Billing

How does Sync Labs billing work?

This page describes subscription + usage plans: Hobbyist, Creator, Growth, and Scale. Organizations enrolled in credit billing use Hobby, Starter, Pro, or Team instead. Check your Studio billing page for your organization’s plan and billing model. For credit plans, see Credit Billing.

On usage billing, your subscription unlocks higher limits, premium features, and discounts, while you pay for what you generate. Lip sync usage is calculated per output frame, with per-second rates (at 25 fps) ranging from $0.04 (lipsync-2) to $0.133 (sync-3).

Model pricing at a glance

Lip sync rates below are per-second equivalents at 25 output frames per second, not flat prices per second at every frame rate. The charge is the output frame count multiplied by the model’s per-frame rate for your plan. Use the cost estimate with the expected billable duration and frame rate before submitting. Text-to-speech and dubbing are billed per second of audio, independent of frame rate.

text-to-speech: Hobbyist / Creator $0.004/sec, Growth $0.0038/sec, Scale $0.0032/sec ($0.24 / $0.228 / $0.192 per minute). These are the current standard rates, with plan discounts included. Credit plans use 0.4 credits/sec.

dubbing: Hobbyist / Creator $0.10/sec, Growth $0.095/sec, Scale $0.08/sec ($6 / $5.70 / $4.80 per minute). Plan discounts are included. Each job’s dubbed audio duration is rounded up to a whole second; lip sync is charged separately. With your connected ElevenLabs key, ElevenLabs bills the dubbing audio directly.

The updated dubbing rates are rolling out at eligible subscriptions’ scheduled renewals; current rates apply until then. Negotiated enterprise and pilot rates remain unchanged. Credit-billed accounts use credit pricing.

For full plan details, see the pricing page.

Free trial

New to sync. labs? Every free account gets 3 free video generations per month, up to 15 seconds each. All three can use sync-3 or another free-eligible video model; there is no separate sync-3 quota. Text-to-speech and dubbing share a separate allowance of 10 monthly audio generations, up to 3 of which can be dubbing. Free built-in text-to-speech accepts up to 320 characters and 20 seconds of speech per request. No credit card required. The exact models available to your account are returned by the List Models endpoint.

This is a great way to explore Sync Labs and test our models before committing to a plan.

Subscriptions

When you subscribe, you unlock higher concurrency, longer video durations, features such as reasoning mode and team workspaces, access to the models enabled for your account, and usage discounts on higher tiers. Use the List Models endpoint to see the models your API key can use.

On usage-billed plans, generation usage is billed separately from your subscription. The subscription includes no bundled video generations or generation credits. Limits such as “5 voice clones” and “10 concurrent jobs” describe saved voices and simultaneous jobs, not included videos. Check the estimate before submitting; generation usage is charged in addition to the subscription.

See our pricing page for plan details and model rates.

Usage billing

You’re billed based on what you generate. For lip sync, we calculate usage by counting the frames in your output video and multiplying by the per-frame price for the model you used. Each model has different rates—see our pricing page for details.

With sync_mode: "cut_off", the processed duration is the shorter of the video and audio tracks. Billing uses that processed duration, rather than charging for the discarded part of the longer track. For example, a 10-second video with 30 seconds of audio processes and bills 10 seconds. Supply that duration when using the cost-estimate endpoint.

Usage invoices are generated automatically and charged to your saved payment method. Check the Billing page for the current invoice and payment status.

Resolve billing restrictions

If billing blocks a generation, open Billing and follow the payment instructions. An organization owner or admin can pay an open invoice or update the payment method.

A receipt marked Usage prepayment is credited toward your usage bill. It is not a second charge for the same usage. Unused prepayments are refunded when your subscription ends. Contact support if a charge or billing restriction looks incorrect.

Estimating costs

Before you generate, you can see the estimated cost in the bottom right corner of the playground. You can also use our “Estimate cost” calculator on our pricing page to forecast your bills.

const response = await fetch("https://api.sync.so/v2/generations/estimate", {
    method: "POST",
    headers: {
        "x-api-key": process.env.SYNC_API_KEY!,
        "Content-Type": "application/json",
    },
    body: JSON.stringify({ model: "lipsync-2", duration: 10, fps: 30 }),
});
if (!response.ok) throw new Error(await response.text());
const estimate = await response.json();
console.log(`Estimated cost: $${estimate.estimatedGenerationCost}`);
console.log(`Estimated frames: ${estimate.estimatedFrameCount}`);
console.log(`Estimated credits: ${estimate.estimatedCredits}`);

Check a generation’s recorded cost

Use Get Generation Costs to read the recorded cost of a past generation. The response separates lip sync, dubbing, and speech synthesis where applicable. If a component is pending or unavailable, totalCostUsd is null; knownSubtotalUsd is only the known portion.

Usage-billed amounts exclude invoice adjustments and tax. Credit amounts use the credits’ face value of $0.01 each, which can differ from the cash price paid for those credits. Subscription fees, external provider charges, and account-level adjustments are excluded.

A refunded generation is marked refunded in your usage history. On usage billing, the charge returns as account credit for future invoices. The original charge remains visible.

Exporting usage data

You can export your usage records as a CSV from the billing page.

How to export:

1. Go to sync.so/billing/usage
2. Apply any filters (date range, API key, model, etc.)
3. Click the download button in the top-right

The export respects your current filters—if you’ve filtered to a specific API key or date range, only those records will be included.

What’s included:

The filename follows the format [team-name]-usage-[start-date]-to-[end-date].csv.

Payment & invoices

We use Stripe to process payments. If a payment fails, update your payment method on the Billing page and retry the payment.

Organization owners and admins can select Manage billing and payment methods on the subscription page to update saved payment methods.

To pay an outstanding invoice, find it under Open invoices on the same page and select Pay invoice. If you’re a member, ask an owner or admin to make the payment. If generation remains paused and no invoice is listed, contact support.

Cancellation

Monthly subscriptions renew automatically unless you cancel before the next renewal. You can cancel your subscription at any point without a cancellation fee. When you cancel, you keep access to the platform until the end of your current billing cycle. If you continue generating during this time, usage charges still apply.

How to cancel:

1. Log in to your sync.so account
2. Go to Billing in the left-hand sidebar
3. Click Cancel Subscription in the top-right corner of the Billing page
4. Complete the short feedback survey, then confirm your cancellation through Stripe

Refunds

We understand that circumstances change. Refund eligibility is based on your subscription tier and usage during the billing period.

Refund conditions by tier:

Important notes:

• Refunds apply only to the base price of your monthly subscription invoice, not usage invoices
• Frame usage is calculated based on the videos generated at the time of your refund request
• Refund requests must be submitted within the current billing period
• If you forgot to cancel and were charged, you are only eligible for a refund on your most recent subscription charge
• Processing of approved refunds typically takes 5–7 business days

If a full refund leaves every paid invoice on a self-serve subscription fully refunded, the subscription ends immediately and the account returns to the free plan. A partial refund does not automatically cancel the subscription. Contact your account team about refunds for negotiated or enterprise plans.

How to request a refund:

1. Go to sync.so/billing/subscription
2. Click Manage billing and payment methods
3. You’ll be redirected to Stripe where you can see Cancel + refund options
4. Follow the prompts to submit your refund request

If you no longer have access to your subscription for any reason, contact our support team and we’ll assist you with the refund process.
