The Organisations menu is a great source of potential vendors for your project. It contains an extensive collection of profiles of various firms involved in international development.
Widely used when identifying partners and/or conducting market research, organisations' profiles provide general and contact information as well as project references with other donors.
The process of identifying organizations can be streamlined by the use of search filters, accessible by clicking Advanced Filters.
Note: the "With awards in" and "Experience with Funding agencies" filters take advantage of DevelopmentAid's database of Awards, which can be used for an in-depth analysis of vendor's past references.
