More than 2,000 advisers have adopted SimplyBiz's end-to-end investment system since it was launched six months ago.
The Centra service is available at no cost to members of SimplyBiz and it offers financial planning tools, product research, suitability reports and a centralised investment process.
It was launched in January following demand from SimplyBiz members.
Dan Russell, managing director of SimplyBiz Investment Services, said: "I am delighted to see how enthusiastically Centra has been adopted by members of The SimplyBiz Group.
"We invested heavily in the development and deployment of Centra, both financially and in terms of resource, with constant consultation with advisers throughout the process.
"Providing free Centra licences means that we have delivered the equivalent of over £2.5m of software to the firms we serve, at no cost.
"We are confident that it is the best system available for advisers today, and it is great to see our members are in agreement. In fact, we’ve had over 300 firms join the group since we launched Centra in March, demonstrating it is an attractive proposition to advisers across the market."
SimplyBiz has provided more than 100 face-to-face training events across the UK free of charge, which have been attended by some 1,100 advisers so far.
The Financial Technology Research Centre recently carried out an independent review of the Centra system which found it could save advisers two hours 59 minutes per case, which was a 66.3 per cent time saving when compared to a manual process.
