Clients & Suppliers
Clients and suppliers are structured business entities in Darwin. They are not only labels on a project — they carry their own records, files, contacts, and activity history.
Why They Matter
Section titled “Why They Matter”- Project context — each project belongs to a client; suppliers link to the work they quote or supply
- Contact relationships — manage multiple contacts per entity
- Document context — attach relevant documents directly to the entity
- Supplier-specific pricing — associate materials with preferred suppliers
- Bid and commitment traceability — suppliers referenced from bid proposals, commitments, and actual costs
How Suppliers Appear in Workflows
Section titled “How Suppliers Appear in Workflows”Suppliers appear across the request-to-baseline workflow:
- Price lists — supplier prices are recorded in price list items
- Materials — every catalog material requires a supplier
- Bid proposals — submitted proposals include the bidding supplier’s identity
- Commitments — awards reference the committing supplier
- Actual costs — invoices reference the supplier
A supplier is required on a received bid but optional on commitments and actual costs. To substantiate a cost through an invoice reference, provide both its number and supplier unless you attach an evidence document. Record quote dates and references on price lines where applicable.
Best Practices
Section titled “Best Practices”- Keep client and supplier records current with up-to-date contact information
- Attach relevant documents directly to the entity record
- Use structured records instead of relying on external spreadsheets
- Link suppliers to their materials and price lists for traceable pricing
- Review supplier records periodically to ensure accuracy
