How to get things setup in ShipperHQ
The first thing you’re going to want to do is define the Zones in ShipperHQ. You’ll want to get in contact with stamps.com to get these zones. Once you’ve gotten these zones defined; you’ll want to enter those into ShipperHQ
Define boxes in ShipperHQ
USPS Cubic pricing adheres to certain boxes that have a cubic feet range from .01-.50. Meaning, that you’ll need to break all of your boxes down to cubic feet to see which boxes are applicable for Cubic Pricing. I’ll put my box list below.
–Box A is a 5x5x5. So figuring in the USPS Cubic Pricing this equals 5 x 5 x 5 / 1728 = .07 Cubic Feet. This means that depending on my zone, my rate will come from the 0.1 column.
–Box B is a 6x6x6. So figuring in the USPS Cubic Pricing this equals 6 x 6 x 6 / 1728 = .125 Cubic Feet. This means that depending on my zone, my rate will come from the 0.2 column.
–Box C is a 8x8x8. So figuring in the USPS Cubic Pricing this equals 8 x 8 x 8 / 1728 = .296 Cubic Feet. This means that depending on my zone, my rate will come from the 0.3 column.
–Box D is a 9x9x9. So figuring in the USPS Cubic Pricing this equals 9 x 9 x 9 / 1728 = .421 Cubic Feet. This means that depending on my zone, my rate will come from the 0.4 column.
**PLEASE NOTE, if a box goes over .50 Cubic Feet; the item is not eligible for Cubic Pricing**
