Accounting Firms Can’t Afford to Sit Out the Sustainability Revolution


Regulators, clients, and banks are all demanding verifiable sustainability data — and they’re turning to whoever can deliver it fast and with credibility. Right now, most firms treat sustainability like admin work. But the next generation of accounting firms will treat it like assurance.


FiSM transforms sustainability from a reporting headache into a high-value advisory service — powered by financial data, not surveys.

FiSM helped our team turn sustainability compliance into a repeatable, billable service. — Partner, Mid-Tier Accounting Firm
