We’ve all been there: The order is packed, the box is sealed, and then it comes time to ship (which means logging into carrier portals, hunting for the best rates, and finally tracking down that shipping label).

To reduce unnecessary complexity out of your day-to-day, we’ve built carrier integrations right into the heart of CartonCloud — so you can streamline your shipping process without ever needing to switch systems.

TL;DR: In our latest CartonCloud Unboxed Webinar, I walk you through how we’ve brought carrier connections, rate selection, and label printing into one seamless workflow to help your team pack and ship without friction.

A new way to manage carrier integrations

We’ve introduced the ability to connect to a wide range of carriers directly within CartonCloud — over 150 globally — without needing to pay for external platforms.

Now, you can:

  • View live rates
  • Select carriers
  • Print labels
  • Send tracking updates

All from within your existing workflow!

How carrier integrations are structured in CartonCloud

To give you flexibility across regions and use cases, we’ve built three integration pathways.

1. Shippit (Australia & New Zealand)

Shippit provides strong carrier coverage across AU/NZ, with 50+ integrations available.

Inside CartonCloud, you can:

  • Access Shippit with no subscription
  • Use pre-negotiated rates or your own accounts
  • Manage carriers, bookings, and returns from one place

This also opens up the opportunity to reduce freight costs by leveraging pre-negotiated rates where it makes sense.

2. EasyPost (North America & global)

For North America and international shipping, EasyPost provides broad coverage across major carriers.

With EasyPost, you can:

  • Connect your own carrier accounts
  • Access pre-negotiated rates
  • Set everything up directly from within CartonCloud

The setup is designed to be fast — with accounts created and connected automatically.

3. Direct carrier connections

For key carriers, we’ve also built direct integrations — including Australia Post and USPS.

This ensures you can still use your own accounts where aggregator limitations exist, giving you full control over how you ship.

Setting up your carrier integrations

Carrier integrations can be configured in two ways:

  1. Organisation-level
  • Shared across all customers
  • Ideal for standardised operations
  1. Customer-level
  • Unique to individual clients
  • Perfect for 3PLs managing multiple carrier contracts

You can also combine both — giving you visibility across all available rates and the flexibility to choose the best option.

How it works in the Pack Screen

Once everything is connected, the real value shows up in your day-to-day workflow.

As soon as an order is packed:

  • CartonCloud automatically requests rates from all connected carriers
  • Only valid options are returned (based on size, weight, location)
  • The system can automatically select the best option

For example:

  • Small parcels → postal carriers
  • Larger items → freight carriers
  • Different regions → different carrier sets

Automating carrier selection with rules

You can take this a step further by setting up carrier selection rules.

These can be as simple or as detailed as you need:

  • Always choose the cheapest rate
  • Prioritise fastest delivery
  • Use specific carriers for certain customers
  • Route shipments based on location

This removes decision-making from the packing bench and ensures consistency across your operation.

From packing to dispatch in one step

Once a rate is selected:

  • The order is packed
  • The shipment is booked
  • Labels are generated instantly
  • Tracking is created and linked

That tracking information is then pushed back to connected systems — including customer storefronts — so everyone stays informed without additional admin.

FAQs

Q1: Can I connect my existing carrier or aggregator accounts?

A: Yes, you can connect your own carrier accounts, as well as use aggregator platforms like Shippit and EasyPost. Some custom setups may require assistance from our team.

Q2: Do I need the Transport Management System (TMS) to use this?

A: No, carrier integrations are available without the transport module. You only need warehouse fulfilment enabled.

Q3: Will tracking information update back to customer storefronts?

A: Yes, tracking details are automatically passed back to connected storefronts once the shipment is created.

Q4: Can I set up integrations per customer?

A: Yes, integrations can be configured at both organisation and customer level, depending on how your operation is structured.

Q5: Are integrations billed per connection?

A: Yes, each integration connection is billed individually, similar to other integrations in CartonCloud.

Q6: Can non-3PL businesses use this?

A: Yes, this functionality is available for both 3PLs and in-house logistics teams.
