Professional services giant KPMG has posted a 13 per cent increase in sales to $1.37 billion for the 12 months to June 30‎.

The result continues the stellar run of the big audit and consulting firms, with Deloitte and EY also posting double-digit revenue growth.

The firms have outperformed the economy as governments and financial service clients draw on their expertise to deal with technology disruption, regulatory changes, and margin pressure.

KPMG chief executive Gary Wingrove said the result was another strong incremental increase which showed the firm's investment strategy set in train three years ago was on the right path.

KPMG's profits have risen for the third successive year, despite 11 acquisitions in the last two and a half years.

"We've got good bottom line growth as well, which allows us to invest and reward our people and our partners," Mr Wingrove said.

Mr Wingrove said all business lines had grown.

Management consulting clocked the fastest growth, up 33 per cent in the year. For the first time, advisory work makes up the majority of the firm's annual revenue, at 52 per cent or $712 million.

The slowest growing divisions were audit and tax. Audit, which accounts for 23 per cent of total income, grew 5 per cent. Tax, which accounts for 16 per cent of firm revenue, also grew at 5 per cent, bringing in $219 million in sales.

Organic growth

Mr Wingrove flagged further acquisitions as KPMG strives for double digit growth in the year ahead.

Acquisitions accounted for a mere three percentage points out of the 13 per cent uplift that KPMG achieved in the 2015-16 fiscal year. 

Acquisitions have not adversely impacted profitability, according to chairman Peter Nash.

"The way we've done our acquisitions has allowed us to increase partner returns without weighing the balance sheet," Mr Nash said.

"There is more debt on the balance sheet but it is a very modest amount and the balance sheet is very strong."

Mr Nash said technological change was behind much of the increased demand from the government and financial service clients.

"Both of those sectors are subject to very significant disruption," he said.

"In the case of government, the call on government to do more with less – what citizens expect of government and what governments have the capability to deliver is an equation that is going the wrong way for them."
