I want to integrate shipping with my UPS Account, not use Shippo

[ShadeDot]

I do not want to print labels through Shippo.  I want to use my own UPS.com business shipping account.  Otherwise, my UPS shipping discounts will be revoked due to too low a shipping volume.  This means that, into the future, I will only be able to get affordable shipping rates when I ship through Shippo on the website-- I won't be able to ship any products or do any business outside the website because retail shipping costs will destroy my modest profit margin. I can't allow this to ransack my other business sales.  HOW can I integrate directly with my own UPS.com account and never use Shippo.  Can someone help me?  Thank you.  PS - If you're a small business, think about what I said.
