Consider First-Class Package Services:  First-Class Package Service (FCPS) continues to be positioned as a lightweight (less than 1 lb.) offering primarily used by businesses for fulfillment purposes.  FCPS allows you to send packages weighing less than 1 lb. and save 32% or more vs. Priority Mail.

Multi-carrier shipping:  Our SendPro solutions reduce the complexity of USPS shipping and automatically give you access to Commercial pricing discounts.  And whenever you need, it’s simple to use UPS and FedEx – from our single solution – to help ensure you don’t overspend on shipping.  Multi-carrier rate shopping from a single platform like SendPro empowers your business to make smarter decisions on how you ship to maximize savings.

DIM Weighting:  Your packaging matters.  Lighter weight, lower density packages are comparatively less profitable for carriers because they take up so much space relative to the price charged per package (based on weight alone). Looking for ways to adjust this model, carriers started using dimensional (DIM) weight rates. DIM weight rates allow carriers like the USPS to establish a minimum charge for the cubic space a package occupies. DIM weight is calculated by multiplying the length by width by height of each package (in inches) divided by carrier divisor for shipments.  The current divisor for USPS is 194, but that will change to 166 on June 23, 2019.
