Our take
In multiple mature markets, companies have been using QuickBooks, Xero and other SaaS solutions for accounting, but it is a fragmented industry with each country using its own software solution. In France, there is no definitive SaaS solution for accounting.
Pennylane wants to overhaul current tools and modernise the tech stack of accounting firms, by connecting directly with third-party services that hold valuable information. Accounting firms can use Pennylane collaboratively by accessing the platform to centralise receipts, create invoices and automate tasks. Instead of sending information back and forth with spreadsheets and photo attachments, both clients and accounting firms can interact directly on the platform.
Pennylane has a significant market opportunity ahead, with an ambitious goal to become the preferred management platform for European companies. The company already claims an impressive number of customers and strong backing which will allow it to further develop its platform and expand to other markets in Europe.
