Larson Gross Expands Client Advisory Services Through Acquisition of ScaleUp Financial Solutions

Accounting firm Larson Gross has officially completed the acquisition of ScaleUp Financial Solutions, a strategic move designed to bolster its client advisory services and broaden its consulting portfolio. The transaction, which became effective on October 2, integrates ScaleUp into the expanding Larson Gross brand family, adding specialized expertise in fractional chief financial officer support, controller operations, and outsourced accounting. Leadership at Larson Gross noted that the integration aligns directly with the firm strategy to scale comprehensive advisory offerings while maintaining high-touch, relationship-driven service delivery for growing enterprises.

Strengthening Regional Advisory Capabilities

Headquartered in Bellingham, Washington, Larson Gross maintains a prominent standing as a regional industry leader in the western market. The firm operates five distinct office locations supported by 16 partners and 179 professionals, generating robust annual revenues. In early 2025, Larson Gross joined the platform network previously known as Crete Professionals Alliance, which subsequently rebranded to Current. This broader platform integration provides foundational infrastructure and advanced technology capabilities that support ongoing expansion initiatives across the organization.

• ScaleUp Financial Solutions specializes in outsourced accounting and controller operations.
• The transaction took effect on October 2, expanding regional consulting capacity.
• Larson Gross operates five offices across the Pacific Northwest region.

Cultural and Technological Alignment

ScaleUp was established by founder and partner Rachel Williams, who will transition alongside her team into the Larson Gross organization. Williams emphasized that the partnership benefits from deeply shared organizational values, specifically pointing to a mutual commitment to individualized client relationships. Furthermore, both organizations share an active focus on adapting to technological evolution, including the integration of artificial intelligence and advanced digital tools to enhance client value delivery.

Industry observers note that regional accounting firms continue to actively pursue strategic acquisitions to meet rising demand for outsourced financial leadership. By absorbing ScaleUp, Larson Gross positions itself to capture a larger share of the middle-market advisory sector, offering expanding businesses access to sophisticated financial oversight without the overhead of full-time executive hires. The combined operation expects to leverage the technological backing of the Current network to streamline service delivery and navigate ongoing industry shifts.
