Pennylane

Pennylane is a French financial and accounting operating system for SMEs and accounting firms. The Company API (v2) lets companies, firms, and integration partners access and sync invoicing, accounting, banking, and financial data over a REST interface, and automate end-to-end workflows. V2 is the stable version; V1 is deprecated. All amounts are in EUR and the platform is built around French accounting (FEC exports, Plateforme Agréée e-invoicing, SEPA/GoCardless mandates).

Pennylane publishes 12 APIs on the APIs.io network, including Customer Invoicing API, Supplier Invoicing API, Accounting & Ledger API, and 9 more. Tagged areas include Accounting, Invoicing, Fintech, Financial Data, and Banking.

Pennylane’s developer surface includes authentication, changelog, sandbox, documentation, getting-started guide, support, signup flow, and 31 more developer resources.
