Plugin to increase stock effectively

I’m looking for a WooCommerce extension which will make it easier to update the stock after I have purchased new products for sale.

I’m selling shoes with different models, colors and sizes. Let’s say I purchase 200 pair of shoes to increase the stock of a bunch of different shoe sizes etc. It could be 2 pair of black shoes size 9, 1 pair of black shoes size 8 etc etc.

How would I go about updating the new stock effectively? It could be by scanning a barcode for each product variation or any other efficient way….

Thanks!
