It is absolutely horrible adjusting prices on products and services right now, especially if I have a lot to update. I have to find the item, click it, then click edit, adjust the pricing, save, then go back to the products page, re-sort the items and find the next one.
I would like to see something like an "edit pricing" mode, where I can change prices on any items from the main product list, all on one page.
It would also be nice when adjusting the price of an item in an invoice, if something popped up to ask if you want to update the product with the new price, click yes, and it's done. No having to navigate to another screen.
Another option could be the ability to export the product list to excel, then import the list with the updated pricing.
