What is required.
WHAT YOU NEED
A gateway supporting recurring payments Subscription software on your site A process for failed payments Customer-facing subscription management
THE GATEWAY QUESTION
Not every gateway supports recurring billing, and support varies by country.
Confirm before building anything.
HOW RECURRING BILLING WORKS
The customer authorises future charges at signup.
Your system or the gateway charges on schedule.
TWO APPROACHES
The gateway manages the subscription and charges automatically Your site initiates each charge using a stored authorisation
Which applies depends on your gateway and plugin.
WHAT TO CHECK
Whether the gateway or your site is the source of truth for subscription status.
Confusion there causes billing failures.
WHAT TO TEST
A full cycle, including a renewal.
That usually means waiting, or using test mode with a shortened interval.
WHAT MOST PEOPLE SKIP
Testing the renewal. That is the part that fails.
