Tennessee's growth-focused CPA firm.
For growing businesses

Accounting built around your business.

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.

Why RiverRidge

Small firm. Intentionally.

Most CPA firms grow at any cost. We'd rather keep doing the work we love well — every return getting the partner's eye, quarterly calls with depth, and emails answered the same day.

i

You're not a number here

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.

ii

Responsive by default

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.

iii

Proactive, not reactive

Quarterly tax planning calls are baked into every engagement. We flag the move before April, not after.

What we do

Small business accounting, tax, and payroll — done well.

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.

Outsourced Accounting

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.

  • Monthly close & reconciliation
  • Management reporting
  • Controller-level oversight

Bookkeeping

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.

  • QuickBooks Online & Desktop
  • Cleanup & catch-up engagements
  • Monthly ongoing bookkeeping

Payroll

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.

  • Direct-deposit & tax deposits
  • 941/940, W-2, 1099 filings
  • New-hire & garnishment setup

Other Accounting Services

The work that doesn't fit a single label — software selection, controller support, process reviews, lender packages, and special projects scoped to your ask.

  • Accounting system setup & training
  • Lender & investor packages
  • Project-based engagements

Tax Planning & Preparation

Federal and multi-state returns for individuals, partnerships, LLCs, S-corps, and C-corps. Year-round planning so April doesn't become an event.

  • Individual & business returns
  • Quarterly estimated planning
  • Multi-state & entity filings

Tax Problems

IRS or state notice? Back returns, installment agreements, offers-in-compromise, or audit defense. We step in and handle the correspondence from here.

  • Notice response & audit defense
  • Back-return filing
  • Installment & OIC negotiation

The founder

Why AJ built the firm he couldn't hire.

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 flat monthly retainer for every client, partner-level attention on every return, and a standing promise to call growth-oriented owners before April, not after.

"I'd rather know every client's business inside and out than treat returns as paperwork. That's the whole thesis."

Who hires us

Growth-oriented businesses in Tennessee.

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.

How we start

Four steps from first call to first return.

Most new clients are onboarded in under two weeks. Here's what that looks like.

01

Free 30-min call

Talk to AJ. Explain the situation, the goals, the prior-year pain. We'll tell you honestly whether we're a fit.

02

Written proposal

A flat-fee engagement letter for the scope we discussed. You'll know the monthly or annual number before you sign.

03

Secure onboarding

Prior returns and QuickBooks access flow through our encrypted portal — secure, organized, and ready before the first close.

04

Ongoing partnership

Quarterly check-ins, proactive notices, and a CPA who already knows your business every time you call.

How we work

Three things that show up in every client engagement.

Responsiveness, clarity, and a CPA who thinks about the business before you do. Here's what that looks like in practice.

Proactive quarterly planning

Standing tax-planning calls each quarter — not just check-ins on what's owed, but conversations about distributions, equipment timing, and year-end positioning before the year is over.

Entity-structure savings

Real-money outcomes, not theoretical guidance. Year-two restructures from LLC to S-corp routinely translate to five-figure SE-tax savings the next April.

Fast notice response

A one-business-day commitment for the first response. Notices land, we read them, and a draft strategy is back in your inbox before the next morning's coffee.

Pricing approach

Flat-fee engagements.

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.

Where we work

One firm, serving all of Tennessee.

RiverRidge works with clients from Memphis to the Smokies. Meetings are by appointment — most happen by phone, Zoom, or in-person.

Statewide service

Tax, accounting, and advisory for growth-oriented business owners across the state. Secure portal, virtual meetings, and in-person when it makes sense.

Questions

Answers before you book.

The same questions come up on the first call. Here's what we tell people.

How responsive are you?

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.

Do you work statewide — or only in one part of Tennessee?

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.

How are fees structured?

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.

I got an IRS notice. Can you help?

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.

What if my books are a mess?

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.

Are you QuickBooks people or Xero people?

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.

Ready when you are

Thirty minutes with AJ. No pitch.

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.

Contact

Let's talk.

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.
