RiverRidge works with growth-oriented business owners across Tennessee who want more than a form-filer. Every engagement starts by understanding how you actually operate — your books, your patterns, your goals — and is priced as a flat monthly retainer so you know the number before the work starts.
Most CPA firms want to grow. We'd rather stay small and keep doing the work we love well. When a roster gets too large, the work changes — every return stops getting the partner's eye, quarterly calls lose depth, emails take days. So we've drawn a line and we keep it.
With a small roster, AJ and the team know your business, your filing history, and your goals. We don't ask you to repeat context every year — we lead with it.
Direct communication, not a ticket system. When you email, you hear back from the CPA who knows your file — and if an answer needs research, you'll get an acknowledgment and a timeline.
Quarterly tax planning calls are baked into every engagement. We flag the move before April, not after.
A focused set of services for growth-oriented Tennessee business owners. Every engagement is scoped to your operation and priced as a flat monthly retainer.
A complete accounting function without the overhead of a full in-house team. Monthly close, reporting, and the advisory layer that turns numbers into decisions.
Clean, current books you can actually run the business from — whether we're setting up from scratch, cleaning up a backlog, or taking over ongoing.
Full-service payroll handled end-to-end. Direct deposit, tax deposits, quarterly and annual filings — and a real person to call when a question lands.
The work that doesn't fit a single label — software selection, controller support, process reviews, lender packages, and special projects scoped to your ask.
Federal and multi-state returns for individuals, partnerships, LLCs, S-corps, and C-corps. Year-round planning so April doesn't become an event.
IRS or state notice? Back returns, installment agreements, offers-in-compromise, or audit defense. We step in and handle the correspondence from here.
AJ Hosenfeld spent a decade inside the kinds of firms he'd never hire as a client. The ones where your return sits in a stack, where "your CPA" means the associate two desks over, where the partner you met during onboarding is the partner you never speak to again.
In 2016, he started RiverRidge to run the other way — a firm-wide commitment to staying small, a flat monthly retainer for every client, and a standing promise to call growth-oriented owners before April, not after. Not a growth target, a ceiling. Because the only way to keep the promise of personal service is to never take on more than you can serve well.
"I'd rather know twenty-five businesses well than three hundred by file number. That's the whole thesis."
Owner-operated companies across the state that have outgrown DIY bookkeeping and want a CPA who knows the books, not a form-filer. Every engagement starts with a free 30-minute call and a written, flat-fee scope — so you know what you're getting and what it costs before you sign.
Most new clients are onboarded in under two weeks. Here's what that looks like.
Talk to AJ. Explain the situation, the goals, the prior-year pain. We'll tell you honestly whether we're a fit.
A flat-fee engagement letter for the scope we discussed. You'll know the monthly or annual number before you sign.
Prior returns, QuickBooks access, and IRS 2848 power-of-attorney all flow through our encrypted portal.
Quarterly check-ins, proactive notices, and a CPA who already knows your business every time you call.
Responsiveness, clarity, and a CPA who thinks about the business before you do. The scenarios below are illustrative examples of the work we do — not quotes from specific clients.
We don't publish a rate card because every engagement is scoped to the work it actually takes. What we promise is how we price — a flat fee, set up front, documented in writing.
Every client gets a written scope and a flat fee — monthly or annual, depending on the work.
RiverRidge works with clients from Memphis to the Smokies. Meetings are by appointment — most happen by phone, Zoom, or in-person.
Tax, accounting, and advisory for growth-oriented business owners across the state. Secure portal, virtual meetings, and in-person when it makes sense.
The same questions come up on the first call. Here's what we tell people.
Yes. We intentionally keep the roster small so every client gets real attention. If we're at capacity, we'll say so on the first call — and we'll happily recommend other Tennessee firms we trust.
Emails, calls, and portal messages go to the CPA who knows your file — not a shared inbox or a ticket queue. Tax season is busy, but you'll always hear back from a real person.
Statewide. We work with owner-operated businesses from Memphis to the Smokies. Our secure portal and virtual-meeting setup makes geography mostly irrelevant for ongoing work, and we'll come in person when the engagement calls for it.
Yes. Plenty of clients use us only for annual tax prep and planning. If you want to add monthly bookkeeping or advisory later, we make it easy — but it's never a prerequisite.
Flat fees, not hourly. We quote a monthly or annual number based on a defined scope. That number is set before you sign, and won't change mid-year unless the scope does.
Yes — and don't respond to it yourself. Forward it to us and we'll build a strategy within one business day. Most notices have tight response windows, so the sooner we see it, the better.
That's normal. Most new clients come to us with books that need a cleanup. We quote the cleanup separately from ongoing work, so you know what you're signing up for on each side.
QuickBooks Online is our default, but we work with Xero and a handful of other platforms. We meet you where your books are, not the other way around.
If we're full, we'll tell you. If we're the right fit, we'll quote a fee and outline the scope on the same call. Either way, it's a useful conversation.
The form is the fastest way in — it lands directly in AJ's inbox and he'll be back to you inside one business day. Prefer to talk first? Call the office at (615) 549-6536.
