PromoteKit

PromoteKit is an affiliate and partner program manager built for SaaS and digital-product businesses that bill through Stripe, and the PromoteKit Webflow integration is the fastest way to launch an affiliate program without writing tracking code. The native Webflow App auto-injects a tracking script, attributes referrals from affiliate links or coupon codes, and reads directly from Stripe so commissions calculate automatically across the entire customer lifecycle. For teams already selling on Webflow with Stripe, it removes the manual reconciliation that kills most referral programs.

What PromoteKit does on a Webflow site

• Auto-injects a tracking script through a native Webflow App, so no copy-pasting code into your site header or Embed components.
• Tracks the full Stripe lifecycle — trials, conversions, refunds, and cancellations — so commissions reflect what actually happened in billing, not just the first click.
• Supports two attribution methods: affiliate links and coupon codes, letting you run link-based partners and code-based promotions side by side.
• Calculates commissions automatically, including one-time, recurring, tiered, and product-based rules tied to specific Stripe products.
• Hosts a customizable affiliate portal on your own domain (Pro and above) with light and dark themes, where partners log in to track clicks, referrals, and payouts.
• Pays affiliates in bulk through PayPal Mass Payments and Wise Batch Payments, so you can settle an entire program in one action.

How PromoteKit tracks Stripe commissions automatically

PromoteKit treats Stripe as the source of truth. When a visitor clicks an affiliate link, the tracking script stores the referral against that partner; when the same visitor later checks out through Stripe, PromoteKit matches the conversion and records the commission. For subscription businesses it keeps tracking after the first payment — recurring commissions accrue on each billing cycle, and if a customer downgrades, refunds, or cancels, PromoteKit adjusts or claws back the commission to mirror Stripe. Trials are tracked from sign-up so partners get credit when a trial converts, and you can cap commissions to a set number of payments.

This is what makes an affiliate program Webflow Stripe setup genuinely hands-off: there is no CSV export, no monthly reconciliation, and no need to webhook commission logic yourself. Setup difficulty depends on how you bill. Stripe Payment Links require the least work — drop the PromoteKit script on the site and attribution flows automatically. Custom Stripe Checkout or subscription creation API calls require passing a metadata parameter during checkout creation, which is a few lines of code.

How to set up an affiliate program with PromoteKit on Webflow

1. Install the PromoteKit app from the Webflow App Marketplace, or sign up at promotekit.com and connect your Webflow workspace.
2. Authorize the requested permissions — read authorized users, read and write custom code, and read and write site data and publishing — so PromoteKit can inject its script.
3. Confirm the tracking script is live on your site; the app adds it automatically once authorized, with no manual header edits.
4. Connect Stripe (required). Stripe Payment Links need the least setup; Stripe Checkout and the subscription API are supported with a metadata parameter.
5. Optionally connect Memberstack or Outseta if you run a membership site — both offer a single-script integration for referral tracking on gated content.
6. Configure commission rules: percentage, one-time or recurring, product-based rates per Stripe product, currency conversion, and tier thresholds for high-performing partners.
7. Customize the affiliate portal (custom domain and branding on Pro and above), invite or approve affiliates, then enable payouts through PayPal Mass Payments or Wise Batch Payments.

PromoteKit pricing

PromoteKit charges a flat monthly subscription with no transaction fees on any plan, so your cost stays predictable as referral volume grows. The Free tier is generous enough to validate a program, Pro unlocks the advanced features most real programs need, and Enterprise covers custom implementation above $10k per month in affiliate revenue. Annual billing on Pro saves about 25%. Understanding PromoteKit pricing up front matters because the caps are on referrals and affiliate revenue, not on the number of affiliates you can recruit.

Best PromoteKit + Webflow use cases

SaaS referral programs

Run a partner program on top of Webflow marketing pages and Stripe subscriptions, with recurring commissions that accrue every billing cycle and adjust automatically on upgrades, downgrades, and cancellations.

Digital product launches

Give launch partners coupon codes that track purchases back to them, so creators promoting a course, ebook, or template bundle get credited without affiliate links that break on social platforms.

Membership referrals

Pair PromoteKit with Memberstack or Outseta to add a referral layer to a gated membership, attributing sign-ups and recurring dues to the referring member automatically.

Tiered commission programs

Reward top performers with higher rates using commission tiers — for example, lifting a partner from 20% to 30% once they cross a referral threshold — without manual rate changes.

Agency and client campaigns

Run multiple affiliate campaigns across client Webflow sites, using the Free or Pro tier per program and paying each client's affiliates through bulk PayPal or Wise payouts.

Limitations to know

• Automatic commission tracking requires Stripe as the payment processor; other checkout providers are not supported for hands-off tracking.
• The Free plan is capped at 3 referrals and 1 campaign, making it effectively a trial rather than a production tier.
• Pro at $29/month is limited to $10,000/month in affiliate revenue; programs above that require Enterprise with custom pricing.
• PromoteKit is not a CRM or email platform — you still need separate tools for affiliate communication, marketing, and partner relationship management.
