Why Does My WooCommerce Renewal Show a $0 Total?
Why This Happens
WooCommerce Subscriptions' coupon system distinguishes between discounts that apply once (to the initial order only) and discounts explicitly configured to apply to every recurring payment. A coupon set up as a 100% recurring discount will correctly zero out every renewal for as long as it's applied — this is a legitimate, if unusual, promotional setup (a permanently free tier unlocked by a specific code, for instance), not automatically a bug.
Common Causes
- Coupon deliberately configured as a recurring 100% discount — confirm this is actually the intended behavior before treating it as a problem.
- Coupon meant to be one-time, but configured with the recurring discount type by mistake — the specific setup error covered in the general coupon troubleshooting question.
- A discount stacking issue, where a smaller intended discount combines with another coupon or an automatic promotion to unintentionally reach 100% off.
- A custom pricing plugin interacting unexpectedly with the coupon calculation, producing a $0 total that isn't actually coming from the coupon's own configuration at all.
How to Fix It
- Check the coupon's discount type and percentage directly under WooCommerce → Coupons, confirming it matches what was actually intended.
- If it's a one-time coupon incorrectly set to recurring, correct the discount type — existing subscriptions that already renewed at $0 under the wrong configuration may need a manual correction to their next payment amount.
- If multiple discounts are stacking unexpectedly, review whether that combination should actually be allowed, and adjust coupon restrictions if not.
- If a $0 renewal is genuinely intended (a legitimate permanently-free promotional tier), that's not a bug at all — just confirm accounting/reporting correctly reflects $0 revenue on those specific renewals rather than treating it as an error to chase.
