Frequently Asked Questions
What does a bookkeeper do?
A bookkeeper records all financial transactions, manages invoices and payments, reconciles bank and credit card statements, runs payroll, generates financial reports, and keeps your books organized so you and your accountant can make informed decisions.
How much does a bookkeeper cost?
Bookkeeper rates vary by location and scope of work. Part-time bookkeepers typically charge $20-$50 per hour, while full-service monthly bookkeeping packages for small businesses range from $300-$2,000 per month depending on transaction volume and complexity.
Do I need a bookkeeper if I use QuickBooks or other software?
Software handles the mechanics, but a bookkeeper ensures transactions are categorized correctly, accounts are reconciled, and your books are accurate. Mistakes in DIY bookkeeping often lead to costly tax errors. A bookkeeper saves time and prevents problems before they start.
