SaaS Affiliate Commission Structures: A Complete Guide

The Four Main SaaS Affiliate Commission Models

Getting your commission structure right is one of the highest-leverage decisions in building an affiliate program. Set it too low and no one promotes you. Set it too high and you erode margin. Here are the four main models used by SaaS companies.

1. Flat Fee Per Conversion

Pay a fixed dollar amount for each paying customer an affiliate sends.

Pros: Simple to explain, easy to budget, no ongoing liability.

Cons: Less motivating for affiliates promoting higher-priced plans. Affiliates don't benefit if you upsell the customer later.

When to use it: Freemium or low-ticket SaaS ($20–$100/mo plans). A flat $25–$75 per conversion is competitive and predictable.

Example: "Earn $50 for every paying customer you refer."

2. Recurring Percentage

Pay affiliates a percentage of each subscription payment, month after month, for as long as the customer stays active.

Pros: Very attractive to serious affiliates — the commission compounds over time. Creates strong incentive to promote you over competitors.

Cons: Long-term financial liability. If your churn is high, the commission may outlast the value of the customer.

When to use it: When you have strong retention (net revenue retention > 100%) and solid LTV. 20–30% is the industry standard.

Example: "Earn 25% of every invoice from customers you refer, for as long as they stay subscribed."

3. One-Time Percentage of First Payment

Pay a percentage of the customer's first month (or year) of revenue. A middle ground between flat fee and recurring.

Pros: Higher than a flat fee (especially for annual plans), no long-term liability, still scales with plan value.

Cons: Less compelling than recurring for high-quality affiliates who have a loyal audience.

Example: "Earn 30% of the customer's first payment."

4. Tiered Commission

Increase the commission rate as affiliates hit volume milestones.

Pros: Rewards top performers without overpaying average ones. Creates strong motivation to scale.

Cons: More complex to explain and track. Requires solid affiliate dashboard tooling.

Example: "Earn 20% recurring for your first 10 referrals, 25% for 11–50, 30% for 50+."

What Rate Should You Pay?

The math starts with your LTV and CAC. A common heuristic: your affiliate commission should cost no more than your paid acquisition cost for an equivalent customer. If your average CAC from Google Ads is $200, paying $80 per affiliate referral leaves you ahead.

For recurring commissions, calculate the total commission liability over 12 months. If a customer pays $50/mo and you're paying 25%, that's $12.50/mo or $150 over the first year. Compare that to the $50/mo revenue and your gross margin — you need at least 70–80% gross margin for recurring commissions to work at these rates.

Cookie Duration and Attribution Windows

Cookie duration is how long after clicking an affiliate link a conversion will still be attributed to that affiliate. The industry standard for SaaS is 30–90 days. Trackli uses server-side ref codes that persist indefinitely until the user signs up — no cookie expiration to worry about.

Communicating Your Structure Clearly

Whatever you choose, write it plainly. Affiliates are often burned by vague terms and unexpected changes. Specify: the rate, what triggers the commission (trial start? first payment? trial-to-paid?), the payout minimum, and the payment schedule.

The clearer your terms, the more confident affiliates will be in promoting you consistently.
