Term given for cash to buy stock

I’m trying to work out the correct term to use.

Lets say £1000 of stock has been sold. I would put this money aside in order to purchase more stock in the future.

I’m not sure if Cost of Goods Sold is the correct name. Quickbooks out of interest uses ‘Stock Assets’, but this is referring to inventory (not the cash reserved to purchase more). Maybe ‘Cost of Sales’ or ‘Sales of Product Income’, which I think is referring to revenue.

It’s not for accounting, more of a heading to use on sales metrics charts etc.

Is there a commonly used term for this?
