This guide walks you through creating a new product in TREX - as a single listing or in bulk if you're creating multiple SKUs at once.

Category, Variant Group Code, Offer SKU and Customer Type cannot be changed once created. Delete and recreate the product to fix any of these.

Edit Product

Go to Products → My Products. Find the product — search under All Products, Pending, or Changes Required, or use the filters.
Click the product name → go to the tab with the field you want to edit → click the pen icon → edit the field.

Click Save & Proceed to Unique Attributes → Category Attributes tab → Submit.

Bulk Edit Products

Go to Products → My Products → check the box for each product you want to edit → click Bulk Manage.
Select the attribute type to edit — General Attributes, Category Specific Attributes, or Price & Stock Attributes — then click Export File.
Edit the relevant fields in the exported file and save it.
In TREX, go to Upload Excel File → drop your file in Uploaded Templates → click Upload New Template.
Go to Products → My Products → Bulk Upload of Multiple Products, and check the status:
- green tick means it uploaded successfully, an exclamation mark means there are errors.
- If there are errors, click Download Error Report → scroll to the Failed Reason column to see what's wrong, e.g. a missing Delivery Type. Fix the flagged field in your file, then repeat the step to re-upload.

Once submitted, the Seller Centre team reviews the product for approval. Standard SLA is 1–2 business days.

No issues → status moves from New to Approved, and the product goes live.
Issues found → status moves from New to Changes Required, with a rejection reason provided. Fix the flagged field(s) and resubmit — see Product Information Guide if you need to check requirements again.

Why hidden/deleted products still appear on the storefront?

Hidden via Availability End Date — Takes effect almost immediately. If it's still showing on the Product Display Page after a few minutes, contact us via the Merchant Service Desk (via Okta SSO).

Deleted products — Removed from the Product Display Page within 24 hours.

Why is my product out-of-stock (OOS) when inventory is available?

This usually comes down to one of two causes:

Out of Stock Quantity matches Stock Quantity — In TREX, check whether Out of Stock Quantity = Stock Quantity. If so, clear that field so Out of Stock Quantity reads 0 instead.
Products stuck in customers' shopping bags — If Out of Stock Quantity is already 0, the product may be showing as OOS because customers have added it to their bag without checking out therefore reserving stock that doesn't sell. This is resolved automatically once a scheduled cronjob is run to release those unpurchased items. If it is still showing as OOS after 15-30minutes, please let us know via the Merchant Service Desk (via Okta SSO) so that we can look into it.

How to hide products?

Go to Products → Add New Products → Bulk Upload of Multiple Products → drop your file in the Uploaded Templates section → click Upload New Template.
