Management and Tracking: How Each Tool Handles Program Operations

Refersion's first-party, cookieless tracking and managed payouts are mature and ecommerce-hardened. The trade-off is that everything lives in Refersion's cloud, and the richest tracking sits behind the Growth tier.

Pricing: Siren vs Refersion

Refersion and Siren use very different pricing models. Refersion charges a monthly subscription plus a percentage of your affiliate-driven sales: a free Marketplace Listing tier, then Launch at $39/mo ($29/mo annually) plus 3% of affiliate sales, Growth at $199/mo ($159/mo annually) plus 2%, and a custom Scale tier for brands past $1M GMV. The percentage means your bill grows as your program succeeds.

Siren is a WordPress plugin with flat annual pricing and no percentage cut of affiliate revenue. Feature gates that Refersion puts behind its $199/mo Growth tier (product-level commissions, API access, 30+ marketing integrations) are included on lower Siren plans, and Siren's data stays on your own server. For a growing WordPress program, Siren is usually far cheaper at scale. For a Shopify store, Refersion fits the platform better.

Free plan Siren: Yes. Siren Lite Refersion: Yes / limited
What the free plan includes Siren: Unlimited programs, affiliates, and conversions; referral links; coupon tracking; payout management; REST API access; core integrations Refersion: A free Marketplace Listing tier: a public listing in the Refersion Marketplace, one percent-of-sale offer, affiliate applications and review, and basic tracking. Running a full program requires a paid plan.
Paid plans Siren: From $229/year Refersion: From $39/mo + 3% of affiliate sales ($29/mo billed annually)
Best free-plan fit Siren: Starting a real affiliate or incentive program without paying upfront Refersion: Listing an offer in the Refersion Marketplace to be discovered by affiliates, before committing to a full program
Best paid-plan fit Siren: Expanding into advanced partner programs, recurring commissions, revenue splits, tiered rewards, performance bonuses, and advanced attribution Refersion: A Shopify or ecommerce brand that wants first-party tracking, a recruitment marketplace, and managed payouts, and accepts paying a percentage of affiliate sales

Connect Siren to the Systems Where Partner Actions Happen

Refersion connects to Shopify, BigCommerce, Adobe Commerce, and WooCommerce as a hosted layer. The Siren WordPress plugin tracks WooCommerce, EDD, LifterLMS, and form events natively; for non-WordPress stores, Siren Cloud (founding access) and Full-Service (available now) attribute Shopify, Stripe, and CRM sales through one engine via webhooks and the REST API.

Switching from Refersion to Siren

Moving to the Siren WordPress plugin is really a move onto WordPress: you rebuild your Refersion offers as Siren programs and re-attach tracking to your WordPress store. This plugin path pays off when WooCommerce or another WordPress commerce plugin is where you sell, or where you are headed. If you want to stay on Shopify, Stripe, or another non-WordPress stack, you do not migrate at all: Siren Cloud (founding access) and Full-Service (available now) attribute those sales through one engine via webhooks and the REST API instead.

  1. 1

    Check that WordPress is where you sell

    The Siren plugin reads WooCommerce, EDD, LifterLMS, and Gravity Forms events, so this plugin path needs one of those running on WordPress. If your catalog lives on Shopify, Shopify Plus, BigCommerce, or Adobe Commerce, Refersion connects to it natively today. Take the plugin migration only if you are on WordPress or moving your store to it; otherwise keep your store where it is and track those orders with Siren Cloud or Full-Service via webhooks and the REST API.

  2. 2

    Pull your Refersion data before you disconnect

    Export your affiliate roster, referral and coupon codes, every commission structure you run (percentage, flat, tiered, per-product), and your payout and 1099 tax records. Getting all of it in hand first keeps the rebuild clean.

  3. 3

    Rebuild each offer as a Siren program

    Turn every Refersion offer or campaign into a Siren program with its own rates and rules. Bring referral codes across as aliases so partner links keep resolving, and give influencer or ambassador offers their own program so their terms stay separate.

  4. 4

    Re-attach tracking to your WordPress store

    This is the largest piece of the move. Refersion attributed sales from your Shopify storefront, while Siren reads WooCommerce or EDD orders, coupon usage, and subscription renewals directly, and can also reward LMS completions or form submissions you could not track before.

