Midday is a business management platform built for freelancers, contractors, and solo entrepreneurs who juggle multiple tools just to run their day-to-day operations. Instead of switching between separate apps for invoicing, time tracking, expense management, and file storage, Midday brings everything into one place so you can focus on growing your business. The core things it helps you with are straightforward. You can track time spent on projects in real-time to understand productivity and billing accurately. When invoices or receipts land in your inbox, the system automatically figures out which transaction they belong to, no manual sorting. There's a secure vault for storing important documents like contracts. The assistant feature analyzes your spending patterns and can flag ways to cut costs or help you find documents quickly. And when tax season comes around, you can export all your financial data as CSV files ready to hand off to your accountant. The platform is built as a modern web and mobile application using React, TypeScript, and Next.js. On the backend, it relies on Supabase for the database and authentication, handles background jobs through Trigger.dev, and connects to banks via Plaid, Teller, or GoCardless depending on your location. The whole thing is hosted on Vercel and runs as a monorepo, a single codebase that houses multiple related projects. Midday would appeal to anyone running their own business who's tired of logging into five different apps just to invoice a client, track time, and organize receipts. A freelance designer could track billable hours on projects, automatically categorize expenses from their email, store client contracts in the vault, and generate an invoice, all without leaving the platform. The project has gained traction, with features like invoicing still in development, suggesting the team is actively expanding what the tool can do.
