Quatrro Business Support Services

What Quatrro Business Support Services does

Quatrro Business Support Services, operating as ContinuServe, is a privately held US-based outsourcing firm providing integrated back-office support to midmarket and SMB clients. The company consolidates finance and accounting, managed IT and cybersecurity, human resources, and advisory/design services into a single vendor relationship, replacing the fragmented multi-vendor model common among midmarket operators. As of March 2026, the company operates under the unified ContinuServe brand, which absorbed prior brands including QBSS operations and USWired following a multi-year acquisition strategy.

The company's core delivery is labor-led, executed by 2,300+ specialists across F&A, HR, and IT functions, serving approximately 1,200 clients spread across six verticals: multi-unit consumer (notably quick-service restaurant chains), industrials, nonprofits, private equity, professional services, and technology & SaaS. Named enterprise customers include Taco Bell, Pizza Hut, KFC, Burger King, IHOP, NAPA Auto Parts, Hewlett Packard, and Girl Scouts, while the technology stack is described as an integrated back-office platform with ISO 27001, ISO 9001, and SOC 1 (SSAE 18) certifications underpinning its managed services.

Commercially, the company runs an enterprise field sales motion targeting midmarket clients with quote-based, annual subscription recurring managed services contracts. Growth has been driven by a combination of organic expansion and acquisitions: Apparatus Solutions (May 2022, nonprofit sector), USWired (April 2022), and Robust Network Solutions (January 2023). A strategic partnership with Restaurant365 (November 2025) extends reach into multi-unit restaurant operators. The company is privately held, with prior investment from Trivest Partners and Veronis Suhler Stevenson (2019), and is led by Chairman and CEO CM Sharma with Mandeep Singh as COO. No proprietary AI/ML capabilities are disclosed in the available data.
