Compatible Plugins
WCPOS saves POS sales through the WooCommerce REST API, so most WooCommerce plugins work with them without any extra setup. A few need WCPOS to step in, because they only act on the online checkout or the WP Admin order screen, and a few can't be used with the POS at all. This page covers four of them and what you do for each.
Product Bundles, Composite Products and Product Add-Ons are on the Roadmap for 2.3.
Plugins that don't work with the POS
Deactivate wePOS before you use WCPOS. Stripe Tax doesn't work with POS orders: for automated tax at the till, use WooCommerce Tax.
wePOS
What you do: in WP Admin > Plugins, find wePOS and select Deactivate, then find WCPOS – Point of Sale for WooCommerce and select Activate. If you can't open Plugins, ask your store administrator to do it. While wePOS is active, WCPOS turns itself off the next time WP Admin loads and shows: WCPOS cannot run alongside the wePOS plugin due to compatibility issues. WCPOS has been deactivated.
Why: wePOS changes how your store sends variable products, which breaks variations in the POS.
Stripe Tax
What you do: for automated tax on POS orders, use WooCommerce Tax. It is the automated-tax plugin WCPOS supports.
Why: Stripe Tax doesn't work with POS orders, and there is no workaround.
Plugins WCPOS works with
WooCommerce Tax
What you do: follow the WooCommerce Tax setup steps to turn on automated taxes. The POS copies your WooCommerce tax settings each time it loads your store, so there's nothing to change in the POS.
How WCPOS handles WooCommerce Tax
WooCommerce Tax looks up rates from your online checkout and the WP Admin order screen, and POS orders reach your store another way. So WCPOS asks WooCommerce Tax for rates each time an open POS order saves, and POS sales get the same rates as your online orders.
Yoast SEO
What you do: nothing.
How WCPOS handles Yoast SEO
WCPOS leaves Yoast's SEO data out of what the POS downloads, so syncs stay light. It also keeps the link the apps use to find your store, even if Yoast is set to remove it.
Integrations and extensions
Installing extensions needs WCPOS Pro. The free version shows the extension directory with its install buttons turned off.
If a plugin you use has a WCPOS extension, set it up from Extensions.
What's the difference between an integration and an extension?
An integration is a plugin you already run for your online store. WCPOS works with it without an add-on, and steps in where it needs to, as it does for WooCommerce Tax. An extension is an add-on built for WCPOS, such as a card terminal, or an add-on that lets WCPOS work with a translation plugin such as WPML.
Something not working?
If a plugin you rely on misbehaves with the POS, start with Plugin Conflicts. It lists the known conflicts and how to find a new one.