  5. 5

    Decide how you will pay affiliates

    Refersion handled one-click managed payouts and 1099 forms for you. In Siren you approve payout records, and on the Plus plan you can pay collaborators automatically through a connected processor like Stripe, so settle on your method and tax process before you cut over.

  6. 6

    Verify attribution, then grow the program

    Run test orders and confirm that links, coupons, subscriptions, and order attribution all fire in Siren while Refersion is still live. Once the core affiliate program is solid, layer on the royalties, revenue share, and bonus pools Refersion never offered.

Common Questions

Do I need to switch from Refersion to use Siren?

Not necessarily. The Siren WordPress plugin runs on your WordPress site and tracks WooCommerce, Easy Digital Downloads, and LifterLMS events directly, keeping the whole program and its data on your own server. If your store is Shopify, BigCommerce, or Adobe Commerce, Refersion connects to it natively and its one-click integration is more established today. Siren still reaches those stores through two other editions: Siren Cloud, a fully hosted engine that attributes sales from any channel via webhooks and the REST API (self-serve is in founding access, launching soon), and Full-Service, a managed edition available now that the Siren team runs on top of your existing stack. So a non-WordPress store can run Siren; the plugin specifically is what needs WordPress.

Can I migrate my affiliates and referral history from Refersion?

If you are moving onto WordPress, yes. Refersion affiliates become Siren collaborators, and their referral codes can carry over as aliases so existing links keep working. Commission rules are rebuilt as Siren programs, and historical commission and payout records can be imported for reference. The real work is re-pointing tracking: Refersion tracks conversions from your hosted store, while Siren tracks WooCommerce or EDD orders and other events on WordPress.

I just need a basic affiliate program. Isn't Refersion simpler?

For a Shopify store, often yes. Refersion is dev-free to install and its recruitment marketplace and managed payouts remove real operational work. But that simplicity comes with a percentage of your affiliate sales on top of the monthly fee, and your data lives in Refersion's cloud. On WordPress, Siren runs a basic affiliate program on its free Lite plan with no percentage cut, and gives you room to grow into royalties, revenue share, and bonuses later without changing tools.

Refersion has a marketplace and managed payouts. Why still consider Siren?

Those are genuine Refersion strengths, and if recruiting affiliates from a network and having payouts and 1099 forms handled for you are priorities, Refersion earns its place. Siren is worth considering when you are on WordPress, want flat pricing that does not scale with revenue, want to own your data, or need incentive programs Refersion does not model, such as course royalties, vendor revenue share, performance bonus pools, or several program types running at once.

Does Refersion's percentage fee really matter?

It can matter a lot as you grow. Refersion charges 3% of affiliate sales on Launch and 2% on Growth in addition to the monthly subscription, so the more successful your program becomes, the larger that cut gets. A program driving significant affiliate revenue can pay far more in percentage fees than the base subscription. Siren charges a flat annual price and never takes a percentage of affiliate revenue, so your cost is predictable regardless of program size.

Can Siren run more than one program at the same time?

Yes, and this is a core difference. Siren runs multiple program types side by side on one site, an affiliate program, a creator royalty, and a vendor revenue share for example, and a single conversion can reward several people. Refersion supports multiple offers and campaigns, and multi-store management on its Growth tier, but paying several partners or roles from one conversion is not part of its model.

What are the main gaps between Siren and Refersion?

Refersion is a hosted, ecommerce-first platform, and there are real reasons to choose it. It is purpose-built for Shopify and Shopify Plus (plus BigCommerce and Adobe Commerce), with native, one-click, generally available connectors that are more established and proven today than Siren's newer webhook-and-REST-API approach to those platforms through its Cloud and Full-Service editions. Its affiliate and influencer recruitment marketplace, one-click managed multi-currency payouts, and 1099 tax-form handling remove operational work (Siren pays collaborators automatically through Stripe on its Plus plan, but does not file 1099 tax forms for you). Its first-party cookieless tracking is mature and hardened for large ecommerce catalogs, and it offers influencer, ambassador, and MLM program models and dev-free hosted setup out of the box. Where Siren pulls ahead is on WordPress: self-hosted data ownership, flat annual pricing with no percentage cut of affiliate revenue, native WooCommerce, EDD, LifterLMS, and form tracking, and a wider range of incentive programs (course royalties, revenue share, bonus pools, and multiple program types at once).

