The cash-pay clinic marketing guide: reviews, recalls and real math

A practical marketing plan for practices paid by the patient. Google Business Profile, reviews, referral tracking, recalls, and a full CAC and LTV example.

A cash-pay practice lives or dies by one number: what it costs to win a patient versus what that patient is worth over time. Everything else, the ads, the Instagram reels, the logo redesign, is detail. Most clinic owners have never written those two numbers down, which is why most clinic marketing budgets are set by mood.

This guide covers the four channels that actually move a small practice, in order of return, and then walks through a complete CAC and LTV calculation with real dollars, so you can decide with arithmetic instead of adjectives.

Start where the patients already are: Google Business Profile

Before a patient reads your website, they read your Google Business Profile. It is free, and for a local clinic it usually outperforms every paid channel per hour invested. The checklist:

• Primary category chosen precisely. "Psychologist" beats "Medical clinic" if that is what you are. Google matches searches to categories, not to your poetry.
• Every field filled. Hours, phone that someone answers, services with prices if you publish them, and 10 to 20 real photos of the space and the team. Profiles with photos get materially more direction requests and calls.
• The booking link. If your software gives you an online booking page, put that link in the profile. A patient who can book at 11 pm without calling is a patient your competitor without online booking just lost.
• Answer the Q&A section yourself before strangers do it for you.

One hour to set up, fifteen minutes a month to maintain. No other channel comes close at that price.

Reviews: the compounding asset

Patients choose between two unknown clinics the way you choose between two unknown restaurants: count the stars, read three reviews, done. Volume and recency both matter, so the goal is a steady drip of reviews, not a one-time push.

The mechanism that works without being annoying: ask right after a satisfaction survey, and only ask the happy ones. Send a short survey after each visit (two questions is plenty: a 0 to 10 score and a free text box). Whoever scores you 9 or 10 gets a follow-up message with the direct link to your Google review page. Whoever scores lower gets a "sorry, tell us more" message and a fix, which is worth more than the review anyway. If your software sends post-visit surveys automatically, this whole loop runs itself.

Two rules that keep you out of trouble:

• Never reply to a review with anything that confirms the person was a patient. "We're sorry you feel that way, please call us" is fine. "Your appointment on the 12th" is a HIPAA problem. This applies even when the review is unfair, especially when it is unfair.
• Do not pay or trade for reviews. Platforms remove them and the FTC has fined businesses for it. Asking honestly after a good visit is allowed and is enough.

Measure the referral source, or you are guessing

Every new patient should be asked one question at intake: "How did you hear about us?" and the answer should be stored on the patient record, not in the receptionist's memory. After 90 days you will have the most valuable marketing report a small clinic can own: patients and revenue per source.

Practices that run this report usually discover two things. First, word of mouth and Google's free surface bring in more patients than the paid ads. Second, the paid ads still matter, because they feed the pool that later refers. You cannot manage the mix until you can see it, which is exactly what a patient CRM with a referral source field and reporting by source gives you.

Recalls: the cheapest revenue you will ever book

The most expensive patient to win is a stranger. The cheapest is the one who already trusts you and simply has not come back. Recall campaigns automate that: dental cleanings every 6 months, dermatology checks yearly, follow-ups at 3 months, botulinum toxin at 12 to 16 weeks. The message is one automated SMS or email: "It's been 6 months since your last cleaning, tap here to book."

The math is lopsided. Sending an SMS costs cents. If even 15 to 20 percent of recalls convert on a $150 visit, a list of 200 due patients returns $4,500 to $6,000 for an afternoon of setup. Set the rule once ("if visit type X happened, send message Y after Z days") and it runs forever. Just make sure you have TCPA consent for texting on file from intake, fines run $500 to $1,500 per message, and keep the recall clinical and dry rather than promotional.

Recalls also interact with retention economics in a way owners underestimate. Bain's research puts the profit effect of a 5 percent improvement in retention at 25 to 95 percent, and a single recurring therapy patient at $150 a week is roughly $7,800 a year. If recurring revenue is your model, we went deep on the structure in memberships, packages and recurring revenue.

The CAC and LTV example, with every number shown

Now the arithmetic that should govern the budget. The cast: a solo therapy practice charging $150 per session, running modest Google Ads plus the free channels above.

Step 1: total monthly acquisition spend.

Item	Monthly cost
Google Ads budget	$450
Landing page and tools, amortized	$100
Your time on GBP and reviews, 3 h at $50	$150
Total	$700

Count your own hours. Marketing that only works because your labor is free is not working.

Step 2: the funnel, with conservative rates.

Stage	Rate	Count
Ad clicks at ~$11 average CPC		40
Click to inquiry (call or booking form)	25%	10
Inquiry to booked first visit	70%	7
Booked to actually showed	85%	6

That show rate assumes you send reminders. Without them, no-shows run 15 to 20 percent or worse, and every lost first visit inflates your CAC. The fix is cheap and covered in how to reduce no-shows.

Step 3: CAC. $700 spent, 6 new patients seen. CAC = $700 / 6 ≈ $117 per new patient.

Step 4: LTV. The average new therapy patient in this example stays for 10 sessions (many stay 4, some stay 40, use your own median once you have data). Revenue: 10 × $150 = $1,500. Apply a contribution margin of about 60 percent after room, software, cards fees and admin: $900 of contribution per patient.

Step 5: the ratio. LTV / CAC = $900 / $117 ≈ 7.7 to 1.

The common benchmark says a ratio of 3 to 1 or better means you should spend more, not less; below 1.5 to 1 the channel is burning cash. At 7.7 to 1 this practice's problem is not the ad budget, it is capacity, which is a pricing question: if demand outruns your calendar, the answer is usually raising prices, and we wrote the whole playbook for that in how to price cash-pay services.

What moves the ratio most, in order:

1. Retention. Moving the average from 10 to 12 sessions lifts LTV 20 percent with zero extra ad spend. Recalls, follow-up scheduling before the patient leaves, and the survey loop do this.
2. Show rate. From 85 to 95 percent cuts effective CAC by about 10 percent.
3. Inquiry response speed. An inquiry answered within 5 minutes converts several times better than one answered in 4 hours. Studies also suggest 25 to 30 percent of calls to practices go unanswered and most callers do not call twice.
4. CPC and ad copy. Last, not first, despite being where owners fiddle most.

What not to spend on yet

Honesty section. A solo or small group practice usually should not start with: TV or radio, generic brand campaigns, sponsoring the local 5K for visibility, or an agency retainer above $1,000 a month before the tracking above exists. None of these are measurable at your scale, and unmeasurable marketing is a donation. Likewise, if your growth model is employer contracts or insurance panels, this whole cash-pay playbook is the wrong one and an agency with payer experience will serve you better. Different types of practice need different setups, and it is fine to admit yours is not the one we serve best.

The one-page plan

1. Complete your Google Business Profile this week. One hour.
2. Turn on post-visit surveys, route 9s and 10s to the Google review link.
3. Add "how did you hear about us" to intake and store it per patient.
4. Set up recall rules for your top 3 visit types.
5. Run $400 to $600 a month of tightly targeted local ads.
6. On the first of each month, pull one report: patients and revenue by source, CAC, average sessions per patient. Fifteen minutes. Adjust one thing.

Do that for six months and you will know your numbers better than 90 percent of practices, including much bigger ones.
