Build AI Accounting SaaS Platform

Project Title: Full-Stack Developer Needed for AI-Powered Accounting Web Application
​Project Overview
We are looking for an experienced full-stack developer or team to build a web application with integrated AI capabilities. The application should be inspired by the core logic, speed, and minimalist user experience of platforms like simeron.ai, but built with our custom branding, specific use cases, and distinct features.
​Specifically, our application will function as an AI-powered accounting and invoicing platform for freelancers and small businesses. Users will be able to upload or scan invoices and receipts, while the AI automatically extracts the data and categorizes expenses/income. Users can also generate professional invoices and connect securely to external financial APIs (such as local tax authorities or bank feeds) to synchronize their accounting data. The goal is to eliminate manual data entry by using AI for document parsing and automated categorization.
​User Flow
The application must provide a seamless and fast experience from start to finish:
​User registration and authentication.
​Clean, distraction-free dashboard for uploading financial documents (receipts/invoices) or inputting accounting data.
​Rapid processing of the documents via an AI/OCR API to extract data and categorize it.
​Clear display of the extracted data with options to verify, edit, save, or export to accounting formats.
​Core Features Required
​Authentication System: Secure login using Email/Password and OAuth (Google).
​User Dashboard & Database: A secure database to save and display previous user sessions, uploaded documents, generated invoices, and categorized financial data.
​AI & OCR Integration: Seamless connection to an LLM or document parsing provider (e.g., OpenAI Vision, Anthropic, or AWS Textract) to process user uploads.
​External API Connections: Architecture capable of connecting with external tax authority APIs (like myDATA in Greece) and Open Banking APIs for data synchronization.
​Subscription Management (Optional but preferred): Integration with a payment gateway to manage premium tiers and usage limits.
​Proposed Tech Stack
You may propose your preferred framework, but we expect the use of modern, scalable technologies.
​Frontend (React.js, Vue.js, or Next.js): To build a fast, responsive, and modern user interface.
​Backend (Node.js, Python, Supabase, or Firebase): To manage users, secure API keys, and handle complex database operations.
​AI Engine (OpenAI API, Anthropic - Claude, Document AI): The core processing engine for data extraction and automated categorization.
​Payments (Stripe or PayPal): For handling subscriptions and automated billing.
​Project Milestones & Payment Structure
The project will be divided into the following deliverables:
​1. UI/UX Mockups: Delivery of interactive wireframes (e.g., in Figma) for approval before development begins.
​2. Minimum Viable Product (MVP): A functional build featuring successful user authentication, the core AI document parsing loop, and basic data categorization.
​3. Testing & Optimization: Debugging, handling edge cases, and ensuring API rate limits and accuracy of the AI extraction are optimized.
​4. Final Handover: Full deployment to our servers, alongside the transfer of all source code, documentation, and intellectual property rights.
​To Apply:
Please share examples of previous SaaS, AI, or accounting applications you have built, your proposed tech stack for this project, and an estimated timeline for the MVP.
