9 Affiliate Commission Models and How to Choose the Right One

What should an affiliate get paid for?

A click? A qualified lead? A completed sale? A recurring subscription? A specific milestone?

In this guide, we’ll compare the most common affiliate commission models, explain when each one makes sense, and help you decide whether pay-per-lead, pay-per-sale, or another reward structure is the right fit for your business.

What Is an Affiliate Commission Model?

An affiliate commission model defines which action earns a reward and how that reward is calculated.

For example, an affiliate might earn $50 for a qualified lead, 10% of a completed sale, or a recurring commission while a referred customer stays subscribed.

The model you choose tells affiliates which outcomes your business values and gives the program a clear structure for tracking credit and rewards.

9 Types of Affiliate Commission Models

Affiliate programs can reward different actions and calculate commissions in different ways. Common affiliate commission models include:

• Pay-per-click
• Pay-per-lead
• Pay-per-sale
• Flat-rate commissions
• Percentage commissions
• Recurring commissions
• Tiered commissions
• Revenue share
• Hybrid commission models

Pay-Per-Click

In a pay-per-click model, affiliates earn a commission when someone clicks their referral link.

This model rewards traffic, so it can work when reaching the right audience has value in itself.

The main trade-off is that clicks happen far from revenue. You need to pay close attention to traffic quality, duplicate activity, and potential click fraud.

Pay-Per-Lead

In a pay-per-lead model, affiliates earn a commission when a referred prospect completes a defined lead action like a demo request or a trial sign-up.

The key is defining what counts as a qualified lead before setting the commission. Without clear qualification, validation, and approval rules, businesses can end up paying for volume instead of real opportunities.

Pay-Per-Sale

In a pay-per-sale model, affiliates earn a commission only when a referred customer completes a purchase.

The reward may be a fixed amount or a percentage of the sale value.

This model is common when the customer can move directly from referral to purchase, such as in ecommerce, digital products, or other short buying journeys.

Because the reward is tied directly to revenue, the business takes on less acquisition risk. The trade-off is that affiliates may influence earlier stages of the buying process without receiving credit unless the final sale is attributed to them.

Flat-Rate Commissions

With a flat-rate commission program, affiliates earn a fixed amount for a defined action.

Flat-rate commissions work well when the business can assign a relatively consistent value to the rewarded action. The main benefit is predictability for both the business and the affiliate.

Percentage Commissions

With a percentage commission, affiliates earn a share of the value of a completed transaction.

For example, an affiliate might earn 10% of every referred sale.

This model is common when order values vary because the reward automatically scales with the revenue generated. Businesses still need to account for margins, discounts, refunds, and high-value transactions when setting the commission rate.

Recurring Commissions

Recurring commissions continue rewarding an affiliate while a referred customer remains active or continues paying.

For example, an affiliate might earn 20% of a customer’s subscription payments for 12 months.

Recurring commissions can align affiliate rewards with long-term customer value, but programs need clear rules around churn, upgrades, downgrades, and how long commissions continue.

Tiered Commissions

Tiered commissions change the reward as an affiliate reaches specific performance thresholds.

For example, an affiliate might earn 10% on their first 10 sales, 15% after 25 sales, and 20% once they pass a higher volume target.

Tiered commissions can encourage affiliates to keep promoting and reward stronger performers. The main challenge is keeping the structure simple enough for affiliates to understand and for the business to manage.

Revenue Share

In a revenue share model, affiliates or partners earn a defined portion of the revenue generated by the customers or accounts they refer.

It works well when the value of the relationship continues over time. However, businesses need clear rules around attribution, eligible revenue, refunds, account changes, and how long the revenue-sharing agreement lasts.

Hybrid Commission Models

Hybrid commission models combine two or more reward structures in the same program.

For example, a SaaS company might pay $50 for an approved lead, add a $200 bonus when that lead becomes a customer, and then pay 10% of subscription revenue for 12 months.

Hybrid models can better reflect complex customer journeys where affiliates or partners create value at multiple stages.

The trade-off is complexity. Each rewarded event, credit rule, and payout condition needs to be clearly defined so affiliates understand exactly how they earn.

Pay-Per-Lead vs Pay-Per-Sale: What’s the Difference?

The main difference between pay-per-lead and pay-per-sale is the event that triggers the affiliate reward.

With pay-per-lead, the affiliate earns when they generate a qualified prospect that meets the program’s requirements. With pay-per-sale, the affiliate only earns after the referred customer completes a purchase.

That difference affects how much of the customer journey the affiliate is expected to influence, how the business evaluates performance, and how risk is shared between the affiliate and the company.

	Pay-Per-Lead	Pay-Per-Sale
Rewarded event	Qualified lead	Completed sale
Revenue guaranteed	No	Yes
Sales team involvement	Usually higher	Usually lower
Qualification rules	Critical	Purchase confirms conversion
Affiliate conversion barrier	Lower	Higher

In many cases, the most important question is who controls the rest of the conversion process after the affiliate makes the referral.

If an affiliate generates a qualified opportunity but your sales team controls the next several weeks or months of the buying journey, rewarding only the final sale may not always create the right incentive.

On the other hand, when affiliates can send customers directly from a recommendation to checkout, pay-per-sale can tie commissions more closely to revenue.

How to Choose the Right Affiliate Commission Model

Start with the business outcome you want affiliates to create. Do you value traffic, qualified leads, completed sales, recurring revenue, or a combination of those events?

Then consider who controls the rest of the customer journey. If your sales team takes over after the referral, pay-per-lead may make more sense. If affiliates can drive customers directly to purchase, pay-per-sale may be a better fit. For more complex journeys, recurring, tiered, or hybrid commissions can reward value at multiple stages.

Which Affiliate Commission Model Fits Your Business?

The right affiliate commission model depends on where value is created in your customer journey and which actions affiliates can realistically influence.

Different business models may benefit from different reward structures.

Ecommerce Businesses

Pay-per-sale and percentage commissions are often a natural fit for ecommerce businesses because affiliates can send customers directly to a product page or checkout.

A program might pay 10% of each referred sale or use tiered commissions to reward higher-performing affiliates.

Ecommerce programs can also combine sale commissions with bonuses for specific products, order values, or performance milestones.

B2B SaaS Companies

Pay-per-lead or hybrid commission models can make more sense for B2B SaaS companies with longer, sales-led buying journeys.

An affiliate or partner might generate a qualified demo request, while the internal sales team manages discovery, follow-up, and closing.

A program could reward the approved lead, add a bonus when the account becomes a customer, and include recurring commissions tied to subscription revenue.

Service Businesses

Pay-per-lead is often a practical option for service businesses because the final sale may happen after a consultation, quote, or longer evaluation process.

Affiliates could earn for a qualified consultation request, booked appointment, or approved lead.

The key is defining clear qualification rules so the business rewards genuine opportunities rather than every form submission.

Marketplaces and Platforms

Revenue share can work well for marketplaces and platforms where referred users continue generating value through transactions or account activity.

Partners may earn a percentage of eligible revenue generated by the customers, sellers, or accounts they refer.

Hybrid structures can also reward important milestones, such as account activation, first transaction, or reaching a specific revenue threshold.

Final Takeaway

The right affiliate commission model starts with a simple question: what outcome do you want affiliates to create?

Pay-per-lead, pay-per-sale, recurring commissions, and tiered incentives all have a place. The best choice is the one that matches how your business creates value and who controls the conversion process after the referral.

Start with the event. Decide who should receive credit. Then build the reward around that outcome.
