Pennylane combines production software for accountants and financial management tools for their clients. It centralizes all financial flows of companies in real-time and streamlines collaboration between businesses and their accounting firms.

With Pennylane, accountants focus on their advisory role, saving time on data entry and document retrieval thanks to numerous platform automations. Meanwhile, businesses can make better decisions and simplify their management. Without leaving the platform, they access all their data, which is reliable, up-to-date, and actionable; they manage payments and billing seamlessly. Launched in 2020 in France, Pennylane supports over 4,000 accounting firms and more than 350,000 businesses of all sizes.
