Choosing the right software
Distinguish software for running your own referral program from membership in a merchant affiliate network. Define attribution windows, refund adjustments and payout review before choosing tracking tools. Test duplicate referrals and cancelled orders. Installing a plugin does not authorize affiliate links or payouts; merchant agreements and financial arrangements remain separate.
This shortlist covers 4 currently listed WordPress options selected from 4 catalog records with supported evidence for this use case. Each included record has an official directory URL, a recent metadata check and a recorded upstream update within two years. The selection prioritizes a matching stated purpose, then reported adoption as a tie-breaker. It is not a hands-on performance ranking or a security endorsement. The snapshot was prepared on 2026-10-02.

Compatibility comparison: 3 distinct prerequisite statements are recorded across this shortlist. WordPress 6.0 / PHP 7.3; WordPress 4.6 / PHP; WordPress 6.5 / PHP 7.4. Match these minimum requirements to your actual PHP and WordPress versions, then test the specific workflow on a copy of your site. A minimum version is not a promise that every theme, extension or newer runtime combination works. Missing integration evidence should remain a question for the developer.
Free here refers only to the authorized core code download linked from the WordPress directory. Premium editions, external API usage, hosting, support and migration work may have separate costs. No commercial price, discount, unlimited service allowance or free paid edition is inferred. Follow the official route and review edition limits before treating a core feature as part of your project budget.
