Started my own store recently and now looking for some apps to enhance it. Of course started from digging through a ton of "Top any number here apps for your super-duper Shopify store" lists on Google.
But most of them look like a sheer ad, so I, frankly, doubt their relevance and transparency (and aforementioned too, as it is a blog of some ERP).
Anyway, my question is about some proper inventory and automated invoices creation apps, also some advice about instant "buy" button would be great. Could you please suggest some and share some experience about handling product variants.
