InvoiceGunFull-Featured Billing & ERP System
The Challenge
Growing businesses were forced to pay for and manage multiple disconnected tools across finance, supply chain, HR, manufacturing, and CRM — creating data inconsistencies, integration headaches, and significant operational overhead with no single source of truth.
The Engineering Solution
We built InvoiceGun as a production SaaS ERP system covering all major business operations in a unified platform. The system automates invoice generation, supply chain tracking, HR workflows, manufacturing management, and CRM — delivered as a fully managed cloud application at invoicegun.com, hosted on DigitalOcean with CI/CD deployments and automated database migrations.
