    What costs go into each bucket for a platform startup?

    Same question, your business

    Quick answer

    For a platform, direct costs are what it takes to enable each transaction, overheads and R&D are the tech that runs the marketplace, sales & marketing (plus incentives) grows both sides, and G&A is the back office.

    The breakdown

    • Direct costs (): payment-processing fees, transaction support, fraud/insurance costs, and any per-transaction infrastructure.
    • Overheads: cloud and infrastructure to run the platform, monitoring, and operations.
    • Sales & marketing: acquiring both sides (buyers and sellers), plus the incentives, discounts and referral payouts you fund to build activity — often a huge early cost.
    • R&D: the engineering and product team building and maintaining the platform.
    • G&A: finance, legal, HR, admin, trust & safety, compliance.

    Our honest take

    For platforms, the sneaky cost is incentives — the money you pay out to keep both sides active. It behaves like a variable cost of each transaction and can quietly wipe out your take-rate margin. Track it inside your unit economics, not off to the side.
