Referral Program Built for Product-Led SaaS
Your users already love your product. Give them a referral link inside the dashboard, pay them automatically when their referrals upgrade. Zero friction, zero external portals.

What you get with Refgrow + PLG SaaS
Everything you need to run a professional affiliate program on top of PLG SaaS.
Embedded inside your product
The Refgrow widget is a one-line script tag that renders a full referral dashboard inside your app — settings page, account page, or anywhere else. PLG users hit zero friction.
Self-serve onboarding
Users discover the referral program organically, claim their link, and start sharing — no email campaign required. The widget surfaces stats inline as referrals come in.
Recurring subscription tracking
Native Stripe/Paddle/Polar/LemonSqueezy/Dodo integration. Track upgrades, renewals, and churn — pay recurring commissions or one-time bonuses on the qualifying event.
Per-user reward customization
Reward your top referrers with higher rates. Per-affiliate overrides let you negotiate without breaking your default rules.
Built-in Partner Network
List your eligible program for discovery, browse relevant partner profiles, and invite partners whose audience fits your product.
API for fully custom UX
If you want a custom in-product UX instead of the widget, our REST API gives you everything: referral link generation, conversion tracking, payout status.
Set up in 3 simple steps
Follow the provider connection, widget, and tracking steps for your program.
Connect your billing provider
Sign up, connect Stripe (or Paddle/Polar/etc.). Webhook is auto-configured. Refgrow starts capturing subscription events immediately.
Embed the widget in-app
Add the public widget container and page.js to your /account or /settings page. Load latest.js separately 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.
Pick a reward and ship
Common PLG patterns: 25% recurring on Annual, $20 flat per paid signup, or two-sided rewards (give a free month to both referrer and referee). Set it once, watch the loop run.
Verify before you invite partners
After connecting PLG 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 — fully accurate even when browsers strip third-party cookies:
User shares their referral link
Link surfaces from inside your product. They share with friends, on Twitter, in their company Slack.
Visitor signs up
Free signup is recorded. Refgrow stores attribution against the new user's email.
User upgrades to paid
Stripe/Paddle/Polar webhook fires when the subscription is paid. Refgrow matches the customer to the original referrer.
Commission calculated
Recurring percentage, one-time bonus, two-sided reward — whatever fits your PLG motion. Honored across renewals if you choose.
Referrer gets paid
PayPal or Wise auto-payout when their balance hits the threshold. Or apply credit to their next invoice via the API.
