Transact's head of marketing Malcolm Murray believes Financial Planning will "come into its own" over the next few years.
Writing on the IFP blog, Mr Murray said many Financial Planning firms benefitted from being RDR-ready ahead of the deadline.
He said: "We are sure that the Financial Planning firm with all the investment that has gone into creating it will increasingly come into its own over the next few years.
"Such firms have been building on the firm foundations of recurring income paid for by clients for several years. Many advisers have left it too late and will struggle either to cope with the cash flow problems or have enough income to invest in the infrastructure that changing old business models require."

Transact is a long-term supporter of the Institute of Financial Planning and is a corporate member.
Mr Murray said this rule would also apply to platforms adjusting to RDR. The market share of the top five platforms has fallen to 70 per cent from 90 per cent in 2010, according to figures from the Platforum.
He said: "Some of the old models have yet to show a profit and face problems even adapting to adviser charging, re-registration or offering a wide range of investments such as investment trusts, EDFs and structured products despite having plenty of notice."
