All-in-one business management platform for solo entrepreneurs
Midday consolidates time tracking, invoicing, financial reconciliation, and secure document storage into a single platform built for freelancers and consultants.
Midday is a comprehensive business operations platform designed specifically for freelancers, contractors, consultants, and solo entrepreneurs. It eliminates the need to juggle multiple tools by integrating essential business functions into one cohesive system.
The platform centers around live time tracking with project insights, automated financial reconciliation through Magic Inbox that matches receipts to transactions, and a secure Vault for contracts and agreements. An AI-powered Assistant analyzes spending patterns and surfaces documents on demand, while seamless CSV export streamlines accountant collaboration. Invoicing capabilities enable real-time collaboration on web-based invoices with project synchronization.
Built as a TypeScript monorepo using Next.js, React, and Supabase, Midday leverages modern infrastructure including Vercel for hosting, Trigger.dev for background jobs, and multiple banking integrations (GoCardLess, Plaid, Teller) for comprehensive financial connectivity across North America and Europe. The architecture supports web, desktop (Tauri), and mobile (Expo) deployments, ensuring accessibility across devices.
When teams consider Midday, these hosted platforms usually appear on the same shortlist.

Automated Expense Reconciliation
Magic Inbox matches emailed receipts to bank transactions automatically, eliminating manual bookkeeping and reducing month-end reconciliation time.
Multi-Client Time Tracking
Freelancers track billable hours across projects in real-time, generating accurate project overviews and facilitating transparent client collaboration.
Financial Pattern Analysis
AI Assistant surfaces spending trends and cost-cutting opportunities, helping solo entrepreneurs optimize cash flow without hiring accountants.
Centralized Document Management
Vault stores all client contracts and agreements in one secure location, enabling instant retrieval during negotiations or audits.
Midday integrates with GoCardLess for European banks, Plaid for US and Canadian institutions, and Teller for additional US bank connectivity.
Invoicing is listed as an upcoming feature that will enable web-based invoice creation with real-time collaboration and project synchronization.
Midday is released under AGPL-3.0, which requires any modified versions distributed to users to also be open-sourced.
Yes, though it requires configuring Supabase, multiple banking APIs, AI services (Mistral/Gemini/OpenAI), and other third-party integrations detailed in the architecture.
Midday supports web browsers via Next.js, desktop applications through Tauri, and mobile devices using Expo for cross-platform coverage.
