The Ravical ROI Survey Report
What AI is already delivering, measured
The accountancy profession is undergoing its most significant transformation in a generation. Firms that leaned into AI early are now seeing tangible returns, and measuring those returns has become a strategic priority, not just an operational one. This report shows what those firms are already seeing today, and what others can reasonably expect.
Why measure now
Clients are moving first: in a separate survey of 500 UK businesses, 71% had acted on an AI answer to a financial or tax question without checking with the firm they pay and 92% would pay more for advice they're not receiving today. This report is the first look at what firms already closing that gap are seeing — 47 advisers at 21 firms across Europe, most only a few months in, so today's numbers are an early baseline that's already moving.
Who did we interview?
In June 2026 we surveyed 47 advisers at 21 accounting, tax and advisory firms across Europe, from independent practices to full-service groups serving thousands of end clients. More than a quarter of survey results came in from partners or directors; the rest from the people in daily client work: accountants, tax advisers and client managers. Most have been using Ravical for only a few months, so these numbers are an early baseline.

Key finding 1
New revenue opportunities are the primary value driver
Ravical works on top of the firm's existing systems and data: it reads across clients' emails, files and financials, and flags additional revenue opportunities a person would have to sit down and look for: a subsidy, a tax optimisation, an anomaly in the numbers. Without being prompted, one in five respondents described work of a different level, not the same work done faster.

Key finding 2
Efficiency gains are reported across the board
Every respondent reported time gains. The average is 3.7 hours per adviser per week, and the median sits at the same level, so the number is not propped up by a few outliers. Over a year, that is more than four working weeks per adviser. And today's gains come almost entirely from single actions, an email, an analysis, a document. Workflows, which run whole chains of work across the client book in one pass, are only now rolling out. That is where the next jump lives.

Key finding 3
The move to value-based pricing has started
Measured at the Ravical customer firms furthest along this path. It comes from the same client book, with no new clients and no extra headcount: opportunities the platform spotted, plus work repriced to its outcome instead of the hours it took.

Revenue growth per existing client
"If we bill from our timesheets, we're basically giving all the efficiency gains away. It is the reverse move we want to make."

In conclusion
Early days, unmistakable signals
These are early days: habits take time to form, metrics take time to mature, and the move away from the billable hour is only beginning. Several advisers said plainly that they're still learning, and that their own numbers will look different a year from now. But the signal is already hard to miss, the hours are real and measured, and they're being reinvested in deeper advice, with pricing beginning to follow it.
