Billing
How it works
Sync uses a subscription + usage model. Your subscription unlocks higher limits, premium features, and discounts, while you pay for what you generate.
Free trial
New to sync? Every free account gets 3 free generations per month on any lipsync family model (including lipsync-2 pro) plus 10 text-to-speech generations, with a maximum video duration of 20 seconds per generation. No credit card required.
This is a great way to explore sync and test our models before committing to a plan.
Free generations are only available on free accounts. Once you subscribe, you move to usage-based billing; there’s no monthly free generation allowance on paid plans.
Subscriptions
When you subscribe, you unlock higher concurrency, longer video durations, premium features (such as “Reasoning mode”, “Automatic Speaker Detection”, “Team workspaces”, etc.), access to all models (including react-1), and usage discounts on higher tiers.
Once subscribed, you pay for what you use. No credits, no prepayment — just generate and pay for what you use.
See our pricing page for plan details and model rates.
Usage billing
You’re billed based on what you generate. We calculate usage by taking the frames from your output video at 25 fps and multiplying by the per-frame price for the model you used. Each model has different rates—see our pricing page for details.
How usage invoices work:
Your usage accumulates until it hits your tier’s threshold, at which point an invoice is automatically generated and your card is charged.
For example, if you’re on the Creator plan and your usage reaches $20, an invoice is created and charged to your card automatically.
If a usage invoice goes unpaid, generations are blocked until the invoice clears.
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.
Payment & invoices
We use Stripe to process payments. If a charge fails, Stripe will retry for 5 days. If payment still fails after 5 days, your subscription will be automatically cancelled.
Keep your payment method up to date to avoid interruptions.
Cancellation
You can cancel your subscription at any point without additional fees. 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 and will be billed when thresholds are reached.
How to cancel:
- Log in to your sync.so account
- Go to Billing in the left-hand sidebar
- Click Cancel Subscription in the top-right corner of the Billing page
- Follow the on-screen prompts to confirm
Canceling your subscription stops future billing but does not refund past charges. For refunds, see below.
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
How to request a refund:
- Go to sync.so/billing/subscription
- Click Manage billing
- You’ll be redirected to Stripe where you can see Cancel + refund options
- 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.

FAQ
Why am I charged both a subscription fee and usage fees?
Your subscription unlocks platform features like higher concurrency, longer video durations, and watermark removal (Creator+). Usage fees are separate—you pay for each generation based on the model and output duration.
Does my subscription include credits for video generation?
No. Your subscription fee covers platform access and feature unlocks. Video generations are billed separately based on usage.
How many videos can I create with my subscription?
There’s no limit on the number of videos. Your subscription unlocks capabilities (concurrency, max duration, etc.), and each generation is charged based on output frames.
Why was I charged multiple times this month?
Usage charges accumulate as you generate. Each time your usage hits your tier’s threshold, an invoice is automatically created and charged. If you generate a lot, you may hit the threshold multiple times in a month.
I paid for a subscription but can't generate videos—why?
If you have an unpaid usage invoice, generations are blocked until it clears. Check your billing settings in the dashboard to see if there’s an outstanding invoice warning.
What does my subscription fee cover vs. usage fees?
Subscription covers platform access, concurrency limits, max video duration, watermark removal (Creator+), and access to subscription-only models like react-1. Usage fees cover the actual compute cost of each generation.
Why do my videos have a watermark?
Watermarks are removed on Creator plans and above. Hobbyist and free accounts will see a sync watermark on generated videos.
How is usage calculated?
We take the frames from your output video at 25fps and multiply by the per-frame price for the model you used. Different models have different rates—check our pricing page for details.
I was charged but my usage shows a different amount—why?
Usage shown in the dashboard is real-time, while invoices are generated when thresholds are hit. There may be a small delay between usage accruing and the invoice being created. If something looks off, reach out to support.
Can I pay only for usage without a subscription?
No. To unlock usage-based billing, you need to subscribe to one of our plans. Free accounts get 3 generations per month but can’t pay for additional usage without subscribing.
What happens when I cancel my subscription?
Cancellation takes effect at the end of your billing cycle—you keep access until then. If you generate during this period, usage charges still apply and will be billed at the normal thresholds.
