Frequently asked questions
How do I choose the right accounting firm in Boston?
Look for firms that offer the specific services you need, such as tax preparation, bookkeeping, or payroll. Check credentials (CPAs for tax and audit work), read recent client reviews, and ask about experience with businesses like yours before committing.
What should I bring to an initial meeting with an accounting firm?
Bring recent tax returns, current financial statements, bank statements, payroll summaries, and any notices from tax authorities. Having documentation on hand helps the firm assess your situation and give a clearer estimate of time and cost.
How much do accounting firms typically charge?
Fees depend on the scope of work, the firm’s expertise, and local market factors; some work by the hour while others offer flat fees for specific tasks. Always request a written estimate or engagement letter that outlines services, timelines, and billing terms.
