From Idea to First Payment: 30-Day Launch Plan for Non-Resident SaaS Founders

30 days is realistic if you sequence things correctly. The bottleneck is always the EIN (4-8 weeks if done DIY) — but with a service you can have it in 48 hours and unblock everything else.

Day 1-3: Foundation

• Day 1: Buy your domain. Set up Cloudflare. Buy Notion or Linear for project management.
• Day 2: Form your US LLC. Wyoming Pro ($299) if you want EIN included, or NM Basic ($149) if you'll DIY EIN.
• Day 3: Write your business plan in one page (problem, solution, ICP, pricing, GTM). Pick a name for the company.

Day 4-7: Documentation

• Day 4-5: Build the marketing site. Pricing page, terms of service, privacy policy, contact email at your domain (founders@yourdomain.com). Use a real template (don't use Lorem Ipsum).
• Day 6: Sign up for Resend or SendGrid for transactional email. Verify your domain (SPF + DKIM).
• Day 7: Get your EIN if Pro plan included. LLCora's Pro plan delivers Wyoming LLC + EIN in 48 hours.

Day 8-14: Banking & Payments

• Day 8-9: Open Mercury with your EIN + LLC docs + business URL. Approval in 2-5 days.
• Day 10-12: Once Mercury is approved, apply to Stripe. Use the Stripe approval playbook.
• Day 13: Add Stripe payment links to your marketing site. Set up Stripe webhooks for checkout.session.completed events.
• Day 14: Test the full payment flow end-to-end with a real $1 test charge (refund yourself).

Day 15-21: Build & launch MVP

• Day 15-19: Build your MVP. Whatever you can ship in 5 focused days.
• Day 20: Internal QA. Edge cases. Mobile.
• Day 21: Soft launch to your network. Post in 2-3 Slack/Discord communities you're already part of.

Day 22-26: First customers

• Day 22: Launch on Indie Hackers + Hacker News (Show HN).
• Day 23: Email everyone in your network. 30-50 personalized messages.
• Day 24: Reddit launch (relevant subreddits, NOT spammy).
• Day 25: Tweet thread + LinkedIn.
• Day 26: First customer hits. Capture the moment.

Day 27-30: Iterate

• Day 27-28: Talk to first 5 customers. Iterate on the things they complain about.
• Day 29: Set up Form 5472 reminder in your calendar (March 15 every year).
• Day 30: Ship the first iteration. Plan month 2.

Common mistakes that blow this timeline

• Waiting on EIN: 4-8 weeks DIY. Use a service to get it in 48h.
• No Mercury before Stripe: Stripe requires a US bank account to verify. If you apply to Stripe before Mercury, you'll get manual review.
• Generic site: Stripe rejects sites that look thrown together. Spend the time on the marketing pages.
• Skipping Form 5472: Even with $0 revenue, you owe an information return next April.

When this plan slips

• If your home country has unusual tax classification of US LLCs (Germany, sometimes): add 2 weeks for accountant consultation.
• If Mercury or Stripe rejects on first try: add 1 week for appeal.
• If you don't have a marketing site ready by day 6: pause and build it first. Skipping = Stripe rejection.

Tools you'll use

• Domain + DNS: Cloudflare ($10/year)
• Marketing site: Next.js + Vercel (free)
• Database: Supabase (free for MVP)
• Email: Resend (free 3K/month)
• Payments: Stripe (2.9% + $0.30 per US card)
• Banking: Mercury (free)
• LLC + EIN: LLCora Pro $299
