Positive Solutions says it expects at least 70 partners to become part of its new network model after it revealed further details of the proposition.
PosSol announced in January it was to restructure its pricing model to operate as a network and a national.
The new practice model will only be available for firms with a turnover of more than £150,000 and two or more IFAs.
PosSol partners can join the new model between July and September, after which it will be launched to the open market.
The firm says it intends to help member firms build their own brand presence and recruit IFAs into their practice through a flexible charging structure.
The network will include a compliance framework to give advisers protection and support.
FSA and FSCS levies will be passed directly to firms at cost. Charges for the model are yet to be confirmed.
A PosSol spokeswoman says: “This new model will be competitive while providing firms with a comprehensive support package.”
