It supports multiple e-invoice standards, including XRechnung, ZUGFeRD/Factur-X, Peppol, FatturaPA, and KSeF. By integrating InvoiceIn, businesses can convert these diverse e-invoice formats into a unified JSON structure, simplifying data handling and integration with existing financial systems. A key feature of InvoiceIn is its validation report, which identifies any discrepancies or errors in the received invoices. This report provides clear guidance on necessary corrections, ensuring compliance with relevant standards and reducing the risk of processing invalid invoices. Additionally, InvoiceIn offers multiple output formats, including PDF, CSV, and DATEV, catering to various business needs and facilitating seamless data exchange. The API is designed for ease of integration, allowing businesses to incorporate it into their existing workflows with minimal effort. By automating the processing and validation of e-invoices, InvoiceIn helps organizations improve efficiency, reduce manual errors, and ensure compliance with European e-invoicing regulations. InvoiceIn operates on a credit-based system, where one processed invoice consumes one credit, regardless of the output formats requested. This straightforward pricing model allows businesses to scale their usage according to their needs. Unused credits are refundable within 14 days of purchase if the API was unavailable or unable to process a supported format. Consumed credits are non-refundable. Paid credits do not expire while the API key remains active, providing flexibility and value for users. In summary, InvoiceIn by Peculiar Systems offers a comprehensive solution for businesses dealing with multiple European e-invoice formats. Its support for various standards, combined with validation capabilities and multiple output options, makes it a valuable tool for organizations seeking to automate and streamline their e-invoicing processes.
