Billing

Nacre uses Stripe for every payment. When you pick a plan, we redirect you to Stripe Checkout with a pre-built session — card is entered on Stripe's domain, never ours. After a successful checkout, Stripe fires a webhook to the control plane and we start provisioning your VM.

Billing cycles

Monthly or annual, renewed on the anniversary of signup

Supported payment

Cards (global) + wallets (Apple Pay / Google Pay) via Stripe

Invoicing

Emailed automatically on each renewal; VAT/GST lines included where applicable

Currency

USD. Your bank may convert at the market rate.

Dashboard → Billing opens the Stripe Customer Portal (same signed link Stripe gives every merchant). From there you can:

• Update your card or switch payment method.
• Change the billing email (separate from the login email).
• Download invoices and receipts.
• See upcoming charges.
• Cancel the subscription.

The portal is Stripe-hosted — we don't mirror these flows in our own UI because Stripe already does it well, securely, and without us ever touching your card data.

Upgrades are instant. Stripe pro-rates the difference to the end of your current billing period and charges the delta. Your VM resizes in place within a minute.

Downgrades require a controlled migration (disks can't shrink in place on Hetzner). Email support@nacre.sh with the target plan and a preferred window; we handle the snapshot, new VM, restore, and DNS cutover, then pro-rate the credit.

Your first paid subscription is refundable pro-rata for 14 days from the initial charge. Ask and we'll refund the unused days.

• Pro-rata means: 14 days into a 30-day month, you get ~16/30 of the fee back.
• Applies once per account, on the first paid subscription.
• Doesn't apply to LLM provider spend — that's billed directly by your provider, not us.
• After 14 days, cancellation stops future renewals but we don't refund the current period.

Request a refund from support@nacre.sh or via the Customer Portal.

If a renewal charge fails — expired card, insufficient funds, bank decline — we don't pull the plug immediately. You have a 14-day grace period, and we email you at each escalation point:

Cancel anytime from Customer Portal → Cancel subscription. Your VM keeps running until the end of the current billing period — no "we cut you off mid-month" trick. At period end:

1. A final backup is taken.
2. The VM is deleted from Hetzner.
3. Your backup is retained for 90 days. Resubscribe in that window and we restore onto a fresh VM.
4. After 90 days the backup and per-customer key are purged — see Backups.

Stripe Tax computes VAT / GST / sales tax where we're registered to collect, and adds it to your invoice. If you're a business with a valid VAT ID, enter it in the Customer Portal to reverse-charge where applicable. Invoices include your company name, address, and VAT ID if set — suitable for expense reimbursement.

Nacre charges

Fixed monthly or annual plan fee — VM, bandwidth, backups, support.

Nacre does NOT charge

LLM inference, channel fees (Meta WhatsApp), or any usage-metered item.

Your LLM provider charges

Token usage on your own key. You see this on their dashboard, not ours.

This is the BYOK trade: predictable Nacre bill, variable provider bill. See Providers for how to cap your provider spend.
