# Requirements - Rateline 1.x documentation

> The WordPress, WooCommerce and PHP versions Rateline needs, and the checkouts and store setups it works with.

- **WordPress** 6.5 or later (tested up to 7.1)
- **WooCommerce** 8.2 or later (tested up to 11.1), active; WordPress won't activate Rateline without it
- **PHP** 7.4 or later

## What it works with

- **Shipping zones.** Table rate is a zone shipping method like WooCommerce's Flat rate and Free shipping. Add it to any zone, as often as you like, each time with its own table.
- **The Cart and Checkout blocks and the classic cart and checkout.** Rateline gives WooCommerce its rates; WooCommerce shows them wherever it shows shipping options, including the shipping calculator.
- **High-Performance Order Storage (HPOS).** Rateline doesn't read or write orders and declares itself compatible.
- **Taxes.** Each method is taxable or not, like WooCommerce's own methods. If your store shows prices with tax, the subtotal in your rules includes tax too.
- **Shipping classes.** Your own classes, set on products under **Product data → Shipping**.

## What the rules read from your products

- **Weight**: each product's weight (in the unit under **WooCommerce → Settings → Products → General**), times its quantity, added up.
- **Number of items**: the quantities in the cart, added up.
- **Subtotal**: the line totals after coupons, as your customers see them.
- **Shipping class**: each product's class.

Only items that need shipping count. Virtual and downloadable-only products are left out of the weight, number of items and subtotal.

## Nothing else to set up

Rateline adds no database tables, scheduled tasks or external requests. Each Table rate method's settings, rules included, are one WordPress option.
