What you get with Refgrow + SaaS
Everything you need to run a professional affiliate program on top of SaaS.

Unlike other tools, Refgrow lives inside your SaaS app. Your customers become affiliates without leaving your product.

Track recurring commissions, handle subscription upgrades/downgrades, and calculate lifetime value automatically.
Works with All Major Billing
Native integration with Stripe, Paddle, Polar, Lemon Squeezy, and Dodo Payments. Connect in one click.
Zero Transaction Fees
Flat pricing from $29/mo. No percentage of your revenue, no hidden costs, no surprises.
Built-in Partner Network
List your eligible program, get discovered by partners in your niche, and invite relevant partners from your dashboard.
Fully Customizable
Match your brand colors, text, layout. 9 languages supported. White-label available.
Set up in 3 simple steps
Follow the provider connection, widget, and tracking steps for your program.
Sign up and connect your billing
Create a free account, connect Stripe, Paddle, or any supported provider. Webhooks are configured automatically.
Embed the affiliate widget
Add the public widget container and page.js to your SaaS app. Load latest.js separately on pages where referral attribution is needed.
<div id="refgrow" data-project-id="YOUR_PROJECT_ID"></div>
<script src="https://scripts.refgrowcdn.com/page.js" async defer></script>The widget uses the refgrow container and page.js. The separate latest.js script records referral attribution; it does not render the dashboard. Provider webhooks or API events are still required to confirm paid conversions.
Set commissions and launch
Choose your commission structure (e.g., 25% recurring), invite your first affiliates, and start growing.
Verify before you invite partners
After connecting SaaS, open a referral link in a fresh browser session and complete your test checkout. Check that the customer, sale, and commission appear in your workspace.
Attribution must reach checkout through the supported referral parameter, metadata, coupon, or email flow for your integration. Adding a tracking script alone does not connect every custom checkout.

How tracking works
Refgrow uses server-side webhook tracking for maximum reliability:
Referral link click
Cookie-based tracking captures the affiliate source.
Visitor signs up
Referral attribution is stored with the new user account.
Customer subscribes
Your billing provider sends a webhook to Refgrow.
Commission calculated
Based on your rules: recurring, one-time, tiered, or per-product.
Affiliate gets paid
Automatic payouts via PayPal or Wise when threshold is reached.
