Stripe powers the money, the platform takes a cut, everyone's happy.</p> <p>A three-sided marketplace is a different beast. We needed sellers to list products, creators to promote them, and buyers to purchase — with money, attribution, and incentives flowing correctly between all three on every single transaction.</p> <p>This is how we built Peddlum, the architecture decisions we made, and the things that almost broke us.</p> <p>The Core Problem<br> In a two-sided marketplace, a sale is simple: buyer pays seller, platform skims a fee, done.</p> <p>In our model, a single sale has to:</p> <p>Charge the buyer via Stripe<br> Split revenue between platform, seller, and creator<br> Attribute the sale to the right creator's tracking link<br> Apply the creator's tier multiplier<br> Update three different wallets atomically<br> Trigger fulfillment (file delivery OR SaaS webhook)<br> Fire notifications to all three parties<br> Get any step wrong and someone is underpaid. The hard part isn't the code — it's making sure the invariants hold under failure.</p> webdev
