Upflow and Pennylane are building the financial infrastructure of tomorrow. With Pennylane as the single source of truth for finance and Upflow as the Financial Relationship Management (FRM) layer for cash collection, modern finance teams can finally unify their data, automate key workflows, and strengthen customer relationships, all without adding complexity.
Pennylane already powers accounting and financial operations for thousands of SMEs across Europe. By adding Upflow’s dedicated AR and collections workflows on top, finance leaders can extend Pennylane’s capabilities to improve DSO, reduce bad debt, and unlock working capital for growth.
And Pennylane puts it into practice themselves, by managing their own AR through Upflow.
A Native Integration You Can Trust
Unlike third-party connectors or middleware tools, Upflow provides a native integration with Pennylane through an official partnership. This ensures a seamless experience that is secure, reliable, and fully supported – meeting the highest technical standards.
- Reliable data syncs: Start with a complete initial sync that imports your full AR history and builds a strong foundation. From there, Upflow runs incremental, sync in real time, processing only new or updated records to maintain accuracy and eliminate discrepancies.
- Comprehensive data coverage: Customers, contacts, invoices, and credit notes are synced from Pennylane into Upflow, giving you the essential financial foundation for effective collections.
- Built for collections: While Pennylane remains your financial source of truth, Upflow is where you fully manage collections workflows, customer communications, notes, and follow-ups - ensuring flexibility while keeping data integrity intact.
- Enterprise-grade security: Protected by SOC 2 Type 2 certification, the integration guarantees compliance and security. All financial data is encrypted and safeguarded at every step.
With the technical foundation in place, here’s what finance teams can achieve once Pennylane and Upflow are connected.
