Is there any rationale in using

Spree::Store

to distinguish between sales channels like a POS, or a 3rd party such as Amazon, Farfetch etc? Instead of just syncing StockMutation i've decided to import all orders into Solidus as it allows us to keep all data in a central place

I think there’s a

channel

field on the order

That was my initial plan, but looking at the order importer I saw the store property and that got my thinking

You can model it as you want but the store is more something needed when you have multiple stores (like selling the same products in two different countries with different domains)

I agree

you can have different shipping methods or taxes per store
