How does label printing and manifesting work?

MyPost Business shipments can be processed in the same way as any other courier on Starshipit.

If you're paying for MyPost Business labels by credit card you don't need to manifest your MyPost Business shipments once the labels have been printed. All charges are applied to your credit / debit card as soon as you print your labels.

If you're using a MyPost Business charge account this will be charged each time your labels are printed.

What size labels does MyPost support?

There are two label sizes available for domestic. They are:

  • 100x150mm (A6)
  • Four A6 labels on an A4 sheet

For international there is one size:

  • CN23 (A5) labels printed on A4 paper.

When and how are charges applied?

Credit Card / Debit Card

Each time you print a MyPost Business label in Starshipit your credit card will be charged by Australia Post. Each time you print this will be reflected as one transaction on your card.

So if you print one label at a time you will have multiple transactions shown on your bank statement. If you bulk print the charges will be consolidated under one transaction.

Charge Account

Each time you print a MyPost Business label in Starshipit the amount will be added to your MyPost Business charge account. Payments can then be made to your MyPost Business account outside of Starshipit.

To set this up follow the below steps:

  1. Navigate to the MyPost courier settings in Starshipit: Settings > Couriers > MyPost Business Settings
  2. Click the Lookup button next to the Account Number field
  3. Click the Select button next to the row with the Account Type "Charge"
  4. Click Save

How can I cancel a shipment and get refunded?

Note: Only payments made by credit / debit card can be refunded online. MyPost Business charge account customers must contact Australia Post Customer Service to request a refund.

MyPost Business shipments must be cancelled from your account within the MyPost Business portal.

To do this follow the below steps:

  1. Log into the MyPost business dashboard.
  2. Click the Track tab at the top of the screen.
  3. Find the shipment you would like to cancel, then click View to the right of it.
  4. Click the Refund button will be displayed in the top right.

Note: If a shipment is ineligible to be refunded, the Refund button will not be displayed. To view a list of reasons why a shipment is ineligible, refer to the MyPost Business FAQs which can be accessed via the Support section in the MyPost Dashboard.

How do pickups work?

Pickups can be booked in through Starshipit when you bulk print labels with MyPost Business. To enable the pickup functionality follow the below steps:

  1. In Starshipit, go to Settings > Couriers > MyPost Business.
  2. Tick Book pickups on bulk label print
  3. Click Save.

When you book a pickup through Starshipit via bulk print the pickup will be created for the next business day between 9am and 1pm.

Each time you bulk print a pickup is created, so be sure to print all of your labels under one bulk print each day, as Australia Post charges $11.98 per pickup.


What is the difference between the MyPost Service Codes

MyPost Business has two different service types. Flat Rate Satchels/Boxes and their Parcel services. In general, if you are buying the branded boxes and satchels from Australia Post you should be using the flat rate boxes, and if you are using your own packaging you should be using the parcel services. For more information, please contact Australia Post. 

B20 and B30 vs B21 and B31

You will notice that there are two different parcel post services and two different express post services. 

  • B20 is Express Post for orders under 5kg.
  • B30 is Standard Post for orders under 5kg.
  • B21 is Express Post for orders between 5kg and a maximum weight of 22kg
  • B31 is Standard Post for orders between 5kg and a maximum weight of 22kg

Starshipit will automatically display the service that matches the package dimensions in the order dialog. This is the same with live rates.
