[removed]

I built a full vertical SaaS platform specifically for plumbing companies and I'm considering selling the entire codebase, architecture, and IP rather than taking it through a full commercial launch myself.

To be transparent: this is a pre-revenue technology acquisition, not an established SaaS business. There are currently $0 MRR and no production customers.

I recently ran a buyer-side forensic valuation of the repository, deliberately treating it as a pre-revenue software asset rather than assigning value to hypothetical revenue.

The internal valuation model came back at:

• $23,000 USD — asking price
• $26,500 — hypothetical maximum buyer wire
• $28,500 — estimated technology FMV
• $78,500 — estimated agency replacement cost

These are valuation estimates, not an external M&A appraisal.

What's built

This is a functioning multi-tenant application rather than a landing page or prototype:

• Multi-tenant plumbing company architecture
• Dispatcher / operations dashboard
• Technician mobile PWA
• Customer portal and permanent accounts
• Customer booking
• Dispatch and technician workflows
• Job state management
• Labor/time tracking
• Parts & materials
• Customer signatures
• Before/after photos
• Estimates
• Invoicing
• Tax engine
• Stripe Connect
• Stripe webhook idempotency
• Private file storage/proxy
• RBAC and tenant isolation
• PostgreSQL + Prisma
• Redis/BullMQ background processing
• Notifications/outbox architecture

Testing

The current repository has 47 test suites / 269 automated tests passing.

I've also built a dedicated multi-tenant load/acceptance harness that creates synthetic companies, staff and customers and tests:

• Cross-tenant IDOR attempts
• Customer isolation
• Staff authorization boundaries
• Concurrent authentication/token redemption
• Duplicate Stripe webhook delivery
• Financial idempotency
• Database integrity
• Synthetic-data cleanup
• Load and soak scenarios

The latest test runs reported zero cross-tenant leaks, zero unauthorized mutations, zero duplicate payment effects and zero test-data residue across the tested scenarios.

Obviously, passing automated tests doesn't mean "zero possible bugs forever." It means those scenarios have been explicitly tested and passed.

What the buyer would actually need to configure

The purchaser would use their own production accounts/credentials for services such as:

• Stripe Connect
• PostgreSQL
• Redis
• S3/R2
• Resend
• Twilio
• Sentry

The technician application is a mobile-optimized PWA, not native iOS/Android apps.

Why I'm selling

I think the technology is far enough along that someone with an existing plumbing/HVAC/field-service distribution channel could get considerably more value from it than I will by continuing to build infrastructure.

I'm more interested in finding someone who can actually commercialize it than trying to maximize the last dollar of the sale.

Asking: $23,000 USD for the complete software asset + IP, subject to a proper asset purchase/IP assignment agreement.

Serious buyers can conduct repository-level technical due diligence before closing.

If you're building in field service, plumbing, HVAC, electrical, or vertical SaaS, I'd genuinely be interested in hearing what you think this is worth.

Hey r/SideProject,

I built a completely custom, enterprise-grade luxury e-commerce storefront. I am selling the 100% exclusive rights, complete source code, and the live Vercel environment. Once sold, this is off the market forever and you own the copyright completely.

\*\*Tech Stack:\*\* Next.js 15 (App Router), React, Prisma, SQLite (easily swappable to Postgres for scale), and Tailwind CSS.

\*\*Features:\*\*

\- High-converting glassmorphism UI

\- Fully private Admin Dashboard

\- Bulk CSV inventory upload engine (test this yourself!)

You can check out the live demo here: [https://storefront-pied-phi.vercel.app/\](https://storefront-pied-phi.vercel.app/)

\*(Test the admin panel at /admin with password: admin)\*

I am asking $3,500 for the exclusive transfer of all assets. This is perfect for a developer wanting to convert this into a SaaS platform, or an agency needing a premium e-com boilerplate for high-ticket clients (it's cheaper than paying a dev team for 100 hours of work).

Send me a DM if you are interested in acquiring this!
