What Is Commission Structure?
Commission structure is the commercial foundation of any affiliate marketing programme. It determines how much affiliates earn, for which actions, under what conditions and within what timeframe.
A well-designed commission structure attracts high-quality affiliate partners, aligns their incentives with the merchant's business goals, and remains profitable as the programme scales. A poorly designed structure either fails to attract serious affiliates or erodes margins by paying commissions on low-value or fraudulent actions.
The most common commission models are: cost per sale (CPS), where affiliates earn a percentage of the transaction value or a flat fee per completed purchase; cost per lead (CPL), where affiliates earn a fixed fee for each qualified lead, sign-up or free trial registration; cost per action (CPA), where commissions are paid for specific actions such as app installs, quote requests or form completions; and recurring commissions, where affiliates earn a percentage of subscription revenue for the lifetime of a referred customer.
Each model suits different business types and affiliate profiles.
For South African affiliate programmes, the competitive commission rate for a given category can be researched by reviewing what comparable programmes on the major local networks pay. Retail and fashion programmes typically pay 5% to 12% of sale value.
Financial services programmes (insurance, loans, medical aid) pay R150 to R600 per qualified lead. Travel and accommodation programmes pay 4% to 8% of booking value. Software and SaaS programmes frequently pay 20% to 40% of first-year subscription revenue.
Understanding where your programme sits relative to these benchmarks determines whether affiliates will prioritise promoting your brand or your competitors.
Commission Structure In Practice
The scenario below is an illustrative example, not a Juicy Designs client result. The figures indicate the scale of effect that commission structure changes typically produce, so treat them as indicative rather than measured.
Imagine a South African online insurance comparison platform launching an affiliate programme with a flat R50 per completed quote commission.
After three months, a programme like this might attract very few affiliates, and those it did attract could plausibly generate quotes converting to policy purchase at only around 12%, below the threshold for profitability.
Research into competitor programmes would typically find that rates in the region of R150 to R300 per qualified lead are standard for comparable financial services products.
The commission could then be revised to something like R180 per quote, with an additional R350 success bonus paid when a quote converts to a policy within 30 days. A tiered structure of this kind would bring the total effective commission per converted customer to around R530, competitive with the market.
Affiliate recruitment would be expected to increase, quote quality to improve, and a programme of this kind could plausibly become profitable within around six months of the rate revision.
Cookie duration is a critically important but often overlooked component of commission structure. The cookie window determines how long after an affiliate refers a visitor the affiliate is credited if that visitor converts.
Standard cookie durations range from 7 to 90 days, with 30 days being most common.
For high-consideration purchases with long decision cycles, such as financial products, furniture, or business software, a 30-day cookie may not be sufficient to capture all the conversions that affiliates genuinely influence.
Programmes with longer cookie windows are more attractive to affiliates operating in high-consideration categories because they are less likely to lose commission credit to direct returns or retargeting touchpoints.
Types of commission structure
A commission structure is the arrangement that determines how much and on what basis a partner, affiliate or salesperson is paid for the results they drive. Several models exist. A flat-rate or fixed commission pays a set amount per sale or action, simple and predictable. A percentage commission pays a share of the sale value, aligning the reward with order size. A tiered structure increases the rate as a partner drives more, rewarding and motivating higher performers. Recurring commission pays repeatedly for ongoing revenue, such as subscriptions, for as long as the customer stays. Some structures combine elements, or vary the rate by product or category. In affiliate marketing especially, the commission structure shapes who is attracted to promote you and how hard they work, since partners gravitate to programmes that pay well and fairly, making the structure a key lever in the appeal and success of a programme.
Setting a commission structure
Setting a commission structure means balancing what you can afford against what will attract and motivate the partners or salespeople you want. The rate must leave acceptable margin after the commission and other costs, so it is grounded in your economics, while being competitive enough that partners choose your programme over alternatives, since too low a rate attracts little effort. The basis should suit the model: a percentage suits varying order values, a flat rate suits consistent ones, recurring commission suits subscriptions, and tiers can motivate volume. Clarity and fairness matter, since partners need to understand and trust how they are paid, and reliable, timely payment sustains the relationship. In affiliate marketing, the structure also signals how you value partners, influencing the quality of those who join. The aim is a structure that is profitable for the business, attractive and motivating for partners, and clear and fair enough to build a lasting, productive relationship.
FAQ
What commission rate should I offer affiliates?
Commission rates vary widely by industry. Physical products typically pay 5% to 15% of sale value because margins are lower. Digital products (software, online courses, subscriptions) commonly pay 20% to 50% because there is no physical fulfilment cost.
Financial services and insurance programmes often pay flat fees per qualified lead (R100 to R500 per lead in South Africa) rather than revenue share. Setting your rate requires knowing your customer lifetime value, acquisition cost ceiling, and what competing programmes in your category pay.
What is a tiered commission structure?
A tiered commission structure pays higher rates to affiliates who generate more volume or higher-quality conversions. For example, an affiliate who refers fewer than 10 sales per month earns 8%, while one who refers 50 or more sales per month earns 15%.
Tiered structures incentivise top affiliates to prioritise your programme over competitors and reward performance without raising your overall commission cost, since the higher rates only apply to your most productive partners.
What commission rate should you offer affiliates?
One that leaves acceptable margin after commission and costs while being competitive enough to attract and motivate the affiliates you want, since too low a rate wins little effort. The right rate depends on your margins, the product, and what comparable programmes offer, balanced so it is profitable for you and appealing to partners.
