Our invoices are generated automatically via our billing portal (Stripe). At the beginning of every billing cycle, you receive an invoice for the booked package of the upcoming period.
How do our invoices work?
Since our pricing model is based on data volume and not on seats, your invoice is usually very simple: You pay a fixed amount for your chosen package. The invoice only looks more complex if you perform an upgrade in the middle of the month (e.g., switching from the “Starter” package to the “Business” package). In this case, our system automatically offsets the unused time of the old package against the runtime of the new package.Example calculation for an upgrade
Suppose you switch your package on August 16th. Your next invoice on September 1st would look like this:| Description | Amount |
|---|---|
| Adjustments (Aug 16 - Sep 1) | |
| Remaining time on “Business Package” after Aug 16 | €100.00 |
| Unused time on “Starter Package” after Aug 16 | -€50.00 |
| Upcoming Month (Sep 1 - Oct 1) | |
| Business Package (Monthly) | €200.00 |
| Subtotal | €250.00 |
| VAT (19%) | €47.50 |
| Total | €297.50 |
Explanation of line items
An invoice after a switch often consists of two parts:1. The upcoming month
This is the standard part. You pay in advance for the next full month of your new package (in the example, the “Business Package” for €200).2. Adjustments for the previous month (Proration)
This section appears only if you have made changes. The system calculates billing down to the minute:- Unused time (Credit): Since you paid for the old “Starter Package” for the whole month in advance but stopped using it as of the 16th, this amount is credited to you (in the example -€50).
- Remaining time (Charge): You have already used the services of the “Business Package” starting from August 16th. This partial amount is now charged to you (in the example €100).
