@federico_calvo I ran into the need to set a margin based on supplier’s price. Price Rule takes care of that part.
Did you manage to solve your issue?
How about we propose and develop the following:
There should be a tool to “massive update” by a percentage, all prices in a list.
Perhaps even develop further such tool, so that it applies % increase/decrease to prices in an entire price list, and then also allows tags as differentiating items to apply a specific percentage to item prices in a list with those tags.
The tag functionality could be two options: From Base or From General % Change requested.
From Base: a child table in the tool where user selects a tag for item prices, and then a % change from actual price is applied.
From General % Change: Where the main % change is applied to all items in the list, and an additional % is applied after that for listed tagged items.
The change could also be “scheduled” in advance, with a datetime field up to milliseconds, for precision, so that you can pre-program your price changes.
What do you say we open a GitHub issue and develop it?
