How Cost Per Sale (Affiliate) Works
Cost per sale is the most widely used affiliate commission model. When an affiliate drives a visitor to the advertiser's site and that visitor purchases, the affiliate earns a flat fee or percentage of the sale value. Attribution is typically managed by a 30-90 day cookie window, if the visitor returns and purchases within that window, the affiliate still receives credit. CPS rates vary enormously: physical goods range from 3-10% of sale value, digital products from 20-50%, and B2B software subscriptions from 20-30% of first-year ARR.
Why Cost Per Sale (Affiliate) Matters for B2B Marketing
CPS perfectly aligns advertiser and affiliate incentives, affiliates only earn when you earn, eliminating risk of paying for non-converting traffic. This makes CPS the preferred model for brands with limited affiliate budgets. The trade-off is that top affiliates may prefer guaranteed-payment models (CPL or CPC) if conversion rates are low or sales cycles are long.
Cost Per Sale (Affiliate): Best Practices & Strategic Application
Set CPS rates by working backward from LTV. If your average customer LTV is $2,400 and CAC target is $400, you can afford up to a $400 CPS commission while maintaining profitability. Benchmark against competitors using tools like SimilarWeb or by joining competitor programs and reviewing their affiliate terms.
Agency Perspective: Cost Per Sale (Affiliate) in Practice
One common mistake is setting CPS rates too low to attract quality affiliates. If your rate is 5% and the average order value is $50, affiliates earn $2.50 per sale, that's not motivating for serious content publishers. For low-AOV products, consider adding performance bonuses for affiliates who exceed monthly volume thresholds.
Frequently Asked Questions: Cost Per Sale (Affiliate)
Cost per sale (CPS) in affiliate marketing is a commission model where the advertiser pays the affiliate only when a referred visitor completes a purchase.
CPS specifically measures a completed purchase. CPA (cost per action) is broader and can include any desired action, form fills, free trial signups, or app installs, not just purchases.
Research competitor programs, calculate your maximum allowable CPA based on LTV, and aim for the top 25% of rates in your category. Affiliates compare rates across programs before committing time.
Standard practice is to claw back commissions on refunded or charged-back sales. This should be clearly stated in your affiliate agreement, with a hold period of 30-60 days before commission payment.
