Yes. The new V5 desktop version allows you to use your company's own UPS account to check rates, create shipping labels, and schedule pickups. The rates are the prices your company negotiated with UPS, and UPS bills your company directly. Patisco does not handle shipping fees.
You need to prepare two things: 1. A UPS account (Shipper Number, 6 digits). If you don't have one, apply at the UPS website—company accounts are typically activated the same day. 2. Go to "ADMINISTRATION → Company Profile Settings → Third-party Integrations → UPS Integration Settings" and click "Link UPS Account". Log in with your UPS credentials, authorize, and enter your 6-digit account number.
Once linked, the "Shipping Method / Express" section at the bottom of the packing slip page and the "Express Shipment" button in the Shipping Management list will let you use UPS directly.
