We offer on demand in house printing for some of our Vendors for which we charge a small fee.
We currently handle payouts outside PuppetVendors so can deduct print fees from payouts automatically, but would like to migrate payouts into the platform and this feature is essential for us.
For example for these products, we'd like to be able to charge our standard 20% Commission as with all products, and assign an additional to flat $X print fee for specific items (this can be by SKU or other means is fine).
Currently we can set a predefined print fee for individual items, but with a large number of vendors and products calculating and setting up a unique fixed fee that encapsulates XX% + $X relative to the cost of each item is not practical.
We would rather be able to assign an Add On print comission of $1, $2, etc for different print formats to specific items in addition to and on top of their base 20% Commission to cover print fees.
The result would ideally be:

All standard products: 20% commission + $0 Print Fee
In house print product A: 20% commission + $2 Print Fee
In house print product B: 20% commission + $1 Print Fee
In house print product C: 20% commission + $2 Print Fee
And so on.
This feature would be enormously beneficial for us and would enable us to migrate our payouts into to PuppetVendors.
