# Supplier Management Overview (QMS) Veeva QualityOne Supplier Management allows you to track your supplier parent companies and supplier locations. You can report and track supplier quality processes such as supplier nonconformances (SNCR), supplier audits, supplier corrective action requests (SCAR), supplier change requests, and supplier COA submissions for each supplier parent company and supplier location. Additionally, you can invite suppliers as external users into your QualityOne Vault to collaborate on various supplier-related processes. ## External Collaboration Management {#ecm} External Collaboration Management automates external user access to your Vault using a pool of shared _External User_ licenses provisioned by creation, activation, and inactivation. You can assign an _External Collaborator_ to respond to your request on a particular record and the _External Collaborator_ is notified of the task by a corresponding email message. See Working with External Collaborators for more details. ## Object-Level Comments {#comments} Object-level comments enhance collaboration with internal and external users (such as suppliers). You can work on a single record with internal team members or people outside the organization. Comments allow internal and external users to coordinate by tagging specific members to an object record, notifying the users for collaborative decision-making and discussion. You can add, edit, and delete comments in a single object record. See Using Object-Level Comments for more details. ## Audit Checklists {#audit-checklists} You can ensure your audits address the necessary requirements by using an audit checklist. Use audit checklists to conduct internal and supplier audits to help identify audit findings. You can create, edit, and delete audit checklists and automatically create audit findings when completing and submitting a checklist. If configured, you can also perform audit checklists on an Apple iPad and an Android device. See Working with Audit Checklists for more details. ## Material Verification Checklists {#mv-checklists} You can ensure your audits address the necessary requirements for materials by using a material verification checklist. Use material verification checklists to collect internal and supplier responses for all the hazards that require control for a given material. You can create, edit, and delete multiple material verification checklists as part of a single Audit. See Working with Material Verification Checklists for more details.
## Supplier Portal for Nonconformances {#supplier-portal} You can access QualityOne Supplier Portal to collaborate with vendors. This feature allows you to participate in reviewing and updating nonconformance details and create any related items. See Using Supplier Portal for more details. ## Automated COA Email Intake {#coa-email-intake} You can allow assigned _External Collaborators_ to upload COA files to _COA Inspection_ records by email. This feature removes the dependency of training external users to use Vault so that the external user can directly upload a COA file once it is ready to an existing _COA Inspection_ record. External users can also upload multiple COA files by replying to a Vault email notification. The first valid file is attached to that _COA Inspection_ record, and the subsequent files are attached to a new record each, copying the same field values as the initial _COA Inspection_ record - Vault copies these new records in a similar approach to the _Copy Record_ action. See Working with COA Inspections for more details.
