When creating or editing the Package associated with your lead, you'll have the ability to add print credits to your Package offerings.
First, go to the Shoot Details section and click the Add a Package button.
Enter your Package Details:
Next scroll to Print Credits to decide if you'd like to include print credits with your package cost.
Here you can select a monetary amount of credit to provide to your client. Your client will be able to use this towards buying prints from their gallery. This amount will be included in your total package price, but will only be deducted from your earnings after your client uses the print credits. To learn more about how print credits will be deducted from your earnings, check out the Print Cost help article.
