Common questions
Which carriers can I use?
UniUni, Purolator, UPS and FedEx, for parcels shipped within Canada. One account covers all four, and every quote shows the services each one offers on your route. Canada Post is coming soon.
Do I need a thermal printer?
No. Every label comes as a 4 × 6 PDF for thermal printers and as a letter-size PDF you can print on any printer, cut out and tape on.
What happens if a carrier re-measures my parcel?
We post an adjustment with the carrier's reason and email you. When the carrier reports its weight and size, they show next to yours. We charge the saved card three days later. Dispute it before then and the charge waits while we look into it.
Can I cancel a label?
Yes. Void any label the carrier hasn't scanned within 28 days of buying it, and the full amount, tax included, goes back to the card you paid with.
Can you ship to PO boxes?
Not yet. Canada Post, which delivers to PO boxes and general delivery, is coming soon. UniUni, Purolator, UPS and FedEx deliver to street addresses only.
How is sales tax charged?
GST, HST or QST is added at checkout, based on the province the parcel ships from, and shown on every receipt.
