## Billing basics

### How does the billing structure work?

#### On-demand customers

On-demand customers are billed monthly. The credit card on file is automatically
charged through Stripe upon invoice generation.

- Invoices bill active seats in advance for the upcoming period
- Any seat count changes made during a previously billed period are charged in
  arrears on a prorated basis on the next invoice, as well as billed in advance
  on all subsequent invoices until the customer makes further adjustments

#### Contract customers

**Contract customers** are billed annually and upfront according to the terms
in their contract.

- Committed seats are billed annually
- Overages for uncommitted seats and usage are billed in arrears separately on a
  basis specified in the contract
- Standard payment terms are **Net 30**, unless otherwise specified in the agreement

### What payment methods does Cube accept?

#### On-demand customers

On-demand subscriptions must be paid by credit card via Stripe. Your card is
automatically charged on a recurring subscription basis at the start of each
billing cycle.

<Info>
Cube does **not** support ACH or wire transfer payments for on-demand payment plans.

#### Contract customers

Contract customers can pay via:

- **Invoice billing** (e.g., Net 30 terms) — Payment terms are defined in your
  contract and reflected on your invoice.
- **ACH / wire transfer** — Bank details (Stripe-managed virtual accounts) are
  listed directly on the invoice. Please reach out to
  [support@cube.dev](mailto:support@cube.dev) if you require validation.
- **Credit card** (via Stripe) — Contract customers may also pay by credit card.

### How can I update my payment information?

To update your payment information, log in to your Cube account and navigate to
the billing settings page.

If you need assistance confirming or updating your account email, please reach
out to [support@cube.dev](mailto:support@cube.dev).

### What happens if my credit card payment fails?

If your credit card payment fails:

1. **We automatically retry the charge** — Stripe will automatically retry the
   payment using the card on file. Sometimes failures are temporary (e.g.,
   insufficient funds, bank block, expired card).
2. **You may receive an email notification** — If the payment continues to fail,
   you'll receive an email prompting you to update your payment method.
3. **Update your card** — You can update your card through the billing settings
   page. Once updated, the system will automatically retry the charge.
4. **Continued failed payments** — If payment isn't resolved after multiple
   attempts, your account may be restricted or suspended until the outstanding
   balance is paid.
