Mixing personal and business money is how you lose your liability shield. Week 10 we separate completely.
By Week 10 your LLC (formed Week 4) gets its own bank account, its own debit card, its own bookkeeping software (Wave is free). Every dollar that touches the business goes through that account. Every personal expense stays personal. The IRS calls this 'corporate veil maintenance.' Lose the separation, lose the protection.
Open a business checking account in your LLC's name (Mercury, Bluevine, Relay — all online, free). Sign up for Wave Accounting (free) or Xero. Move 30 days of business income/expenses into the new account. Personal stays personal.