Where each tool fits

These two overlap on affiliate tracking but diverge on platform, data ownership, and pricing model. Pick based on where your store runs and what you need beyond affiliates.

Choose Siren when…

  • Your store lives inside WordPress, on WooCommerce, Easy Digital Downloads, LifterLMS, or Gravity Forms, where the Siren plugin tracks orders, subscriptions, courses, and forms natively; non-WordPress stores can run the hosted Cloud or managed Full-Service editions instead.
  • You want flat annual pricing that never takes a percentage of your affiliate sales.
  • You want to own every collaborator, conversion, and payout on your own server.
  • You need incentive programs beyond affiliate and influencer tracking: course royalties, marketplace revenue share, performance bonuses, or several program types at once.
  • You would rather have Beacon, Siren's free AI assistant, turn your existing Refersion offers into a ready-to-install program recipe.

Choose Refersion when…

  • You sell on Shopify or Shopify Plus (or BigCommerce or Adobe Commerce) and want a native, one-click, generally available integration today. Refersion is purpose-built for these platforms, while Siren reaches them through its Cloud and Full-Service editions via webhooks and the REST API, which is newer and, for self-serve Cloud, still in founding access.
  • You want a built-in marketplace to discover and recruit new affiliates and influencers.
  • You want the vendor to run one-click managed payouts and handle 1099 tax forms for you.
  • You want a fully hosted tool with nothing to install or maintain, and dev-free setup.
  • You are comfortable paying a percentage of affiliate revenue in exchange for that hosted, ecommerce-first experience.

Programs Refersion Doesn't Run

Refersion does ecommerce affiliate, influencer, and MLM tracking well. Siren adds incentive program types Refersion does not model, for businesses that need more than affiliate tracking.

Course and Creator Royalties

Pay instructors or creators a share when their own courses or products sell, tracked through LMS events. Refersion has SKU royalties but no LMS or course-completion model.

Marketplace Vendor Revenue Share

Pay each marketplace vendor their cut of a sale automatically, based on which products they own rather than who referred the click. Refersion tracks referral links and SKU royalties, but has no vendor revenue-share model.

Performance Bonus and Top-Performer Pools

Schedule bonuses and reward pools based on aggregate performance over time. Refersion has no scheduled-bonus or top-performer-pool concept.

Multiple Rewards From One Conversion

Reward several partners or roles from a single sale, and run several program types side by side. Refersion pays a single attributed affiliate per conversion.

Self-Hosted Data and Flat Pricing

Keep collaborators, conversions, and payouts on your own WordPress site, with pricing that never skims a percentage of affiliate revenue.

What Refersion charges more for

Refersion's cost is a monthly subscription plus a percentage of affiliate sales, and its richest features sit behind the $199/mo Growth tier. Here is how that stacks up against a flat-priced Siren plan.

Percentage fee on affiliate sales Siren: Never. Flat annual pricing Refersion: 3% on Launch, 2% on Growth, custom terms on the Scale tier, on top of the monthly fee
REST API access Siren: Included in the free Lite plan Refersion: Growth ($199/mo) and above
Product and SKU-level commissions Siren: Included Refersion: Growth ($199/mo) advanced commissions
30+ marketing app integrations Siren: Core integrations included Refersion: Growth ($199/mo) and above
Multi-store management Siren: Multiple programs on one site, included Refersion: Growth ($199/mo) and above
Course / LMS royalty programs Siren: Included, tied to LMS events (e.g. LifterLMS) Refersion: Not available at any tier
Self-hosted data ownership Siren: Always. Data stays on your server Refersion: Not available. Cloud-hosted only

The percentage-of-sales math

The subscription is only part of the bill. Because Refersion also takes a percentage of every affiliate-driven sale (3% on Launch, 2% on Growth), your cost climbs as your program grows, exactly when it is working best. Siren's annual price stays flat no matter how much affiliate revenue you drive.
