Armstrong, Backus & Co

What Armstrong, Backus & Co does

Armstrong, Backus & Co., LLP is a privately held, full-service public accounting firm headquartered at 515 West Harris Avenue, Suite 200, San Angelo, Texas, founded in 1961 by William H. Armstrong, CPA and operating continuously for more than six decades. The firm employs nine partners and over eighty-five staff under Managing Partner James L. Sanderson, CPA, and serves individuals, private and public businesses, and non-profit organizations across West Texas.

The firm delivers its services across five core lines — Audit and Assurance, Client Accounting Services, Tax Services, Payroll Services, and Financial Services — and supplements these with nine industry-specific practice areas: Agriculture, Commercial, Construction, Employee Benefit Plans, Estate and Trust, Government, Not-for-Profit, Oil and Gas, and Real Estate. Its underlying technology stack centers on a cloud-based virtual client accounting platform with 24-hour client access, the Clientaxcess client portal, Microsoft 365 productivity tools, and payment-processing integrations (Smart Pay ACH, CPA Charge, IRS Direct Pay). Financial services, including securities, investment advisory, and insurance, are delivered through a core affiliation with Avantax Investment Services, allowing licensed professionals to operate across Texas, New Mexico, Oklahoma, Arkansas, New York, Iowa, and North Carolina.

The business model is relationship-led professional services delivery: clients engage the firm directly via its single San Angelo office on a quote-based, project- or engagement-priced basis (no public pricing). Revenue is generated from recurring tax, audit, payroll, bookkeeping, and wealth management engagements supplemented by industry-specific advisory. Distribution is purely direct — there is no reseller, channel, or productized software offering — and the firm is privately owned by its partners with no external parent, venture backing, or disclosed revenue figures.
