Submitting an ECOS proposal

Introduction to ECOS - The ESA Costing Software

ESA has developed a procedure and an associated tool for calculating and aggregating the price elements of large proposals with multiple contractors in a reliable manner (see When to use ECOS)

The tool is called ECOS, the ESA Costing Software.

With ECOS, the price proposal work can be partitioned through the industrial structure, and the proposals can be generated and passed on to higher levels electronically.

The information presented is conform the ESA standard costing and pricing requirements introduced in the ESA Conditions to Tender, and represented by the ESA PSS-A forms (Procedures, Standards and Specifications). An important feature in this process is the computerized integration of data at successive levels of the contract hierarchy, thus avoiding the onerous task of manual integration of data from several sources, a task that is both time-consuming and prone to errors.

The software package is distributed to companies doing business with ESA free of charge and ESA periodically organises free training courses in ESTEC.

A Self-Training Manual (see links on the right) can also be downloaded together with the installation software or as a stand-alone download at any time.
