I just realized I may not be able to use Shopify as I'm using a single carrier, UPS. We have negotiated rates with them that are significantly reduced. Is there a way to add these to my store. Is this not available?
How do I use these rates? It's definitely a make or break for me using Shopify, as shipping rates are critical to my business.
You can avail the live shipping rates feature using for an additional $20/month and then use your UPS account to get negotiated rates in the system. Alternatively, if you do not want to pay extra you can switch to the yearly plan instead of the monthly plan. In that case, you don't need to pay anything extra. If you are also planning to use your own account to generate labels with those negotiated rates, you can use the Multi carrier shipping label app for this purpose.
