Sioux Falls is the economic hub of eastern South Dakota, set along the Big Sioux River and its namesake falls in Minnehaha County. Financial services are a major industry, with banks and card issuers drawn by the state's favorable regulatory climate. Sanford Health and Avera make healthcare a leading employer. The city is a regional hub for agriculture, meat processing, retail and distribution, while a growing downtown supports restaurants, breweries and professional firms.
Sioux Falls healthcare suppliers and practices need revenue cycle visibility and payroll accuracy, while financial and professional service firms want clean client profitability. Agribusiness and distribution companies depend on inventory and seasonal cash planning, and contractors rely on job costing amid steady growth. PSG delivers accurate monthly bookkeeping and fractional CFO guidance on forecasting and financing.
South Dakota has no state individual or corporate income tax, but it levies a broad state sales tax, and cities add local sales taxes. Because sales tax applies to many services, invoicing needs care.
General information only, not tax advice. Rules change, so confirm specifics with a tax professional.
Yes. We work with Sioux Falls companies through a dedicated team that is entirely US based, combining Big Four accounting experience with years of operating experience across industries. Your team closes the books on a regular schedule, works inside the accounting tools you already use and looks at your numbers the way an operator would, not just a bookkeeper.
Typically bank and card reconciliations, accounts payable and receivable, payroll support, South Dakota sales tax tracking and monthly financial statements you can act on. Growing companies can add fractional CFO support for forecasting, budgeting and cash planning.
Usually when decisions start to outgrow the books: raising capital or bank financing, opening a new location, making key hires, tightening margins or preparing for a future sale. A fractional CFO adds forecasting and strategic guidance without the cost of a full time executive.
We also work with businesses in Sioux City and Mankato.

“If you want to sleep better at night, hire Phoenix Strategy Group.”

“PSG and David Metzler structured an extraordinary M&A deal during a very chaotic period in our business, and I couldn't be more pleased with our partnership.”

“PSG saved my dream. They helped us get our financials in order and renegotiate our lending agreements, pulling us through a tough financial crunch.”

“As our fractional CFO, they accomplished more in six months than our last two full-time CFOs combined. If you're looking for unparalleled financial strategy and integration, hiring PSG is one of the best decisions you can make.”

“Hire PSG if you want to make your life easier and have accurate data.”

“As a home service business owner, understanding complex financials and Unit Economics always seemed overwhelming—until we started working with Phoenix Strategy Group.”

Hi! I'm Sam, a financial leader who's managed operations from startups to $40M enterprises.
I've led licensing deals with Disney, Marvel, and Viacom, while overseeing products across 35,000 retail stores. Through SHK Financial, I've helped 15+ high-growth companies succeed, including recovering $2M in receivables for a major client and rebuilding a $10M ARR company's accounting system in 6 months. Now, as Chief Accounting Officer at PSG, I oversee 50+ revenue streams and help launch many successful 8-figure businesses.
My journey started uniquely - while studying finance at Fresno State, I taught both chess and accounting to students, teaching me that success in finance, like in chess, is all about strategic thinking and seeing several moves ahead.
