Gravity Forms Custom Development & Integration

Custom add-ons, API integrations triggered by form submission, complex multi-step workflows, and calculator forms — for WordPress sites with serious form requirements.

Gravity Forms Development

Gravity Forms is the most powerful form plugin in the WordPress ecosystem — and with custom development, it becomes a complete data collection, processing, and routing platform. We build custom add-ons that extend Gravity Forms with new field types, feed integrations, and workflow automations beyond what the standard add-ons offer.

Custom Gravity Forms Add-on Development

We build fully-featured Gravity Forms add-ons using the official Add-On Framework — the same foundation used by official Gravity Forms add-ons. This gives full access to the Gravity Forms API: feed processing, field settings, admin UI integration, and reliable hook points.

  • Custom feed add-ons that process form submissions and route data to external systems
  • Custom field types with bespoke UI and validation logic
  • Admin settings panels following Gravity Forms UI conventions
  • Conditional feed logic — only trigger integrations when the form meets defined criteria
  • Custom notification logic and templating beyond standard GF notifications

Multi-Step Complex Form Workflows

Forms that span multiple pages, branch based on user input, and collect different data depending on earlier answers — built with Gravity Forms conditional logic, page breaks, and custom JavaScript where needed.

  • Multi-page forms with progress indicators
  • Conditional page branching based on field values
  • Dynamic field population from earlier answers
  • Save and continue functionality for long forms
  • Custom validation logic at each step before proceeding
  • Custom confirmation pages and conditional redirects

API Integrations Triggered by Form Submission

On form submission, route data to any external system with an API — CRMs, ERPs, project management tools, communication platforms, or custom business systems.

Systems We Connect To

  • CRM platforms (HubSpot, Salesforce, Pipedrive, Mautic)
  • ERP and business management systems
  • Slack and team communication tools
  • Email marketing platforms
  • Custom webhooks and REST APIs
  • Zapier and n8n automation platforms

What Gets Sent

  • Full form submission data mapped to API fields
  • File uploads forwarded to destination systems
  • Conditional data — only send relevant fields per entry
  • Transformed data (calculations, lookups, formatting)
  • Error handling and retry logic for failed API calls

Calculator & Quoting Forms

Real-time pricing calculators, ROI tools, and quote builders built on Gravity Forms — using formula fields, conditional logic, and custom JavaScript for complex calculation requirements.

  • Dynamic price calculators with real-time total updates
  • ROI and cost-benefit calculators for B2B sales tools
  • Multi-variable quote builders with configuration steps
  • PDF quote generation from form submissions
  • Email quote delivery with itemised breakdowns

WooCommerce Product Configuration via Gravity Forms

Using the Gravity Forms Product Add-ons extension or custom integration, we build product configuration wizards that capture complex requirements at the product or cart level — with custom pricing formulas, conditional fields, and configuration data stored against the WooCommerce order.

  • Complex product configuration forms embedded on WooCommerce product pages
  • Configuration data stored with the order line item
  • Custom pricing formulas driven by configuration choices
  • Admin order view showing full configuration details

Have a Complex Form Requirement?

Describe what you need your forms to do. We’ll outline whether it’s achievable with Gravity Forms configuration, custom add-on development, or a hybrid approach.
