WooCommerce Product Add-Ons Point of Sale (POS) Integration

FooSales for WooCommmerce fully integrates with the WooCommerce Product Add-Ons extension so you can capture and manage customizable product options directly at the POS. If you’ve configured add-ons on your WooCommerce products (global or per-product), those same options are surfaced in the FooSales Point of Sale (POS) when adding items to the cart and completing orders. This keeps in-person orders consistent with your online store.

How the WooCommerce Product Add-Ons plugin works

↑ Back to top

WooCommerce Product Add-Ons lets you attach extra fields (e.g., dropdowns, checkboxes, short/long text) to products, either globally by category or individually per product. You can use these fields to collect choices like sizes, toppings, gift messages, and more, and optionally set pricing per option. Add-ons are stored with the line item so they appear consistently in carts, orders, and exports. For full details, see the official guide: https://woocommerce.com/document/product-add-ons/

Requirements

↑ Back to top

• FooSales Plus plan or active 7-day free trial. The FooSales for WooCommerce license purchased via WooCommerce.com (Marketplace) does not include access to third-party integrations (e.g., WooCommerce Product Add-Ons, FooEvents, Stripe etc). To use these integrations, purchase a FooSales Plus plan (or start a 7-day free trial) and link it to your domain.
• FooSales for WooCommerce plugin version 1.41+.
• WooCommerce Product Add-Ons plugin installed and active on your site.

How the integration works

↑ Back to top

Add-ons in FooSales behave the same as in WooCommerce:

• When a product with add-ons is added to the cart in FooSales, its options appear in the Product Tools Panel.
• Staff can select and (on the web app) adjust those options before checkout.
• For online orders, FooSales displays the exact selections so staff have everything needed for fulfillment. This is ideal for restaurants and takeout operations, especially when used with order alerts.

Where add-ons appear in FooSales

↑ Back to top

Product Tools Panel (web app):

View and modify add-ons for items already in the cart.

Order list:

Add-on selections are shown under each order’s items in the FooSales order list.

Receipts:

Add-ons print on receipts, giving staff and customers a clear, itemized record—useful for kitchens and assembly lines.

Importing and exporting add-ons (JSON)

↑ Back to top

WooCommerce Product Add-Ons supports importing/exporting global add-on groups as JSON. This is useful for migrating configurations or bulk setup.

Export: Products → Add-Ons → open a global add-on group → Export to JSON.
Import: Products → Add-Ons → Import a JSON file to create/update a global add-on group.
Test in FooSales: Add a relevant product to the cart in the FooSales web app and confirm options appear and calculate as expected.

For more, see Importing and Exporting Add-Ons in the official guide: https://woocommerce.com/document/product-add-ons/
