X7.ee is a business software brand operated by X7 Systems OÜ, based in Tallinn, Estonia. It provides a unified workspace designed for freelancers and small teams, bringing invoicing and everyday business operations together in one system. Users can create one-off and recurring invoices, prepare price quotes, and send and receive e-invoices through PEPPOL and Estonia’s e-invoicing infrastructure. The platform also includes service and product catalogs with stock, cost, and margin tracking; expense management for receipts and supplier documents; and project tools for tasks, time logs, and related invoicing.

Additional modules combine email, web chat, and client requests in a shared inbox, while a knowledge base organizes company files and guides with AI-powered search. X7 describes AI features that help triage email into tasks, extract information from supplier documents, and match payments with bank data. The service offers PDF invoices, bank statement import, and a REST API, alongside data backups, configurable team and accountant permissions, encryption, two-factor authentication, and activity logs.
