A U.S. entity built
for cross border commerce.
Selling into the U.S. on Amazon, Shopify, TikTok Shop, or DTC? You need a real U.S. entity, a U.S. bank account compatible with marketplace payouts, and bookkeeping that survives scrutiny when a marketplace flags your account. Prolify builds that back office, and tells you honestly which pieces are live and which are coming.
Who this is for
What Prolify covers
for e-commerce.
Formation, banking, bookkeeping, and filings, built for how you actually sell.
LLC Formation, Matched to You
A written recommendation on the state that fits your operation first, then we form your LLC. No guesswork.
EIN & a Marketplace-Ready Address
EIN with no SSN required, a registered agent, and a real U.S. street address: the kind marketplaces actually verify.
Banking Built for Payouts
A banking application prepared and routed for you, compatible with Amazon, Shopify, Stripe, and PayPal payout flows.
Marketplace Bookkeeping
On eligible plans, we reconcile marketplace fees, refunds, chargebacks, and FX so your books match your settlements.
Year-End Filings, Coordinated
Licensed partners handle your filings, including the Form 5472 information return where it applies to your LLC.
An Operating Calendar That Knows Inventory
Every state deadline tracked, including the obligations your FBA inventory creates in states you didn't plan for.
Sales tax: the honest status
Sales tax registration and ongoing filings are coming soon, prioritized for e-commerce. Join the waitlist. Today we coordinate with sales-tax specialists for operators who need filings now, and we surface nexus exposure (inventory, thresholds) during the compliance audit so you know where you stand.
Recommended plan: Compliance + Tax at minimum, Managed Back Office once payout volume makes bookkeeping support worth it.
Common mistakes we help you avoid
Wrong address on file
Forming without checking the marketplace's address and verification requirements first.
Personal accounts for payouts
Running payouts through a personal account breaks reconciliation before it starts.
Inventory-driven nexus
Letting FBA inventory sitting in a third state create obligations nobody planned for.
Missed Form 5472
Missing the Form 5472 filing obligation that applies to most foreign-owned single-member LLCs.
Common questions
We provide a real U.S. street address, not a PO Box, which is the address type marketplaces require. Marketplace verification also depends on your documents and account details; we prepare those to match before you submit.
