Frequently Asked Questions

How much does a CPA cost for a business in Houston?

CPA fees vary based on your business complexity, transaction volume, and service needs. At SDO CPA, basic bookkeeping starts around $300–$500 per month for a single entity. Full-service packages that include bookkeeping, tax planning, and advisory typically range from $1,000–$2,000 per month.
