Billing & Credits Overview

Understand the Fusion credit system — how credits work, what costs what, and how to manage spending.

Fusion uses a credit-based billing system. Credits are the currency for all platform actions — publishing quests, storing data, running experiments, and more.

How Credits Work

Concept	Value
1 credit	1 cent
Starter bonus	Free credits for every new organization

Credits are managed at the organization level. Every action that costs credits is charged to the organization that owns the quest. See the Pricing page for current credit values and costs.

What Costs Credits

The following actions consume credits from your organization’s balance:

Action	Category
Publish a quest	Quest & Experiments
Participant joins a quest	Quest & Experiments
Experiment data submission	Quest & Experiments
Brain recording (EEG)	Data Collection
Prompt response stored	Data Collection
Health data sync (wearable)	Data Collection
Dataset storage	Storage
AI data analysis	Analysis & AI
Analysis script execution	Analysis & AI

For current prices, see the Pricing page.

Free Actions

These actions are free and do not consume credits:

• Creating a quest (draft)
• Editing a quest
• Adding prompts and experiments
• Configuring onboarding
• Onboarding responses (no charge)
• Viewing data in the dashboard
• Adding organization members

Re-Publishing Is Free

The first time you publish a quest, it costs credits. Re-publishing the same quest (after unpublishing and making changes) is free — the system checks for a prior publish transaction.

Debt Tolerance

Some operations allow a small amount of debt to prevent data loss:

Action	Debt Allowed
Publishing a quest	❌ No — strict check, returns error if balance too low
Data collection (experiment, prompt, EEG, etc.)	✅ Yes — small debt allowed

Data collection actions never fail due to insufficient credits. The system allows a small amount of debt so participant data is never lost. Publishing, however, requires a sufficient balance.

Low Balance Warning

When your organization’s credit balance is running low, an amber warning appears on the dashboard:

“Your credit balance is running low. Add credits to continue using premium features.”
