A professional firm built around Philippine entrepreneurs.
Acosa Accounting Office is the professional accounting and tax advisory firm founded by Mark Jim Acosa, CPA, MMBM — built to help Philippine entrepreneurs simplify compliance while making better business decisions.
While the Mark Jim Acosa website focuses on his work as an author, speaker, and educator, Acosa Accounting Office is where businesses engage our professional accounting services — accounting, taxation, payroll, compliance, financial reporting, and strategic business advisory.
Our philosophy extends beyond filing reports. Business growth begins with financial clarity, so we help businesses build systems, improve financial clarity, and grow with confidence — combining technical precision with a genuine understanding of what it takes to run a business.
To empower Philippine entrepreneurs through accurate financial information, reliable compliance, and practical business guidance that supports sustainable growth.
To become one of the most trusted accounting and advisory firms for Philippine MSMEs by combining technical excellence, innovation, education, and long-term client relationships.
