Cahoot technology rate shops across all of the services you select here and then automatically creates the best shipping label accordingly, so make sure your selection at this step is accurate. For example, many merchants aren't aware that USPS Regional Rate Boxes can often save quite a bit of money compared to Priority Mail. If you stock this carrier-supplied packaging, make sure to indicate that you can support it, and Cahoot will use it when it saves you money to do so.
1. Go to Settings > Supported Carrier Services, and select the shipping services you support for each carrier by checking the box next to each service.
2. Connect your carrier accounts to Cahoot by using the Credentials tab. You only need to enter the top four fields. Validate the connection using the Test Rate Calculation button on the bottom of the page and then click Save.
