Three plugins handle self-hosted affiliate programs on WordPress better than anything else: AffiliateWP, SliceWP, and Solid Affiliate. All three track referral clicks, record commissions, and pay affiliates. The differences come down to price, WooCommerce integration depth, and how complex your commission structure needs to be.
AffiliateWP
AffiliateWP has been around since 2014 and has the largest install base of the three. Its main advantage is the addon library – if you need something specific (multi-tier commissions, recurring referrals on subscriptions, per-product commission rates, affiliate leaderboards), there is an AffiliateWP addon for it. The base plugin handles registration, link generation, click tracking, and payouts. The addons extend it for complex programs.
Pricing is per year per site: $149 (Personal, most addons excluded), $249 (Professional, most addons included), $299 (full, everything). If you need coupon tracking or recurring referrals – which most WooCommerce stores eventually do – you need Professional at minimum.
SliceWP
SliceWP is the lowest-cost option with a free tier that actually works for simple programs. The free version covers WooCommerce and Easy Digital Downloads integration, referral tracking, and a basic affiliate dashboard. Pro ($69/year) adds PayPal payouts, coupon tracking, and email notifications – the features most programs need within a few months of launching.
What SliceWP does not have: multi-tier commissions, recurring referral tracking on subscriptions, or the depth of integrations AffiliateWP provides. For a straightforward WooCommerce affiliate program without complex requirements, SliceWP Pro is $80/year cheaper than AffiliateWP Personal and covers the same ground.
Solid Affiliate
Solid Affiliate is built specifically for WooCommerce. Coupon code affiliate tracking is included in the base price – affiliates get commission when a customer uses their coupon code at checkout, regardless of whether a referral link was clicked. This matters for influencer programs where a discount code (“use SARAH20 for 20% off”) drives more purchases than a tracked link.
Pricing: $149/year (1 site) or $199/year (unlimited sites). The unlimited plan is good value for agencies managing multiple client stores.

The Honest Recommendation
Start with SliceWP free if you want to test whether an affiliate program generates any revenue before spending money. Move to SliceWP Pro ($69/year) when you need payouts and coupon tracking.
Choose Solid Affiliate if your program is WooCommerce-focused and influencer coupon campaigns are part of your strategy. The built-in coupon tracking at $149/year makes more sense than AffiliateWP Personal ($149/year) without coupon tracking.
Choose AffiliateWP Professional ($249/year) if you sell subscriptions and need recurring referral tracking, or if you need multi-tier commissions, or if you have multiple non-WooCommerce integrations to cover.
