Stamps.com now has a USPS shipping module for X-Cart that will allow you to print pre-paid USPS postage for all of your X-Cart orders. This feature is available at no additional cost for Stamps.com customers.
To implement the integration, simply follow the instructions found
here. Please note that this integration requires an active Stamps.com account and the latest version of the Stamps.com software (software updates are free for Stamps.com customers).
Please be aware that during the initial integration it may take a few hours for your first batch of orders to import to Stamps.com. This delay is normal. Please do not attempt to reconfigure the X-Cart integration in Stamps.com while you are waiting for the initial batch to import as this may cause additional delays with the integration.
If you have any questions or feedback, please be sure to let us know so that we can help make this integration as useful as possible for the X-Cart community. Thanks!
