How to Know If Your Client Acquisition Is Actually Working
You run marketing campaigns. You network with pediatricians. You answer the phone when families call. But how do you actually know if any of it is working?
For ABA clinic owners and clinical directors, client acquisition effectiveness is one of the most important business metrics to understand—yet it often goes unmeasured or misunderstood.
This matters because poor measurement can hide serious problems. Long waitlists might look like success when they actually signal intake friction. Steady inquiries might mask the fact that families are dropping off before their first session.
This guide is for BCBAs who run clinics, clinical directors balancing care quality with growth, and anyone responsible for getting families into services. You will learn how to define acquisition effectiveness in plain language, which metrics to track first, where to get the numbers without expensive software, and how to run simple audits and experiments to improve your results—all while keeping ethics and capacity at the center.
A note on ethics and HIPAA: Any system that tracks client information must follow HIPAA guidelines. Document consent at intake. Store data securely. If a tool holds identifiable client information, ensure you have a Business Associate Agreement in place. Acquisition should never outpace your ability to deliver quality care.
Clear Definition: What We Mean by Client Acquisition Effectiveness
Client acquisition effectiveness is your clinic’s ability to identify, attract, and successfully enroll families into therapy through a structured, ethical system that balances conversion with clinical capacity and readiness.
That is the one-sentence definition your team can use. Notice it includes more than just marketing volume. Effectiveness means families move from first contact to first session—and they are appropriate matches for the services you provide.
The measurable outcomes that show acquisition is working include your inquiry rate, intake completion rate, time-to-first-session, and how well new clients fit your clinical capacity. Effectiveness is both a quantity measure (are enough new families coming in?) and a quality measure (are they the right fit, and are they receiving timely care?).
When you talk about cost metrics like Customer Acquisition Cost (CAC), define the term for your team. CAC equals your total sales and marketing expenses divided by the number of new clients acquired. This helps you understand what you are paying to bring each family through the door.
Short Ethics Reminder
Acquisition must always match your capacity and care standards. If you cannot serve families at the intensity their treatment plans require, enrolling more clients harms everyone—families, staff, and your clinical reputation.
Avoid language in your marketing that promises outcomes or pressures families. Ethical acquisition means being honest about what you offer and who you can help. See our [Ethics & capacity guide](/mastering-aba-business/client-acquisition/ethics-capacity) for more on this topic.

Why This Matters: Business and Clinical Signals to Watch
Poor measurement can hide problems for months or even years. You might see high inquiry numbers and assume everything is going well, but if your intake completion rate is low, something is creating friction. Maybe your intake forms are too long. Maybe response times are too slow. Maybe families are discovering you cannot serve their location or insurance.
Simple measures help clinic leaders make fair choices. When you know your time-to-first-session is creeping upward, you can investigate whether it is a scheduling problem, a credentialing bottleneck, or a capacity issue. When you track source data, you can see which referral partners are sending families you can actually serve—and which are sending mismatches.
Measurement is tied to ethical practice. When you track these numbers, you protect families from unnecessary waits. You protect staff from overloaded schedules. You make decisions based on data rather than guesses.
One-Line Examples (Anonymized/Hypothetical)
Consider a clinic seeing high inquiries but low intake completion. This pattern often points to intake friction—perhaps the process takes too long, or families are not hearing back quickly enough.
Now consider a clinic with steady intake numbers but an overloaded schedule. This is a capacity problem. Acquisition is technically working, but the clinic risks burning out staff or providing lower-quality care.

Key Metrics to Track (What to Measure and How to Calculate It)
Start with a short list of essential metrics. You do not need a dozen KPIs to begin. These five will tell you the most important parts of the story.
Conversion rate (inquiry to intake) tells you what percentage of families who contact you actually complete intake. Divide completed intakes by total inquiries, then multiply by 100. If 50 families inquired last month and 20 completed intake, your conversion rate is 40 percent.
Cost per lead (CPL) measures how much you spend to generate each inquiry. Divide total marketing spend by the number of leads generated. If you spent $500 on ads and received 25 inquiries, your CPL is $20. Note that CPL does not tell you about lead quality—only what you paid to get the inquiry.
Customer Acquisition Cost (CAC) measures the total cost to acquire a paying client. Add your sales and marketing expenses together, then divide by the number of new clients acquired. This includes staff time, software costs, and ad spend.
Time-to-first-session (TTFS) measures how long it takes from a family’s first contact to their first actual session. Subtract the timestamp of first interaction from the timestamp of first session. For most clinics, keeping TTFS under 10 days for non-urgent cases is a reasonable goal.
First-month continuation is a basic quality check. What percentage of new clients are still active after their first month? Low first-month retention might signal that your acquisition is bringing in families who are not a good fit—or that something is going wrong in early care.
Metric Quick-Reference
Each metric serves a specific purpose. Conversion rate shows where families drop off. CPL shows marketing efficiency. CAC shows total acquisition investment. TTFS shows operational speed. First-month retention connects acquisition to care quality.
Decide when to include referral sources versus paid sources. Some clinics track these separately because referral sources typically have lower CPL and higher conversion, which can skew your overall numbers if blended.

