Billing
Credit, invoices, and how services are billed.
Futrou runs on prepaid credit. Every workspace has a credit balance, shown in its chosen currency, and services are paid for out of that balance as they run. A workspace can’t go negative — if credit runs out, billable services are suspended until the balance is topped up.
Topping up credit
Add credit from Billing → Order Credit, choosing an amount in your workspace’s currency (CZK 100–10,000, or €5–450). Every order needs billing details on file first — you’re prompted to fill them in if they’re missing.
Two payment methods are available:
- QR Payment (bank transfer) — shown only for Czech and Slovak billing addresses. Pay by scanning the order’s QR code or transferring manually using the variable symbol and account details shown on the order; payment is matched automatically once received. Paying this way also skips VAT for eligible addresses.
- Credit / Debit Card — processed by a third-party payment provider, available only when your workspace currency is EUR. Placing the order redirects you to a hosted checkout; credit is added once the provider confirms payment.
Vouchers
A voucher is a code worth a fixed amount of credit in one currency. Redeem one from Billing → Vouchers → Redeem Voucher by entering its code — the credit is added to your workspace immediately, provided the voucher’s currency matches your workspace’s currency, it hasn’t expired, and it hasn’t already been used. Each voucher can only be redeemed once.
You can also buy a voucher yourself from Billing → Vouchers → Buy Voucher, to gift credit to another workspace. Its price is deducted from your own workspace’s credit balance immediately at purchase — buying a voucher is itself a transaction, not an order, so it isn’t paid by bank transfer or card.
Billing details
Your billing address is used on invoices and orders, and can be set as an individual or a business. As a business, you can also record a company number and VAT number. Update it any time from Billing Details in workspace settings — it’s independent of your workspace’s display name.
Orders, invoices, and proforma invoices
Buying credit creates an order. While an order is unpaid, it has an associated proforma invoice — a preliminary document with payment instructions, not a tax document. Once the order is paid, a proper invoice is issued for it instead. Both are generated automatically; you never create them by hand.
Find both under Billing → Orders, expandable per order, or Billing → Invoices for invoices on their own. Each can be previewed, downloaded as a PDF, or fetched as a payment QR code.
An order moves through these statuses:
| Status | Meaning |
|---|---|
| Pending | Awaiting payment. Has a proforma invoice. |
| Paid | Payment received; an invoice has been issued. |
| Canceled | Canceled before payment — no charge occurred. |
| Refunded | Paid, then refunded. |
Recent spending
The Recent Spendings list on the Billing page shows a running history of what’s been deducted from your balance, including currency conversions if your workspace currency differs from a charge’s original currency.
How services are billed
Billable services on Futrou are metered per minute and charged against your workspace’s credit balance.
Serverlets
A serverlet is billed per minute of instance uptime, at its plan’s per-minute rate. If a serverlet runs multiple instances, each running instance is billed. A serverlet scaled down to zero instances — whether by hand or through autoscaling — has nothing running, so nothing is billed for it during that time; billing resumes as soon as an instance starts again.
The Billing page shows two cost figures for this reason: Monthly Costs, the projected cost at your current instance count, and Maximum Monthly Costs, the projected cost if every serverlet scaled to its configured maximum. Actual spend for a given month lands somewhere between the two, depending on real usage.
Other services
Proxies, DNS zones, and other services follow the same per-minute model, billed at their own plan’s rate for as long as they exist.
Plan and usage limits
Your workspace has limits on how many of each resource it can hold at once — serverlets, proxies, DNS zones, projects, and so on — based on your plan. Current usage against these limits is shown on the Plan & Limits page in workspace settings.
