Woocommerce = Zoho Inventory = Zoho Books integration

Woocommerce = Zoho Inventory = Zoho Books integration

Hello, I have a question about integrating Woocommerce and Zoho Inventory + Books.

As I understand ZI can be synced with Books, so every Sale Order that falls from Woocommerce will be synced with Books, right?

So, here is the part which is not clear - what is the use of some integrations of Woocommerce=Books, if the order is pulled from Woo > Zoho Inventory and then to Books?

I mean, there are a few dedicated plugins (Woo=Books directly)... am I missing something here?

Is this a correct connection? (We already have a Woocommerce shop ready)

[ Woocommerce=Zoho Inventory=Books ]

Or would it be better to integrate first Zoho Inventory with Books, and then fetch products from Woocommerce with initial sync?

[ Zoho Inventory=Books > Fetch products from Woo to ZI ]

Would really appreciate any advice, thanks.

And what are you guys personally thinking about Roadmap integration (Woo=ZI)?

The second one is by CRMPerks, and it claims to also (!) sync Woocommerce with Zoho Books, CRM, Invoice and Inventory. Sounds sweet, but does it actually work?

If the the mentioned above doesn't work, we will be considering using this plugin:

Any thought about this one?

Thanks...
