Most affiliate programs do not fail because of the tracking platform or the creatives. They fail at the commission sheet. Pay too little and no serious publisher touches the offer; pay for the wrong event and you buy traffic that never turns into revenue. This guide explains the five payout models used across affiliate networks and direct partnerships, who they attract, where the risk sits, and a simple framework for choosing one. It is written for brands launching or repairing a program, and it draws on how we structure deals in e-commerce, lead generation and nutra verticals.
The five models at a glance
| Model | You pay when | Best for | Advertiser risk | Publisher appeal |
|---|---|---|---|---|
| CPS (cost per sale) | A tracked purchase is confirmed | E-commerce, subscriptions, SaaS self-serve | Lowest | Content, coupon, cashback, comparison sites |
| CPA (cost per action) | A defined action completes: trial, install, first deposit, sign-up | Apps, fintech, iGaming, nutra, trials | Low to medium | Media buyers, email, native and push traffic |
| CPL (cost per lead) | A qualified form or call is delivered | Insurance, education, home services, B2B, solar | Medium | Lead-gen specialists, PPC arbitrage, call centres |
| RevShare | A percentage of revenue for the customer’s lifetime or a fixed window | Subscriptions, iGaming, SaaS, marketplaces | Shared | Long-term content partners, influencers with loyal audiences |
| Hybrid | A smaller upfront CPA plus a smaller RevShare | Any vertical with recurring revenue | Balanced | Top-tier partners who want cash flow and upside |
The pattern to notice: the further down the funnel the paid event sits, the less risk the advertiser carries and the fewer publishers will run the offer. CPS is the safest and the hardest to scale; CPL is the easiest to scale and the easiest to abuse. Every good program is a deliberate position on that line.
CPS: cost per sale
Under a CPS deal the publisher earns a percentage of the order value, or a fixed amount per order, only when a purchase is confirmed. It is the default for e-commerce and for anything sold on a checkout page. Typical rates run from 3–8% for physical goods with thin margins, 10–20% for digital products and supplements, and 20–40% for software, courses and high-margin direct-to-consumer brands. Networks such as Impact, Awin, CJ, Rakuten and ShareASale are built around it, and the publisher mix is dominated by coupon, cashback, review and comparison sites.
The strengths are obvious: you only pay for revenue, the return on ad spend is easy to prove to finance, and the model is compatible with almost every tracking stack. The weaknesses are subtler. Coupon and cashback publishers sit at the end of the journey and often claim the commission on sales your own Google Ads or email already created, so an untended CPS program can show a great ROAS while adding very little incremental revenue. Returns, cancellations and payment failures also need a validation window, usually 30 to 60 days, before commissions lock, which slows publisher cash flow and pushes performance media buyers towards CPA offers instead.
CPA: cost per action
CPA pays a fixed amount for a defined action that is not necessarily a purchase: a free trial, an app install with a first session, a first deposit, an account funded above a threshold, a verified sign-up. The action is chosen by the advertiser to be the earliest event that reliably predicts revenue. This is the dominant model in nutra, fintech, iGaming, dating, mobile apps and any “try before you pay” business, and it is the model most media buyers want because the payout is fixed, fast and independent of the advertiser’s downstream conversion rate.
Pricing a CPA is a spreadsheet exercise. Take the average revenue you earn from a customer who completes the action, multiply by your gross margin, subtract the profit you need to keep, and the remainder is the ceiling. A nutra brand with a $45 first order, 40% reorder rate and 60% margin can afford a CPA well above what a single-order view suggests; a SaaS company whose free trials convert at 4% cannot pay much per trial at all, and should probably pay per paid conversion instead. The main risk in CPA is quality: a fixed payout per action rewards volume, so without event-level validation you will pay for trials that never convert, installs from incentivised traffic and deposits that are immediately withdrawn.
CPL: cost per lead
CPL pays for a lead: a completed form, a qualified phone call, a booked appointment. It runs the lead-generation economy in insurance, mortgages, solar, education, home services, legal and B2B software, and it is the model where the definition of the paid event matters most. “Lead” can mean anything from an email address to a call that lasted 90 seconds with a homeowner in a serviceable ZIP code, and the price should scale with the definition. A raw form fill in a competitive vertical may be worth $5; a live-transferred, pre-qualified call can be worth $150 or more.
