Project Overview

A modern billing and invoicing platform with integrated Cardano blockchain payment support. The application enables businesses to generate invoices, accept ADA/native token payments, track blockchain confirmations, automate accounting workflows, and manage customer billing from a single dashboard.

 

Project Objective

• Designing a billing application with integrated Cardano payment support

• Exploring blockchain-based payment workflows and decentralized transaction handling

• Generate and manage invoices digitally

• Accept Cardano ADA payments directly

• Support Cardano native tokens and stablecoins

• Track blockchain transaction confirmations

• Provide real-time payment status updates

• Generate financial reports and analytics

• Support recurring billing and subscriptions

• Integrate with Cardano wallets

• Maintain secure, auditable payment records

• Future scope includes Ethereum payment integration

​

Project Design Summary

• Designed and architected a blockchain-enabled billing and invoicing platform with integrated Cardano payment support

• Implemented ADA and Cardano native token payment processing with real-time blockchain transaction monitoring

• Integrated CIP-30 compatible Cardano wallets including Lace, Nami, Eternl, and Flint

• Built invoice management system supporting invoice creation, payment tracking, recurring billing, and automated reconciliation

• Developed backend services for blockchain payment verification, address generation, and confirmation monitoring using Blockfrost/Koios APIs

• Implemented QR-code based crypto payments and payment link generation for seamless customer checkout

• Designed secure treasury and wallet infrastructure with support for multi-signature fund management

• Built analytics and reporting dashboards for revenue tracking, payment history, and accounting reconciliation

• Utilized React/Next.js, Node.js, PostgreSQL, Redis, and Cardano SDKs such as Lucid and cardano-serialization-lib

• Designed scalable microservices-based architecture with Docker, Kubernetes, and cloud deployment support

​

Project Upgrade

The system can be extended into a multi-chain billing platform by integrating Ethereum payments alongside Cardano payments.
