# Lookback Credits
Lookback Credits is a feature that allows you to reward customers for purchases made before they became members. This helps drive conversions by showing non-members the value they missed and offering a limited-time opportunity to earn credits retroactively.
### How It Works
#### Customer Experience
* A non-member places an order
* They receive an email showing how many credits they would have earned as a member
* The email explains they can still receive those credits if they join within a set timeframe
* If they join within that window, credits are automatically awarded
* Credits are applied for qualifying orders placed before enrollment
#### Example
A customer places a $200 order while not enrolled. Your program offers 10% cashback. They receive an email letting them know they could have earned $20 in credits. If they sign up within 7 days, they receive those $20 in credits after joining.
***
### Configuration
To enable Lookback Credits, navigate to **Membership Program → Select membership tier → Benefits → Credits for Orders benefit**
#### Enable Lookback Credits
Turn this setting on to activate the feature.
#### Days to Look Back
Set how many days prior to enrollment to consider for eligible orders.
Example: If set to 7 days, customers will receive credits for orders placed up to 7 days before they join.
#### Max Orders
Set the maximum number of orders eligible for credit.
* Orders are processed from most recent to oldest
* Only the most recent orders up to this limit will be included
Example: If set to 1, only the most recent order will qualify.
#### Multi-Tier Programs
If you have multiple tiers with different cashback rates, you can select which tier is used for credit calculations and customer messaging.

### Customer Notifications
#### Native Email
Inveterate automatically sends an email after a qualifying order is placed. This email includes:
* The credits the customer would have earned
* The number of days they have to join
* A link to your membership page
* A summary of the offer
{% hint style="info" %}
Note: The credit amount is based on the order subtotal and may differ from the total paid.
{% endhint %}
#### Klaviyo Integration
If you are using Klaviyo, you can send custom emails using available properties, including:
* Credit amount the customer would have earned

### Credit Award Logic
#### When Credits Are Awarded
Credits are awarded when the customer enrolls in a membership with Lookback Credits enabled.
#### How Credits Are Calculated
1. Orders within the lookback window are identified
2. Orders are selected from most recent to oldest
3. Credits are calculated per order based on your cashback rate
4. Each order generates its own credit entry
Customers will see separate entries in their credit ledger for each qualifying order.
#### Eligible Orders
Only orders placed before the membership purchase are included. Orders placed at the same time as enrollment follow your standard Credits for Orders settings.

### Important Considerations
#### Lookback Window Timing
The lookback window is based on the time of enrollment, not when the email is sent.
Example:
* A customer receives a 7-day offer
* They wait 5 days to join
* Only orders within 2 days before enrollment will qualify
{% endhint %}

You can choose which tier’s benefit is used for calculations and messaging.
