Why sell with a US LLC from abroad? (Context / problem)

If you want to expand internationally, creating an ecommerce US LLC is a common path to access US customers, US marketplaces and payment rails. An ecommerce US LLC can make it easier to open a US bank account, accept payments via Stripe or other processors, and use fulfillment networks like Amazon FBA or US-based 3PLs.

Common problems for foreign sellers:

Difficulty opening a US bank account and getting an EIN without a US presence.
Payment processors (Stripe, Shopify Payments) require proper entity and banking details.
Managing US sales tax (nexus) and logistics from your home country.
Choosing the right platform (Shopify vs Amazon vs Etsy) based on product, margins and scale.

This guide explains practical steps to overcome those barriers and start to sell online US LLC products efficiently.

How to run an e-commerce business with a US LLC: Step-by-step (Solution / paso a paso)

Below is a concrete workflow with actions, required documents and typical timelines.

1) Form the LLC and get the essential documents

Action: Choose a state and form your LLC. Popular choices for non-residents include Delaware, Wyoming and Florida — each has different filing fees, annual requirements and privacy features.
Documents you’ll need: Articles/Certificate of Formation, Operating Agreement, Beneficial Ownership Information Report (BOIR) when required, registered agent.
Timeline: Formation can take 5–7 business days standard; with express services it can be done in 1 day.
Why it matters: You'll need the EIN and LLC documents to open a US bank account, register with Amazon or Stripe, and sign up for other services.

Practical tip: Use a service that files the EIN and acts as registered agent so you have the complete set of documents to operate immediately.

2) Obtain EIN and open a US bank account

EIN: Apply for an Employer Identification Number (EIN) — required for banking and many integrations. Non-resident owners can usually obtain an EIN for a US LLC.
Bank accounts: Remote-friendly banks like Mercury or Relay accept US LLCs formed by foreign founders (some plans include help opening them). Having a US bank account simplifies payments and reduces cross-border fees.
Timeline: EIN can be obtained within days; bank accounts often open in a few days to a couple of weeks depending on verification. Some providers streamline this process.

Action checklist:

Submit LLC documents + passport/ID for beneficial owners.
Link your US bank account to Stripe, Shopify or Amazon payout settings.

3) Choose your sales channels: Shopify, Amazon, Etsy

Shopify (Shopify LLC international): Best for brand control and direct-to-consumer sales. Set up a Shopify store, connect a payment gateway (Stripe or Shopify Payments where available), and install apps for fulfillment and tax calculation.
Amazon (Amazon LLC foreigner): Best for scale and discovery—Seller Central + FBA gives access to Prime customers. Be prepared for product listing requirements, UPCs, and Amazon’s seller verification.
Etsy: Good for handmade, vintage or craft products with lower entry complexity.

How to decide:

Use Shopify for branding and higher margins.
Use Amazon/FBA for reach and fulfillment simplicity if you can absorb fees.
Consider a multichannel approach: a Shopify storefront plus Amazon listings.

4) Payments: Stripe and alternatives

Stripe: Supports US LLCs but requires EIN and a US bank account for payouts; identity verification for beneficial owners. Stripe works well for Shopify and many custom checkout flows.
Alternatives: PayPal, Payoneer, or platform-specific processors (Shopify Payments) depending on eligibility.

Practical step: Set up Stripe once you have EIN + bank account. Test payments in sandbox before going live.

5) Fulfillment: FBA vs 3PL vs dropshipping

FBA (Fulfillment by Amazon): Amazon stores, picks, packs and ships your inventory. Good for fast delivery and Prime eligibility, but fees vary by size/weight—use Amazon’s fee calculators.
3PL (third-party logistics): Companies like ShipBob, ShipMonk and regional 3PLs can handle multi-channel fulfillment and often provide better unit economics for certain SKUs.
Dropshipping: Lower upfront inventory cost but weaker margin control and longer shipping times from suppliers.

Logistics checklist:

Choose US fulfillment to improve delivery speed.
Prepare barcodes/labels and inventory plan for inbound shipments.
Compare storage and pick-pack fees vs shipping cost savings.

6) Sales tax and compliance basics (nexus)

Concept: Sales tax nexus is the connection that requires you to collect and remit sales tax in a state. Nexus can be created by economic activity (sales thresholds), physical presence (warehouses, employees), or marketplace facilitator rules.
Practical approach: Track where you have inventory (e.g., FBA warehouses create nexus), use nexus monitoring tools (TaxJar, Avalara) and register to collect sales tax where required.
Advice: Sales tax rules differ by state and change frequently—es recomendable consultar con un contador o especialista en impuestos para tu caso específico.

7) Accounting, pricing and customer service

Use accounting software (QuickBooks, Xero) and connect your sales channels to reconcile revenue, fees, shipping and returns.
Price to cover product cost, platform fees (Amazon/Shopify), fulfillment, customs and margins.
Build clear return and shipping policies for US customers.
