The starting point.
Golden State Trailers builds custom car-haulers, equipment trailers and mobile workshops out of a Sacramento facility. The product is genuinely customisable, every trailer has 30+ decisions a buyer makes (chassis, deck length, axle count, ramp type, tie-down configuration, paint, lighting). The brand is strong, the manufacturing is excellent, and the funnel was the bottleneck.
A great product, an analog funnel
The dealer network sold the way founders had sold for fifteen years: a buyer would call, the sales rep would walk through options on paper, sketch a configuration, manually price it, email a PDF quote, and wait. A single quote took two to three days from first call to signed proposal.
The team capped at roughly 8 quotes per week per rep. Every additional dealer added linear cost. The metric that mattered, time-to-quote, was a function of how many people were holding pencils.
- 2-3 day average quote turnaround
- 8 quotes/week ceiling per sales rep
- No central pricing logic, every quote was bespoke
- Dealer follow-up scattered across email, SMS and voicemail
- Zero attribution between marketing spend and closed deals

A WebGL configurator wired into the CRM
We rebuilt the buying experience around a real-time configurator that mirrors the manufacturing constraints. Every option a dealer or buyer toggles updates the 3D model and the price simultaneously. When a configuration is locked, a PDF quote is generated server-side and a lead is pushed to HubSpot with the full configuration JSON attached.
The dealer side got a portal with saved configurations, customer history, and a re-quote button that respects the original spec. Sales reps stopped writing quotes and started reviewing them.

What the work returned.
Measured at the 90-day post-launch mark and verified by the client team.
What we'd do differently next time.
We underweighted the dealer training program. The configurator is intuitive for a buyer but for a dealer who used to walk customers through paper, the UX needed three rounds of in-person sessions before adoption stuck. Build the training program in week 1, not week 12.
Live pricing turned into the marketing message we did not predict. Dealers started sharing configuration links from their phones during meetings, and the brand became “the trailer company that prices on the spot”. Sometimes the operating change is the campaign.
In their words.
“They built a system that runs the business while we sleep. Six months in, we are doing twice the revenue with the same team.”
