Payment System Introduction

Introduction to Zooly payment and revenue distribution system

Introduction

Zooly is an intellectual property marketplace where content creators (buyers) pay celebrities/talent (sellers) for the right to use their likeness in AI-generated content. The payment system handles the full lifecycle: collecting payments from buyers, distributing revenue among multiple stakeholders, accumulating shares until payout thresholds are met, and transferring funds to talent via Stripe Connect.

Currency Convention

All monetary amounts are in integer cents, not dollars. Every variable, parameter, column, and API field that represents money must use the Cent suffix to make the unit unambiguous (e.g. amountCent, platformFeeCent, totalBrandPriceCent). Never store or pass currency as floating-point dollars in the payment system.

What the Payment System Does

Core Flows

Payment Collection — Charging buyers via Stripe for licenses (Voice, Image, Likeness), merch, and marketplace offers (payFor: "OFFER", escrow until delivery is accepted)
Revenue Distribution — Splitting each payment among 3 or more stakeholders: talent, platform (Zooly), Stripe fees, agents, ambassadors, host partners
Payout Accumulation — Holding earned shares in "open" tracking records until they exceed a per-user minimum threshold (default $100)
Payout Processing — Transferring accumulated funds to talent via Stripe Connect transfers
Advance Payouts — Pre-paying talent before they've earned the amount, then deducting from future earnings
Refunds — Reversing payments with negative tracking records and advance offsets
PPU (Payment Proof Url) — Generating unique PPU codes per completed transaction
Dual-Path Payment Completion — Client endpoint completes payments by verifying with Stripe API; webhook serves as a fallback

Product-Agnostic Design

The payment system is designed to be Product Agnostic. This means that the payment system doesn't know about specific products. Instead, the product details are stored in domain-specific tables.

The payment system is linked to the product via the payFor enum and the payForId foreign key.

The product details are stored in domain-specific tables.

Client Side - MISSING

Currently, only a server-side payment flow has been implemented. A client-side payment flow is planned to support the Product-Agnostic Design using a dedicated Stripe context provider.

Invariant

A payment consists of two linked records: a product record (product-specific) and a stripePayment record (generic Stripe payment details and status).

Creation Flow:

First, create a product record
Then, create a stripePayment record for this product
When payment completes, update the stripePayment record status to SUCCEEDED

Bidirectional Relationship:

stripePayment references the product via payForId/payFor fields
product references the stripePayment via stripePaymentId field

Amount Handling:

Payment amounts are never passed from the client to be saved in the database
The product record is the source of truth for payment amounts
Amounts are fetched from the database using getProductByPayForId() when needed

Querying Payments:

To retrieve complete payment details, always join both product and stripePayment records

Revenue Distribution Logic

Standard Payment (AI Creation — Voice, Image, Likeness)

Total Payment Amount (e.g., $100.00 = 10000 cents)
    |
    |-- Stripe Fee = $0.30 + 2.9% = $3.20 (320 cents)
    |-- Zooly Platform Fee = fixed AI creation cost (e.g., $5.00)
    |-- Talent Share = $100.00 - $3.20 - $5.00 = $91.80
    |
    |-- If talent has Agent: Agent gets X% of Talent share
    |   e.g., 15% of $91.80 = $13.77 → Talent gets $78.03
    |
    |-- If has Host Partner: Partner gets 10% of Platform share
    |   e.g., 10% of $5.00 = $0.50 → Platform gets $4.50
    |
    |-- If has Ambassadors:
    |   Each ambassador gets SAME 10% of Platform share (AMBASSADOR_SHARE = 0.1)
    |   Total deducted from platform = 10% * number_of_ambassadors
