Tracking Refunds

If you are tracking Billed or Purchased events, then tracking refunds is a simple addition. You can add the Refunded event, and pass in a negative Billing Amount property. This will help correctly calculate metrics like Total Lifetime Value. Make sure to use the same property name that is tracking your revenue information, If your property name is different from Billing Amount.

Example

To demonstrate, below is an example table of values for a particular person 1234567. Notice that all revenue information is passed under the same property, Billing Amount.

Identity	Timestamp	Event	Prop:Billing Amount
1234567	1305072000	Billed	90
1234567	1305080000	Refunded	-90
1234567	1307600000	Billed	50
1234567	1309900000	Billed	45
