Small Business Fundamentals

Medical school taught you medicine. It didn't teach you business. This section fills the gap — the bookkeeping, cash flow, tax, and financial literacy basics every DPC owner needs to run a healthy practice.


Why This Section Exists

Most physicians open a DPC practice with excellent clinical skills and almost zero business training. That's not a criticism — it's the system. Medical education has no room for a P&L statement, a chart of accounts, or a quarterly tax deposit.

But a DPC practice is a small business. And small businesses fail not because the product is bad, but because the owner runs out of cash, misreads their numbers, or gets blindsided by taxes.

This section is your crash course in running the business side of the practice. It's not legal or tax advice — it's the working vocabulary you need to make good decisions and have intelligent conversations with your accountant, banker, and bookkeeper.


What This Section Is (and Isn't)

It is:

  • Plain-English fundamentals of small business finance
  • Enough knowledge to avoid the worst mistakes
  • A framework for talking to professionals
  • Practice-agnostic — these principles apply to any small business

It isn't:


The Five Things That Will Get You in Trouble

If you remember nothing else from this section, remember these:

  1. Commingling money. Never run personal expenses through the business account, or vice versa. It's the fastest way to lose liability protection and confuse your books.
  2. Ignoring cash flow. You can be "profitable" on paper and still bounce checks. Cash in the bank is what pays the rent.
  3. Forgetting quarterly taxes. As a self-employed physician, no one is withholding taxes for you. The IRS still wants quarterly payments. Skipping them means penalties and a catastrophic April surprise.
  4. Not reading your own statements. If you don't look at your P&L and bank balance monthly, you don't know if your practice is healthy. Your bookkeeper can keep the books — only you can run the business.
  5. Confusing revenue with profit. $20,000/month in membership dues is not $20,000/month in take-home pay. Understand the difference before you spend it.

Educational Content Only

This section is general small business education. It is not tax, legal, or financial advice. Tax law, accounting standards, and regulations change. Always consult a qualified CPA, bookkeeper, or financial advisor for decisions specific to your practice.
