Start with what you already have.
If you have a defined design or specification, an OEM conversation can focus on feasibility, production scope, samples and inspection requirements. If the product concept still needs development, an ODM discussion starts earlier: with the intended use, form, functionality and development tasks.
Compare deliverables, not labels.
The terms OEM and ODM are used differently across suppliers. Ask what each proposed scope includes: design work, materials, tooling, engineering changes, samples, tests and production documentation. A service name alone does not establish who owns a design or who is responsible for a particular activity.
Put rights and review points in writing.
Clarify the ownership of drawings, tooling and development outputs. Identify the review stages, who approves changes and which sample becomes the production reference. For connected products, address software ownership and third-party dependencies separately.
Bring a concise project brief.
Include your target market, estimated quantity, preferred format, functional requirements and launch priorities. A model from the catalog can be a useful reference, but it should not replace a written description of your requirements.
General sourcing considerations. The appropriate specification, documents and contractual requirements depend on your product and project.
