Thanks for joining the thread, BUTTERFLY11.

I'll be glad to share what I know about  COS and COGS.

Cost of Goods Sold, (COGS), can also be referred to as cost of sales (COS), cost of revenue, or product cost, depending on if it is a product or service. It includes all the costs directly involved in producing a product or delivering a service.

The Cost of Sales and Cost of Goods sold both track how much it costs a business to produce a good or service to customers. 

There is almost no difference between the two. The terms are typically used interchangeably in accounting

I recommend consulting your accountant for help in selecting which to use in tracking stocks.
