Recording Shopify/Amazon fees in Zoho Books - Zoho Inventory

We are currently flushing out the connections between Shopify/Amazon and Zoho Inventory. For other users of Zoho Books - Zoho Inventory, where and at what point do you record the merchant fees associated with theses channels? I have gotten mixed responses telling me to add them as adjustments, bank charges, expenses or even as line items.
