Credit, bills and invoices

Last updated on Nov 10, 2026

Your team pays in advance with credit, in euros. Credit belongs to the team, not to the person who added it, and it cannot be moved to another team or paid out.

Add credit

Your team's owner and admins add credit on Billing. The page shows the least and the most you can add at a time. You pay on Revolut's payment page, and your card details go to Revolut, not to us. The credit reaches your team once Revolut confirms the payment.

What comes out of it

Each set's monthly price comes out of your credit, once, at the start of each month. A set's months start when its free trial ends, or when you install it if it had no trial. If your team had never paid when the trial ended, the set's months start instead on the day it first pays. A set with no apps left is not charged.

Billing is held while every app of your team is stopped. A month that falls due in that time is charged when an app starts again, and a month held from start to end is not charged. Charges already made are not paid back.

History on the Billing page shows each payment and charge, with its day and amount.

When credit runs out

The dashboard warns your team when credit runs low and when it runs out. We charge fees when they fall due, even if your credit does not cover them, so your credit can fall below zero. A team that has never paid is charged nothing after its trial ends until it first pays, as The free trial says.

While your credit is below zero, or at zero outside a set's free trial, your team cannot start new installs or updates. If it stays below zero, every app of your team stops 3 days after we first find it there, and the dashboard shows the date. Your apps and their data stay. Add credit and your apps start again by themselves, apart from any you stopped yourself.

A balance below zero is money your team owes. You can pay it by adding credit, which pays it off first, or by bank transfer. Section 7 of our terms sets this out.

Invoices and VAT

Section 5 of our terms says when we issue an invoice, what it shows and how VAT works. For a question about an invoice, or to give us the legal name and address it should carry, write to contact@clusterz.eu.

Unused credit

If you choose to leave, unused credit is not paid back. Section 5.3 of our terms lists the cases where it is.
