The 30-Day SaaS MVP Playbook: How We Scope, Build, and Launch Production Software

What is the 30-Day SaaS MVP Framework?

The 30-Day SaaS MVP Framework is a fixed-scope, four-week product development cycle designed to turn a validated product concept into a revenue-generating production web application. Instead of building endless configuration options and speculative microservices, the framework focuses exclusively on the single core user loop, automated end-to-end testing, Stripe/Airwallex subscription checkout, and a unified Figma design token system.

WEEK 1: Foundation & Data Model ──► [Schema, Auth & Figma Tokens]
WEEK 2: Core Vertical Slices     ──► [Primary User Loop & Dashboard]
WEEK 3: Billing & Integrations  ──► [Airwallex/Stripe & Webhooks]
WEEK 4: QA, Polish & Handover   ──► [Playwright Suite & Production DNS]

Most startup MVP projects fail not because the code is bad, but because the scope is unbounded. Founders spend four months debating onboarding edge cases, custom analytics engines, and complex role-based permissions before a single real customer signs up.

Here is the exact milestone breakdown and architectural rulebook our studio uses to ship production software in 30 business days.

Week-by-Week Execution Timeline

Week 1: Architecture, Data Schemas, and Design Tokens

The first five business days establish the foundational constraints of the system.

• Day 1–2: Database schema design in TypeScript using Kysely or Prisma. We define strict foreign key relationships, database constraints, and index strategy before writing any application UI.
• Day 3: Authentication and team tenant isolation using Better-Auth or Auth0 with multi-tenant session tokens.
• Day 4–5: Figma-to-Tailwind token generation. We convert typography scales, dark/light theme palettes, and spacing rules into CSS custom properties.

import type { Generated, Selectable, Insertable } from "kysely";

export interface TeamsTable {
  id: Generated<string>;
  slug: string;
  name: string;
  plan_tier: "starter" | "growth" | "scale";
  billing_status: "active" | "past_due" | "canceled";
  created_at: Generated<string>;
}

export type Team = Selectable<TeamsTable>;
export type NewTeam = Insertable<TeamsTable>;

Week 2: The Core Vertical Slice

Week two is dedicated entirely to the primary value proposition of the product. If you are building an AI video generator, week two delivers the rendering job queue and video player. If you are building a B2B invoicing portal, week two delivers the invoice editor and PDF renderer.

• Strict Vertical Slices: Every feature slice spans the database table, API route, and responsive UI component.
• Mock External Third Parties: Use local in-memory stubs for external APIs during development so frontend engineers are never blocked by upstream rate limits or sandbox outages.

import { TypstRenderer } from "@typst-ts/core";

export async function compileInvoiceDocument(invoiceData: Record<string, any>): Promise<Uint8Array> {
  const typstMarkup = `
    #set page(paper: "a4", margin: 1.5cm)
    #set text(font: "Geist", size: 10pt)

    = Invoice #${invoiceData.id}
    *Bill To:* ${invoiceData.customerName}
    *Amount Due:* $${(invoiceData.amountCents / 100).toFixed(2)}

    #line(length: 100%, stroke: 0.5pt + gray)
  `;

  return await TypstRenderer.renderToPdf(typstMarkup);
}

Week 3: Billing, Webhooks, and Error Recovery

Software is not an MVP until it can accept money. In week three, we wire up payment infrastructure and transactional email notifications.

• Payment Provider: Stripe or Airwallex embedded checkout sessions.
• Webhook Handlers with Idempotency: Store all incoming webhook events in an inbound_webhooks table before processing to protect against duplicate payment notifications.
• Transactional Emails: Brevo or Resend API integrations for account verification, password resets, and receipt delivery.

export async function handleCheckoutWebhook(event: { id: string; type: string; data: any }, db: any) {
  // 1. Guard against duplicate events
  const recorded = await db
    .insertInto("webhook_logs")
    .values({ event_id: event.id, event_type: event.type, processed: false })
    .onConflict((oc: any) => oc.column("event_id").doNothing())
    .executeTakeFirst();

  if (!recorded) {
    return { status: "already_processed" };
  }

  // 2. Provision tenant license
  if (event.type === "checkout.session.completed") {
    await db
      .updateTable("teams")
      .set({ billing_status: "active", plan_tier: event.data.planTier })
      .where("id", "=", event.data.teamId)
      .execute();
  }

  return { status: "success" };
}

Week 4: Playwright E2E Gating, Production DNS, and Handover

The final week is all about automated verification, performance profiling, and repository handover.

• End-to-End Test Suite: We write 10 to 15 Playwright specs covering the critical path: user registration, team creation, payment checkout, core workflow completion, and PDF/data export.
• Lighthouse Performance Gate: Run automated audits on CI to guarantee 95+ scores for Performance, Accessibility, Best Practices, and SEO.
• Repository Pass-off: Hand over full admin permissions on GitHub, Cloudflare, and payment portals with a complete architecture README.

Production Milestone Checklist

The Three MVP Anti-Patterns We Ban

1. Premature Microservices: Never split an early-stage application across six independent backend repositories. Build a clean, modular monolith in TypeScript. You can always decouple services later when scale demands it.
2. Infinite Customization: Resist building configurable UI dashboards with drag-and-drop cards. Give users one opinionated, high-taste view that solves their problem instantly.
3. Skipping Automated Browser Tests: “We’ll write tests later after launch” is how startups die from regression bugs. Write concise Playwright specs for your three core user flows from day one.
