Detailed Service Description​

I am selling PayX.gg, an established and operational fintech technology platform and online business.
PayX is not a new or conceptual project. The platform has an existing website, software infrastructure, revenue history, traffic and established card infrastructure.

Business Overview​

  • Asking Price: $20,000 USD
  • Monthly Revenue: $500–$1,000
  • Monthly Website Traffic: 1,000–5,000 visitors
  • Monthly Infrastructure Cost: Approximately $40
  • Current API Cost: $0
  • Domain: PayX.gg
  • Domain Registrar: Namecheap
  • Cloud Infrastructure: Hetzner Cloud
  • Platform Status: Operational

Technology Stack​

PayX.gg is built using a modern web application architecture:
  • Frontend: React
  • Backend: Supabase
  • Database: PostgreSQL via Supabase
  • Authentication: Supabase Auth
  • API: Supabase API / REST
  • Infrastructure: Hetzner Cloud
  • Domain: Namecheap
  • Web Application: React-based frontend
  • Administration: Web-based admin panel

Existing Card Infrastructure​

PayX currently has 7 card BIN programs:
  • 3 Hong Kong BINs
  • 3 United Kingdom BINs
  • 1 United States BIN
Total: 7 BINs
The existing card/BIN infrastructure is part of the current platform setup. Continued use, transfer, assignment and onboarding are subject to the applicable issuer, program manager, financial institution and regulatory requirements.

Technology & Assets​

The acquisition includes the agreed PayX.gg technology and business assets, including:
  • PayX.gg domain
  • Existing website
  • PayX branding
  • React application
  • Supabase backend
  • PostgreSQL database
  • Customer-facing platform
  • Administration panel
  • API infrastructure
  • Existing integrations
  • Wallet-related infrastructure
  • Virtual-card-related infrastructure
  • Existing technical documentation
  • Existing operational infrastructure
The exact source-code and technology transfer scope will be confirmed in the acquisition agreement.

Very Low Operating Cost​

The current infrastructure operates with approximately $40/month in server costs.
There are currently no recurring API fees for the existing API infrastructure.
This gives the business a very low fixed infrastructure overhead relative to its current revenue.
Revenue, traffic and expense figures can be verified during due diligence.

Packages & Pricing​

Complete PayX.gg Acquisition​

$20,000 USD

The acquisition package includes the agreed PayX.gg business, domain, technology and infrastructure assets described above.

Payment Structure​

For additional security and transparency for both parties, the purchase price is divided into two $10,000 milestones.

First Milestone — $10,000​

The buyer transfers:
$10,000 USD
After successful payment:
  • The PayX.gg domain transfer is initiated through Namecheap
  • The buyer verifies successful domain transfer and control

Second Milestone — $10,000​

After the domain transfer has been successfully completed and verified:
  • The buyer transfers the remaining $10,000 USD
  • The Hetzner Cloud infrastructure transfer/handover is initiated
  • The remaining agreed technology and business assets are handed over
  • Technical documentation and operational handover are provided
This staged structure is designed to provide additional protection and transparency for both parties.

Refund Policy​

100% Refund Guarantee

I provide a 100% refund guarantee if the agreed transaction cannot be completed due to an issue on my side or if a material issue prevents the agreed assets from being transferred as described.
If the transaction cannot be completed according to the agreed acquisition terms, the affected payment will be refunded 100%.
The exact transfer scope and refund conditions will be documented in writing before the transaction begins.
Buyers are encouraged to perform appropriate technical, financial, legal and regulatory due diligence before completing the purchase.

Payx.gg has problems with their payment provider - wooshpay.com.

All BINs currently have spending limits - only $20, 30 total and similar thus can't be used for anything worthwhile.

A moderator should check the current state of their platform because it looks like a potential scamy sale.

There are no issues; we're just waiting for the balance to be credited. I believe you've already submitted a payout request; we'll approve payout requests within a few hours.

As long as you’re either addressing the issue or can provide refunds, then it's OK. There have been many scammers on the forum lately—for example, @Kripicard.

Payout requests have been submitted.
The cause of this issue today was that a few of our customers made very large balance top-ups.



Wooshpay does not have a crypto gateway integration.

Top Up < Nowpayments < Wooshpay

Consequently, since we have to process these manually, things don’t always go as planned. We're a startup, so sometimes we have trouble balancing our accounts.
 
OK, please make an official update in your other thread if/once the issue has been resolved.

Thanks.
