CredenCash: Healthcare Credentialing Cash Flow Bridge & Runway Calculator for New Practices

You asked people to poke holes, so here's the biggest one: $20k is almost certainly not enough if you're taking insurance. The credentialing grind is what kills small practices — payer enrollment takes 3-6 months, and you can't bill until it's done, which means rent, the physician, and staff all get paid while zero insurance revenue comes in. Your first paid claims land 30-90 days after your first patient visit. Plan for 6 months of operating expenses in cash, not 2-3. Two practical things from your list: 1. Don't sign a lease until credentialing is underway and your medical director is locked in. The director isn't a checkbox — the Florida clinic license lives or dies on having a legit one who actually reviews charts. A paper director who ghosts you is how clinics get shut down. Vet that person like a co-founder. 2. Starting with one physician at 10 patients/day is the right instinct. But run the revenue math at your expected payer mix before committing — at typical IM reimbursement, 40 visits/week doesn't cover a physician salary plus overhead in month one. That's fine as long as your cash buffer covers the ramp. The surprise expenses I always see in healthcare startups: EHR + clearinghouse fees, billing (in-house hire vs \~6-8% outsourced), OSHA/HIPAA compliance setup, and front-desk turnover — you'll probably hire that role twice. On the confidence question: nobody feels 100% ready. The signal I'd look for is whether you've talked to a few physicians who'd actually refer to you and one honest practice owner who'll share real numbers. If those conversations check out, that's your green light — the rest is execution.

Medical practices are too complicated to run with smaller margins. Liability / malpractice insurance itself runs into thousands and with the amount of student debt clinicians take, they would like to work at possible non-profits in order to get student debt forgiveness. I have no idea about your networking but wish you the best.
