How I Launched my own micro SaaS

Flare is an AI-powered business management platform that automates document processing and invoicing. Born from the frustration of manual paperwork and the need for intelligent automation.

Reduced bookkeeping task from 15h hours to 45 minutes and it costs cents to run.

Challenge

Small businesses and freelancers waste countless hours on manual document processing and administrative tasks.

Freelancers and small business owners spend 10-15 hours per week on paperwork - manually extracting data from receipts, creating invoices, and managing client information. This manual process is not only time-consuming but also error-prone, leading to inconsistent financial records and delayed payments.

The lack of automated solutions tailored for small businesses creates a significant barrier to scaling operations efficiently.

Results

Flare transforms business administration through intelligent automation and centralized management.

Our platform eliminates manual data entry by automatically extracting structured information from uploaded documents using AI.

Users can process invoices, receipts, and business documents in seconds rather than minutes, while maintaining accuracy and creating comprehensive financial records for tax compliance and business insights.

Process

Research & Technical Architecture: I analyzed the pain points of manual document processing and designed a comprehensive tech stack using React 18, TypeScript, and Supabase for scalable development.

The architecture includes AI processing pipelines with OpenAI integration and robust user management.


Feature Development: Built core functionality including AI-powered document extraction, professional invoice generation, client management with guest access, and financial analytics. Implemented multi-currency support with automatic conversion and quarter export functionality for tax compliance.


User Experience Design: Created an intuitive interface using Tailwind CSS and shadcn/ui components, ensuring mobile responsiveness and accessibility. Developed a comprehensive design system with consistent interactions and clear visual feedback for processing states.


Security & Compliance: Implemented Row Level Security (RLS) for data isolation, guest user permissions for stakeholder access, and VAT compliance features. Built comprehensive error handling and validation throughout the application.


Integration & Automation: Developed WhatsApp bot integration for receipt processing, MCP (Model Context Protocol) server for enhanced AI capabilities, and automated email delivery for document exports. Created seamless workflows from document upload to professional invoice generation.

"Building Flare has been an incredible journey combining AI innovation with practical business needs. Every feature was designed to eliminate manual work and provide real value."
