Partners & recommended tools

Services we recommend for forming a U.S. company, business banking, getting documents to the IRS, and preparing for the Enrolled Agent exam. Short list, no filler — only tools we have used or vetted ourselves.

How we're compensated

Some links on this page are affiliate or referral links — if you sign up through them, the company pays us a commission at no extra cost to you (exceptions are labeled on the card). Partners never see, review, or influence our editorial content, and our guides never rank or recommend services in exchange for payment. See our editorial standards and how we make money.

Stripe Atlas

Delaware C-corp or LLC with Stripe built in

Stripe's own incorporation product — strongest when you plan to raise U.S. venture funding or want payments wired in from day one. We link Mercury's partnership invite, which discounts the setup fee.

  • Delaware C-corp or LLC formation
  • EIN + bank account + Stripe payments setup
  • Standard startup legal templates

Not an affiliate link — this is Mercury's public partnership invite (a lower setup fee than the standard price). We earn nothing from it.
