Billing

Manage credits, monitor usage, and track spending for GPU instances.

Credit system

• 1 Credit = $1 USD of GPU usage
• Credits never expire
• Credits are shared across team members
• Pay-per-second billing: credits are deducted continuously based on your hourly rate, so you pay only for the exact time your instance runs
• Your hourly rate tracks the provider's current price for the whole life of an instance. If the underlying price moves, charges from that point onward use the new rate. Usage already billed is never recalculated, and any discount on your account continues to apply

• Minimum deposit: $15
• Instant credit delivery

Dashboard overview

The Overview section shows your balance and live GPU usage at a glance.

• Available Balance: Credits ready to spend on GPU deployments. An account-status indicator (for example, "Account in good standing") sits below the value.
• Total Spent: All-time GPU and storage spend for the team.
• Active: Number of GPU instances currently running.
• Burn Rate: Current hourly cost across all running instances.
• Est. Runtime: Estimated time remaining at the current burn rate. Shows N/A when there is no active spending.

Usage analytics

Track deployments, GPU spend, and volume costs in one place.

A time-range selector at the top of the panel (default: All Time) filters every metric and the deployment list below.

• Deployments: Total deployments in the selected range
• GPU Spend: GPU compute spend in the selected range (also shows the billed-instance count)
• Active Volumes: Currently active persistent volumes (also shows the total volumes ever created)
• Volume Cost: Accumulated storage spend in the selected range

• GPU model, count, VRAM, and hourly rate (for example, 1x L40S PCIe - 48GB GDDR6 - $1.07/hr)
• Instance ID
• Provider and region
• Duration and timestamp
• Total cost and status (active or terminated)

Use the analytics view for:

• Cost analysis by GPU type
• Spending pattern review across time ranges
• Project cost tracking
• Usage optimization

Billing for a stopped instance

Stopping an instance keeps it and its disk while releasing the GPU. You are billed for the disk, not the GPU, for as long as it stays stopped.

• The stopped rate comes from the provider and covers the retained disk, plus the public IP where the provider charges for one.
• Any discount on your account applies to the stopped rate exactly as it does to the running rate.
• Charges run on a five minute cycle. Stopping and starting both settle the elapsed time at the outgoing rate first, so a stop landing mid-cycle is not billed at the wrong rate for that slice.
• Usage figures, invoices, and the deployment list pick stopped periods up with no change.
• When a provider parks your machine from its side, you are charged the stopped rate for that period, not the running rate.

Stopped rates are shown to four decimal places. At two decimal places most of them round to $0.00 and read as free, which they are not.

Deposit history

View all credit deposits and top-ups for your team.

A time-range selector at the top (default: All Time) filters the summary metrics and the deposit list.

• Total Deposited: All-time deposit amount across the team
• Avg Deposit: Average value across completed deposits
• Total Deposits: Count of all deposits with a completed-vs-pending breakdown

• Status badge: Pending or Completed
• Date and time of the deposit
• Source label: Custom $X, a preset package (e.g., $100 Package), or Auto Top-Up
• Payment provider: Stripe (card) or CopperX (stables)
• Amount in USD and the credits awarded
• Receipt button on completed deposits for downloading the invoice

A deposit that gets stuck pending because a confirmation was delayed or missed is detected and credited to your balance automatically, with no need to contact support. Deposits that were genuinely abandoned or expired are cleared from the list instead of lingering as pending.

Use the deposit history for:

• Payment verification
• Expense tracking
• Receipt downloads for accounting records

Low-balance warnings

Warnings are based on how much runtime your balance buys at your current burn rate, not on a fixed dollar figure. The same alert means the same thing whether you run one small GPU or a large cluster.

Spheron emails you as your estimated remaining runtime crosses each of these thresholds:

A balance-exhaustion notice follows if the balance actually runs out. These emails are always sent and are not affected by the marketing toggle in User settings.

Enable auto top-up to recharge automatically instead of relying on the warnings.

Auto top-up

Auto top-up prevents unexpected instance termination by automatically recharging your account when credits run low.

1. Add a payment card from the Add Credits tab. Once saved, it appears in the Saved Card panel under Auto-Pay.
2. Set Top up when below between $5 and $500 (for example, $10)
3. Set Amount per top-up between $15 and $5,000 (for example, $50)
4. Toggle Enable auto top-up on

• When your balance falls below the threshold, the platform charges your saved card for the top-up amount.
• A 5-minute cooldown between charges prevents duplicate billing.
• If a charge fails, the platform disables auto top-up and emails you a notification.
• Auto top-up charges appear in Deposit History labeled "Auto Top-Up".

For long training runs, auto top-up prevents instance termination due to insufficient credits mid-job.

Billing details

Add your company name, registered address, and tax ID to your account so they appear on every future card-payment invoice automatically. Stripe stores this information once and applies it to all subsequent charges.

• Issuing invoices with proper legal entity information for accounting and procurement
• Tax compliance: VAT, GST, EIN, or other regional tax identifiers
• Expense reimbursement and audit trails that require the registered business name and address

Configure billing details

Update or remove details

Click Manage on Stripe at any time to change company information, update the address, swap the tax ID, or change the invoice email. Updates apply to future invoices only; previously issued invoices are not retroactively modified.

Access past invoices

Stripe emails each invoice to the configured invoice email address. Past invoices are also available in the Stripe billing portal via the same Manage on Stripe button.

Team discounts

Volume-based and admin-assigned discounts apply automatically. The discounted price appears directly in the GPU listings on the dashboard when your team has an active discount.

• The higher of volume-based or admin-assigned discounts is applied automatically
• No action is required; discounts apply as long as you are authenticated

To inquire about discount eligibility for high-volume usage, use the chat widget on app.spheron.ai or email info@spheron.ai.

Best practices

• Start with $50-$100 to understand usage patterns
• Monitor balance regularly for long-running instances
• Enable Auto Top-Up to avoid unexpected terminations
• Watch for the low-balance warning emails as your runtime drops
• Use custom amounts for precise budgeting

• Review usage analytics to identify expensive deployments
• Terminate unused instances promptly
• Stop an instance you will come back to, so the GPU stops billing while the disk is preserved
• Use Reserved GPUs for long-term workloads (30-50% savings)
• See Cost Optimization for GPU tier selection and Spot strategies

• Card payments are Stripe-encrypted and PCI compliant
• Stables payments are settled on-chain via CopperX
• Card data is never stored on Spheron servers

Frequently asked questions

Q: What happens if I run out of credits?

A: Instances terminate automatically to prevent overcharges. Add credits to resume.

Q: Does a stopped instance still cost credits?

A: Yes, at the stopped rate, which covers the retained disk and public IP rather than the GPU. See Billing for a stopped instance.

Q: Do credits expire?

A: No. Credits never expire and remain available indefinitely.

Q: Can team members share credits?

A: Yes. Credits are shared across all team members.

Q: How quickly are credits delivered?

A: Instantly upon payment confirmation, for both card and stables payments.

Q: What are the deposit limits?

A: Minimum: $15 per deposit. Maximum: $5,000 per deposit.

Q: Are there hidden fees?

A: No. 1 credit = $1 USD of GPU usage. No additional fees.

Q: Can I get a refund?

A: Credits do not expire, so they retain value. Contact support for specific refund inquiries.
