Invoice gaps / overlaps

This article describes how the "Neutralization of billing period gaps and overlaps" setting works. You can change this setting on your dashboard in the Settings > Calculation options section.

1. Invoice gap

An invoice gap corresponds to an interruption between two successive invoices of a subscription. This means that after an invoice expires, a period elapses with no active billing before a new invoice begins. This case typically occurs in annual SaaS when the customer renews their subscription late, creating a temporary billing gap.

2. Invoice overlap

An invoice overlap occurs when two invoices (generally for the same subscription or customer) cover periods that partially intersect. In other words, a new billing period starts before the previous one has ended, creating a temporal overlap.

3. Options in Fincome to correct these situations

To avoid these problems, Fincome provides specific calculation settings that automatically adjust the handling of billing overlaps and gaps. These options, accessible via Settings > Calculation options on your Fincome Dashboard, let you neutralize these situations and make your revenue metrics more reliable. By clicking on "Neutralization of gaps and overlaps", you can:

• Neutralize only overlaps
• Neutralize only gaps
• Neutralize overlaps and gaps
