Pay Per Sale (PPS)

Pay per sale (PPS) is the dominant commission model in affiliate marketing. An affiliate earns nothing for clicks or signups; the payout triggers only when the person they referred becomes a paying customer. The commission is usually a percentage of the sale, though it can also be a fixed amount per deal.

The model matters because it aligns incentives better than any alternative. The merchant spends money only after revenue arrives, which makes PPS the lowest-risk way to fund an acquisition channel. That risk profile is why nearly every B2B SaaS affiliate program is built on some form of it.

How it works in B2B SaaS

In SaaS, the sale is a subscription rather than a one-time purchase, which forces a design choice: pay a one-time commission on the first payment, or pay a recurring commission for as long as the referred customer stays subscribed. Recurring payouts are the SaaS norm because they mirror how the merchant itself earns revenue.

The mechanics run through tracking. The affiliate shares a tracked link, the click stores a cookie or click ID, and when that visitor starts a paid plan inside the attribution window the sale is credited to the affiliate. Because customers can refund or cancel quickly, most programs add a commission hold period before releasing the money, typically aligned with the refund policy.

Free trials add a wrinkle. Under PPS the trial signup itself pays nothing; the commission fires when the trial converts to a paid plan. Tracking therefore has to connect the original click to a payment event that may happen weeks later, which is why cookie duration and server-side conversion tracking matter so much in SaaS programs.

A worked example

Picture a project management SaaS priced at $100 per month that pays a 25% recurring commission for the first 12 months of each referred subscription.

An affiliate publishes a detailed comparison article and sends 1,000 visitors in a month. Around 40 start a free trial, and 10 of those convert to a paid plan. Each paying customer now generates $25 per month in commission for the affiliate.

That cohort is worth $250 per month, or up to $3,000 over 12 months if every customer stays. If two customers cancel after month three, their commissions simply stop, so the affiliate's real earnings land closer to $2,550.

From the merchant's side, a customer who stays a full year produced $1,200 in revenue and cost $300 in commission, a 25% channel cost that was only ever paid on real revenue. The clicks, the trials that never converted, and the churned months cost nothing.

Typical ranges and benchmarks

Published PPS terms cluster in a few familiar ranges:

• Recurring commissions of 20-30% of subscription revenue, paid for the first 12 months or for the customer's lifetime.
• One-time payouts of 50% to 100% of the first month's payment.
• A percentage of first-year contract value in sales-led programs.
• Attribution windows of 30 to 90 days.
• Commission hold periods of 30 to 60 days, so refunds settle before money moves.

Treat all of these as starting points. The right rate is a function of gross margin, churn, and customer lifetime value, not what a competitor's program page happens to say.

Pay per sale vs cost per acquisition (CPA)

Pay per sale and CPA get used interchangeably, and they should not be. In affiliate network jargon, CPA means cost per action, and the action can be a lead, an install, or a trial, none of which are sales. A CPA deal can pay out before any revenue exists; a PPS deal cannot.

CPA is also the name of a metric: what a merchant pays, on average, to acquire one customer through a channel. PPS is a commission model, not a metric. A PPS program produces a predictable acquisition cost because the payout per closed customer is defined up front, which is exactly why finance teams like it.

How it shows up in affiliate and partner programs

PPS is the default structure on most SaaS affiliate program pages, expressed as terms like 25% recurring for 12 months. The affiliate agreement around it should define:

• The commission rate.
• The attribution window.
• The hold period.
• Clawback rights for refunds.

Those terms are contractual, so have them reviewed properly; this is general guidance, not legal advice.

The same logic appears in partner programs under a different name: revenue share on referred deals. Referral partners, agencies, and resellers are often paid on a PPS basis even when nobody calls it affiliate marketing.

Common mistakes

The most damaging mistake is setting a rate without modeling churn and margin, then cutting it after affiliates have built content around it. Rate cuts are the fastest way to lose your best partners.

Skipping the hold period and clawback terms comes next. Refunds then create negative balances, disputes, and manual cleanup every payout cycle.

Finally, treating PPS as free growth. If referred trials never activate, affiliates earn nothing, conclude the program does not convert, and quietly stop promoting. Conversion on referred traffic is a shared problem, not the affiliate's alone.

Frequently asked questions

Is pay per sale the same as revenue share?

Revenue share is one way to price a PPS deal: the commission is a percentage of the revenue from the sale. PPS can also pay a fixed amount per sale. In other words, all revenue share is pay per sale, but not all pay per sale is revenue share.

When does the affiliate actually get paid?

Typically after a hold period of 30 to 60 days that lets refunds settle, then on the program's payout schedule, which is most often monthly with a minimum payout threshold. Recurring commissions repeat this cycle for every billing period the customer stays.

Should a SaaS program pay one-time or recurring commissions?

Recurring commissions align affiliates with retention and fit subscription economics, so they are the sensible default. One-time payouts are simpler and front-load the incentive, which some high-volume partners prefer. Many programs publish recurring terms and negotiate one-time bounties case by case.
