CrescentOne C1 vs ERP5

CrescentOne C1 has no write-up on Specifiction yet; its figures are above.

ERP5 is a free, open-source business platform covering CRM, production management, supply chain, product design, accounting, human resources and e-commerce. Its listed modules include finance, inventory, order management and manufacturing, with support for multiple entities. The system can be used and configured in a web browser, and the maker says all browsers are supported. Organizations can also run a preconfigured ERP5 virtual machine on their own server. That VM package is not recommended for large production environments with many users or for development; the maker recommends SlapOS for production deployments and complex integrations. ERP5 is written mostly in Python and uses the NEO transactional NoSQL database alongside a relational SQL database, with MariaDB preferred. It provides a HATEOAS JSON API and an MCP implementation that can expose read-only or read-write services. ERP5 uses role-based permissions configured by module and document. The maker says it is intended for organizations prepared to supervise deployment or learn the platform in depth. ERP5 is free to download and use under GPL v2.
