Siren Affiliate Manager is an exceptionally well-designed and thoughtfully built WordPress plugin. If you're running an affiliate program with multiple affiliates, different transaction types, or custom engagement triggers that need to generate commissions, this tool gives you serious power and flexibility. What really sets it apart, though, is the developer. Alex has been incredibly helpful and willing to customize the plugin for my specific use case. More importantly, he was focused on creating real value for my business - not just billing hours. That kind of mindset is rare. The plugin is robust, flexible, and clearly built by someone who understands real-world affiliate program complexity. I can't recommend Siren highly enough.

What This Recipe Does

This recipe tracks a revenue share for a multi-vendor marketplace. Each linked vendor earns 70% of their own product sales by default, while the marketplace keeps the remaining 30%. When an order includes products from more than one vendor, every eligible vendor receives an independent commission for their own line items.

The EveryBindingWins resolver is what allows those commissions to coexist. Rather than selecting one collaborator for the order, it records qualifying commissions for all linked vendors represented in that order.

Starting a Marketplace with One Recipe

Applying this recipe is the smallest viable shape of a working multi-vendor marketplace. It gives founders the commission layer they need first: vendors as collaborators, products linked to those vendors, and a revenue split that records earnings on every sale. Apply the recipe, add vendors, link each vendor’s catalog, and begin taking orders. That lets an operator validate the marketplace model against real commission records before investing in vendor self-service screens, a custom storefront, or more complex payment operations.

A marketplace has a storefront, a payment process, and a commission-accounting layer between them. Siren is the commission-accounting layer. WC Vendors, Dokan, or custom WordPress code can provide the storefront, vendor dashboards, product editing, and shop-by-vendor pages. Your own payment process handles customer and vendor funds; Siren records who earned what under the program. For the full setup context, see Using Siren for Marketplaces.

The independent-earning pattern carries across marketplace verticals. Online Course Platform Starter applies it to instructors and enrollments, while Travel Destination Marketplace applies it to hosts and listings. Handmade goods, B2B catalogs, and services marketplaces can use the same underlying shape: vendors earn on the products or listings they own, and the platform retains its share.

Who It’s For

Founders building a marketplace MVP who need a clear vendor revenue-share model before investing in custom marketplace operations
Multi-vendor marketplace operators whose vendors sell through a shared storefront
WooCommerce store owners who need to review and record vendor commissions before paying vendors externally

How It Works

Apply the recipe, add vendors as collaborators, and link each vendor to the products they sell. When a customer buys a linked product, Siren records the product-sale engagement and calculates the vendor’s commission from the product line-item total. Shipping, taxes, and fees are not part of the commissionable amount. When several vendors have qualifying products in the same order, EveryBindingWins records a separate commission for each of them.

Each qualifying sale creates an obligation for the vendor’s accrued commission. Those accrued amounts are visible in the collaborator dashboard and through the REST API. Hold fulfillment until your refund window has passed. If an order is refunded before its obligation is fulfilled, Siren rejects the conversion and that unfulfilled obligation.

After the refund window, group eligible obligations by collaborator and export a CSV for review. Process vendor payments outside Siren, then mark the externally processed payouts as paid. Using Siren for Marketplaces and the guide on paying collaborators cover the workflow in more detail.

Siren accounts for commissions rather than moving money; processor fees, chargebacks, partial vendor-level refunds, and negative-balance management are outside what it does.

How the Marketplace Vendor Commission Works in Siren

1

Apply the commission program

The recipe starts vendors at 70% of their own product sales and leaves 30% for the marketplace. You can set the vendor share from 1% to 99%.
2

Link vendors to their products

Add each vendor as a collaborator and link them to the products they sell. A qualifying product sale is attributed to that product's linked vendor.
3

Credit every eligible vendor on a shared order

The EveryBindingWins resolver records a separate commission for every vendor with qualifying products in the order. A three-vendor order creates three independent commissions.
4

Calculate the commissionable amount

Commissions use product line-item totals. Shipping, taxes, and fees are excluded from each vendor's commission base.
5

Hold payouts through the refund window

Wait until your refund window has passed before fulfilling vendor obligations. A refund rejects its conversion and any obligation that is still unfulfilled.
6

Review and record payouts

Review eligible vendor obligations in the collaborator dashboard or through the REST API, export a CSV, pay vendors externally, and record the completed payouts as paid.

