Event-Based Business Custom Development Custom Payments Recurring Billing

Dynamic pricing and
installments, engineered
into GoHighLevel forms.

An event-based business with variable, selection-based pricing needed payments handled inside GoHighLevel forms - but the native payment elements couldn’t calculate dynamic pricing or prevent manipulation. We engineered a custom scripted payment engine with secure backend pricing and automated installments.

Event-Based Business.

The client was an event-based business offering programs with variable pricing - the cost depended on selections like the number of participants.

They wanted to handle payments through GoHighLevel forms, with a system that could automatically calculate pricing, prevent manipulation, and support installment-based payments - all while keeping checkout smooth enough to maximize conversions.

The problem: GoHighLevel’s native payment elements simply couldn’t do dynamic, selection-based pricing - and a naive workaround would leave pricing exposed to manipulation.

What was broken.

The compounding operational gaps that made the status quo unsustainable.

01
Limited native GHL functionality.
GoHighLevel’s default payment elements couldn’t dynamically calculate pricing based on user selections.
02
Pricing manipulation risk.
Without a controlled system, users could potentially alter payment values - a direct revenue-loss risk.
03
Manual payment follow-ups.
Installment payments required manual tracking and follow-up, adding ongoing operational workload.
04
Conversion drop-offs.
A complicated or unclear payment process was reducing the number of completed registrations.
05
Variable pricing logic.
Pricing that changes based on participant count and options needed real calculation logic, not a static price field.

What we built.

We engineered a custom payment system inside GoHighLevel forms, combining advanced scripting with automation. A dynamic pricing engine calculates totals from user inputs, all calculation happens securely on the backend to block manipulation, the engine connects natively to GoHighLevel’s payment element, and installment plans run on automated recurring billing.

01

Custom scripted payment engine.

Developed a dynamic pricing system that automatically calculates totals based on user inputs such as the number of children or selected options.

02

Secure pricing logic.

Bypassing native limitations, the script calculates pricing on the backend - preventing users from manipulating payment amounts.

03

Integrated collect-payment element.

Connected the dynamic pricing engine directly to GoHighLevel’s payment element for a smooth, native-feeling checkout experience.

04

Automated installment plans.

Enabled recurring billing so customers can pay in structured installments without any manual intervention from the client’s team.

05

End-to-end payment automation.

Once a user selects a plan, the system automatically handles all future payments - eliminating follow-ups and reminders entirely.

What changed.

Measurable outcomes after deployment.
