Celerp

Celerp is a software publisher focused on delivering an integrated enterprise resource planning solution for small and medium-sized organizations that prefer to retain full control over their business data. Its flagship product, Celerp, is a free, self-hosted ERP application that consolidates the core operational functions of a company into a single local-first platform. Rather than relying on external cloud services, the software runs on infrastructure owned and managed by the user, making it a practical choice for businesses with strict data privacy requirements, limited internet connectivity, or a preference for avoiding recurring subscription costs. The product range spans several typical business software categories. Inventory management features support stock tracking, warehouse organization, and product catalog maintenance, while invoicing tools handle billing, quotations, and customer payments. The manufacturing module addresses production planning, bills of materials, and shop-floor workflows, which is particularly relevant for small manufacturers and workshops. Integrated accounting capabilities cover ledgers, expenses, and financial reporting, reducing the need for separate bookkeeping software. A built-in CRM component rounds out the suite by managing contacts, sales pipelines, and customer relationships. Typical use cases include retailers and wholesalers coordinating stock and sales, manufacturing businesses tracking materials through production, service companies issuing invoices and monitoring receivables, and startups seeking an affordable alternative to commercial ERP platforms. Because the application is local-first, it also suits distributed teams or remote sites that need reliable access to business records without constant connectivity. By combining these categories in one cohesive system, Celerp enables organizations to streamline administration, eliminate duplicate data entry across departments, and maintain a unified view of operations from a single, self-managed installation.