Two controls separate profitable CPL programs from expensive ones. The first is qualification criteria written into the insertion order: required fields, geography, working hours, duplicate rules, call duration. The second is a scrub and return process: leads are reviewed within an agreed window and invalid ones are rejected before payment. Publishers accept this when the rules are clear and applied consistently; they leave when scrubs are arbitrary or late. Pair CPL with lead scoring in your CRM so that, over time, you can pay more for the sources that close and less for the ones that only fill the pipeline.
RevShare and hybrid deals
Revenue share pays the publisher a percentage of what the referred customer spends, either for a fixed window (first 12 months is common in SaaS) or for the customer’s lifetime (standard in iGaming and many subscription products). It aligns both sides perfectly: a publisher on RevShare only makes money if the customers they send stay and pay, so they self-select for quality and are far less likely to run incentivised or fraudulent traffic. The trade-off is time. RevShare income builds slowly, which is why media buyers who fund campaigns from cash flow rarely accept it and why content publishers, influencers and community operators with loyal audiences prefer it.
Hybrid deals exist to solve that tension: a reduced upfront CPA (enough to cover the publisher’s acquisition cost) plus a reduced RevShare (enough to reward retention). A subscription brand might offer $40 CPA or 40% RevShare, and a hybrid of $20 CPA plus 20% RevShare. In our experience the hybrid is the deal that keeps top-tier partners engaged for years, because it pays their bills this month and still gives them a reason to send customers who last.
How to price a commission
Start from unit economics, not from competitors
Work out contribution margin per customer over a realistic horizon (first order for CPS, 90 days for CPL, 12 months for subscriptions). Your maximum payout is the share of that margin you can give away and still hit your target profit per customer.
Then check the market
Look at what similar offers pay on the networks your target publishers use. If your ceiling is below market, fix the funnel or the average order value before launching; a below-market offer simply does not get promoted.
Tier the payout
Publish a base rate and reward volume or quality: higher commission above a monthly threshold, a bonus for first-time customers, a lower rate for coupon traffic and a higher one for content partners. Tiers let you pay top partners more without inflating the cost of everyone else.
Set validation windows and cookie duration deliberately
A 30-day cookie and 45-day validation is a sensible default for e-commerce. Shorter windows lower cost and publisher appeal; longer windows do the opposite. Whatever you choose, document it and apply it the same way to everyone.
Review quarterly
Compare incremental revenue by partner type against payout. The right commission for a coupon site and the right commission for a review site are rarely the same number, and both drift as your funnel changes.
Decision framework: which model fits your business
Choose CPS if you sell on a checkout page, can track orders reliably and want the lowest-risk program you can defend to a CFO. Add a lower coupon-site tier from day one. Choose CPA if your revenue starts with a non-purchase event (trial, install, deposit, sign-up) and you have enough data to know what that event is worth, and be ready to invest in validation. Choose CPL if you sell through a sales team or a call centre, and only after you have written a lead definition and a scrub process you can enforce. Choose RevShare if your revenue is recurring and you want partners who care about retention, accepting that scale will come slowly. Offer a hybrid to the partners who matter most, whatever your base model is.
Mature programs usually run more than one model at once: CPS for the network long tail, hybrid for the ten partners who drive most of the volume, and CPL or CPA for specialist traffic sources. The mistake is not choosing “the wrong model” but running a single flat rate for every partner type and wondering why the program plateaus.
Fraud and quality controls by model
Every payout model attracts the abuse that its paid event makes cheap. CPS draws cookie stuffing, trademark bidding and coupon-code leakage; the controls are click-to-conversion time analysis, brand-bidding monitoring and exclusive publisher codes. CPA draws incentivised traffic, bot installs and repeat sign-ups; the controls are post-action events (a second session, a first purchase, a retained day-7 user) and device and IP deduplication. CPL draws recycled, fabricated and duplicated leads; the controls are real-time validation of phone and email, duplicate windows across all sources and call-recording review. RevShare is the most self-policing model, but still needs chargeback and refund reconciliation so that reversed revenue reverses the commission.
Whatever model you run, write the rules into the program terms, share them with every partner at onboarding, and apply them evenly. Publishers can live with strict rules; they cannot plan around unpredictable ones. Done well, the commission model stops being a cost line and becomes the mechanism that decides which partners you attract, which customers they send and how long they keep sending them.
