Just one in three advisers expect their business revenues to be mostly generated from fees after 2012, according to research.
Teamspirit, which commissioned the research, says the findings suggest IFAs will diversify their businesses in the run up to the RDR.
A third of firms surveyed say they expect to be doing more than 50% of their business on a pure fee basis after the RDR is fully introduced at the end of 2012.
Teamspirit says the remaining 67% will want to diversify their businesses, moving away from simply offering investment advice, in order to expand their revenue streams.
Advisers are also planning to undertake more business generation initiatives this year, with 70% saying they are focused on finding new clients, rather than re-broking old business.
The majority of firms (77%) plan to continue operating as a full IFA business in the future, but 19% are unsure of how their business model will look post-2012.
A significant number of firms are also moving towards offering direct online services for clients, with 41% saying they have ambitions in this area.
Jo Parker, CEO of Teamspirit, says: "IFAs continue to be highly resilient and entrepreneurial in taxing economic conditions and it is interesting how many are looking to embrace direct transactions as part of their business model."
