Billing & Credits
Plans, credit quotas, overage rates, spending caps, data retention, and support tiers
Rills charges for actions, not for orchestration. Two credit types -- Workflow Credits and AI Credits -- are included with every plan. Logic, approvals, and paused workflows are free.
Plans
| Plan | Price | Workflow Credits/mo | AI Credits/mo | Team members |
|---|---|---|---|---|
| Hobby | $29/month | 10,000 | 100 | 1 |
| Professional | $99/month | 50,000 | 750 | 5 |
| Business | $349/month | 200,000 | 3,500 | 25 |
| Enterprise | Custom | 1,000,000+ | Custom | Unlimited |
The Hobby plan includes a 14-day free trial. Credits do not roll over. See the pricing page for the full plan comparison.
Changing plans
When you upgrade or downgrade, both your included credits and spending cap reset to the new tier's defaults immediately. For example, upgrading from Hobby to Professional changes your included Workflow Credits from 10,000 to 50,000 and your spending cap from $14.50 to $49.50.
The change takes effect at the time of the product change, not at the next billing cycle. Workflows that are already executing are not interrupted by a plan change.
Billing cycle
Billing is monthly, anchored to the day you subscribed. Each period runs from your period start date to your period end date, and credits reset at the start of each new period. Credits do not roll over between billing periods.
Invoices and receipts are managed by Polar (our merchant of record) and accessible through the Polar customer portal linked from your billing settings.
Payment failures
If a payment fails, there is a 3-day grace period. During that window, workflows continue running normally.
If payment is not resolved within 3 days, all active workflows in the workspace are paused with status paused_billing_lapse. Resolving the payment (successful retry or updated payment method) automatically resumes paused workflows -- no manual restart needed.
What costs credits
Workflow Credits
Consumed by operations that interact with external systems or execute custom code:
- External API calls -- 1-3 Workflow Credits per call
- Custom code execution -- 5 Workflow Credits per run
- File operations -- 1-5 Workflow Credits depending on file size
- Scheduled trigger checks -- 0.1 Workflow Credits per check
AI Credits
Consumed by AI model calls. Cost varies by model and token count, typically 2-5 AI Credits per call.
What's free
- Logic and conditionals
- Human approvals
- Paused workflows
- Dashboard and monitoring
- Integration connections
- Test runs without external calls
Overage pricing
When you exceed your included monthly quotas, additional usage is charged at the following overage rates:
| Plan | Workflow Credits | AI Credits |
|---|---|---|
| Hobby | $1.50 per 1,000 | $3.00 per 100 |
| Professional | $1.00 per 1,000 | $3.00 per 100 |
| Business | $0.75 per 1,000 | $3.00 per 100 |
| Enterprise | Based on volume | Based on volume |
Higher-tier plans have lower per-unit overage rates for Workflow Credits.
How overages are calculated
Overages are calculated per billing period. Usage above your included quota is multiplied by your tier's per-unit overage rate.
Each credit consumption creates an immutable ledger entry recording the operation type (API call, AI generation, etc.) and execution context (which workflow, which step). Spending caps (see below) prevent runaway costs by pausing workflows when the cap is reached. The ledger serves as the source of truth for any usage questions.
Spending caps
Each plan includes a default spending cap set to 50% of the subscription price:
- Hobby: $14.50
- Professional: $49.50
- Business: $174.50
- Enterprise: Custom
When the cap is reached, workflows that would consume additional credits pause. They resume when you raise the cap or the next billing cycle starts. You can adjust your spending cap in billing settings.
How enforcement works
The spending cap is checked before every billable operation -- each Workflow Credit or AI Credit consumption. When current overage spending reaches or exceeds the cap, all active workflows in the workspace are paused with status paused_credits_exhausted.
An already-running step completes, but the next billable step will not start. This means a single operation may push spending slightly past the cap, but no further billable work begins.
Raising the cap (or starting a new billing cycle) automatically resumes all paused workflows. No manual restart is needed.
Usage alerts
Automated email alerts are sent at two thresholds:
- 80% -- warning that you are approaching your included quota
- 100% -- notification that your included credits are exhausted and overage billing has started
Alerts are tracked independently for Workflow Credits and AI Credits. You may receive a Workflow Credit warning while your AI Credits are still well within quota.
Each threshold sends only one alert per billing period -- no repeated notifications. Alerts are sent to the workspace owner's email address.
Data retention
Execution logs, step-level input/output data, and workflow run history are retained based on your plan:
- Hobby: 7 days
- Professional: 14 days
- Business: 30 days
- Enterprise: Custom
After the retention period, execution data is deleted. Workflow configurations -- the workflows themselves -- are not affected.
What retention covers
Retained (subject to your plan's retention period):
- Execution logs
- Step-level input/output data
- Workflow run history
- Webhook request logs
Audit logs have 2x the standard retention period (e.g., 14 days on Hobby, 28 days on Professional).
Not affected by retention (persisted indefinitely):
- Workflow definitions and configurations
- Integration configurations
- Billing history
Retention is configurable per workflow, overriding the workspace default set by your plan tier.
Support tiers
- Hobby: Community support
- Professional: Email support (24-hour response)
- Business: Priority support (12-hour response)
- Enterprise: Custom SLA
Managing costs
- Start with high auto-approval thresholds so workflows ask before spending credits on uncertain actions.
- Use free logic and conditionals instead of AI calls where pattern matching or branching suffices.
- Archive unused scheduled workflows -- trigger checks cost Workflow Credits even when workflows do not proceed.
- Set budget alerts to get notified before reaching your spending cap.
- Review usage patterns monthly to identify workflows with unexpectedly high credit consumption.
Viewing your usage
Navigate to Settings > Usage in your workspace to see real-time credit consumption:
- Free counters show approval and logic step counts. These operations are free and unlimited -- the counters are there so you can see how much orchestration Rills handles at no cost.
- Credit meters show Workflow Credits and AI Credits usage: used, limit, and remaining for the current billing period.
- Billing period dates are displayed at the top so you know when credits reset.
- Per-workflow breakdown table shows which workflows consumed the most credits, helping you identify where to optimize.
