Can you set different commission and discount rates per ambassador?

Yes, you can do this with our tiers feature.

Once you've added an ambassador, go to the ambassador tab and click Edit next to their name.

Then click update next to tiers. You can then set a custom commission and discount rate.

To create additional tiers, click the "Create Tiers" button in the top right.

To update a tier, simply click the edit icon next to the tier. Changing the discount and commission for the tier will change it for all ambassadors on that tier.
