I buy salt in bulk, repack it and sell it to wholesalers. When I buy the raw salt goes under inventory? And when I sell it it goes under sales?

I've got you covered, flamingosalt@gma.
 

Once an inventory item is purchased, it'll go to the income account you've set up. This will affect your inventory or the cost of goods sold (COGS).

If the inventory items were set up, there are two ways on how to track your sales to remove the stock from inventory:

• Create an invoice if you’ll get paid later.
• Add a sales receipt if your customer paid on the spot.

I've added this article for additional information about inventory tracking: Set up and track your inventory in QuickBooks Online.

Additionally, I've added this article that'll help you fix inventory issues: Fix negative inventory issues in QuickBooks Online.

I'm still here if you have other questions with regards to tracking your sales. Just post your questions here, I'll respond as soon as possible. Keep safe.
