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 |
