Aloha
I do not ship often but occasionally need to send things to the Mainland from Hawaii.
I have always used XPS in the past. Must I have a shipping app or pay a fee to ship via Square online? It makes life easier . However since I rarely ship I'd rather not pay for something I do not use often.
HI, all plans on the Square platform have USPS and DHL connected.
