Big5 is a global alliance of accounting professionals and firms committed to collaboration, crossborder service delivery, and shared growth opportunities.

Big5 empowers independent firms and professionals to compete globally without losing their identity. Unlike the Big 4, Big5 promotes collaboration, not consolidation, and offers equityparticipation based on contribution

Big5 was launched by a team of global finance professionals led by qualified accountants with deep experience in international practice, technology, and regulatory frameworks.

To provide accounting professionals and firms with the tools, resources, and trusted network to
scale globally, serve international clients, and operate with integrity and excellence.

To establish a globally recognized, values-driven accounting platform that enables members to
thrive independently while collectively challenging the dominance of centralised firms.

No. Big5 is not a franchise or traditional association. It is a collaborative membership platform
where members maintain independence while benefiting from shared resources and referrals.

Big5 is built on integrity, innovation, ownership, and collaboration. These core values are reflected
in how members serve clients and support one another.

Yes. Big5 has a growing presence in over 98 countries and supports cross-border collaboration between members in the UK, India, GCC, EU, Africa, and beyond.

Big5 uses a secure escrow model to protect both clients and service providers. When a project is confirmed, the client deposits funds into an escrow account managed by Big5 or a third-party provider. The funds are only released to the service provider upon successful delivery and client
approval. This ensures trust, transparency, and payment assurance for both sides.
