Do you sell beyond Shopify?
If yes, a multi-platform shipping tool such as Starshipit, Shippit or ShipStation covers more ground. OrderOps is Shopify only, on purpose: that is what makes the two-way sync and the multi-store queue possible.
Do you hold your own carrier contracts?
If you have an Australia Post eParcel or StarTrack contract, OrderOps ships on it with no markup and no per-booking fee. If you do not, a marketplace model can get you moving sooner.
Is shipping the whole problem, or the last step?
If your day is also picking from racks, packing at a bench, printing labels and keeping stock honest across stores, OrderOps replaces several tools rather than one, at one price with no add-ons.