Measurement Setup and Data Sources (Where to Get the Numbers)
You do not need expensive software to start measuring acquisition effectiveness. Small clinics can begin with a minimal stack: a spreadsheet, a standardized intake form, and a calendar.
Your tracking spreadsheet needs a few key fields: date of inquiry, lead source (how the family found you), current status (inquiry, intake scheduled, intake completed, first session completed), and next step owner. Add fields for first contact date and first session date so you can calculate TTFS.
Your intake form should capture source data. Use both a visible dropdown asking “How did you hear about us?” and hidden fields that capture UTM parameters from digital sources. This combination covers both online and offline referral paths.
Common data sources include your intake logs, scheduling system, any CRM you use, ad platform reports (like Google Ads or Facebook), and referral tracking notes. If you track referrals manually, standardize how you record partner names so you can run reports later.
HIPAA note: Any system storing identifiable client data requires HIPAA-safe handling. Document your data flows. Get consent at intake for marketing communications. If you use a CRM, ensure it has a Business Associate Agreement in place.
An upgrade path makes sense when your tracking spreadsheet becomes unwieldy or when you need more automation. At that point, consider a simple CRM designed for healthcare or a practice management system with built-in reporting.
Minimal Setup Checklist
Your minimal setup should include a single tracking spreadsheet with required fields (date, source, status, next step), standardized intake form fields to capture source and consent, and a weekly calendar event to review your numbers.
Download the minimal setup checklist and spreadsheet to get started. For step-by-step guidance, see our [Step-by-step measurement setup](/mastering-aba-business/client-acquisition/measurement-setup).
Attribution Basics for Small Teams (Simple Models You Can Use Today)
Attribution answers the question: which touchpoint gets credit for bringing this family to your clinic? For small teams with limited resources, simple models work best.
First-touch attribution assigns 100 percent of the credit to the first interaction that introduced the lead. If a family first found you through a Google search, that search gets full credit—even if they later saw a Facebook ad before calling.
Last-touch attribution assigns 100 percent of the credit to the final interaction before conversion. If that same family saw your Facebook ad right before calling, the ad gets full credit.
Each model tells a different story. First-touch helps you understand how families discover you. Last-touch helps you understand what finally prompted them to act.
A simple multi-touch approach works well for clinics with mixed channels. One low-effort option is to split credit 50/50 between the first and last touchpoints. Another option is position-based attribution: 40 percent to first touch, 40 percent to last touch, and 20 percent distributed across any middle interactions.
Be careful about over-interpreting attribution when your sample sizes are small. If you only have 15 new clients this month, statistical noise will make attribution data unreliable. Use consistent models over time and look for patterns across quarters rather than weeks.
A One-Page Decision Guide
Use first-touch attribution when evaluating new referral partnerships or trying to understand which channels build initial awareness.
Use last-touch attribution when making conversion-focused changes, like testing new intake form language or adjusting your follow-up process.
Use simple multi-touch when you have mixed channels and families typically contact you multiple times before enrolling. This gives credit to both awareness-building and conversion-driving touchpoints.

