We deliver value-added audit and assurance services to our clients, helping them manage their fiscal responsibilities with prudence and foresight.

See Overview

Audit approach overview
Our audit approach will allow our client's accounting personnel to make the maximum contribution to the audit effort without compromising their ongoing responsibilities
Annual and short period audit
At P&A Grant Thornton, we provide annual and short period financial statement audit services that go beyond the normal expectations of our clients. We believe strongly that our best work comes from combining outstanding technical expertise, knowledge and ability with exceptional client-focused service.
Review engagement
A review involves limited investigation with a narrower scope than an audit, and is undertaken for the purpose of providing limited assurance that the management’s representations are in accordance with identified financial reporting standards. Our professionals recognize that in order to conduct a quality financial statement review, it is important to look beyond the accounting entries to the underlying activities and operations that give rise to them.
Other Related Services
We make it a point to keep our clients abreast of the developments and updates relating to the growing complexities in the accounting world. We offer seminars and trainings on audit- and tax-related matters, such as updates on Accounting Standards, new pronouncements and Bureau of Internal Revenue (BIR) issuances, as well as other developments that affect our clients’ businesses.
