Why does my Repeat Customer summary not match the Product-level table?

It is expected that the Repeat Purchase Summary and the Repeat Purchase Behaviour by Product table may show different repeat customer counts. This is because they are calculated at different levels within MerchantSpring.

Channel-Level (Repeat Purchase Summary)
The Repeat Purchase Summary calculates repeat customers at an account or channel level based on your selected filters (such as date range and channel).

A customer is counted as a repeat customer if they place more than one order within the selected period, regardless of which products they purchased.

For example:
If a customer buys Product A and later buys Product B, they qualify as a repeat customer at the channel level.

Product-Level (Repeat Purchase Behaviour by Product)
The Repeat Purchase Behaviour by Product table calculates repeat customers at an individual product level.

A customer is only counted as a repeat customer for a specific product if they purchase the same product more than once within the selected period.

Using the same example:
If a customer buys Product A and then Product B, they are considered a repeat customer at the channel level, but not at the individual product level.

They would only appear as a repeat customer in the product-level table if they purchased Product A twice (or Product B twice).

Why the numbers can differ
The summary aggregates repeat behaviour across the entire channel. This means it can include customers who purchased multiple different products but did not repurchase the same SKU.

As a result, the Repeat Purchase Summary total may be higher than the repeat customer count shown in the product breakdown.
