Key takeaways
- Marketplaces can run two affiliate programs: one to acquire supply (sellers/providers) and one to acquire demand (buyers).
- Base commissions on your take-rate revenue, not gross transaction value, or the math won't work.
- Supply-side referrals can be worth more than demand-side because a new seller brings ongoing inventory.
- First-transaction or qualifying-action triggers avoid paying for users who would have joined anyway.
- Track conversions server-side because marketplace journeys span sessions, devices, and both sides of the platform.
Marketplaces have a growth problem no single-sided business shares: they must acquire two populations at once, and each side makes the other more valuable. Affiliate marketing can fuel both sides, but only if the commission economics respect that you earn a slice of each transaction — not the whole thing.
Which side of the marketplace should affiliates grow?
Both sides can be grown with affiliates, and the more constrained side usually deserves the more generous program. In most early marketplaces, supply is the bottleneck — without sellers, drivers, or providers there's nothing for buyers to buy. A supply-side referral that brings a productive seller can be worth far more than a single buyer, because that seller generates transactions for months.
- Supply-side program — reward partners for recruiting active sellers/providers; high value because supply creates ongoing transactions.
- Demand-side program — reward partners for bringing buyers who transact; closer to classic ecommerce affiliate marketing.
- Run both — but weight commissions toward whichever side is your current constraint.
How do you set commissions on a take-rate business?
Base affiliate commissions on your take-rate revenue, not on gross transaction value. If you take 15% of each transaction, paying an affiliate a percentage of the full transaction value can easily exceed what you actually earn. Express commissions as a share of your net revenue, or as a flat amount you've confirmed is profitable per acquired user or transaction.
Run the take-rate math first
On a marketplace, the affiliate's commission and your revenue both come out of the same transaction. If you earn a 15% take rate and promise affiliates 10% of gross transaction value, you've handed away most of your margin. Always express commissions against your net (take-rate) revenue.
What event should trigger a commission?
Trigger commissions on a qualifying action — a first completed transaction or an active listing — not merely on signup. Marketplaces accumulate sign-ups who never transact, and paying on registration alone funds dead accounts. Tie the commission to the moment a new user creates real value: a buyer's first paid order, or a seller's first completed sale.
- Buyer side — pay on the referred buyer's first completed (and non-refunded) transaction.
- Seller side — pay when the referred seller completes their first sale, or lists qualifying active inventory.
- Consider a recurring or bonus component for sellers who stay active, since their ongoing supply is the real prize.
- Set a clear qualifying definition in your terms so partners know exactly what earns a commission.
How do you track conversions across a two-sided journey?
Track server-side, because marketplace journeys cross sessions, devices, and the boundary between browsing and transacting. A referred seller might click a link on mobile, sign up on desktop weeks later, and complete a first sale after onboarding. Cookie-only attribution will lose much of that. Persist the referral identifier against the user account and fire conversions from your backend when the qualifying action occurs.
On a marketplace, the affiliate who brings you a productive seller has given you a supply engine, not a single sale. Pay for the qualifying action that creates lasting value, against the revenue you actually earn.
How does Afflio fit a marketplace program?
Afflio is well suited to two-sided programs because attribution and commissions are decoupled from any single checkout. You can run separate campaigns for supply and demand, fire server-to-server conversion events from your backend keyed to whatever qualifying action you define, apply flat, percentage, tiered, or recurring rules against your take-rate revenue, and pay partners directly via RazorpayX (bank/UPI) and PayPal. Its built-in marketplace also lets partners discover programs to promote — useful when recruiting partners to grow your harder side.
Should a marketplace run affiliate programs for buyers or sellers?
Both can work, but weight the program toward your constrained side. In most early marketplaces, supply is the bottleneck, so a referral that brings a productive seller is often worth more than one that brings a single buyer because the seller generates ongoing transactions.
How should marketplace affiliate commissions be calculated?
Base them on your take-rate (net) revenue, not gross transaction value. If you earn a percentage of each transaction, paying affiliates a share of the full transaction value can exceed what you actually make. Express commissions against net revenue or a confirmed-profitable flat amount.
When should a marketplace pay an affiliate commission?
On a qualifying action that creates real value — a referred buyer's first completed transaction or a referred seller's first completed sale — rather than on signup alone, since marketplaces accumulate sign-ups who never transact.
