How are people handling estimates with Zoho inventory?

How are people handling estimates with Zoho inventory?

We are often using Zoho Books for estimates that then get converted to invoices within Books.

We would like the sales team to migrate entirely to Zoho Inventory and no longer need to use Zoho Books so that they are only on one system.

How are people managing with estimates for Zoho Inventory since they can't be made there? Are you making one in Books then re-making the SO/Invoice in Inventory?

Hopefully Inventory will incorporate this feature soon or release an "all in one" Books and inventory solution.
