Connecting with USPS

First, navigate to Settings > Channel Management > Shipping Channels, then select the drop-down list on the top right of the page to find and select the USPS option, then click the Add button:

USPS will then be immediately enabled on your ChannelGrabber account.

Purchasing USPS Label Credits

This works a little differently to our other couriers, in that you purchase label credit from ChannelGrabber, and then for each label you generate in our system we pay USPS for you.

To get started, click on the Purchase $100 credit button and we will bill you $100 and then deduct the appropriate amount for each label you create in ChannelGrabber:

You can either keep this topped up manually whenever your credit runs low, or you can set the Auto Top-Up toggle to ON, which will automatically purchase $100 of USPS credits as soon as your balance drops below $100 in ChannelGrabber.  This will ensure that you never experience any interruptions to your USPS label processing in ChannelGrabber:

Your remaining balance is shown above the toggle and you will find invoices for your USPS credit purchases further down the same page, so make sure to download these for your accounting as regularly as you require.

To access this page again in future, simple navigate to Settings > Channel Management > Shipping Channels and click the Manage button on your USPS courier profile:


Creating & Printing Labels

Important Note:  All courier labels generated in ChannelGrabber will be 6x4" (150x100mm) which is the universal standard size, so you need to ensure that your labels are the correct dimensions.

To get started, please navigate to your main Orders page:

1.  Select as many orders as you need using the check-box to the left of each order, or select all orders by clicking into the top check-box:


2.  Click the Ship button from your actions toolbar:


3.  Review Orders
If you have previously set up Shipping Aliases, then the courier and service should be automatically pre-selected based on the shipping method from the order channel, and will display a "Ready" message:

If you have not set up a Shipping Alias for one or more of the services, then you will see an "Input Required" message and will need to select the courier and then the service you want to use, then click the Continue button on the top right corner of the page:


4.  Finalise Label Details

At the top left corner of the page you will be able to see how much label credit you have remaining, and can click the Top Up button if you need to add more credit:

You can now enter the weight (in kg) for each item (if you have already entered weights on previous orders or on the Products page, then these will be pre-filled in based on the SKU of the items ordered).

After the weight, you can set additional details for each order, such as the Dimensions and Package Type ( you can ignore the Item(s) per Parcel field for USPS - this is only present in ChannelGrabber for certain other couriers):

Once you have selected all necessary options, you need to click the Fetch Rates button, which will then show you the cost of each label before you create the labels.  You can do this per order at the end of each row, or you can click the Fetch All Rates button at the top right corner to collect them all at once:

Once we have collected the rates for every order, they will be displayed in the Cost field for each order, and the total cost for all labels will be displayed at the top right corner:


You can then either click the individual Purchase Label buttons next to each order if you want to generate the labels separately, or you can click the Purchase All Labels button to generate all the labels at once:

This will generate labels for each of your orders, so once you see the Print Label button appear next to each order, that shows that the label is ready to print.  As before, you can either print labels individually or use the Print All Labels button to create a PDF file containing all the labels so they can be printed as one big batch:

Once you have generated your label PDF files, simply print them on your label printer, and then you're done, or alternatively, if you want to have your USPS labels incorporated onto an integrated label invoice, don't click Print here, but instead, once the labels have been created, simply return to your Orders page and generate the invoice and if you have set your invoice design to include a courier label (see guide on Personalising Your Invoice Design) the label will automatically be added to the invoice layout for you to print altogether.


ChannelGrabber Tip:  If you would like to be able to easily check which orders have had their shipping labels created from the main Orders page, you can enable the Shipping Label Created Date column on your order table (see our guide on How to Customise the Order Page for more detail on this), which will then display the time and date that your label was created next to the order for easy reference:


Generating a USPS Manifest in ChannelGrabber

When you're all done with your USPS labels for the day, you can then complete the full process by generating the manifest in ChannelGrabber.  

All you need to do to trigger the manifest is click the drop-down arrow next to the Ship button on the main Orders page and click the Manifests button, then selecting USPS and clicking the Generate button:

You only need to do this once a day, after you have finished creating all the labels you need for that day, then you can print the manifest ready to hand over with your USPS parcels to your collection driver.
