In our company we both pay Invoices before and after receiving the goods. Usually we do it before receiving the goods. 

I have been looking at the Zoho Inventory addon integration and it seems like the purchase receives module only lets track the status of the shipment if the invoice has not been generated yet. In this case it is completely useless for us as many times the invoice is generated before the shipment. After receiving the goods is where we calculate and assign the landed costs to that invoice. 

Example: We buy in China 600 boxes. We pay $8000 for that manufacturing. The invoice for that goods is already done. We add it to Zoho Books. Then we get some freight forwarder to ship out goods from China to USA (we will be invoiced for this sea freight 2 months after receiving the containers). Once received the goods at the USA we will add the landed costs (Unload costs, customs cost, freight cost (2 months later).... etc. What I am trying to understand is if I can track the container status within Zoho Books by clicking on that invoice and putting it in the state of "In transit". Right now our control regarding which containers are in the sea in transit and which ones have not been shipped yet or even which ones have arrived is quite a mess and would love to have it fixed.

I am missing something or does it work this way and this can not be done?
