Billit vs Holodeck B2B

Billit is an invoicing and administration platform for businesses to create and send invoices, track payments, and share documents with an accountant. For Peppol e-invoicing, it converts invoices into the required format and sends them over the Peppol network. Its app scans VAT receipts, and the service recognizes relevant information and amounts from submitted documents. Billit can send automatic reminders for overdue invoices and connects with banks, accounting packages, online shops, cash register systems, and business software. An open API supports custom integrations. The platform is available on Android, iOS, and web, with API access and cloud deployment. A free license covers Peppol sales invoices only and has limited functionality. Paid plans start at €6.90/mo (annual), and a 15-day trial is listed. Monthly document allowances vary by plan; invoices, credit notes, and receipts count toward the allowance, and extra usage is billed when it is exceeded.

Holodeck B2B is open-source software for business-to-business messaging, implementing the OASIS ebXML Messaging 3 and AS4 specifications. It can run as a standalone AS4 gateway or connect with a business system through provided interfaces. The software supports one-way and two-way exchanges using push and pull patterns, including files and attachments up to 2 GB. Gateway monitoring is available through command-line and graphical interfaces. A file-based backend is included; REST API integration is an extension, and the API can be used to build custom backends such as Web Services and JMS. An open-source AS2 extension lets a gateway exchange both AS2 and AS4 messages, with protocol selection in the P-Mode. Listed security features include signing and encryption with WS-Security 1.1.1, certificate trust stores, OCSP checks and AS4 non-repudiation of receipt. Version 7.0 is released under GNU GPL 3, and the software runs on Linux, macOS and Windows. The binary package does not include Java and requires JRE 11 or later.
