This would also be extremely useful, quite shocked to find that it isn’t currently possible.
Our existing Magento store that we’re migrating from has over 27,000 individual rules, generated from a custom google Docs spreadsheet containing info sent by the shipping companies (usually in extremely unhelpful formats that can’t be automated), that are set up to calculate pricing using two shipping companies and offers fine-grained control over different countries and regions and product types, along with an automated script that we can use to see how the prices are applied to a selection of preset typical carts. This would obviously be unfeasible to replicate+update manually in Shopify.
Compiling these price rates is already a big undertaking for several staff members, with lots of potential for error even with our currently semi-automatic-import workflow. One of the big draws of Shopify was that tasks like this would require less time and involvement from multiple staff members, but from reading this it seems that it might actually be worse!
Considerable work and training has also gone into this semi-automated system and so I’m not thrilled that this may need to be thrown away – a simple CSV import/export feature, or even an API, would save us many many hours during setup and going forward.
As best I can tell, moving to Shopify will require us to pay extra monthly fees for multiple integrated shipping rates apps to get accurate quotes – or to devise a shipping price structure that could see us either taking losses on shipping for big parcels to difficult destinations, or losing sales by overcharging for smaller parcels.
Especially with COVID, we are finding that shipping rates are changing frequently and are getting increasingly specific as different countries/regions face different difficulties – receiving multiple ad-hoc notifications of eg ‘5% increase on all shipping in country Z from region B’.
Hope there’s some news on this soon. Our store is 3dt-subscriptions.myshopify.com.
