Most solo operators set up their finances backwards. Here's the sequence that works — and why the order matters.
Everything else in your financial stack depends on this. Separate business income from personal income before you do anything else. It protects your personal assets, makes tax time manageable, and is required before any lender or card issuer will look at you as a business.
Who to open with: For most solo operators, Mercury or Relay. Both are free, digital-first, and built for this audience. Mercury is better if you want integrations; Relay is better if you want to separate taxes and expenses automatically.
Once your bank account is open, connect an accounting tool to it. Transactions will auto-import, invoices will sync, and you'll have a real picture of your cash flow for the first time. FreshBooks is the right choice for most solo operators billing clients for time or services.
Business credit is a separate profile from your personal credit score. It takes time to build — which is exactly why you should start now. Register with Nav (free) to see where you stand and get a roadmap.
Start with Nav Free →Business cards (Amex Business Gold, Chase Ink) and funding (Lendio, Fundbox) become available once you have 3–6 months of business banking history and a business credit profile in progress. Don't rush these — the foundation makes the applications stronger.
The right invoicing tool depends on whether you need accounting, client management, or just payment collection. See the invoicing guide → or compare HoneyBook vs Bonsai →
A single-member LLC gives you liability protection for $50–$500 in state filing fees. It doesn't automatically save you taxes — but it protects your personal assets and enables S-Corp election later. See the full LLC vs sole proprietor guide →
Self-employment tax is 15.3% on top of income tax, with no employer withholding it for you. The fix is a dedicated tax account that funds automatically on every payment. Read the self-employment tax guide → or estimate your quarterly payment →
