Plumber CRM Automation Case Study

Client Background

PipePro Plumbing (name changed for privacy) is an 8-truck residential plumbing company based in Pinellas County, Florida. The company handles everything from routine drain cleaning and water heater replacement to full repipes and bathroom renovations. Annual revenue at the time of engagement was approximately $1.8 million, with the owner aiming to break $2.5 million within 12 months.

The owner started as a sole proprietor 6 years ago and grew through aggressive Google Ads spending and strong word-of-mouth. The marketing side worked. Leads came in. But the back office never kept pace with front-line demand. The CRM (Housecall Pro) was being used primarily as a scheduling tool. The estimate follow-up, review generation, and referral programs were all supposed to happen manually. In practice, they did not happen at all.

The company had a capable office manager who genuinely tried to do everything. But she was a single point of failure across dispatch, invoicing, customer service, AND sales follow-up. When the choice was between answering a ringing phone and following up on a 3-day-old estimate, the phone won every time. The estimates died in silence.

The Challenge

The company had a CRM full of dead leads. The owner knew follow-up was the issue but could not afford a full-time salesperson. Estimates went out and then sat in email inboxes with no follow-up. The close rate on estimates over $2,000 was just 22%, well below the industry average of 35-40%.

The office manager was handling dispatch, invoicing, AND sales follow-up. Something always fell through the cracks. On busy days, estimates were not sent until the next morning. Follow-up calls happened sporadically at best. When they did happen, the office manager often could not remember the details of the job without digging through notes.

The company sent an average of 45 estimates per month for jobs over $2,000. At a 22% close rate, they were closing 10 jobs. But the owner believed that with proper follow-up, that number should be 18-20. The gap between 10 and 18 closed jobs at an average ticket of $3,200 was $25,600/month in unrealized revenue.

They had tried hiring a part-time follow-up coordinator ($1,500/month), but the coordinator had no system, no scripts, and no way to track what had been sent. After 3 months, the close rate had only improved by 2 percentage points, and the coordinator left for another job. The owner was back to square one.

The Solution

TightSlice built an end-to-end CRM automation pipeline using n8n and GoHighLevel. The system was designed to handle every step from estimate delivery through close, with zero manual intervention required for the standard follow-up sequence.

When a technician completed a diagnostic, they entered the estimate details into a mobile form (built as a simple web app). The estimate was generated from a branded template and sent to the customer within 5 minutes via text and email. No more waiting until the next morning for the office manager to type it up.

An automated follow-up sequence triggered immediately: Day 1 email with estimate details, company credentials, and a relevant before/after photo from a similar job. Day 3 text message check-in asking if they had questions, with direct reply enabled. Day 7 call from the AI voice agent that could answer common objections and offer to schedule the work. Day 10 email with a testimonial from a customer who had similar work done. Day 14 final follow-up with a limited-time 5% discount for scheduling within 48 hours.

Every interaction was tracked in the CRM with full context. When the office manager did make personal follow-up calls, she had complete visibility into every touchpoint: what emails were opened, what links were clicked, and whether the customer had responded to any previous outreach. She could see at a glance which estimates were hot and which were cold.

The system also automated review requests after completed jobs (2-hour delay, then SMS with direct Google review link) and referral requests at the 60-day mark (email with referral incentive). Post-job follow-up required zero staff time.

Implementation took 5 weeks including a custom mobile form for technicians. Total setup cost was $5,800 with a $750/month management fee.

The Results

Close rate on estimates over $2,000 jumped from 22% to 62% within 90 days. Monthly revenue increased by $18,000 within the first quarter. The office manager reclaimed 25 hours per week that had been spent on manual follow-up, estimate generation, and review requests.

The automated referral program generated 8 new customers in the first quarter with zero ad spend. Each referred customer had a higher-than-average ticket size ($4,200 vs. $3,200) and a 90% close rate, consistent with industry data showing that referred leads close at 2-3x the rate of cold leads.

Google reviews increased from 2-3 per month to 12-15 per month. The company's Google rating improved from 4.2 to 4.7 stars within 4 months, which the owner credited with increasing inbound call volume by approximately 20%. The review request automation alone generated an estimated $8,000/month in additional revenue through improved search visibility and conversion rates.

After 6 months, the company added a 9th truck and hired two additional technicians, funded entirely by the revenue increase from automation. The owner's total investment (setup + 6 months of management) was $10,300. The total additional revenue generated was $108,000+. The company crossed $2.4 million in annualized revenue in month 8, putting them on track to exceed the $2.5 million goal ahead of schedule.

"I knew we were leaving money on the table with bad follow-up. I just did not realize it was $18,000 a month. The automation does what I always wanted a salesperson to do, except it never forgets and it works 24/7. I used to stress about follow-up every night. Now I just check the dashboard and see everything running. Best money I have ever spent on my business."
