1. Separate business money and build useful categories
Use a dedicated business account and payment method appropriate to your business, then record any owner money put in or taken out. Mixing grocery shopping, personal savings, and client payments makes it harder to know whether the business supports you. Keep receipts even when a bank feed imports the transaction; a merchant name alone may not explain the business purpose.
Create categories that support decisions: session sales, product sales, refunds, payment fees, studio rent, insurance, software, marketing, travel, contractors, equipment, and professional services. Ask your accountant how to classify assets, loans, taxes collected, deposits, and personal use. The IRS recordkeeping guidance explains why records should support income and expenses. A workable spreadsheet may suit a simple start; choose accounting software when reconciliation and reporting require more structure.
