# Supplier Inbox

****Marlin GTX**** enables direct processing of electronic supplier orders using the inbox.

The inbox receives electronic supplier orders **directly into GTX** and imports them into the Purchases module for processing.

When a new inbox order is received, the **inbox** status tab at the bottom of the GTX window will turn orange and the number of outstanding orders will be shown in brackets.

Double-click the **Inbox** tab to open the Inbox module.

Tip

Direct inbox ordering can be set up for Megabus's many supplier partners including **Burson**, **Repco**, **Bridgestone**, **Continental**, **Michelin**, **Pirelli**, **Yokahama** and more.

To set up electronic ordering for these or any other available suppliers, please [contact the Megabus Support Team](https://www.megabus.com.au/support)

Note

The **Inbox** can also be accessed by selecting **Main > Enquiries > Inbox** from the menu bar.

## Invoicing Inbox Orders

The **Inbox** module will open, showing a list of unprocessed inbox orders:

- **Double-Click** on a message to open it

Note

Inbox orders can be **invoices** or **credits**.

The order will open in the **Purchases** module, with the **Supplier**, **Invoice Number** and other details already filled in.

**Double-check** the order details:

- Select any [unmatched products](/gtx/docs/supplier-inbox#unmatched-products), if required

Note

All of the invoice details can be edited, if necessary, except for the **Total invoice** and **GST** amounts.

The order can then be **[finalised](https://help.megabus.com.au/gtx/docs/purchase-invoices#invoicing-purchases)**, as usual.

### Unmatched Products

Most products on inbox orders will be **automatically matched** with those in your GTX system.

If a product is not recognised, it will show a series of **red question marks** and needs to be matched manually.

**To match the product:**

- Click on the **{{glossary.Magnifying Glass}}** picker in the Product column
- The **External Code Matches** pop-up will open, showing a list of possible matches

If present, select the **correct match** from the Possible Matches list.

Alternatively, click on the **Add a New Match** button at the bottom right, if none are appropriate.

The **New Match for an External Code** pop-up will open:

- Select a **Product Code** to match with
  - To automatically match the same product with that code in future, click **Remember Match**
  - To only match this time, click **Match Once**

Note

**New products cannot be added from this module.** If an appropriate product does not exist, you will need to [add it using Product Maintenance](https://help.megabus.com.au/gtx/docs/products-maintenance#adding-products), before you can match it in the Supplier Inbox.
