Fincome gives you the ability to audit every billing line and adjust metrics according to special cases (VAT, discounts, canceled invoices, etc.), in order to build a tailor-made MRR. Correcting an invoice line lets you faithfully reflect reality: including a forgotten discount, correcting an inaccurate date or amount, or applying a retroactive reduction to a subscription. These adjustments ensure that your SaaS indicators (MRR, churn, expansion, contraction) remain accurate and up to date, thus avoiding distorted metrics.

Steps to correct or adjust an invoice line

There are two ways to correct or adjust an invoice line.

First option: From the customer page

From My Customers > the relevant customer's page:

1. Identify the relevant line: locate the invoice in question, then, by clicking on it, the invoice line that needs a correction (for example, an invoice where a discount was not applied or an incorrect date).
2. Choose the appropriate action: Click the "..." button to the right of this line to be able to edit it.
3. Edit the necessary fields: A form window opens with the line's details. Update the required information: for example the amount (including the forgotten discount or fixing an error), the period start/end dates if they were incorrect, or the type (one-off or recurring) of the invoice line.
4. Validate the correction: Save your changes by clicking Save. The platform will then update the invoice line. The correction is immediately taken into account in Fincome, with no further action required on your part.

Second option: From the "Data" tab

1. Go to the "Data" page in Fincome, then "Invoice lines"
2. Note some information about the corresponding invoice line (customer name, invoice number, invoice line number...) to find it/them
3. Check the relevant invoices then click "Edit" on the right
4. Edit the necessary fields: A form window opens with the line's details. Update the required information: for example the amount (including the forgotten discount or fixing an error), the period start/end dates if they were incorrect, or the revenue line's category if needed.
5. Validate the correction: Save your changes by clicking Save. The platform will then update the invoice line. The correction is immediately taken into account in Fincome, with no further action required on your part.

FAQ

→ Does correcting an invoice line retroactively change my indicators (MRR, churn, etc.)?
Yes. Any correction applied to an invoice line (amount, period, revenue type, discount, etc.) is immediately taken into account by Fincome and can modify your past and future indicators. This lets you realign your metrics with economic reality, even retroactively.

→ What is the difference between correcting an invoice line and changing a calculation option?
Correcting an invoice line acts directly on the source data (the invoice itself). Calculation options, on the other hand, define how Fincome interprets this data (for example: churn recognition, handling of discounts, neutralization of gaps). The two approaches are complementary: first correct the data if it is incorrect, then adjust the options if the observed behavior is related to calculation rules.

→ Why does a corrected invoice keep generating MRR even though the period has ended?
It depends on the configured calculation options. For example, if the "MRR recognition after the end of the last billed period" option is enabled, Fincome may continue recognizing MRR as long as the subscription is not explicitly canceled. In that case, check the subscription's status or adjust the corresponding option in the settings.

→ Can I correct several invoice lines at the same time?
Yes, from the Data > Invoice lines tab, you can select several lines and edit them in a single action. This is particularly useful for applying an identical correction (discount, revenue category, dates) to a set of invoices.

→ Do corrections impact my exports and shared reports?
Yes. All Fincome reports, dashboards, and exports use the corrected data. Once the change is saved, it is automatically reflected in all your analyses and shares, with no additional action.
