Merchant of Record platform purpose-built for SaaS and apps

The verdict: can you vibe code Paddle?
Building a personal Merchant of Record clone is a non-starter because the barrier is not software code—it is legal liability across 300+ global tax jurisdictions. Keep paying the 5% + 50¢ MoR fee.
You can spin up a Stripe API wrapper with a database in a weekend, but that makes you a Payment Service Provider, not a Merchant of Record. To actually clone Paddle, you would need to legally incorporate local entities worldwide, acquire tax registration bonds in every US state and EU country, and expose your personal assets to foreign tax audits. An AI coding agent can build a slick Next.js dashboard and checkout drawer, but it cannot write code that legally absolves you of global VAT remittance liability.
Estimated effort: impossible (legal reality)
What you can't replicate
- Legal Merchant of Record reseller status and indemnification
- Global tax registration bonds and direct filing relationships with foreign tax authorities
- Absorbing fraudulent chargeback liabilities out of your own balance sheet

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js application with Tailwind CSS, configure Neon Postgres with Drizzle ORM, and set up the relational schema for merchants, products, prices, subscriptions, and transactions.
Scramble up a new Next.js project using App Router and Tailwind CSS. Configure Drizzle ORM to connect to a Neon Postgres database. Define a robust schema with tables for tenants (merchants), products, subscription prices, customers, subscriptions, and webhook_events. Include proper foreign keys, timestamps, and indexes for lookup performance. Ensure TypeScript strict mode is enabled throughout.02Authentication & Merchant Dashboard
Implement authentication using better-auth and build a multi-tenant dashboard allowing merchants to create products, set recurring billing intervals, and view revenue analytics.
Integrate better-auth for merchant user authentication supporting email/password and secure session management. Build a merchant dashboard interface with Tailwind CSS containing views for creating products, defining flat or recurring subscription prices, viewing active subscriber counts, and managing webhook endpoints. Create server actions to handle CRUD operations on products and pricing models securely.03Embeddable Checkout Widget & Mock MoR Engine
Build an embeddable client-side JavaScript snippet and overlay checkout modal that simulates Paddle's hosted checkout experience, calculating mock sales tax based on buyer country headers.
Develop an embeddable client-side JavaScript SDK and overlay checkout modal component that mimics Paddle Checkout. The checkout UI should collect customer billing details, simulate local currency formatting, calculate a mock regional sales tax rate based on the buyer's IP or country selection, and process payment securely via Stripe Elements in test mode. Upon successful payment, record the transaction in the database and trigger an internal MoR reseller record.04Subscription Lifecycle & Dunning Simulator
Implement subscription state machines handling renewals, trial periods, upgrades/downgrades, and automated dunning retry logic for failed payments.
Build a subscription lifecycle management engine supporting active, trialing, past_due, and canceled states. Add backend cron jobs or scheduled API endpoints to handle recurring billing renewals, mid-cycle prorations for plan upgrades or downgrades, and an automated dunning simulator that flags failed charges and schedules retry notification emails via Resend.05Webhook Dispatcher & Developer API
Create a secure webhook dispatching pipeline that notifies merchant endpoints of billing events (subscription created, payment succeeded, payment failed) with HMAC signature verification.
Implement a robust webhook delivery system in Next.js that listens for internal billing events and dispatches HTTP POST payloads to registered merchant endpoints. Include automatic retry backoff logic for failed webhook deliveries, event log tracking in the database, and HMAC-SHA256 signature headers for payload verification so merchants can authenticate incoming notifications securely.

Vibe code Paddle: FAQ
- Can you vibe code Paddle yourself?
- Don't bother — 12/100 vibecodeable. Building a personal Merchant of Record clone is a non-starter because the barrier is not software code—it is legal liability across 300+ global tax jurisdictions. Keep paying the 5% + 50¢ MoR fee.
- How long does it take to vibe code Paddle?
- impossible (legal reality) — roughly 80-120 hours (Subset billing app, excluding legal MoR liabilities) of hands-on time with an AI coding agent.
- How do you build your own Paddle?
- Scoped to personal use: Next.js on the front, Next.js API Routes behind it, Neon for data. Follow the 5-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Paddle without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: impossible (legal reality). The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Paddle instead of paying?
- About ~$32 one-time to start and ~$0-20/mo to run, versus 5% + 50¢ per transaction (MoR) for Paddle. Break-even: Infinite (You cannot clone Merchant of Record legal protection as a side project).
