% sales margin

I am wondering.
I buy items and book in stock. And then I sell it on price that I have calculated on a fixed price.

Is there a way I can just set fixed margin % that calculates the sell price from the stock cost price?

Sincerly

No there isn’t at the moment. However, this topic is already an idea for future implementation:

For now your best option is to perform a batch update on Inventory Items whenever the cost changes. Otherwise, you can always fallback to the manual way of updating the price of each sale.
