Bookkeeping for South Florida Healthcare Practices

Are you running your practice blind?

Most small healthcare practices in Hialeah have one thing in common — the owner can't actually tell you how the practice is doing this month. We fix that. Specialized, local, and built around the way independent practices actually operate.

  • Dental
  • Family & Internal Medicine
  • Pediatrics
  • OB-GYN
  • Cardiology
  • Nephrology
  • Dermatology
  • Chiropractic
  • Veterinary
  • Optometry
  • and many more
The Real Problem

Does any of this sound like you?

These aren't hypothetical complaints — they're the exact phrases small healthcare practice owners use when they describe their finances. If even two of these sound familiar, it's not you. It's the way your books are being kept.

You don't have a tax problem. You don't have a discipline problem.

You have a bookkeeping problem.

Why 305accounting

What makes us different from your last bookkeeper

Most generalist bookkeepers can give you a Profit & Loss statement. Almost none can tell you what your hygiene production percentage is, why your collections ratio dropped this quarter, or what to fix before tax season. We can.

Healthcare-specialized

Dental, primary care, pediatrics, OB-GYN, cardiology, dermatology, chiropractic, veterinary, and more. We speak insurance reimbursements, lab fees, and provider productivity — not generic small business jargon.

Local to Hialeah

We're based in Hialeah and serve practices across Miami-Dade and Broward. In-person when it matters. Bilingual (English & Spanish).

Responsive within 1 business day

Email, text, or call. You'll never wait two weeks for an answer. We respond within one business day, every time. It's written into our engagement letter.

Monthly KPI dashboard

Overhead percentage, collections ratio, production by provider, supply costs versus benchmark. Every month. So you can actually run the practice.

CPA-ready books

Your CPA gets clean tax-ready books delivered every January. No scrambling, no $5,000 cleanup invoices, no surprises. We handle the handoff so they don't have to.

Plain English, no jargon

We translate your numbers into business decisions. If we send you a report, we'll also tell you what it means and what to do about it. That's the whole point.

Who I Am

Built by someone who's seen the messy books from the inside.

I'm a Hialeah local with a Master's in Finance and over a decade running the accounting department at a medical company. I've worked with auditors, prepared financials for SBA loans, sat across from buyers in due diligence, and seen every kind of mess a healthcare practice can make of its books.

I built 305accounting because I watched too many independent practice owners get charged generalist prices for generalist work — and then get blindsided every January when their CPA found six months of misclassified expenses. That's not a problem you fix with a different CPA. You fix it upstream, with a bookkeeper who actually understands healthcare.

We're not a faceless firm. I personally handle every client onboarding and the first six months of every engagement. I respond within one business day. I show up in person when it matters. That's the deal.

Who We Serve

Built for small and medium independent healthcare practices.

Our entire firm is designed around the way independent practices actually operate — solo doctor, small partnership, or growing practice. Whether you're a single dentist, a 4-provider OB-GYN clinic, or a small cardiology group, we know how to handle your books. If you're a chain or a Dental Service Organization, we're not a fit. If you're an independent owner, we probably are.

Dental Practices

General, specialty, pediatric, orthodontic, periodontal, oral surgery — independent practices with 1 to 5 providers.

Family & Internal Medicine

Solo and small-group primary care practices, including concierge medicine and direct primary care models.

Pediatric Practices

Independent pediatric clinics, pediatric specialty practices, and small group pediatric partnerships.

OB-GYN & Women's Health

Obstetrics, gynecology, fertility, and women's health practices with the unique billing complexity that comes with them.

Cardiology

Independent cardiology practices, including those with in-office diagnostics, echocardiography, and stress testing revenue.

Nephrology & Endocrinology

Kidney and endocrine specialty practices, including those with dialysis-related billing or chronic disease management programs.

Dermatology

Medical, surgical, and cosmetic dermatology — including practices with retail product lines and aesthetic services.

Gastroenterology & Urology

Specialty practices with procedural revenue, in-office surgical components, and complex insurance reimbursement workflows.

Orthopedics & Pain Management

Practices with imaging revenue, physical therapy components, durable medical equipment dispensing, and procedural billing.

Mental & Behavioral Health

Solo and small-group psychiatry, psychology, counseling, and substance use treatment practices.

Chiropractic & Physical Therapy

Single-doctor and small partnership practices with treatment plan billing, PI claims, and supplement retail.

Veterinary Clinics

Small animal, mixed-practice, and specialty (exotic, emergency, veterinary surgery) clinics.

Optometry & Ophthalmology

Independent eye-care practices with optical retail, specialty contacts, and surgical referral revenue streams.

ENT, Allergy & Pulmonology
