Billing

What happens when I upgrade to the Developer tier?

When you upgrade, there is no immediate charge. You are billed for usage at month end or when you reach progressive billing thresholds, which are listed below.

Usage is based on the source audio or video duration for each generation, rounded up to the next whole second, with a minimum billable duration of 60 seconds per generation.

Example: generating from 30 seconds of media bills 60 seconds. From 80 seconds, it bills 80 seconds; from 80.2 seconds, it bills 81 seconds. Each additional generation of the same media is metered separately. The model rate is applied to the billable seconds, and the cost is rounded up to the next whole cent. See the API pricing page for current model rates.

To upgrade from the Free tier to the Developer tier, add a valid payment method, including a credit card, a United States bank account, or a SEPA debit account.

Your upgrade takes effect immediately. Billing occurs at the end of your monthly billing cycle or when you cross the progressive thresholds of $1, $10, $100, $500, and $1,000.

What are the benefits of upgrading?

The Developer tier is designed for developers and teams who need more capacity with pay as you go pricing.

• Usage based billing for production workloads
• Monthly spend limits per API key
• Audit logs with 7 day retention

How do I downgrade or cancel?

App and API billing are separate. For your app subscription, open Profile and select Manage App Billing. Review the available changes and their effective dates in the billing portal before confirming.

For API billing, open Billing and select Manage billing, or select Manage API Billing on Profile to manage payment details. To request an API downgrade or cancellation, contact support@diffio.ai to confirm the account change, its effective date, and any outstanding usage charges.

How does the billing cycle work?

Diffio uses a monthly billing cycle. You receive an invoice in arrears for usage. New Developer tier accounts also follow progressive billing thresholds to ease into pay as you go usage.

How does progressive billing work?

During the progressive billing phase, an invoice is triggered and payment is deducted when your cumulative usage reaches $1, $10, $100, $500, and $1,000.

Special billing for customers in India

Customers with a billing address in India have different thresholds. For India customers, the thresholds are $1, $10, and then every $100 thereafter. The $500 and $1,000 thresholds do not apply.

These thresholds are one time for most customers. Once you cross the $1,000 lifetime usage threshold, only monthly billing continues. For India customers, billing continues at each $100 increment.

What if I do not reach the next threshold?

If you do not reach the next threshold, your usage is billed on your regular end of month invoice.

Example

• You cross $1, you are charged immediately.
• You then use $2 more for the month. Lifetime usage is $3, still below $10.
• The $2 is invoiced at the end of your monthly billing cycle, not immediately.

When is payment withdrawn from my account?

Payment is withdrawn automatically from your connected payment method each time an invoice is issued. This can happen during the progressive billing phase or at the end of each monthly billing cycle.

We only bill you once your usage reaches at least $0.50. If you see a total charge under $0.50, there is no action required on your end.

How can I view my current usage and spending in near real time?

You can monitor usage in the Diffio dashboard. Visit the Usage page to track usage across models and see how consumption aligns with pricing.

Can I set spending limits?

Yes. Set a monthly spend limit when creating or editing a key on the API keys page. Limits apply to individual API keys.

Where can I find my past invoices and payment history?

Open the Billing page to review API invoices. Select Open on an invoice to view its hosted invoice page, or Details for its usage breakdown. For app subscription billing, open Profile and select Manage App Billing.

Can I change my billing info and payment method?

For API billing, open Billing and select Manage billing, or open Profile and select Manage API Billing. For app subscription billing, select Manage App Billing on Profile. These controls open the billing portal.

What payment methods do you accept?

Diffio accepts credit cards (Visa, MasterCard, American Express, Discover), United States bank accounts, and SEPA debit accounts.

Are there promotional credits or trial offers?

New API Developer upgrades receive a one time $5 usage credit after you add a payment method. The credit applies to future API invoices once checkout completes.

How are refunds handled, if applicable?

Refunds are handled on a case by case basis. Contact our support team at support@diffio.ai for assistance.

What if I believe there is an error in my bill?

Check your Usage and Billing pages first. If you still believe there is an issue, contact support at support@diffio.ai.

Under what conditions can my account be suspended due to billing issues?

Account suspension or restriction can occur after prolonged non payment or consistently failed payment attempts. We handle each case individually. If your account is impacted, contact support for guidance.

What happens if my payment fails?

Update your payment method to ensure successful processing. We may retry payments, and failed payments can result in service suspension. We will email you if an invoice is unpaid.
