## Inbox Module
When a new inbox order is received, the **Inbox** status tab at the bottom of the GTX window will turn orange and display the number of unprocessed items.
The Inbox module can be opened by:
* Double-clicking the **Inbox** status tab
* Selecting **Main > Enquiries > Inbox** from the menu bar
### Invoicing Inbox Orders
The **Inbox** module will open showing a list of unprocessed supplier messages.
**To process an inbox order:**
* **Double-click** the inbox message
The order will open in the **Purchases** module with supplier details and invoice information pre-filled.
**Review the order details:**
* Check **quantities**, **costs** and **tax**
* Match any **[unmatched products](/gtx/docs/supplier-inbox-ob#unmatched-products)**, if required
:::(Info) (Note)
All invoice details can be edited except the **Total Invoice Amount** and **GST**.
:::
Once reviewed, the order can be **finalised** using the Purchases module as usual.
## Unmatched Products

If a product cannot be matched, **red question marks** will appear in the Product column.
**To match a product:**
* Click the **{{glossary.Magnifying Glass}}** picker in the Product column
* **Select** the correct product from the list
* If no match exists, click **Add a New Match**
In the **New Match for an External Code** window:
