What a bookkeeper does
Bookkeepers handle the day-to-day: recording transactions, reconciling bank and credit-card accounts, running payroll, and producing monthly financial statements. They keep your books clean so tax filing is faster and cheaper. Many work in QuickBooks or Xero and bill a flat monthly rate based on transaction volume. For tax strategy or audited statements you'll still want a CPA.
