Amazon – Inventory Planning (Global)?

Hey all,

How do you typically forecast inventory? Is it a manual process with pulling several reports out of SellerCentral, then running your own calculations in excel?

We are in multiple Amazon marketplaces around the world, and I want to build a system that accurately forecasts what to order on a monthly basis. I know Amazon has an inventory planning tool but I haven’t found that to be very helpful.

Any tips & tricks appreciate!

thanks,
