Payroll Companies & Payroll Services in Gillette, WY

Casey Peterson, LTD is a regional CPA and financial advisory firm. It serves businesses, organizations, and individuals across the rural plains of Wyoming, Nebraska, and South Dakota. Wyoming employers comparing payroll providers can reach the firm through its offices in Gillette and Torrington. The firm handles payroll as one part of a broader accounting practice rather than selling it as a standalone software product. That arrangement suits owners who want one team to coordinate their payroll, books, and tax work.

Payroll within a full accounting relationship

The firm places payroll under its accounting services line, next to bookkeeping and financial reporting. Its goal is to take recordkeeping off the owner's plate so the owner can focus on running operations. Because the same practice also prepares tax returns, payroll records can feed directly into year-end obligations.

For example, the firm sends clients seasonal reminders to submit their 1099 information before a December cutoff. The site does not name specific payroll software, pricing tiers, or HR add-ons, so buyers who need those details should ask the Gillette office directly.

Services available through the firm include:

• Payroll handled as part of accounting engagements
• Bookkeeping and financial reporting
• Audit and assurance engagements
• Business consulting, valuations, and strategic planning
• Tax preparation and planning for businesses and individuals
• Wealth management and financial planning through an affiliation with Avantax Planning Partners

Industries and communities served

Much of the firm's work centers on rural economies. Agriculture is a major focus, including farm and ranch clients who need guidance as their industry changes. The firm also highlights government entities, healthcare providers, nonprofits, and tourism and hospitality businesses, and its intake form lists construction as well. Its healthcare focus appears in its GAAP podcast series.

One episode covered PBJ staffing reports for nursing homes and how that data affects facility star ratings, a topic where payroll records and regulatory compliance overlap.

Background, locations, and approach

Beyond its two Wyoming offices, Casey Peterson has locations in Chadron, Gordon, and Rushville, Nebraska, and a drop box in Mullen. In South Dakota it has offices in Rapid City, Martin, and Faith. Its team includes shareholders, income partners, client managers, associates, and branch administrators. The firm describes itself as a group of financial strategists rather than simple number crunchers.

It emphasizes putting people first, honesty and integrity, careful attention to detail, and creative problem-solving. It has received ClearlyRated's Best of Accounting award for five consecutive years.

The firm also offers several practical conveniences. Clients can opt into text messaging through Clerk Chat to receive deadline reminders, document requests, closure notices, and direct messages from their accountant. Invoices can be paid online. A resource center provides a glossary, a calendar of tax and financial due dates, and audit and tax tools. For a Wyoming business that wants local access and a single firm covering payroll, bookkeeping, and tax, Casey Peterson is a reasonable option to evaluate.
