The first shift was from improving the work to building the firm
Peter opens the workshop with Brock Hartzler at roughly $30K in monthly revenue before their campaign and over $90K a month within the following 12 months. The conversation is organized around three connected functions: marketing, sales, and service delivery. Brock’s description of the journey is less polished than a single growth formula and more useful because of it: each solved problem revealed the next point of resistance.
Before investing in paid growth, Brock felt confident in the accounting product. He knew it could always improve, but another one or two percent of service refinement would not produce the growth he wanted. He needed to work on the firm rather than only inside it. Organic growth existed, but it was not moving quickly enough, and he believed the immediate need was simply to get in front of more moving-company owners.
Brock found Peter through an advertisement while attending a moving-industry conference. The experience reinforced his view that paid advertising could buy awareness faster than waiting for organic reach. He did not claim expertise in copywriting or funnel building; he wanted people who were good at those jobs to create the system and tell him what they needed from him.
More leads immediately moved the bottleneck into delivery
The initial constraint was client acquisition. Once the campaign worked, the firm encountered a very different problem. Brock says the team could onboard only three or four clients a month while roughly ten opportunities were arriving. He was more concerned about serving those clients well than keeping the ads running, so he turned the campaign off while he rebuilt capacity.
Peter recalls the campaign adding about $10K in monthly recurring revenue. That increase was enough to require another accountant, yet Brock did not feel ready with hiring practices, standard operating procedures, or project management. This is where Peter connects Brock’s language—the path of most resistance—to the theory of constraints. A firm is a pipeline from attention and sales through delivery, reviews, and retention. Opening one narrow point does not widen the whole system.
Brock also changed the economics around onboarding. He had not been charging a meaningful onboarding fee, which limited both near-term earnings and the ability to finance further acquisition. He began treating the start of the relationship as a distinct stage that required its own capacity and structure.
Specialized roles made onboarding and recurring work easier to repeat
The revised delivery path gave one person responsibility for onboarding. When that work was complete, Brock or the CFO held a post-onboarding meeting to explain what had been done and ask for a review at the point when the client could see the result. The account then moved to an accountant dedicated to recurring bookkeeping.
That handoff was easier to explain because each person had a clear job. The onboarding lead was excellent at setting up the relationship; the next accountant focused on accounting every day. The separation also reduced dependence on a single team member because the client had already worked with more than one person inside the firm.
Standardization made hiring easier as well. Brock says every client used the same profit-and-loss structure. Monthly bookkeeping lived in repeatable projects, reconciliations followed the same basic path, and the reporting metrics generated consistently. A new accountant still needed accounting knowledge and judgment, but did not have to rediscover how every client engagement worked.
Accounting support expanded the experienced team’s capacity
Brock divides the work conceptually into the large share of repeatable bookkeeping tasks and the smaller share of unusual problems that require stronger judgment. In his model, a staff accountant reached a capacity point at around 40 clients. The firm then paired that person with an overseas accountant who could perform a meaningful portion of the repeatable work while the US-based accountant remained client-facing.
The boundary was not simply easy work versus hard work. Brock kept sensitive actions, including transfers between client bank accounts, with the US-based accountant because of cybersecurity concerns. He describes the support relationship as a way to make the client-facing bookkeeper more efficient, estimating a 50% to 70% improvement in capacity rather than replacing the role.
He is candid about hesitating before hiring overseas and about dismissing people who did not meet the firm’s accountability standards, whether domestic or overseas. Within roughly three months, the firm had three support team members. Brock also emphasizes that they are skilled people with families and communities, not interchangeable software. The operating lesson is focused division of labor, not indiscriminate outsourcing.
A narrow niche improved the deliverable, not just the positioning
ProMover Accounting’s focus began through a partner who owned a moving company and believed Brock’s reporting could help the industry. That relationship supplied market access and operating context Brock would not have had by applying an industry label on his own. Over time, the firm narrowed further by asking which clients received the most value in the least delivery time.
Repeated work with moving companies let the firm build a service that would be difficult to provide across unrelated industries. Brock describes learning through advisory calls. When an owner asked how much cash to hold before the slower winter season, he combined the expected seasonal burn with a minimum current-ratio threshold and turned the answer into a repeatable recommended minimum cash balance. Once the formula was useful, it became part of the recurring bookkeeping report.
The same focus supported Brock’s next offer: a group advisory model for moving-company owners. Comparable financial statements could be normalized and reviewed across businesses, while owners in different territories could share operational knowledge without competing locally. Peter’s point is that this depth is possible because the businesses are similar enough for the comparisons and advice to mean something.
The funnel used the language moving-company owners already used
Peter then walks through the campaign itself. The first page offered a training specifically for local moving-company owners and collected a name and email before revealing the video. That gave the firm a way to continue helping people who showed interest but were not ready to book a call on the first visit.
The training translated the vague instruction to know your numbers into three questions an owner could understand. It did not lead with detailed accounting terminology. The page made the next step available during the video and supported the promise with multiple video testimonials from moving-company clients. Peter describes this combination as a simple message in the buyer’s language plus visible evidence that the firm had done the work for similar businesses.
An application then collected the company, website, location, and revenue information. Prospects below $500K in annual revenue were not sent to the calendar. Besides protecting Brock’s sales time, that choice prevented the campaign from teaching Meta that every form completion represented the kind of customer the firm wanted.
The time after booking became part of the sales process
For qualified prospects, the calendar kept the next available conversation close. Peter recommends a three- to four-day booking window when possible because a cold prospect can lose momentum during a long delay. The more important change came after the booking: the confirmation experience did not stop at a generic appointment-received message.
Brock’s page asked the prospect to confirm the appointment, collected information about the current accounting setup to prepare accurate pricing, and showed a roughly ten-minute walkthrough of the reports the client would receive. Follow-up emails repeated the deliverable video and linked to case studies. The material gave prospects room to research the firm after raising their hand, when their questions and attention were more concrete.
Brock says his sales calls had often lasted an hour because bookkeeping is an intimate service involving financial records and bank access. The deliverable walkthrough meant he no longer had to spend the call selling every part of the work. Prospects could arrive with a clearer picture and use the conversation for questions, cutting the calls roughly in half in his experience.
Paid acquisition had to be judged against value and capacity
The campaign ran on Meta because moving-company owners, like most audiences, could be found across Facebook and Instagram. Peter and Brock recall beginning around $5K to $6K in monthly spend and later reducing it to roughly $3K. Neither presents the platform as an instant exchange of one dollar for two. Brock says a firm should expect to spend during the learning period while the system finds responsive people and the team improves the message.
When an attendee asks about customer acquisition cost, Peter says he does not have the exact figure for Brock’s campaign. He gives a broad range from other client campaigns but returns to the more important calculation: acquisition cost only makes sense beside price, margin, retention, and payback. Brock’s bookkeeping started at $549 a month, and he points to long client relationships to explain why the firm could responsibly spend more to acquire a customer than a business selling a one-time service.
That logic still depends on delivery. The firm cannot treat a long potential lifetime value as permission to buy leads it cannot onboard or serve. Brock’s story closes the loop established at the beginning: marketing, sales, and fulfillment form one system. Growth came from opening the current constraint, watching where pressure moved, and building the next piece before turning the volume back up.
