Credit & Billing Basics

NovaStack uses a prepaid credit system. You add credits to your account, and they are deducted daily based on active servers. No surprise invoices, no long-term commitments.

1 credit = €1.00. Your balance is shown in euros at the top of your dashboard.

• Credits are deducted once every 24 hours at 00:00 UTC.
• The amount deducted equals the daily rate for each server you keep deployed.
• Servers are billed daily whether they are running or stopped — stopping a server does not pause billing.
• To stop billing for a server, delete it from the dashboard. A server suspended for an empty balance also stops accruing charges.

Click Top Up in the sidebar footer or from the Billing page.

1. Enter an amount (minimum €5.00, maximum €500.00 per transaction).
2. Choose a payment method: Credit/Debit Card (via Stripe) or PayPal.
3. Complete the checkout. Credits are added instantly.

To avoid accidental suspension, keep a buffer of credits on your account and watch for the low-balance warnings described below. Automatic top-up is on our roadmap — until it ships, top up manually before your balance runs out.

When your balance gets low, NovaStack sends warnings:

1. Running low — the Billing page shows your estimated days of runway, turning amber when about a week of credit remains.
2. €0.00 balance — servers are suspended (stopped, not deleted). You cannot start them until you add credits.
3. After 7 days suspended — server data is permanently deleted. You will receive multiple email warnings before this happens.

To reactivate a suspended server, simply add credits and click Start.

Your full billing history is available under Settings → Billing. Each entry shows:

• Date and time of charge or top-up.
• Amount in euros (€).
• Server name and plan tier (for daily charges).
• Payment method (for top-ups).

Need a formal receipt or invoice for a top-up? Contact support and we'll send you one.

New customers can request a full refund within 7 days of their first payment (one refund per customer, applied to your initial purchase). Beyond that 7-day window, unused credits are non-refundable except where required by applicable law. To request a refund, contact support via the dashboard ticket system or email support@novastack.org.

Credits consumed by daily billing are non-refundable.
