This is for marketplace platform fee design. --- ## Core Principle MARKETPLACE FEES MUST BE LOW ENOUGH THAT SELLERS STAY ON THE PLATFORM AND HIGH ENOUGH TO BUILD A SUSTAINABLE BUSINESS — THE FEE SHOULD NEVER EXCEED THE VALUE THE PLATFORM CREATES. --- ## Phase 1: Brief ### Required Inputs | Input | What to Ask | Default | |-------|------------|---------| | **Marketplace type** | "What does your marketplace connect?" | No default — must be provided | | **Average transaction value** | "What is the typical transaction amount?" | No default — must be provided | | **Transaction volume** | "How many transactions per month (current or projected)?" | 100/month projected | | **Competitors** | "Who are your top 3 competitors and what do they charge?" | No default — research needed | | **Current fees** | "What do you charge now, if anything?" | Nothing (pre-revenue) | | **Value provided** | "What does the platform do for sellers beyond connecting them to buyers?" | Payments, discovery, trust | **GATE: Confirm the brief before designing the fee model.** --- ## Phase 2: Fee Model Options ### Common Marketplace Fee Models | Model | How It Works | Best For | |-------|-------------|----------| | **Commission** | % of each transaction | High-volume, variable-price marketplaces | | **Listing fee** | Fixed fee per listing | Product marketplaces with many listings | | **Subscription** | Monthly fee for seller access | Professional service marketplaces | | **Freemium** | Free basic + paid premium features | Marketplaces building supply quickly | | **Lead fee** | Fee per qualified lead or inquiry | Service marketplaces with high-value transactions | | **Hybrid** | Combination of above | Mature marketplaces with diverse revenue needs | ### Commission Rate Guidelines | Transaction Value | Typical Commission | Rationale | |-------------------|-------------------|-----------| | Under $50 | 15-25% | Higher rate needed for unit economics | | $50-500 | 10-20% | Standard range for most marketplaces | | $500-5,000 | 5-15% | Lower rate to keep high-value sellers | | Over $5,000 | 3-10% | Volume-based, sellers are price-sensitive | ### Who Pays the Fee | Option | Pros | Cons | |--------|------|------| | Seller pays | Simple, common, hidden from buyer | Sellers build fee into price | | Buyer pays (service fee) | Seller gets full price, transparent | Buyer sticker shock | | Split | Fair perception | Complex to communicate | **GATE: Confirm the fee model and rate range before building the structure.** --- ## Phase 3: Build the Fee Structure ### Base Fee Design Document the core fee structure: - **Who is charged:** Buyer, seller, or both - **When charged:** At booking, at completion, or monthly - **Rate:** Fixed amount, percentage, or tiered - **Minimum fee:** Floor amount per transaction (if applicable) - **Payment processing:** Who absorbs the 2.9% + $0.30 processing cost ### Premium Seller Tiers Design 2-3 tiers for sellers: ``` ## Seller Tiers ### Basic (Free) - Standard listing placement - [X]% commission per transaction - Basic analytics - Standard support ### Professional ($29/month or reduced commission) - Priority listing placement - [X-3]% commission per transaction - Advanced analytics and conversion tracking - Featured in buyer emails - Priority support ### Enterprise (Custom) - Custom commission rates - Dedicated account manager - API access - Custom branding options - Volume discounts ``` ### Competitive Analysis Template | Competitor | Commission | Listing Fee | Subscription | Other Fees | |-----------|-----------|-------------|-------------|-----------| | [Competitor 1] | | | | | | [Competitor 2] | | | | | | [Competitor 3] | | | | | | **Your Platform** | | | | | **Positioning strategy:** Price below the market leader but above the cheapest option. Compete on value, not price. --- ## Phase 4: Polish ### 1. Fee Communication Write clear fee explanations for: **Seller-facing:** "You keep [X]% of every transaction. We charge a [Y]% platform fee that covers payment processing, buyer acquisition, dispute resolution, and platform maintenance. No hidden fees, no surprises." **Buyer-facing (if applicable):** "A small service fee of [X]% is added to your order. This covers secure payments, buyer protection, and customer support." **FAQ entries:** - When are fees charged? - How are fees calculated on discounted or refunded transactions? - Are there any additional fees beyond the commission? - How do I upgrade to a premium tier? ### 2. Fee Revenue Projections Provide a simple projection template: ``` Monthly Transactions: [X] Average Transaction Value: $[Y] Commission Rate: [Z]% Gross Revenue: X * Y * Z Minus: Payment processing (~2.9% + $0.30 per transaction) Minus: Refunds and disputes (~2-5% of gross) Net Platform Revenue: [Result] ``` ### 3. Quality Checklist ``` ## Fee Structure Checklist - [ ] Fee model selected with rationale - [ ] Commission rate benchmarked against 3+ competitors - [ ] Who pays (buyer, seller, or split) is decided and justified - [ ] Premium seller tiers defined with clear value at each level - [ ] Minimum transaction fee set (if applicable) - [ ] Payment processing costs accounted for - [ ] Fee communication copy written for both sellers and buyers - [ ] FAQ covers fee calculation, timing, refunds, and upgrades - [ ] Revenue projection model created - [ ] Fee is sustainable (covers costs + margin) at projected volume ``` --- ## Example **Marketplace:** Freelance design services **Average transaction:** $750 **Fee structure:** - 12% commission on seller (seller receives $660) - 5% service fee on buyer (buyer pays $787.50) - Total platform revenue per transaction: $127.50 - Payment processing absorbed by platform **Premium tier pitch:** "Go Pro for $49/month: Drop your commission from 12% to 8%. On your average $750 project, that saves you $30 per transaction. If you complete 2+ projects per month, Pro pays for itself." --- ## Anti-Patterns - **Hidden fees** — surprising sellers with fees they did not expect kills trust and generates chargebacks. Be transparent. - **Charging before value is delivered** — listing fees before any sales discourages supply. Commission-based models align incentives. - **Race to zero** — competing solely on lower fees attracts price-sensitive sellers who leave when a cheaper option appears. - **Overcomplicating tiers** — more than 3 tiers creates confusion. Keep it simple. - **Ignoring payment processing costs** — 2.9% + $0.30 per transaction adds up. Account for it in your revenue model. --- ## Recovery - **Sellers resist the fee:** Demonstrate the value — what does the platform provide that justifies the cost? If you cannot articulate it, the fee is too high. - **Buyers resist service fees:** Test absorbing the fee into the seller's commission. Hidden fees feel worse than slightly higher prices. - **Revenue is not covering costs:** Either increase volume (more transactions) or increase take rate (higher fee). Raising fees on existing sellers requires advance notice and justification. - **Competitor undercuts on price:** Compete on value, not price. Better sellers, more buyers, superior trust features justify a premium.