Practical Intake Funnel Audit: A Step-by-Step Checklist
Running a funnel audit helps you find where families are dropping off between discovering your clinic and attending their first session. You can complete a basic audit in one week.
Define your funnel stages first. Most clinics use four: discovery (how families find you), inquiry (when they contact you), intake scheduling and completion (paperwork, assessment, insurance verification), and first session. Track volume and drop-off at each stage.
For each stage, check specific friction points. At the inquiry stage, are your intake forms capturing lead source? Is your response time under 24 hours? At the intake stage, is paperwork causing delays? Are families getting stuck waiting for insurance verification? At the first session stage, are no-shows high? Are families canceling because of scheduling conflicts?
Red flags include slow response times (over 48 hours), missing source fields on intake forms, high drop-off between inquiry and scheduled intake, and TTFS over two weeks for non-urgent cases.
Quick wins include adding a required “How did you hear about us?” field, setting an auto-response to acknowledge inquiries, and reducing intake form length.
One-Week Audit Plan
Day one: log your seven most recent inquiries and note their sources. Day three: track time from inquiry to first contact for each case. Day five: check scheduling steps and paperwork delays for those same cases. By end of week, you will have a clear picture of where friction exists.
Use the 1-week audit worksheet to run this process. For a detailed walkthrough, see our [Intake funnel audit checklist](/mastering-aba-business/client-acquisition/audit-checklist).
Channel-by-Channel Tactics and What to Measure for Each
Different acquisition channels require different tactics and different metrics. Here is what to focus on for each major channel.
Referrals from pediatricians, schools, and diagnosticians are often the highest-quality leads for ABA clinics. To strengthen these partnerships, provide value first—share educational materials, offer to present at their staff meetings, and make it easy for them to refer. Track referral-to-intake rate for each partner by dividing intakes from that partner by total referrals from them. This shows you which relationships are worth nurturing.
Website and SEO drive families who are actively searching for services. Simple changes can improve your contact form conversion rate. Make forms short (name, phone, reason for contact, source question). Place your phone number prominently. Use clear calls to action. Measure contact form conversion rate by dividing form submissions by total visitors.
Paid ads require careful ethical messaging and conversion tracking. Avoid language that promises outcomes or uses pressure tactics. Focus on providing information families need. Measure cost per lead and track downstream conversion to see how many paid leads become completed intakes. Compare first-month retention for paid leads versus organic leads to check lead quality.
Events and partnerships (like community health fairs or parent support groups) can build awareness and generate leads. Measure leads per event and follow-up conversion rate. After each event, track how many attendees became inquiries and how many became clients.
Consent note: Always get consent for marketing communications. Capture this at intake with clear language about how you will use contact information.
Quick Channel Checklist
At intake, ask families how they found you and capture their answer in a standardized field. When evaluating referral partners, consider both volume (how many referrals they send) and fit (how many of those referrals are appropriate for your services and complete intake).
Grab the channel tracking template to organize your channel data. For detailed tactics, see [Channel tactics and KPIs](/mastering-aba-business/client-acquisition/channel-tactics).
Capacity and Ethics Alignment: Match Growth to Care
The most important rule in acquisition: do not enroll more clients than you can serve at the agreed intensity. Growth that outpaces capacity harms families, exhausts staff, and damages your reputation.
Estimate your clinical capacity with a simple calculation. Multiply available clinician hours by the average number of clients per hour, then compare that to your current caseload. If you are at 90 percent or higher of capacity, be cautious about active outreach.
Manage waitlists ethically by communicating clearly with families. Give realistic wait-time ranges upfront. Check in proactively every four weeks. Offer interim resources or referrals to other providers when appropriate. Never use waitlist position to pressure families into services they do not need.
When capacity is full, pause acquisition. Update your website to reflect limited availability. Notify referral partners so they can direct families elsewhere temporarily. This protects families from waiting and protects your team from overload.
Ethical Guardrails (Plain Language)
Obtain consent before marketing or follow-up communications. Document where client information is stored and who has access. When making growth decisions, prioritize continuity of care over volume. Never let financial pressure push you to enroll families you cannot adequately serve.

Practical Dashboards and Templates You Can Use Today
A good dashboard makes your acquisition data visible and actionable. You do not need complex software—a well-designed spreadsheet and a one-slide summary can work for most clinics.
Your tracking spreadsheet should include these fields: Inquiry ID, Date of Inquiry, Lead Source, Lead Source Original (first touch), Campaign ID, Contact Method (form, phone, email), Intake Scheduled Date, Intake Completed (yes or no), First Session Date, Current Status, Next Step Owner, and Notes. Make Lead Source a required field to reduce “unknown” entries.
A simple intake funnel diagram shows drop-off at each stage. You can create this in a slide presentation or even on paper. Show the number of families at each stage (inquiries, intake scheduled, intake completed, first session attended) and the conversion rate between stages.
Your one-page weekly dashboard should show inquiries by source, inquiry-to-intake conversion rate, TTFS trend, provider utilization, and cost per lead if applicable. Update it weekly. The intake owner should update the raw data; the clinical director should review it monthly.
Files to Include in the Kit
Your template kit should include an editable tracking spreadsheet, a one-page intake funnel diagram (PDF or image), and a weekly dashboard slide (editable). Each file should have clear instructions about who updates which fields and how often.

Common Mistakes and Troubleshooting (What to Watch For)
Even clinics with good intentions make measurement mistakes. Here are the most common errors and how to fix them.
Over-relying on one channel without measuring fit leads to blind spots. If all your referrals come from one pediatrician but you never check conversion or retention for those referrals, you might miss quality problems. Diversify your channels and track outcomes for each.
Mis-attributing referrals because source fields are empty or inconsistent makes your data useless. When half your entries say “unknown” or “other,” you cannot make informed decisions. Standardize your source field with a picklist, require it at intake, and train staff on why it matters.
Ignoring retention and treating acquisition as an isolated metric gives you false confidence. High inquiry numbers mean nothing if families drop out after one month. Always connect acquisition metrics to early retention as a quality check.
Collecting identifiable client data without HIPAA safeguards puts your clinic at risk. If your tracking spreadsheet lives on an unsecured personal computer, or if you use a marketing tool that is not HIPAA-compliant, you have a compliance problem. Audit your data flows and fix gaps immediately.
Quick Fixes
Standardize the source field on intake forms by using a required picklist with clear options. Add a single weekly review meeting to catch trends early—30 minutes with your intake coordinator can surface problems before they become crises. If capacity metrics exceed safe thresholds, pause outreach until you have room to serve new families well.

