Hi,

Check in the settings of the specific POS if you have typed "limit categories" with a default value that your products don't have.

1️⃣ Check POS Category vs. Product Category

• POS uses “Point of Sale Category” (pos.category_id), not the regular Inventory/Product Category (categ_id).
• Make sure the product’s POS Category is actually set to “Plumbing,” not just the regular product category.
  • In Sales > Products > Your Product > Point of Sale tab — check “POS Category.”

2️⃣ Availability in POS

• In Point of Sale > Products, make sure:
  • “Available in Point of Sale” is checked.
  • If you have multiple POS sessions/shops, confirm it’s assigned to the correct POS.

3️⃣ Archiving or Published State

• If the product is archived, it will still be searchable but not listed in category view.
• If using website & POS sync, check that “Published” is on (some setups hide unpublished products from POS category browsing).

4️⃣ Product Type & Stock Settings

• If your POS is set to hide out-of-stock items, and the product has zero stock in the POS warehouse, it won’t appear unless searched.
  • Check Inventory > Reports > Product Quantities for that item.

5️⃣ POS Cache Refresh

• POS loads products into browser memory at session start. If you just added or changed the category, restart the POS session to refresh the product list.

test: Assign the product temporarily to another POS category, refresh POS, and see if it appears — if yes, the original category may have a hidden filter or hierarchy issue.

Hi I still cannot solve this problem even with the response below, can someone help me?

Hi,

1. Enable "Available in POS" – Go to Sales → Products → Point of Sale tab and check if it's enabled.
2. Check POS Category – Ensure the product is linked to the correct POS category under Point of Sale → Configuration → Product Categories.
3. Restart POS Session – Stop and restart the POS session to reload product data.
4. Unarchive Product – Ensure the product is not archived under Sales → Products.
5. Verify Multi-Company & User Access – If using multi-company, ensure the product belongs to the correct company and user has access.

If the issue persists, try clearing the POS cache (Ctrl + Shift + R) or check the browser console for errors. 

Hope it helps
