Symphony - APS

Over 25 Years, One Sector, Enduring Relationships

Symphony – APS (incorporating Advanced Professional Solutions) was founded in 1998 and developed a practice management platform, Advance, that was used by mid-to-large accountancy firms, with a strong presence in Australia, New Zealand and the UK. Best known as the engine for many sizeable practices, handling client management, time, billing, WIP and workflow. In the UK, it became a recognised name among top-100 firms precisely because it was built for the scale and structure those firms need.

Recognised. Accredited. Proven.

Introducing Symphony365

Over 25 Years. One Sector. Enduring Partnerships.

Symphony365 is the evolution of Symphony APS — a practice management and CRM platform dedicated exclusively to large and mid-sized accounting firms.

For over 25 years, we have worked alongside firms as long-term partners, not short-term vendors. Many of our clients have trusted Symphony for more than two decades. That longevity is not accidental — it reflects deep domain expertise, operational reliability, and systems built to scale with growing practices.

We built for accountants. We stay with accountants.

 

Continuity and Commitment.

Technology evolves. Relationships endure.

Symphony365 reflects 25 years of sector focus — and client partnerships that span generations of leadership within firms. We understand how accounting businesses operate because we have grown alongside them.

Practice management is not an accessory system. It is the operational backbone of your firm. Symphony365 exists to make that backbone stronger.
