation documents, EIN confirmation and business details organized for account applications.

Yearly Filing Reminders

State renewals and yearly federal filings noted, including the extra IRS form for foreign-owned LLCs, so your company stays in good standing.

03 / Options

Choosing a state

There is no single best state. These are the questions that decide it.

Where You Live

Residents and non-residents

US residents often form in their home state. Non-residents usually choose a state with simple filings and low ongoing costs.

Ongoing Costs

Annual fees and reports

States differ on yearly report fees, state taxes and renewal rules, which add up over time.
