Sell anywhere. Be compliant everywhere.
Ecommerce businesses cross state lines faster than they realize. Sales tax nexus kicks in at $100,000 per state. FBA inventory creates physical nexus. We map every state you owe sales tax in, file the permits, and connect to your filing tool.
Built around how e-commerce actually operate.
Three things you will not get from a generic formation site.
Sales-tax nexus tracking
Partners flag the day you hit a state economic-nexus threshold.
Multi-state for inventory
Foreign qualify wherever you hold inventory or have FBA stock.
Banking partners ready
Mercury, Brex, and Relay accounts that open the same week as your formation.
For sellers that cross state lines.
From first sale to multi-state operator.
Home state, Wyoming, or Delaware depending on your structure and goals.
We pull your historical sales by state and map where you have economic nexus.
Permit applications filed in every state where you owe sales tax.
States where you have FBA inventory often require foreign qualification beyond just sales tax.

How customers like you use the platform.
"I sold on Shopify and Amazon and had no idea I owed sales tax in 14 states. They filed in 11 (3 covered by marketplace facilitators). I sleep again."
"Amazon kept letting copycats list under our brand. The trademark opened up Brand Registry and the knockoffs were gone in 60 days."
"Inventory financing through their partner opened up a season we would have missed. Funded in 11 days, not the 6 weeks the bank wanted."