Why Use Siren for a Marketplace Vendor Commission?

Traditional marketplace software tools	Siren
Built for one program type	Built for multiple incentive programs
Often limited to one reward model	Supports commissions, bounties, royalties, revenue share, and bonuses
Rewards usually tied to one action	Rewards can be tied to different measurable actions
Harder to manage overlapping programs	Program groups and rules control how programs interact
May require multiple tools as you grow	Supports different partner programs from one system

Siren supplies the commission layer, not the storefront or payment rail, so it can sit alongside WC Vendors, Dokan, or custom WordPress code. Use it when you need each vendor to receive an independent commission record for the products they own, including when several vendors appear in one order, while also running affiliate or referral programs on the same site.

Similar Programs, and When to Use Each

Recipes that share machinery with this one, the rule that actually separates them, and the situation where the other recipe is the better pick.

Program	How it differs	Use it instead when
Course Creator Royalty Program	The Course Creator Royalty Program credits course sales through the newest binding wins resolver and defaults instructors to a 50% share, while the Marketplace Vendor Commission uses every binding wins and defaults to a vendor-majority 70/30 arrangement.	Choose it for a multi-instructor education site where each course creator should earn half of every enrollment.
Product Royalty Program	The Product Royalty Program defaults creators to 40% of their line items while the store keeps the rest, and uses newest binding wins where the Marketplace Vendor Commission uses every binding wins.	Choose it when you operate the store yourself and pay artists or designers a minority royalty on the work they contribute.

Frequently Asked Questions

What is a marketplace vendor commission?

A marketplace vendor commission is the share a vendor earns when their product sells through a marketplace. The vendor usually receives the larger share because they supply the product and handle fulfillment, while the marketplace keeps the rest for operating the storefront. This recipe starts with a 70% vendor share and a 30% marketplace share.

How does a marketplace vendor commission work?

Each product is linked to the vendor who owns it. When that product sells, Siren credits the linked vendor 70% of the product line-item total by default. On a shared order, each eligible vendor earns independently on their own products.

What happens when a customer buys products from multiple vendors in one order?

Every vendor whose qualifying products appear in the order earns their commission independently. The EveryBindingWins resolver does not select one vendor for the whole order.

How does Siren know which products belong to which vendor?

Add each vendor as a collaborator and link them to the products they sell. When a linked product is purchased, Siren attributes the product-sale engagement to that vendor.

Does the 70% include shipping, taxes, or fees?

No. Commissions are calculated from product line-item totals. Shipping, taxes, and fees are excluded.

Can I use a different commission rate?

Yes. The recipe's vendor commission rate can be set from 1% to 99%. This recipe applies one rate across the program; different vendor rates require separate programs or individual collaborator settings.

What happens when an order is refunded?

Siren rejects the refunded order's conversion and any related obligation that has not yet been fulfilled. Hold fulfillment until your refund window has passed. See [How Refunds Work](/documentation/general/how-refunds-work) for the refund lifecycle.

How do I pay vendors?

Accrued commission is visible in the collaborator dashboard and through the REST API. After the refund window, group eligible obligations by collaborator, export a CSV for review, pay vendors through your own process, and mark those externally processed payouts as paid in Siren. The [guide on paying collaborators](/documentation/getting-started/how-to-pay-collaborators) covers the workflow.

Does this recipe provide a vendor storefront or payment rail?

No. This recipe tracks commissions for vendor-owned products. You still need your own storefront, vendor operations, and payment process. WC Vendors, Dokan, or custom WordPress code can provide the operator's storefront layer. The [marketplaces documentation](/documentation/getting-started/marketplaces) explains where this workflow fits.
