ProtonShip vs Stallion Express
Checked against stallion.ca on
Short answer. Stallion is built for online sellers, especially those shipping to the US, with branches and drop-off points and a mix of national and regional carriers, paid from prepaid credits. ProtonShip ships within Canada only and charges each label to your card. Both let you dispute carrier adjustments after the fact; Stallion deducts them from your credits automatically, while ProtonShip shows you the carrier's figures and waits before charging.

How each handles carrier adjustments
When a carrier re-measures a parcel or corrects an address, it bills more. The platform that sold the label decides how that reaches you.
“When an adjustment is applied, it is deducted automatically from your wallet balance.”Stallion help centre, postage adjustments and fees
Stallion Express: Adjustments typically appear 7 to 21 days after delivery and are deducted automatically from your credits, with a line in your transaction history. You can dispute one in your account within 45 days of the charge, with photos. A notice before the deduction isn't stated.
ProtonShip: the adjustment is posted with the carrier’s reason, and its figures next to yours when it reports them, and nothing is charged for 72 hours; a dispute holds the charge. How adjustments work, and why we show the carrier’s numbers first.
Who Stallion Express suits better
Online sellers who ship a lot to the US, sellers near a Stallion branch or drop-off point, Amazon FBA shippers, and anyone who wants same-day delivery around Toronto.
Who ProtonShip suits
Businesses shipping parcels within Canada who want four carriers in one account, paid per label by card. ProtonShip doesn’t ship to the United States or overseas, carry pallets, or run drop-off branches. The detail is on pricing, carrier adjustments and coverage and claims.
Switching from Stallion Express
Stallion's help centre puts an Export button on its Shipments, Orders, Products, Returns and Transactions pages, and a shipment export downloads as a CSV file. Custom export formats let you choose the fields that go in it. The help centre doesn't list those fields, so check the file against our template's columns before you upload it.
Stallion keeps box presets in its settings, and they aren't among the exports it lists, so note their sizes and save them as boxes in ProtonShip. Parcels to the US or overseas, and Amazon FBA shipments, stay with Stallion: ProtonShip ships within Canada only.
ProtonShip’s bulk upload takes a CSV or Excel (.xlsx) file of up to 500 parcels. The first row needs the template’s column names, with to_name, to_street1, to_city, to_province, to_postal_code and weight_lb required, and columns it doesn’t use are ignored. A box column can name a saved box, and a from_address column a saved ship-from address, row by row. How bulk labels work
