Errors with balance

Good afternoon!

There is a problem when adding products to the warehouse, especially through PW WooCommerce Bulk Edit.

It consists in the fact that when you open a list or product, it loads the current balance value, for example, 10, if at that moment the client placed an order, for example, for 5, then it is deducted from the balance.

It turns out that in an open editor you have a value of 10, and when you add, for example, +2 and press save.

12 is used in the store, although in fact it is already 5 i.e. should have been 5+2.

PW WooCommerce Bulk Edit pro plugin needs improvement
1. Which will allow you to drive (current value) +N into the product at the time of saving.
those. a list of goods to which you need to add N to the balance, and when saving separately, each product is made + And without disturbing the balance and work of customers.

2. The history of these statements (lists of increases) Date, author, note.

3. Search through these stories statements.

4. Differentiation of user access to the lists: only viewing the created ones, creating a list only with an increase, creating any one with plus and minus to the product.

Thank you!
