How referral program runs on WordPress
The same recipe everywhere. Here is the path a referral takes through WordPress.
A customer refers
They share a personal referral link or code with a friend or business contact.
The friend buys
The sale completes natively on your WordPress site, with no redirect and no middleman.
Siren attributes it
The referring customer is credited the moment the referred order completes.
The reward is paid
As store credit on Lite and Essentials, or real money via Stripe Connect on Plus.
What is specific to WordPress

Pay a fixed reward per successful referral, as store credit they redeem at checkout or real money on Plus.

Referral program on WordPress questions answered
Is there a free WordPress referral plugin?
Yes. Siren Lite is free and runs link-based referral programs on your WordPress site. Upgrade to Essentials for coupon tracking and more reward shapes, or Plus for automatic real-money payouts.
How is a referral program different from an affiliate program?
Same engine, different audience. A referral program rewards your existing customers for referring friends, usually with a flat credit, while an affiliate program recruits external promoters who earn a commission. Siren runs both on the same site.
Can I reward referrals with store credit instead of cash?
Yes. On Lite and Essentials, referral rewards are issued as store credit that the referrer redeems at checkout. Real-money payouts via Stripe Connect are available on the Plus tier.
Can I run a B2B referral program too?
Yes. For business referrals, the B2B Referral Program recipe pays a flat bounty per referred sale with first-touch attribution, built for partnerships where each conversion carries significant value.
How are referrals tracked on WordPress?
By referral link or assigned code, with first or last-touch attribution. Siren records the referral natively on your site and credits the referrer the moment the referred order completes.
