Custom WooCommerce plugin that splits a single purchase into two independent payments while preserving native order workflows.
Overview
Designed and developed a custom WooCommerce plugin that allows a single purchase to be divided into two independent payments.
Instead of attempting to charge one order twice, the plugin creates a parent order and two related child orders that each follow WooCommerce’s standard checkout and payment flow. This architecture maintains compatibility with WooCommerce while supporting real-world purchasing scenarios where one person can pay with two different methods or two people or departments share the cost of an order.
The project includes a complete administrative interface, automated order synchronization, customer payment workflows, compatibility with both Classic and Block Checkout, and a dedicated beta testing portal used to recruit testers, manage support requests, and gather feedback prior to public release.
Result
- Created a maintainable split payment solution using native WooCommerce order architecture instead of modifying payment gateway internals.
- Preserved compatibility with standard WooCommerce payment methods and checkout experiences.
- Simplified long-term maintenance by relying on native WooCommerce order lifecycle events rather than custom payment processing.
- Beta testing website to support documentation, tester recruitment, feedback collection, and ongoing product refinement.
