FAQ

Common buyer questions about this topic.

Can you start from incomplete files?

Early review can start from partial files, sample photos and project notes, but final production needs confirmed manufacturing data.

Is testing included in the process?

Testing can be planned according to the product function and buyer requirement.

Can the same process support prototype and batch production?

Yes. Prototype and batch production use similar review logic, but batch orders usually need clearer fixtures and inspection records.
