Two Systems Serving the Same Customer โ Never Speaking to Each Other
ShopLaunch is a marketing agency specializing in the PDR (Paintless Dent Repair) niche, running GoHighLevel-powered marketing systems for over 20 active shop locations across the US. Their clients use GHL for lead capture, pipeline management, and automated follow-up. In the field, those same shops rely on MobileTech Rx (MTRX) โ a purpose-built mobile estimating and invoicing app โ to create estimates, approve vehicles, write work orders, and send invoices.
These two systems served the same customers at different stages of the job โ but they had never talked to each other. ShopLaunch's clients were running their marketing operation and their field operation as two completely separate businesses. Every time a deal moved forward in the field, someone had to manually update GoHighLevel. With 20+ locations processing multiple jobs per day, that was hundreds of manual pipeline touches per week.
A Promise Made to 20+ Clients. Months Without Delivery.
ShopLaunch had committed to delivering a working MTRXโGHL integration to their entire client network. The problem: MobileTech Rx had no open API โ only a one-way Zapier integration. Every build attempt hit the same walls.
- Hundreds of manual pipeline touches per week. Every estimate, work order, payment, and review trigger required someone to manually open GHL and drag the contact to the next stage. Across 20+ locations, that was unsustainable.
- No open API on MobileTech Rx. MTRX only exposed a one-way Zapier integration, making bidirectional contact sync extremely difficult to architect โ and every third-party GHL connector produced incomplete results.
- GHL custom objects in early beta. The Vehicle and Estimate object architecture in GoHighLevel had known bugs and undocumented behavior โ every static integration approach risked silent breakage when either platform shipped a patch.
- No documentation existed for the MTRX Zapier app. What was actually buildable had never been mapped. ShopLaunch's team had attempted the build and hit repeated dead ends. No one had fully audited the platform's triggers and actions.
- Client churn risk was real. At least one location couldn't use their GHL account for over a month. Refunds were being issued. The longer the integration stalled, the more the client relationships were at risk.
ShopLaunch had made a promise to 20+ clients that the system would work. Every week without automation was another week of manual pipeline drag, missed review requests, and clients questioning whether they'd been sold something that didn't exist. The integration had to ship โ or the client relationships were at risk.
A 7-Zap Integration Architecture โ Full Job Lifecycle, Zero Manual Touches
We designed and built a 7-Zap integration architecture that fully connected MobileTech Rx and GoHighLevel for every PDR shop location on ShopLaunch's network. Each client account gets a deployed set of Zaps that automate the entire job lifecycle โ from first estimate to final review request โ with no manual pipeline management required.
Error alerting across all Zaps: Every failure surfaces as a Slack notification to ShopLaunch's team in real time โ no silent errors, no clients discovering issues before the team does.
From Undocumented Platform to Production-Grade System
Discovery โ Auditing an Undocumented Platform
Audited the MTRX Zapier app from scratch with no existing documentation. Identified all available triggers and actions, their data payloads, and the exact limits of what was buildable without MTRX developer involvement. Confirmed the platform had no open API โ Zapier was the only integration surface.
Architecture & Gap Analysis
Mapped the full client journey from estimate through invoice across both platforms. Identified which automations were immediately buildable, which required GHL custom objects (Vehicle, Estimate), and which needed feature requests submitted directly to the MTRX development team.
Bug Reporting & Dev Collaboration
MTRX was in active development. We documented and submitted bug reports as issues were discovered โ including field renaming across versions, contact ID format changes in the v1.028 patch, and broken custom object associations in GHL's early beta. This kept the build unblocked while fixes were staged by both platform teams.
Build & Sandbox Testing
Designed the full 7-Zap architecture per account and built the integration in a sandbox environment (Athens dev account) before any live deployment. Implemented Zapier filters to handle race conditions and propagation delays between MTRX event triggers and GHL record availability.
Phased Live Rollout
Deployed first to pilot accounts (Dent Spa, Dent Rehab, Dentless Touch) with close monitoring. Identified edge cases in production โ duplicate opportunity creation, contact data timing gaps โ and resolved each before scaling to the full 20+ location network.
Documentation, SOPs & Knowledge Transfer
Created Loom walkthroughs, written SOPs, and a reusable account setup process. Took over all new client onboarding across the ShopLaunch network during the rollout, then transitioned full operational ownership to ShopLaunch's new support manager in March 2026 with complete documentation handoff.
Before vs. After
The Takeaway
20+ PDR shop locations now run a fully automated job lifecycle โ from first estimate to final review request โ without a single manual pipeline touch. ShopLaunch delivered on the promise they made to their clients. The integration that had stalled for months shipped, scaled across the network, and was handed off with full documentation. What started as a one-way Zapier connection with no documentation became a production-grade, bidirectional system now powering the core of ShopLaunch's client value proposition.

Zap 1 & 2
Bidirectional Contact Sync
New MTRX contacts flow into GHL. Qualified GHL contacts push back into MTRX. Deduplication logic and data validation filters prevent sync loops and ghost records on both sides.
Zap 3
Estimate Created โ GHL Opportunity
An estimate created in MTRX triggers a new Opportunity in GHL's Active Sales pipeline automatically โ no manual stage creation.
Zap 4
Vehicle Approval โ GHL Custom Object
Vehicle approval in MTRX creates a custom Vehicle object in GHL, associates it to the contact, and advances the pipeline stage automatically.
Zap 5
Work Order Created โ Customer Notification
Work order creation fires a "vehicle in shop" message to the customer via GHL workflow โ keeping them informed without anyone on the team acting.
Zap 6
Work Order Closed โ Ready for Pickup
"Ready for pickup" notification fires automatically when the work order is marked closed in MTRX โ no manual send.
Zap 7
Invoice Paid โ Review Request
Invoice paid in MTRX triggers the GHL review request automation โ closing the customer journey loop and capturing reviews that were previously never sent.
Error alerting across all Zaps: Every failure surfaces as a Slack notification to ShopLaunch's team in real time โ no silent errors, no clients discovering issues before the team does.
