Modern accounting system combining bookings, invoices, messaging, and blog in one place for better client communication.
Księgowania is a digital accounting system developed for a bookkeeping office in Kraków. It unifies all workflows — from online consultations and invoices to client messaging and a company blog — into one secure web app.
The client struggled with managing separate tools for booking, invoices, and communication. The goal was to centralize operations and make accounting fully digital — easy to manage for the office and intuitive for clients.
The system offers:
It automates repetitive processes and streamlines communication. Clients can instantly send invoices or messages, while administrators track everything in real time — no more lost emails or missed appointments.
Built with Next.js, Node.js, Prisma, and PostgreSQL, the app ensures speed, security, and real-time data updates via WebSockets. Hosted in the cloud for continuous performance.
Communication time dropped by half, invoice processing became automated, and bookings are now handled digitally. The blog and redesigned website helped the company modernize its image and attract new clients.
