Overview

<p><b>Startup description</b></p><p>My platform is a production-ready, fully automated Micro-SaaS that enables users to send secure online faxes instantly without creating an account or signing up for monthly subscriptions. Built on a pay-as-you-go model, it provides a seamless, friction-free alternative to traditional, clunky fax software.</p><p>The product features a clean UI, automated email-to-fax routing, secure payment processing via Stripe, and a resilient serverless infrastructure. It is designed for complete hands-off operation, requiring less than 1 hour of maintenance per week.</p><p><b>Key Highlights</b></p><ul> <li><b>Annual Revenue:</b> $70 (TTM)</li> <li><b>Annual Profit:</b> $58 (TTM)</li> <li><b>Churn Rate:</b> N/A (Pay-as-you-go transactional model, no recurring lock-in)</li> <li><b>LTV:</b> ~$5 - $15 per active user session</li> <li><b>CAC:</b> $0 (100% organic direct traffic; no paid ads run to date)</li> <li><b>Business Margin:</b> ~83% net margin</li> <li><b>Other Metrics:</b> High payment conversion rate due to no mandatory registration wall.</li> </ul> <p><b>Team</b></p><ul> <li><b>Solo Founder &amp; Developer:</b> Responsible for full-stack engineering, UI/UX design, payment integration, third-party API management, and day-to-day customer support.</li> <li>Note: Post-sale, the system runs on complete autopilot and requires zero ongoing engineering headcount.</li> </ul> <p><b>Tech Stack</b></p><ul> <li><b>Frontend:</b> Next.js / React with Tailwind CSS (modern, fast, and SEO-friendly)</li> <li><b>Backend:</b> Node.js / Serverless functions for high scalability and minimal hosting overhead</li> <li><b>Database &amp; Auth:</b> PostgreSQL / Supabase</li> <li><b>Payment Gateway:</b> Stripe Integration (supports pay-per-fax dynamic pricing)</li> <li><b>Fax Infrastructure:</b> Twilio / Telnyx API integration for real-time fax status tracking and webhooks</li> </ul> <p><b>Marketing and Growth</b></p><ul> <li><b>Past Activities:</b> 100% organic growth via direct search and word-of-mouth.</li> <li><b>Results:</b> Proven end-to-end payment flow and successful delivery of real-world faxes with zero ad spend.</li> <li><b>Growth Potential:</b> We have operated with <b>zero paid advertising</b> so far. The fax market is heavily driven by intent-based keywords (e.g., "send fax online without account"). Implementing targeted Google Search Ads, programmatic SEO, or basic backlink building presents immediate revenue expansion opportunities.</li> </ul> <p><b>Revenue and Profit</b></p><ul> <li><b>ARR / TTM Revenue:</b> $70</li> <li><b>Net Profit:</b> $58</li> <li><b>Profit Margin:</b> ~83% (minimal serverless hosting + API costs only on successful usage)</li> <li><b>GMV:</b> $70</li> <li><b>Financial Model:</b> Pay-as-you-go per page / per document. Extremely lean cost structure where server costs scale directly with usage.</li> </ul> <p><b>Return on Investment&nbsp;</b></p><ul> <li><b>Payback Strategy:</b> Buyers can easily recoup their initial investment within 3–6 months by launching a targeted Google Ads / PPC campaign (bidding on high-intent fax terms) or setting up programmatic SEO pages for regional fax terms.</li> <li><b>Pricing Upside:</b> The current pay-per-page fee can be adjusted upward, or converted into a tiered credit/subscription model to boost Average Order Value (AOV) and customer LTV.</li> </ul> <p><b>Startup Assets</b></p><ul> <li><b>Complete Source Code &amp; Intellectual Property:</b> 100% ownership of the repository (Frontend, Backend, and Webhook scripts).</li> <li><b>Domain Name:</b> Full transfer of the primary brand domain.</li> <li><b>Database &amp; User Logs:</b> Anonymized transaction records and user contact database.</li> <li><b>Vendor &amp; API Accounts:</b> Assistance with transferring or reconnecting Stripe, Twilio/Telnyx, and hosting accounts.</li> <li><b>Customer Support Documentation:</b> Operational handover documentation and 14 days of post-sale support/onboarding.</li> </ul> <p><b>Risks and Mitigation</b></p><ul> <li><b>Risk 1: Third-party API Dependencies (Twilio/Telnyx).</b></li> <li>Mitigation: The backend architecture is modular, allowing easy switching or load-balancing between different telecommunication API providers if rates change.</li> <li><b>Risk 2: Lack of recurring subscription revenue.</b></li> <li>Mitigation: The pay-as-you-go model lowers conversion friction for one-off users. A buyer can easily introduce a subscription plan (e.g., $9.99/mo for unlimited faxes) alongside the pay-per-use option.</li> </ul> <p>Summary</p><ul> <li><b>Turn-Key Asset:</b> Rebuilding this complete codebase, secure fax API integration, and Stripe flow from scratch would cost over $8,000–$10,000 in developer resources and weeks of work.</li> <li><b>Zero Maintenance:</b> Operates virtually on autopilot with negligible server costs when idle.</li> <li><b>Huge Marketing Upside:</b> You are acquiring a production-ready, validated product that has <b>never been marketed with paid ads</b>. Perfect for an buyer with digital marketing or SEO skills looking for an immediate growth playbook.</li> </ul> <p>✅ $70 TTM revenue</p><p>✅ 30 customers</p><p>✅ Business model: One-time sales</p><p>✅Built with Node.js, Cloudflare, Supabase</p>

Number of Customers

Expenses

$12 for Domain registration, $2 for serverless hosting & API processing fees.

Business Model

Pay-as-you-go / One-time charge per fax. Users pay instantly for each fax sent without requiring an account or monthly subscription. Pricing can be dynamic based on document size/pages, yielding ~83% gross margins after API/serverless processing fees.

Target Audience

Individuals, freelancers, legal/medical professionals, and small business owners who need to send an occasional fax quickly without signing up for expensive monthly subscription plans or creating an account.

Asking Price Reasoning

The price reflects the value of a production-ready, fully functional codebase and infrastructure. Rebuilding the automated email-to-fax system, Stripe pay-as-you-go workflow, and UI from scratch would require thousands of dollars in engineering effort.

Reason for Selling

I am a solo developer focusing on building new projects. I don't have enough time or expertise to execute marketing and ad campaigns, so I want to hand this fully developed Micro-SaaS over to someone who can scale it through growth marketing and SEO.

Growth Opportunity

1. Launch targeted Google Search Ads (PPC) targeting high-intent keywords like "send fax online without account". 2. Implement Programmatic SEO to automatically generate landing pages for city/region-specific fax searches. 3. Add optional recurring subscritions.
