# Exclude a customer from calculations in Fincome

## Can a customer be deleted from Fincome?

It is not **possible to permanently delete a customer** from Fincome, because the platform keeps a complete history of data to ensure consistency of calculations and analyses.\
However, you can **neutralize its impact on your metrics** by reducing the amounts of its invoice line items to zero.

This amounts to indicating that this customer no longer generates recurring revenue or recognized revenue, without altering the overall history of your billing.

## Steps to follow to stop taking a customer into account

1. Go to the **Data → Invoice lines**.
2. Search for the **exact name of the customer** in the search bar.
3. Select **all invoice lines** associated with this customer.
4. Click on **Edit selection**.
5. Replace the **amount excluding tax after discount** as well as **the discounts** with **0 the discounts in case you do not take them into account in your indicators, therefore which would be added to the amount excluding tax after discount)**
6. **Save** your changes.

## Result in Fincome

Once these steps are completed:

* the customer no longer contributes to the **MRR**,
* they no longer appear in the **Revenue Recognition**,
* and no longer affect any analyses related to **recurring revenue** (GRR, NRR, LTV, etc.).

The history of their invoices remains viewable in your data (but will be at an amount of 0).

## Best practices

* **Keep an internal record** of the reason for the exclusion (test customer, duplicate, internal customer…). You can for this [add a **dedicated analytical axis**](/en/conduct-in-depth-analyses/segment-your-data-with-analytical-axes/add-analytical-axes.md) (e.g. `Customer type = Internal`) and filter these values in your analyses.
* If you wish to **hide these customers from all analytical views**, you can then filter by this axis and **save the corresponding segment** (see the article [Using filters and breakdowns in Fincome](https://help.fincome.co/conduite-danalyses-approfondies/utiliser-les-filtres-et-la-decomposition-dans-fincome) ).
* To avoid neutralizing an active customer by mistake, check that they have **no ongoing subscription** before modifying their lines.
