The 90-Minute Audit: Exactly What We Look For When We Charge $1,500
Most agencies bleed revenue through invisible cracks in their system. We're open-sourcing our $1,500 diagnostic framework. Learn the 5 leaks we find.

TL;DR: If you poured water into a bucket full of holes, you would not blame the water for leaking out. You would blame the bucket. Yet, thousands of founders spend their days obsessing over "more water" (leads) while completely ignoring the structural integrity of their bucket (operations). In our experience auditing service businesses, we find that the average agency loses between 40% and 60% of its potential revenue not because of bad marketing, but because of a broken backend. The leads are there. The interest is there. The conversion mechanism is simply failing to capture the value.
We charge $1,500 to perform a forensic "Deep Diagnostic" on a client's business. In that 90-minute session, we consistently uncover five specific "Revenue Leaks" that are silently killing profit margins. This post is an act of radical transparency. We are going to give you the exact checklist we use during those paid sessions. You can use this framework to audit your own business today. If you have the discipline to fix these five areas, you will likely double your revenue without spending a single extra dollar on ads.
The Cost of Ignorance
There is a reason doctors do not perform surgery in the hallway. If you walked into a hospital complaining of chest pain, and the surgeon immediately tried to crack your ribs open without an X-ray, an MRI, or blood work, you would sue for malpractice. The surgeon needs the data first. They need a diagnostic.
However, in the business world, "malpractice" is the standard operating procedure. Founders wake up with a revenue problem (the pain), and they immediately start prescribing random solutions. "I need to post more on LinkedIn." "I need to hire a setter." "I need to change my pricing." They are guessing. They are trying to perform surgery without an MRI.
At GrowthStack, we refuse to operate without data. Before we install any systems, and before we sign a growth partner retainer, we require a Deep Diagnostic. This is a 90-minute stress test of your entire client acquisition infrastructure. Clients often ask us why we charge for this. We charge because the result is not just a conversation. The result is a roadmap that usually reveals $50,000 to $100,000 in lost annual revenue.
Today, I am going to save you the $1,500. I am going to show you exactly what we look for. I am going to show you the five most common places where your money is hiding.
Leak #1: The Speed Vacuum (The "Ghost" Lead)
The first thing we do when we audit a company is something they never expect. We mystery shop them. 24 hours before our scheduled call, we go to their website. We find their contact form or their "Book a Call" calendar. We submit a lead using a personal email address. Then, we start a stopwatch.
The Audit Test
We are measuring "Speed to Lead." This is not a vanity metric. It is the single most accurate predictor of conversion rate. Data clearly shows that if you do not respond to a lead within five minutes, your chance of qualifying that lead drops by 80%.
Here is what usually happens during our audit:
- We submit the form at 2:00 PM.
- We receive a generic "Thank You" screen.
- We wait.
- At 4:30 PM, or maybe the next morning, we get a manual email from the founder asking when we are free to chat.
The Diagnosis
If this happens, you have failed the first test. You have entered the "Speed Vacuum." By the time you replied, that prospect had already visited three competitor sites, watched a YouTube video, and moved on to a different task. You are now chasing them. You are fighting for attention you already had and lost.
How to Fix It
You need an automated "First Strike" system. This does not mean a robotic auto-responder saying "We received your message." It means a value-based trigger that lands in their inbox within 60 seconds.
Subject: I saw your request (Next Steps)
Body: Acknowledgment of their specific problem, a link to a relevant case study, and a direct link to book a time.
If you fix this single leak, your conversion rate on existing traffic will double.
Leak #2: The "Zombie" Database
The second question we ask during the audit is simple: "Show me your list of leads from six months ago." Most founders look confused. They pull up a spreadsheet, or they open a cluttered Stripe dashboard. They point to a list of names and say, "These are the people who didn't buy." We ask, "When was the last time you spoke to them?" The answer is almost always, "I haven't."
The Audit Test
We calculate the "Dormant Asset Value." We take the number of leads generated in the last 12 months, subtract the closed clients, and multiply the remainder by the average product price. Often, we find a list of 300 to 500 people who raised their hand, expressed interest, but for some reason did not buy at that exact moment. The founder assumes these leads are dead. We know they are just zombies. They are asleep, waiting to be woken up.
The Diagnosis
If you do not have an automated "Re-Engagement Campaign" running in the background, you are burning cash. Timing is the only variable you cannot control. A prospect might love your offer in January, but they are too busy. By June, they are ready to buy, but they have forgotten you exist.
How to Fix It
You need to install a "Nurture Loop." This is a low-intensity, high-value email sequence that touches your database once a week forever. It does not need to be hard selling. It just needs to be present.
- Week 1: A case study breakdown.
- Week 2: A free resource or template.
- Week 3: A contrary opinion on the market.
When the prospect is finally ready to buy, you will be the only option they remember.
Is your bucket leaking?
You can try to patch these holes yourself, or you can let us do it for you. In our Deep Diagnostic, we analyze every step of your funnel to find the hidden profit you are leaving on the table.

