The symptoms

A subscription change for a customer in your billing system can cause spurious movements in your MRR (caused by a subscription "overlap" or "gap").

For example: We have a customer with a €100 subscription, then a new subscription at €150 before the old subscription is cut off. In this case, we will have €250 of MRR over a short period instead of €150.

To remedy this phenomenon, you can merge subscriptions in your Fincome account. The last active subscription will then become the one taken into account in your calculations, and you will no longer have spurious MRR movements.

Merging subscriptions in Fincome

Go to the customer page (via "Analytics" > "My customers" or by searching directly for a customer via the search function). In the subscription section, click "Show chart" then "Merge subscriptions". You can then select directly on the chart two subscriptions you want to merge. Once validated, you will see a "link" icon appear on the "child" subscription, meaning this subscription has been attached to another subscription.

Once the subscriptions are connected, in the event of an overlap or gap, feel free to enable the neutralization rule.
