Liftoff supports multiple shipping methods via USPS, UPS, and FedEx, as well as supporting the ability to define custom shipping methods. By default, options for USPS and UPS methods of shipment display published rates utilizing the shipment aggregator EasyPost. Linking to your own EasyPost account will not only display contracted shipment rates, but will also enable the option to display FedEx rates. To link your EasyPost account, view the information for Settings below.


Heavy Packages

Shipping rates exceeding 150lbs require custom shipping options. These shipments are considered "hundred-weight" and can be calculated by speaking to an account representative for that shipping method and may possibly be available on their website.

For more information, see our article on heavy shipments.

ShipStation integration is also available. Please see Shipstation integration for more info.


EasyPost Questions?

Launchpad is unable to assist you with setting up or managing your EasyPost account. If you have questions regarding the setup and management of an EasyPost account, please visit them directly.


When you are at the Shipping Options portion of your navigation, you will be presented with two tabs. To add a new shipping method, look under the Methods tab.

Some common issues can typically be resolved by checking these three things:

  1. Double-check your product setup (is there a weight?)
  2. Double-check your carrier setup (does your carrier method support the weight of the products?)
  3. Double-check your vendor setup (do you have an accurate address for your vendor?)

If you still need additional troubleshooting help, please reach out to your account manager.


On the Methods tab, you can add, modify, or delete your shipping methods.

Add shipping methods

To add a new shipping method, click the + Add Shipping Method button.

  • Method - Select your desired shipment method from the dropdown box.
  • Display Name - If selecting a Custom method, enter the name of the method (i.e., Ground 150+).

Any other methods will have the name automatically entered, but you're welcome to edit them if you desire.

Once you have selected your method and defined your name, click the Save button.


The settings tab controls any settings that affect all shipping methods.

  • Auto-Fulfillment - Electing to flag a shipment as auto-fulfilled will deduct the quantity from the on-hand inventory as soon as the order is submitted, instead of when the order is shipped. Selecting this option will display a message to the customer that an order has been submitted. Please note: For pending orders, the quantity deduction and status change do not take effect until after the order is fully approved.
  • Attention Field - You can elect to require a value for the "Attention" field for shipping addresses during checkout.
  • Allow Residential - If checked, customers will be provided an option to mark their shipping address as residential. Please note that Liftoff does not verify addresses as residential or commercial.
  • Shipping Calculations - By checking this option, you can elect not to calculate or display shipping and handling charges on your site at all.
  • Shipping Estimator - Checking this option removes the "Estimate Shipping" button and the two fields above it ("Select country..." and "Enter ZIP...") from the cart page on your site.
  • Shipment Weight Threshold - See below.
  • Order-Level Handling Charges - This is where you can supply a flat rate that gets added to the shipping cost for every order, regardless of shipping method.
  • Carrier Rates - You can choose between using retail rates, published rates, or negotiated rates, if available. See below for more information about these types of rates.
  • EasyPost API Key - This is where you enter your EasyPost API Key to link your EasyPost account with Liftoff.

Modifying shipping methods

If you need to edit one of your shipping methods, such as to define an amount for a custom method, click the Edit button. This will open 2 tabs.


All USPS, UPS and FedEx shipments are rated automatically. However, if you wish to set your own shipping costs or add a rate for a custom shipping method, click the + Add Rate button.

  • Weight-based - If you are setting your shipping rate based on weight, you can define the weight range here. Leaving this field blank will impose no minimum or maximum.
  • Price-based - If you are setting your shipping rate based on total product price, you can define the price range here. Leaving this field blank will impose no minimum or maximum.
  • Rate Amount - This is where you set the cost. It is a required field.
  • Omit Handling - You can elect to omit any product handling fees if this rate is in effect.
  • Fallback Rate - This rate will be offered only if carrier rates are not available (i.e. in the unlikely event that EasyPost is down, carrier rates aren't available for that delivery location, etc.)
  • Description - This is an optional description of what message you would like displayed to your customer when this rate is in effect.


  • Display Name - You can change the name of your shipping method here.
  • Markup - You can choose to mark up this specific shipping method by a fixed rate or a percentage.

Shipping Method Settings

All other settings are for informational use only and cannot be modified.

If you need to delete a shipping method at any time, simply click the Delete button.

Carrier rate selection

  • Negotiated Rates – These are your account-specific rates provided to you by a carrier if you have an agreement in place. These rates require the presence of an EasyPost API key. Typically, these rates are heavily discounted and only used in special circumstances.
  • Published Rates – UPS and FedEx offer this as a middle tier between retail and negotiated rates. This is the typical rate you’ll receive if you log in to the carrier’s website and request a rate using your account number, but with negotiated rates omitted. This is the rate selection used by most suppliers when quoting competitive freight costs.
  • Retail Rates – The retail rate is the highest amount you can expect to pay for a given carrier’s service. This is the standard rate you would receive if you were dropping a package off at a UPS or FedEx location for shipment, and should be the default rate presented to you if quoting a shipment on your carrier’s website.


Did you know?

With Liftoff's intelligent shipping feature, only shipping methods that are applicable to an order will be displayed (i.e., orders exceeding 12oz will not have an option for USPS First Class).

Advance ship notes (ASN)

You can configure Liftoff to trigger an email notification when shipping information (or a change in shipping status) is entered for an order. To begin, navigate to Ecommerce > Shipping > Settings tab.


Tick this box to turn changes in shipping status into email notification triggers.

Once that box is ticked, the trigger is set. It will fire when the shipping status for an order changes to "Shipped" or a value is entered in the "Actual Ship Date" or "Tracking Number" fields. You (or another admin) can make these changes manually by navigating to Orders > Orders > Details button > Shipments tab.

Note that any shipping status changes made via an order integration will trigger the notification, too!


Changing the dropdown to "Shipped" or providing an Actual Ship Date or Tracking Number will fire off a notification email, telling the customer about the update automatically.

Weight threshold


Remember, this setting is independent of any maximum a carrier may allow.

This field allows you to set a maximum weight for any given parcel shipped by this account site. For example, if you need parcels never to exceed 57 pounds, set this value to 57.

Note that this field is not connected to carrier requirements for any shipment carrier method you've specified in Ecommerce > Shipping. Most standard shipping methods from the major carriers come with a maximum parcel weight of 150lbs; if you set the Threshold field above to a value greater than 150 and haven't specified a shipping method that allows for such heavyweight shipments, Liftoff may generate an error for the customer when they attempt checkout. It is up to you to provide Liftoff with a custom shipping method which will accommodate the threshold you specify.

During checkout, when a value is set for Shipment Weight Threshold, Liftoff will attempt to create combinations of products in such a way that the least possible number of shipments are created. As an illustration of this, consider the following scenario:

Customer's cart contains the following products:

  • Three 100lb items
  • Three 50lb items
  • Three 20lb items
  • Three 10lb items
  • Three 5lb items
  • Three 1lb items

Assuming the Shipment Weight Threshold field has been set with a value of 150, Liftoff will generate the following shipments:

  • Shipment A: 1 x 100lb item, 1 x 50lb item
  • Shipment B: 1 x 100lb item, 1 x 50lb item
  • Shipment C: 1 x 100lb item, 1 x 50lb item
  • Shipment D: (everything else!)


Product attributes are not considered

When Liftoff generates shipments as illustrated above, it does not consider product dimensions, bundled items, or any other attribute of the products in the cart. If there are requirements for certain products shipping (or not shipping) together in the same parcel, you'll need to consider those before choosing to leverage the Shipment Weight Threshold field.