This is a subtle leak, but it kills your lifetime value (LTV). We look at your pricing page or your proposal deck. We look for the "Yes or No" friction point. Most agencies have a binary offer structure: Option A: Do nothing (Cost: $0). Option B: Hire us (Cost: $3,000/month).
The Audit Test
We evaluate the "gap" between zero and your core offer. If the gap is too wide, you are losing a massive segment of the market. There are prospects who trust you and want your help, but they are not ready to marry you. They want to date you first. If you force them to choose between $0 and $3,000, 90% of them will choose $0.
The Diagnosis
You are missing the "Bridge Product." You need a way to capture revenue from people who are not ready for the retainer but are desperate for the solution. If you turn these people away, you are not just losing the initial sale; you are losing the chance to upsell them later.
How to Fix It
We implement the GrowthStack Hierarchy:
- University (Low Ticket): Sell them the blueprint or the course for $297. Let them DIY it.
- Advisory (Mid Ticket): Sell them the roadmap or the audit for $1,500. Let them pay for your brain, not your hands.
- Systems (High Ticket): Sell them the execution for $3,500+.
When you fix this leak, your "No" becomes a "Not yet, but try this." You monetize the rejection.
Leak #4: The Manual Labor Trap
This part of the audit is usually painful for the founder. We ask them to open their calendar. We look at their tasks for the last week. Then we ask a brutal question: "How many of these tasks could a robot do?"
The Audit Test
We look for "Copy-Paste" behavior. Are you manually sending invoices? Are you manually creating Google Drive folders for new clients? Are you manually copying leads from Facebook Ads into your CRM? Are you manually scheduling follow-up emails?
The Diagnosis
If you are doing these things, you are not a CEO. You are an expensive secretary. Every minute you spend on manual data entry is a minute you are not spending on strategy, sales, or delivery. This is an "Opportunity Cost Leak." It doesn't show up on your P&L statement, but it drains your energy and limits your capacity to scale.
How to Fix It
We identify the "Zero-Human Zone." Anything that happens the same way twice must be automated. New Client Onboarding: One form submission should trigger the contract, the invoice, the Slack channel creation, and the Welcome Email. Lead Management: The lead source should automatically populate the CRM and trigger the email sequence. We use tools like Zapier or Make to build these bridges. The goal is to remove the human element from the administrative layer entirely.
Leak #5: The "Hope" Strategy (Passive Inbound)
Finally, we look at your acquisition source. We ask, "Where did your last five clients come from?" Common answers: "Referrals." "I posted on LinkedIn and someone DM'd me." "They found my blog."
The Audit Test
We test for "Predictability." If you stopped posting content today, or if your referrals dried up tomorrow, would you still get leads? If the answer is no, you have a leak. You are relying on "Hope Marketing." You are waiting for the world to come to you.
The Diagnosis
You lack "Social Intelligence." Waiting for inbound leads is comfortable, but it is not scalable. A real business needs a way to go out and hunt. You need a mechanism to identify high-intent buyers before they even know you exist.
How to Fix It
We install an "Active Signal" system. Instead of waiting for leads, we use data to find them. Who is hiring a Marketing Director right now? (They have a budget). Who just raised Series A funding? (They have pressure to grow). Who is asking questions about your niche in public forums? We build a list of these "Signal-Verified" leads and we reach out to them with a specific, relevant offer. We do not spam. We solve problems they just admitted they have. This shifts you from being a "Passive Receiver" to an "Active Hunter."
The Pivot: Two Ways to Solve This
Now you have the list. You have the framework. You know exactly where the money is leaking out of your business.
- Speed: You are too slow.
- Database: You are ignoring old leads.
- Offer: You are too binary.
- Labor: You are too manual.
- Acquisition: You are too passive.
You have two choices on how to handle this information.
Option 1: The DIY Route. You can take this blog post, open your settings tabs, and start building. You can sign up for Zapier. You can write the email sequences. You can try to map out the automation logic. It will likely take you 40 to 60 hours to get it right. You will break things. You will get frustrated with API errors. But eventually, you might plug the holes.
Option 2: The Diagnostic Route. You can let us do it. You can book a Deep Diagnostic with us. We will get on a call, share our screen, and tear your process apart. We won't just tell you what is wrong; we will map out exactly how to build the fix. We will verify your speed to lead. We will audit your database assets. We will structure your offer ladder. We have done this hundreds of times. We know exactly where the errors hide.
Conclusion: The Cost of Waiting
The most dangerous number in business is the revenue you don't see. It is easy to count the money in the bank. It is hard to count the money that slipped through the cracks because you took three hours to reply to an email. Every day you operate with these leaks, you are paying a "Disorganization Tax." You are spending ad dollars to fill a bucket that has holes in the bottom. Stop fetching more water. Fix the bucket. The diagnostic takes 90 minutes. The results last the lifetime of your business.
Stop Guessing. Start Engineering.
Your business is a system. If the system is broken, the revenue will always be inconsistent. Let us perform a forensic audit on your sales process. We will find the leaks, quantify the loss, and give you a roadmap to fix it.