Next Steps and Prioritized Experiments (Small Tests You Can Run Fast)
Improvement comes from testing. Here are low-cost, low-risk experiments you can run to improve acquisition effectiveness without disrupting care.
Response-time test: Measure your current time from inquiry to first contact. Set a goal to cut that time in half for two weeks. Track whether conversion improves. Time required: 2-3 hours to set up; ongoing attention during the test. Cost: none. Signal: inquiry-to-intake conversion rate.
Lead-source capture fix: Add a required “How did you hear about us?” dropdown to your intake form plus hidden UTM fields for digital sources. Run for one month. Track whether your “unknown” bucket shrinks. Time required: 1-2 hours for form changes. Cost: none. Signal: percentage of leads with known source.
Intake form simplification: Remove non-essential fields from your intake form. Track contact form conversion rate for two weeks before and after. Time required: 1 hour. Cost: none. Signal: contact form conversion rate.
Referral partner test: Select one referral partner and track their referrals exclusively for eight weeks. Compute referral-to-intake rate for that partner. Time required: minimal (tracking only). Cost: none. Signal: referral-to-intake rate for that partner.
For each experiment, document your hypothesis, primary metric, and timebox. After the experiment, decide whether to adopt the change, adapt it, or stop.
3-Step Experiment Plan
Plan: define your hypothesis and the metric you will watch. Run: set a short timebox (two to four weeks works well for most tests). Review: look at the data and decide whether to adopt, adapt, or stop.
Stop or pause any experiment if it harms capacity or client experience. The goal is to learn quickly without creating new problems.

Frequently Asked Questions
What is client acquisition effectiveness for an ABA clinic?
Client acquisition effectiveness is your clinic’s ability to attract families, convert inquiries into completed intakes, and ensure those families are appropriate matches for your services and capacity. Quality and capacity matter as much as raw numbers.
Which metrics should I track first?
Start with inquiry-to-intake conversion rate, time-to-first-session, lead source, and first-month retention. CAC is optional if you have no paid marketing spend—focus on the basics first.
How can we track referrals while staying HIPAA-compliant?
Capture source at intake using a standardized picklist. Document your data flows and consent at intake. Use non-identifiable tracking fields (like “Referral – Dr. Smith” without client names) and store everything in secure, HIPAA-compliant systems.
What is a simple attribution model for a small team?
First-touch attribution gives credit to the first interaction; last-touch gives credit to the final interaction before conversion. For a low-effort multi-touch approach, split credit 50/50 between first and last touchpoints. Choose based on what decision you are trying to make—first-touch for awareness, last-touch for conversion.
How often should we audit our intake funnel?
Do a quick weekly check looking at volume and any obvious outliers. Run a deeper monthly audit examining conversion trends at each funnel stage. If you see a sudden drop in conversion or your waitlist grows rapidly, run an immediate audit to find the cause.
How do we avoid growing faster than we can serve?
Estimate capacity by calculating available clinician hours times slots. Set a hard threshold—such as 85-90 percent of full schedule—at which you pause outreach. Communicate openly with referral partners and families when capacity is limited. It is better to say “we cannot accept new clients right now” than to enroll families you cannot serve well.
Conclusion: Center Ethics, Measure What Matters, and Start Small
Client acquisition effectiveness is about more than marketing metrics. It is about knowing whether your clinic is successfully connecting families with care—and doing so in a way that protects everyone involved.
Start with a clear definition your team shares. Track a small set of metrics: conversion rate, time-to-first-session, lead source, and first-month retention. Build a minimal measurement stack you can actually maintain. Audit your funnel regularly to find friction points. Match acquisition to capacity so you never enroll more families than you can serve well.
The experiments and templates in this guide are designed to help you learn quickly without disrupting care. Try one small test this month. Review the results. Decide what to do next. Improvement compounds over time.
Ethics should guide every decision. Acquisition that harms families—through long waits, pressure tactics, or overloaded clinicians—is not effective acquisition. It is a problem waiting to happen.
Download the full template kit (audit checklist, tracking spreadsheet, dashboard slide) and the experiments planner to put these ideas into practice. Your families deserve care that starts with a clinic that knows what it is doing—from first contact to first session and beyond.
