Billing Cycles

Horizon subscriptions are billed on a monthly or annual basis:

• Monthly billing — charged on the same day each month (the day you first subscribed). Cancel anytime with no long-term commitment.
• Annual billing — charged once per year. Annual plans receive a 20% discount compared to monthly billing. Annual subscriptions are non-refundable but you can upgrade at any time during the cycle.

Tip

If you are confident in your Horizon usage, annual billing provides significant savings. You can start monthly to evaluate the platform and switch to annual when ready.

Your subscription fee covers the plan’s base features and user seats. Credit purchases for agent activity (LLM calls, skill executions) are billed separately through the Wallet system.

Upgrading Your Plan

1. Navigate to Billing > Subscriptions.
2. Click Change Plan.
3. Select the new plan tier.
4. Review the feature changes and updated pricing.
5. Confirm the upgrade.

Upgrades take effect immediately:

• New features and higher limits are available right away.
• You are charged a prorated amount for the remainder of the current billing cycle.
• If you are on annual billing, the prorated difference between the old and new plan is charged immediately.

Note

When upgrading from Starter to Professional, existing agents and connections are preserved. You can immediately begin using new features like custom roles and partner management.

Downgrading Your Plan

Downgrades take effect at the end of your current billing cycle. This means:

• You continue to have access to your current plan’s features until the cycle ends.
• At the start of the next cycle, the lower plan’s limits take effect.

Before the downgrade applies, Horizon checks whether your current usage fits within the lower plan’s limits. If not, you will see warnings about what needs to change:

Overage	Action Required
Too many users	Deactivate users to meet the new plan’s limit
Too many agents	Pause or delete agents to fit the new limit
Too many connections	Remove connections to fit the new limit
Too many departments	Consolidate or remove departments

If overages are not resolved before the downgrade date, the system will automatically pause resources that exceed the new limits — starting with the most recently created ones.

Caution

Review your usage carefully before confirming a downgrade. Automatic pausing of resources can disrupt running workflows and agent operations.

Enterprise Plan Setup

The Enterprise plan requires a conversation with the Horizon sales team due to its custom pricing and configuration options.

1. Navigate to Billing > Subscriptions.
2. Click Contact Sales on the Enterprise plan card.
3. Fill out the inquiry form with your organization size, expected usage, and specific requirements.
4. A Horizon account executive will schedule a call within 1 business day.
5. After agreement on terms, the Enterprise plan is activated on your account.

Enterprise contracts are typically annual with custom payment terms (net-30, net-60, etc.).

Invoices

All billing events generate invoices accessible from Billing > Subscriptions > Invoices:

• Subscription invoices — generated at the start of each billing cycle.
• Credit purchase invoices — generated each time you add funds to your wallet.
• Prorated invoices — generated when you upgrade mid-cycle.

Each invoice includes:

• Invoice number and date.
• Line items with descriptions and amounts.
• Tax details (if applicable based on your billing address).
• Payment status (Paid, Pending, Failed).
• A downloadable PDF.

Billing Information

Update your billing details under Billing > Subscriptions > Billing Info:

• Billing email — the address that receives invoices and payment receipts.
• Company name — the name that appears on invoices.
• Billing address — used for tax calculation.
• Tax ID — your VAT, GST, or EIN number (optional, included on invoices if provided).

Payment Methods

Horizon accepts the following payment methods:

• Credit card — Visa, Mastercard, American Express. Cards are stored securely via Stripe.
• ACH bank transfer — available for US-based organizations on Professional and Enterprise plans.

Cancellation

To cancel your Horizon subscription:

1. Navigate to Billing > Subscriptions.
2. Click Cancel Subscription.
3. Select a reason for cancellation (optional but appreciated).
4. Review the cancellation terms:
   • Monthly plans: access continues until the end of the current billing period.
   • Annual plans: access continues until the end of the annual term. No partial refunds.
5. Confirm cancellation.

After cancellation takes effect:

• All running agents are stopped.
• Your data is retained for 30 days in case you resubscribe.
