For most stores, ThemeHigh’s Checkout Field Editor is a top pick because it lets you add, edit, remove, hide, and reorder WooCommerce checkout fields, plus set validations and control where fields display. If you want powerful conditional logic and easy drag-and-drop field ordering, WP Desk’s Flexible Checkout Fields is another excellent choice, with a strong free version and a feature-rich Pro upgrade. If you need a straightforward editor for billing and shipping fields with conditional rules, QuadLayers’ WooCommerce Checkout Manager is also popular. Note: WooCommerce’s official Checkout Field Editor extension is for the legacy checkout, not blocks, in many stores.

The “best” booking plugin depends on your needs. For service businesses that want an all-in-one system with a modern booking form, staff scheduling, reminders, and events, Amelia is a strong choice. For a widely used appointment plugin that’s highly configurable and supports options like Google Calendar integration and WooCommerce compatibility, Bookly is a popular pick. If you want something simple, quick to set up, and free to start, Simply Schedule Appointments works well for consultants and small teams. For rentals or store-style bookings, consider WooCommerce Bookings add-on too.

A common example is a T-shirt sold in different sizes and colors. You create one product called “Classic T-Shirt.” Then you add attributes like Size (S, M, L, XL) and Color (Black, White, Blue). WooCommerce generates variations like “M / Black” or “XL / White.” Each variation can have its own price and stock, like XL costing more and having fewer units. The product page shows dropdowns for size and color, and the buyer selects their preferred option before adding to cart. This is exactly how variable products are used.

A simple product is one item with one price and one set of details. It has no selectable options like size or color. You can still set inventory, shipping, and sale price, but there are no variations. A variable product has attributes and multiple variations. Each variation can have a different price, stock, SKU, weight, and image. Customers must choose options before adding to cart. Simple products are easier to set up and best for single items. Variable products take more setup time, but they are best for products with multiple options under one listing.

A variable product in WooCommerce is a single product that offers multiple variations based on attributes like size, color, material, or style. Each variation can have its own price, SKU, stock quantity, image, and shipping details. Customers choose the options on the product page using dropdowns, and WooCommerce adds the selected variation to the cart. Variable products are best when you sell the same item in different options, but you want to manage it under one product page. This keeps your store clean and helps buyers compare choices easily without browsing multiple separate products.
