Supplier Self-Disclosure: Definition, Template & Tips

A supplier self-disclosure is part of supplier management in purchasing and procurement. It is a method for systematically gathering information about suppliers and their capabilities, and helps you check in advance whether a supplier meets your requirements in specific areas, e.g. quality management. This makes the supplier self-disclosure a quality assurance tool in the supply and ordering process. Depending on its scope, it can take the form of a short online form or a comprehensive online supplier survey. On this page, we explain the term, present our template and share tips on designing and conducting it.

What is a supplier self-disclosure?

A supplier self-disclosure, also known as a supplier self-assessment, is generally used to pre-select and evaluate suppliers, subcontractors or service providers. In it, the potential supplier provides information about their company, including key business figures, product range and quality assurance. This helps companies spot weaknesses in quality assurance, or in a supplier’s general ability to follow the required processes, at an early stage. It is therefore a prerequisite for approving a supplier to deliver to the company. A supplier self-disclosure can also be repeated at regular intervals with existing suppliers to capture the status quo.

A supplier self-disclosure can also form part of the risk analysis under the German Supply Chain Act (LkSG). Companies in Germany that fall under the Supply Chain Act must meet certain requirements and fulfil their due diligence obligations. These include a risk analysis to identify and assess risks along the supply chain. A supplier self-disclosure can provide relevant information for this risk management. You can find more on the Supply Chain Due Diligence Act here: LkSG: requirements, implementation & questionnaires

Supplier self-disclosure template: focus on quality assurance

In most cases, a supplier self-disclosure centres on quality assurance, e.g. information on quality management. Does the supplier have a quality management system (QMS) that is geared towards customer satisfaction and documented? And if so, is the QMS certified? The most widely used standard setting out the requirements for a quality management system is ISO 9001. There are also many industry-specific standards, such as IATF 16949 in the automotive industry.
