Checkout Blocks Field Studio

Build custom WooCommerce checkout fields, conditional logic, and fee rules for Classic checkout and Checkout Blocks from one admin UI.

Checkout Blocks Field Studio gives merchants a reliable checkout field builder for the modern WooCommerce ecosystem. Create field groups, add custom inputs, control when fields appear, validate submitted values, apply fees or discounts, and keep everything synced to orders, emails, and admin workflows without maintaining custom snippets.

Why Store Owners Choose It

One builder for two checkout surfaces: target Classic, Blocks, or both from the same configuration.
Built for real stores: collect VAT numbers, PO references, gift messages, delivery notes, business-only details, and service add-ons.
Revenue-friendly: attach fixed or percentage fee rules for upsells, handling charges, and checkout discounts.
Operations-ready: save values to order meta, show them in WooCommerce admin orders, and include them in order emails.
Safer rollouts: use JSON import/export, backups, preflight diagnostics, debug logs, and safe mode when troubleshooting.

Important Blocks note: WooCommerce Checkout Blocks currently exposes native support for text, select, and checkbox fields only. Unsupported types are mapped to the closest available Blocks input while server-side validation and order saving remain intact. Billing and shipping scoped fields also map to the shared Blocks address area. These are current WooCommerce Blocks API limitations, not plugin-specific bugs.
