Visual drag-and-drop payment form builder with live settings.

Turn any WordPress page into a high-converting payment or donation form in 2 minutes.

If you sell a single product, accept donations, send client invoices, or charge event booking fees, you don’t need a heavy online store. You just need a fast, dependable payment form.

GatewayKit is the payment form and donation builder for WordPress: create custom checkout forms, accept donations, or connect Elementor forms to secure payment processors. No WooCommerce, no shopping cart, no 2%–3% platform fees, and no e-commerce bloat.

Set up in minutes using our visual drag-and-drop form builder, native Gutenberg block, or shortcodes. Every payment is tracked in a centralized WordPress dashboard, and professional PDF receipts and tax invoices are emailed to your customers automatically.

Who it’s for: Freelancers, consultants, small businesses, nonprofits, course creators, event organizers, and web agencies building client sites.

Translations: Available in English, Spanish, French, German, Brazilian Portuguese, and Arabic.

Requirements: WordPress 6.2+, PHP 7.4+. Works with any WordPress theme. Gutenberg and Elementor compatible. No WooCommerce required.

External Services

This plugin connects to payment provider APIs to process payments.

What is sent and when

When a user submits a payment form, the plugin sends the payment amount, currency, and a transaction reference to the configured payment provider’s servers for authorization and capture. No personal user data beyond what the provider requires for payment processing is transmitted.
