Fiske bounced back into the black in the six months to the end of November posting a pre-tax profit of £19,000 against a loss of £662,000 last time.
The group said its operating loss fell by 85% to £109,000 from £708,000 in 2015.
Chairman Clive Harrison said: "We are now reaping the benefits of our substantial investment in a leading edge, integrated, back and front office system which has been an important factor in our total revenue rising by 15% to £1,410,000 in the first half (2015: £1,226,000).
"We have also seen an improvement in our fee revenue which was driven in part by the integration of our ISA business onto the new platform.
"Underlying fee revenue continued to grow as we gradually migrate our clients onto a fee based structure."
