Billing and Usage

Understand Symbi's billing model, manage your credit balance, and keep costs under control.

How Billing Works

Symbi uses a hybrid billing model that combines a base subscription with metered credits for AI usage. Your monthly plan includes a credit allocation, and each AI interaction consumes credits based on the complexity of the task.

View and manage all billing details from Settings → Billing.

Credit System

Credits are the currency that powers your agents and Personal Assistants. Here's how they work:

  • Monthly allocation — your plan includes a set number of credits each billing cycle
  • Per-interaction consumption — each time an agent or Personal Assistant processes a task, credits are deducted based on complexity
  • Hard cap toggle — when enabled, processing stops once credits run out, preventing overage charges
  • Overage billing — if the hard cap is off, your agents continue working beyond the allocation and additional usage is billed at a per-credit rate

Warning

When hard cap is enabled, agents and Personal Assistants stop processing new tasks once credits are exhausted, until the next billing cycle. Make sure your allocation covers your expected volume.

Usage Breakdown

The billing page shows a per-agent breakdown of credit consumption, plus usage from your team's Personal Assistants. Use it to:

  • Identify high-volume agents that may benefit from knowledge base tuning
  • Spot unexpected spikes in usage
  • Compare credit consumption across agents handling similar workloads

Transaction and Invoice History

Symbi keeps a complete log of all credit activity:

  • Transaction history — every credit allocation, consumption event, and adjustment, with timestamps and details
  • Invoice history — past invoices are available for download directly from the billing page

Managing Your Subscription

Click Manage Subscription to open the Stripe Customer Portal, where you can:

  • Update your payment method
  • View and download invoices
  • Change your plan or billing cycle
  • Cancel or modify your subscription

All subscription management is handled securely through Stripe.

Cost Management Tips

Getting the most out of your credits takes a bit of strategy:

  • Use review mode wisely — declined actions still consume credits. Start with Always Review to build a high approval rate before scaling
  • Keep knowledge bases focused — smaller, well-curated bases cost less to process than large, unfocused collections
  • Monitor per-agent usage — check the breakdown regularly to spot agents that could benefit from tuning
  • Enable hard cap for strict budgets — if you need predictable costs, turn on the hard cap to never exceed your allocation
