Billing & Plans
How pricing works
Zapat uses a prepaid balance model. Understand per-issue costs, budget controls, and how billing works.
Updated March 3, 2026
Zapat uses a simple pay-per-issue model with a prepaid balance. You top up your balance via Stripe, and each issue deducts from your balance based on actual AI costs with a 3x markup — with configurable per-issue budget limits. Most issues cost $6–12. New accounts get $15 in compute credits, no credit card required. Refer friends — you both get $5 per referral, up to $15 more.
What counts as an issue
Billing is based on actual AI usage per job, with a 3x markup on the underlying model cost. Each issue lifecycle (all jobs for one issue) is subject to a per-issue budget you configure. Specifically:
- Each pipeline stage (triage, implement, test, review) is a separate job with its own cost.
- Cost is calculated as: actual AI model cost x 3, subject to your per-issue budget limit.
- Rework cycles add to the lifecycle cost, but the per-issue budget still applies.
- Failed jobs that consumed AI tokens are charged for the work attempted.
- Jobs blocked by zero balance enter "pending funds" state and resume when you top up.
Average cost per issue
Most issues cost $6–12. Simple bug fixes and triage may cost $2–4, while complex multi-file features with test generation may cost more. You set a per-issue budget so you never get a surprise bill.
Viewing your usage
- Go to Billing in the dashboard to see your current balance and transaction history.
- Go to Usage to see: issues processed, total cost, success rate, and a breakdown by trigger type.
- Each job shows its individual cost in the Jobs list.
- You receive a notification when your balance is running low.
What happens when you hit your limit
When your balance reaches $0, new billable jobs (triage, implement, research, write-tests) enter a "pending funds" state instead of being dispatched. Any jobs currently running will complete normally. You will receive a notification. Top up your balance via Stripe to resume — pending jobs will automatically dispatch once funds are available. You can also enable auto-recharge to prevent interruptions.
