Deploying new code to a standard ecommerce site is straightforward. You test on staging, push to production, clear the cache, and you are done.

Deploying to a site running WooCommerce Subscriptions is a completely different operation. Because WooCommerce Subscriptions relies on WordPress cronjobs to trigger recurring payments, your live environment is constantly processing renewals in the background. If you deploy code that interrupts a cronjob, or if your staging environment accidentally triggers live renewals, the consequences are severe: double-charged customers, missed renewals, or corrupted subscription data.

As an agency that has built and maintained some of the fastest-growing subscription businesses on WooCommerce, we have seen every edge case.

Here is the exact deploy checklist you need to follow to safely push updates to a WooCommerce Subscriptions site — and how a headless Stripe setup changes the process entirely.

The Pre-Deploy Checklist (Staging Environment)

Before you push any code to production, you need to ensure your staging environment is safe. The biggest risk in subscription development is a staging site accidentally triggering live payments or sending renewal emails to real customers.

1. Disable Action Scheduler and Cronjobs on Staging
The moment you clone your production database to staging, you copy over all scheduled renewals. If cron runs on staging, it will attempt to process those renewals. You must disable the Action Scheduler or define DISABLE_WP_CRON as true in your wp-config.php immediately.

2. Reroute or Disable Emails
If a renewal does process on staging, you do not want the customer receiving an email receipt. Use a plugin like WP Mail SMTP to reroute all outgoing staging emails to a catch-all address, or disable emails entirely.

3. Switch Payment Gateways to Test Mode
Ensure your Stripe or PayPal gateways on the staging site are strictly in Test Mode. If they remain in Live Mode and a renewal is triggered, real money will be captured.

4. Test the Subscription Lifecycle
Do not just test the frontend. Manually trigger a renewal using the Action Scheduler interface to ensure your new code has not broken the subscription engine. Test a failed payment, a successful renewal, and a cancellation.

The Production Deploy Checklist

When staging is verified, you are ready to deploy to production. Because production is constantly processing renewals, timing and execution are critical.

1. Check the Action Scheduler Queue
Before you begin the deploy, go to WooCommerce > Status > Scheduled Actions. Check the "Pending" queue. If there is a large batch of renewals scheduled to run in the next five minutes, wait. Deploying while a large batch of renewals is processing increases the risk of database locks or incomplete transactions.

2. Put the Site in Maintenance Mode
To prevent new subscriptions from being created during the deploy, activate a maintenance mode plugin. This ensures database consistency while files are being updated.

3. Pause WP-Cron (Optional but Recommended for Major Updates)
If you are deploying a major update to WooCommerce or the Subscriptions plugin itself, it is safer to temporarily pause WP-Cron to ensure no renewals trigger while files are being overwritten.

4. Deploy Code and Run Database Updates
Push your code. If the deploy includes an update to the WooCommerce Subscriptions plugin, you must log in to the WordPress admin immediately and click the "Update WooCommerce Database" prompt. Subscriptions will not function correctly until the database schema matches the plugin version.

5. Verify the Action Scheduler
Once the deploy is complete and maintenance mode is lifted, return to WooCommerce > Status > Scheduled Actions. Verify that the "Complete" queue is updating and that the "Failed" queue is not suddenly filling up with errors.

6. Monitor Stripe Webhooks
Log in to your Stripe dashboard and check the Developer > Webhooks section. Ensure that webhook events from WooCommerce are returning a 200 OK status. If they are returning 500 errors, your deploy has broken the endpoint that Stripe uses to communicate with WooCommerce.
