OEM and EMS customers

Component procurement for manufacturing customers

We help OEM and EMS purchasing teams source specified components for planned production, urgent gaps and continuing product support. The approved parts list, required quantities and build schedule guide the search. We then confirm purchasing and delivery conditions with the relevant customer contact.

We source specified parts for OEM and EMS production and maintenance. Approved part lists, urgent quantities and receiving requirements guide each order, with any change confirmed by the responsible customer contact.

Purchasing support for OEM and EMS requirements

Original equipment manufacturers

We work from the manufacturer’s approved part numbers and production or maintenance plan. Sourcing follows the required quantities and dates, while any proposed change in specification or alternative part is referred to the customer for approval.

Electronics manufacturing services

We follow the end customer’s approved parts list alongside the EMS build schedule. We identify the components needed together, keep delivery status clear by line and refer any unapproved substitution or specification change to the designated contact.

Support where the material plan needs attention

Production situations

Completing a material set

Identify the parts that keep a build from starting and the quantity needed first. Discuss whether an early partial delivery would help while other material follows its existing schedule.

A changed production schedule

When production moves earlier, later or to a different quantity, compare the new need with orders already placed. Clarify which lines need a revised delivery and which remain unchanged.

Longer product support

Older products may continue to need the same parts for manufacturing or repair. Keep the approved full code and document requirements on record, then assess each new source against them.

Clear approval responsibilities for any change

Purchasing, engineering approval and receiving may be handled by different people or companies. At the start of an order, identify who can approve a changed part or condition and what information the receiving team requires.

Vistime provides component procurement support. Product design and approval for the intended application remain with the responsible customer parties.
