Capture the item, the serial number and the packing with EverStamp before it goes. An independent service timestamps the file, so if the buyer says it arrived broken, you can show the state it was in when it left.

The marketplace asks about the condition. Two sets of phone photos, neither with a date anyone trusts.
Once the parcel is opened, nobody can see how it was packed.
As a buyer, capture the parcel and the item as they arrive, before you unpack everything.
The Condition at delivery template in the app has three steps: the package, the label and the handover. Capture the item itself under the package step, before and after it goes into the box.
Capture the serial number or the frame number. It ties the file to this item and no other.
Every side, any wear, the serial number, and the item working.
An independent service timestamps the series. It is then fixed that these captures of the state it left in already existed by then.
Send the link to the buyer or the marketplace when a question comes up, or with the tracking number straight away.

Yes. Capture the item at the handover; the file carries the time, and the place if location is on.
The date on an ordinary photo comes from the phone and can be changed afterwards. Here the time that counts comes from an independent service, and the page shows the window from the time anchor to the timestamp.
Basic has no subscription, and your first file is free, with the same seal as Plus.
