What Our Customers Say
“Our old accountant filed our taxes. Hartwell & Rowe changed how we run the company. The October planning call alone saved us more than their annual fee — twice now.”
“Three years of unfiled returns and I was terrified to open my mail. David took over every piece of IRS contact, got penalties abated, and set up a payment plan I can actually live with. I sleep again.”
“The monthly CFO sessions forced us to confront our pricing — we were undercharging our best clients by 30%. Revenue is up, workload is down. That conversation doesn't happen with a tax-season-only accountant.”

Before You Come
The things people ask most.
Do you offer free consultations?
Yes — the initial consultation is free, confidential, and typically 30 minutes. Bring your last two tax returns and current financials if you have them; you'll leave with a candid assessment and a written flat-fee quote.
How does flat-fee pricing work?
After the consultation, you receive a written annual quote covering the agreed scope — tax, bookkeeping, advisory, or a combination. Routine questions and calls are included; the meter is never running. If your situation changes materially, we re-quote before doing additional work.
Are you taking new clients?
We onboard a limited number of new business clients each quarter so service levels hold. Off-season (May–November) is the ideal time to switch — there's time for a proper onboarding and a planning session before year-end.
How is a CPA firm different from a tax-prep chain?
Licensed CPAs are bound to professional standards, can represent you before the IRS, and — in our model — work with you year-round on the decisions that determine your tax bill, rather than recording history each April.
