Phone Cases Sourcing Checklist: From Enquiry to Delivery
A complete checklist for buying phone cases: defining the requirement, sampling, ordering, production control, inspection, shipping and reordering.

Define the requirement
Start with a one-page specification for phone cases that states material, dimensions, colour, tolerances, packing, labelling and the tests that will be used.
Agree the target price, the target quantity and the delivery window at the same time, so the factory can quote realistically.
Sampling and approval
Ask for at least two sample rounds and approve the final sample in writing, keeping a sealed reference for the production run.
Confirm that the sample uses the same materials and processes as bulk, otherwise the approval is meaningless.
Order and production control
Place a written purchase order that refers to the specification and the approved sample, and ask for progress photos at agreed milestones.
Confirm material arrival and line start dates, because delays are easier to manage when they are visible early.
Inspection and shipping
Book inspection before packing, verify carton configuration and loading, and confirm documents before the vessel departs.
Keep a set of shipping samples so that a future order can be compared against the delivered goods.
After-sales and reorders
Record the defect rate and any customer feedback, and feed both back into the specification for the next order.
A reliable reorder is the real test of a supplier relationship, and it is built from documentation rather than goodwill.
Summary
Used as a checklist during development and again before shipment, the points above prevent the most common and most expensive failures.
