Rockville is the seat of Montgomery County, Maryland, and a key stop on the technology corridor northwest of Washington. Its economy blends federal government work, life sciences and biotechnology, information technology and professional services. Many firms serve federal agencies as contractors or subcontractors, while research companies cluster along the corridor. The Rockville Town Square area and surrounding neighborhoods support restaurants, medical practices, law firms and a diverse community of immigrant owned small businesses.
Government contractors in Rockville need DCAA aware bookkeeping, timekeeping controls and indirect rate calculations to win and keep contracts. Biotech startups must track grants, research spending and investor funds carefully, and professional firms want clear project profitability. PSG provides disciplined monthly bookkeeping and fractional CFO leadership on budgets, burn rate, pricing and audit readiness for firms competing in this market.
Maryland levies state income taxes plus county income taxes that employers withhold, along with a statewide sales tax. Many businesses also file an annual report and personal property return with the state.
General information only, not tax advice. Rules change, so confirm specifics with a tax professional.
Yes. We work with Rockville 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, Maryland 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 Gaithersburg, Washington, Leesburg, Bowie and Frederick.

“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.”

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.
