Our GoHighLevel Services
1. GoHighLevel Marketplace App Development
Turn your product into a one-click installable app on the GoHighLevel Marketplace. We build, package, and ship marketplace-ready applications that pass GHL's review standards and install in minutes — no custom dev required per agency.
Scope includes
- OAuth 2.0 install flow and secure token management

- Multi-tenant architecture with isolated, per-location data
- Custom values, webhooks, and event handling
- Versioning, update flows, and post-launch maintenance
- Marketplace submission support through to approval
2. Custom Conversation Provider Development
Bring any messaging or calling channel natively into the GoHighLevel conversations tab. We build custom Conversation Providers so SMS, iMessage, WhatsApp, voice, and third-party messaging flow directly inside GHL — no tab-switching, no broken context.
Scope includes
- Native inbound and outbound message sync into GHL conversations
- SMS, MMS, voice, iMessage, and third-party channel integration
- Delivery status, threading, and contact mapping
- Webhook and API wiring to your messaging backend (Twilio, ElevenLabs, custom)

3. Custom Payment Provider Development
Let your clients collect payments through their own gateway directly inside GoHighLevel. We build custom Payment Providers that connect your processor to GHL invoices, order forms, subscriptions, and checkout — fully branded and compliant.
Scope includes
- Custom payment gateway integration into GHL's payment flows

4. Custom Actions & Triggers App
Extend GoHighLevel workflows with your own automation building blocks. We develop custom Actions and Triggers that let agencies plug your product directly into the GHL workflow builder — firing events and executing logic without code.

- Custom workflow Triggers (e.g. "Estimate Created", "Lead Scored")
- Custom Actions that call your API or run business logic
- Dynamic input/output fields mapped to GHL contact and opportunity data
- Conditional logic, data transformation, and error handling
- Marketplace packaging so any agency can install and use them
- Documentation for non-technical workflow builders
5. Custom GoHighLevel API Integration with Third-Party Platforms
Connect GoHighLevel to the rest of your stack. We build bi-directional integrations between GHL and CRMs, billing tools, data sources, and SaaS platforms — keeping contacts, opportunities, and events in sync in real time.
Scope includes
- Bi-directional data sync (contacts, opportunities, calendars, custom objects)
- Integration with platforms like Airtable, Pipedrive, Google Sheets, Stripe, HubSpot, and custom APIs
- Real-time webhook and event-driven architecture
- Field mapping, deduplication, and conflict resolution
- Rate-limit handling, retries, and monitoring
- Headless / API-first GHL architectures
6. Custom Dashboards Design
Replace fragmented reporting with one clear view. We design and build custom dashboards that pull GoHighLevel and third-party data into a single, real-time interface for agencies, clients, and internal teams.
Scope includes
- Unified marketing, sales, and operations dashboards
- Real-time data aggregation from GHL and external platforms
- Custom KPIs, charts, filters, and date-range reporting
- White-labeled, client-facing reporting views
- Role-based access and multi-location rollups
- Embedded or standalone (headless GHL frontend) builds
7. Custom GoHighLevel White-Label Theme Customization
Make GoHighLevel truly your own. We customize the GHL interface and white-label experience so your platform looks and feels like your brand — from login to dashboard to client portal.
Scope includes
- Custom CSS / theme styling across the GHL UI
- Branded login, color schemes, fonts, and layout adjustments
- Custom menu links, dashboards, and embedded tools
