Its core technology consists of industry-standard accounting, audit, and tax preparation platforms with no proprietary AI or automation layer disclosed; client-facing delivery is supported by the iChannel secure document portal. The firm employs approximately 100 professionals across offices in South Burlington (VT), Lebanon (NH), and Ahmedabad (India), with the India office opened in November 2022 to provide offshore delivery capacity.

The firm generates revenue through professional services engagements billed on a per-project or retainer basis; pricing is not publicly disclosed and varies by service line, scope, and complexity, with multi-year engagements noted. Its go-to-market is relationship-driven and sales-led, supplemented by thought-leadership channels including Vermont Chamber of Commerce webinars, industry event sponsorships, newsletters, LinkedIn, and earned media such as Accounting Today coverage. Customers are concentrated in Vermont and New Hampshire but extend globally, spanning privately owned businesses, PE-backed portfolio companies, non-profits (foundations, schools, religious institutions, social service agencies), and sector-specialized verticals including manufacturing and distribution, food and beverage, construction and real estate, renewable energy, and technology. Named logos include Revision Military, Ben & Jerry's Homemade (through the Unilever acquisition), Bogner of America, All Earth Renewables, and Burr and Burton Academy.

Operationally, the firm is a partner-owned limited liability partnership with no disclosed parent company, institutional investors, or M&A history. The leadership bench is heavily sourced from Big 4 alumni (PwC, EY, KPMG, Deloitte) and other national firms (RSM, BDO), and GFC is a member of the Aprio Alliance of collaborative CPA firms. The firm holds CPA licenses in Vermont (#092.0000125) and New Hampshire (#00627) and has earned consecutive Accounting Today Regional Leader, Best Firms to Work For, and Vermont Business Magazine Best Places to Work recognitions, reflecting 65+ years of continuous operation.
