Bill Customers on Time Without Manual Intervention
Late or missed invoices hurt cash flow and damage client relationships. CronJobPro triggers your billing pipeline on schedule, ensuring invoices are generated, sent, and tracked without anyone remembering to click a button.
Manual Billing Is Slow, Error-Prone, and Unreliable
The accounts receivable team spends days each month generating invoices, cross-referencing orders, and chasing payments. Mistakes slip through, invoices go out late, and cash flow suffers.
- ✗Invoices go out a week late because the billing person is overloaded with other tasks
- ✗Manual invoice generation leads to calculation errors and missing line items
- ✗No reliable system to retry failed invoice sends or track which invoices bounced
- ✗Month-end billing crunch creates bottlenecks that delay financial reporting
Billing Runs That Execute Like Clockwork
CronJobPro triggers your invoice processing endpoint on a defined schedule. Whether you bill daily, weekly, or monthly, the system generates invoices, sends them, and logs every step — with alerts when anything fails.
Automatic Retries
If your billing endpoint fails due to a database timeout or payment gateway issue, CronJobPro retries automatically — ensuring no invoice goes unsent.
Execution Logs
Every billing run is logged with timestamps, record counts, and status codes — providing a complete audit trail for your finance team.
HMAC Signing
Secure your billing endpoint with HMAC signatures so only verified CronJobPro requests can trigger invoice generation.
How to Set It Up
- 1
Build an invoice generation endpoint
Create an HTTP endpoint that queries billable items, generates invoices, sends them via email or payment platform, and returns a success or failure status.
- 2
Schedule the billing run in CronJobPro
Set the cron schedule to match your billing cycle — daily for usage-based billing, monthly for subscription invoices.
- 3
Secure the endpoint with HMAC signing
Enable HMAC webhook signing so your billing endpoint verifies that each trigger comes from CronJobPro, not an unauthorized source.
- 4
Configure alerts for billing failures
Failed billing runs directly impact revenue. Set up email and Slack alerts to notify your finance team immediately if a billing run fails.

Frequently Asked Questions
How do I prevent duplicate invoices if CronJobPro retries?
Design your billing endpoint to be idempotent. Check whether invoices for the current period already exist before generating new ones. Return success if they do.
Can I handle different billing cycles for different customers?
Yes. Create separate cron jobs for each billing cycle — one for monthly subscribers, one for annual, one for usage-based. Each triggers the same endpoint with different parameters.
What happens if the payment gateway is down during a billing run?
CronJobPro retries with exponential backoff. If the gateway remains down through all retries, your finance team is alerted to manually process the failed batch.
Can I generate invoices in multiple currencies?
Your billing endpoint handles currency logic. CronJobPro triggers the process — you can pass currency parameters in the request body or let your endpoint determine currency per customer.
