vn.weldune.comUS market-access pack
The US market-access pack: the entity, EIN, bank, filing-calendar and vendor-onboarding paperwork a US customer expects, organized.
Selling through a US entity from Vietnam?
Here is what US rules require, organized in order: the entity, the EIN, the bank package, the filing calendar, the vendor paperwork.
The US market-access pack standardizes the five steps most founders improvise. It walks you through the publicly documented steps to a Delaware entity and an EIN, and organizes your information into a US bank-application package, a Form 5472 and Form 1120 compliance calendar, a sales-tax nexus check and a US vendor onboarding kit (W-9 or W-8, certificate of insurance, net terms). The same five documents every run, so the step you used to do by hand makes fewer mistakes.
It is not legal advice, does not form the entity for you, does not prepare or sign tax returns, and does not open bank accounts. Formation, tax, and banking decisions depend on your circumstances; confirm them with a US attorney and a US tax professional.

The obligations, by name
What a US customer's finance team asks a new foreign supplier for.
The pack's five components are named for the obligations they organize: the Form 5472 and Form 1120 compliance calendar; the sales-tax nexus check for the states you sell into; the vendor onboarding paperwork a US customer's accounts-payable team asks for before it pays a new supplier (W-9 or W-8, certificate of insurance, net terms); the EIN walkthrough; the bank-application package. Deadlines and penalties render only from verified sources; until this pack's variables are logged, every calendar row reads Confirm with your accountant.
