# Requirements - Wholesaleline 1.x documentation

> What Wholesaleline needs to run, where it keeps its data, and what it works alongside.

## Server and WordPress

| | Minimum |
|---|---|
| WordPress | 6.5 |
| PHP | 7.4 (8.1 or later recommended) |
| WooCommerce | 8.2 |

## Where Wholesaleline keeps its data

Wholesaleline adds no database tables. It keeps:

- its settings and customer groups as WordPress options;
- each group as a user role ("Trade", say), which customers get next to their own role, so the **Users** screen can list and filter them;
- each customer's own prices, tax setting, payment terms and application on their user account;
- each product's group prices and quantities on the product;
- each order's payment terms, due date and payment on the order.

On multisite, every site has its own groups, settings, customer settings and applications.

## Works alongside

- **The Checkout block and the classic checkout**: group prices, quantity rules, the minimum order, payment and shipping methods, tax exemption and **Pay on account** work in both. So do the Cart block and the classic cart.
- **High-Performance Order Storage (HPOS)**: supported, as is the older posts storage.
- **Block themes and classic themes**: prices, quantity boxes and hidden prices show in WooCommerce's own templates and blocks, including the product blocks that load their data from the Store API.
- **Other Extendiment plugins**: Discountline rules can target wholesale customers, Gridline edits group prices in bulk, and Labelline, Optionline and Swatchline Pro respect hidden prices. See [Other Extendiment plugins](other-plugins).
- **Page caching**: Wholesaleline tells page caching plugins not to cache pages that show a customer's own prices.
