- Step 1
Form your LLC
A handful of short questions, no legalese. Three minutes and your filing is on its way to the state.
- Step 2
We file your EIN
Once the state approves, our team files Form SS-4 with the IRS so your EIN letter lands in your dashboard.
- Step 3
Open Mercury with $125
Use our partner link to open your Mercury account. Hit the qualifying balance and the $125 bonus lands in your account.
What lands in your dashboard
Real documents, not promises.
Everything you need to operate a US LLC, in one place. Downloadable, signed, and yours to keep.
Stamped Articles of Organization
The official state-issued document that legally creates your LLC. Stored in your dashboard, downloadable as PDF.
EIN letter from the IRS
Your Federal Tax ID number, on the IRS confirmation letter. You need this to open a bank account, run payroll, or pay taxes.
Operating Agreement
A written agreement defining members, ownership, voting, and decisions. Drafted for your business activity, not a generic boilerplate.
Mercury account and $125 bonus
After your EIN lands, we send a tracked link to open your Mercury account. Hit the qualifying balance and the $125 bonus arrives in your account.
