Order a handful of your fastest-moving parts (a few screens, batteries and charging ports), inspect and test each one on arrival before installation, track the ship time and packaging, and try one support contact. With no minimum order, as at Parts4Cells, a test order can be as small as you like.
What should you put in a test order?
- Two or three screens for your most common models, for example from iPhone screens or Galaxy A parts
- A few batteries: batteries
- A charging port or two: charging ports
- One consumable you use daily, such as adhesive: adhesives
How do you inspect parts on arrival?
| Check | Pass |
|---|---|
| Packaging | Screens protected individually; nothing loose |
| Labeling | Model and quality tier on each bag |
| Screens | Connect and test before any adhesive: touch, colors, brightness |
| Batteries | No swelling; correct model; packaged for lithium transport |
| Ports and flex | No creases or tears |
How do you judge the result?
Look at four things: was everything in stock as shown, did it arrive when expected, did every part pass testing, and did support answer quickly? If all four are yes, move one product category of volume and review again in a month.
How do you build toward better pricing?
When tiers depend on monthly volume, consolidating orders with one main supplier moves you up faster than splitting across several. Track your monthly spend so you know when you are close to the next tier.
