By turning on cash to gift card conversion your ambassadors can transfer cash in their Cash Balance to gift card with your brand, and get a bonus when to convert (the Conversion Bonus Percentage).
You will be credited the cash minus 15% to your Reward Budget Account.
You can set cash to gift card conversion in your settings.
Under Settings -> Sales & Discounts -> Gift Card you can turn on the Cash to Gift Card feature.
For example: if an ambassador transfers $100 and your brand has a conversion bonus of 50%, that means the ambassador will get $150 gift card added to their Gift Card Balance with your brand, which can be withdrawn and spent in your brand webstore. You will then be given $85 to your Reward Budget Account which you can create missions with.
