Cofunds has launched its personal pension plan after completing its testing stage.
The Cofunds Pension Account, administered by Suffolk Life, will enable investors to upgrade to its MasterSipp product if necessary.
Cofunds says the account's charging structure favours investors who use other areas of the platform, such as collectives or ISA wrappers, rather than just the pension plan.
Sales and marketing director Alastair Conway says: "Advisers asked us to develop a simple wrapper that made the most of the benefits of an integrated platform - and that is what we have done.
"They can apply online, it's managed online and is embedded into the heart of the online research, administration and reporting services on the platform."
The launch comes as Cofunds CEO Brett Williams says the platform is evolving to offer all the features of a full "wrap".
