OpenProcurement
What it is
OpenProcurement is a free, open-source toolkit for procurement of goods and services by public authorities or private entities. Its components include a Business Process Management engine, central database, API, and auction module. Frontend platforms such as eMalls and marketplaces connect through the API, and can interoperate regardless of their programming language or technology. The auction module supports English, reverse, multivariable, and insider auctions based on a Dutch auction. The central data structure follows Open Contracting Data Standards and publishes information that may be disclosed under applicable law. The toolkit uses Python, Pyramid, AngularJS, Bootstrap, Flask, CouchDB, and PouchDB. Its database and auction module can be hosted on AWS, with SS3-compatible object storage such as OpenStack Swift required. The central database does not store registered users’ authorization data, leaving the web platform or operator responsible for protecting account data. The toolkit is designed without restrictions on database size or procurement volume. Components may be combined or used separately, including to build commercial solutions. The site links to API and procedure documentation, a GitHub repository, and a contact form. Listed implementations include ProZorro, ProZorro.sale, MTender, and RIALTO.
