EasyEDA automatically generates Bill of Materials (BOM) information from the part number and default package information for each part that is placed in a schematic.
It is easy to extend this information to include things like a supplier, a supplier's part number and a description.
#### Here's how:
Add a supplier to the `Custom Attributes` for each part in the schematic by clicking on the `Unknown` field next to `Supplier` and then selecting a supplier from the drop down list:

and then adding a supplier part number or order code:

Next add a Manufacturers part number:

More `Custom Attributes` such as Description can be added by clicking on the `Add new parameter` green plus sign:

Then fill in the fields (tick `In BOM:` if you want this information to appear in the BOM, If `In BOM` is not ticked, the information entered into this new parameter will appear against the part in the schematic but will not be listed in the BOM).

Then click `OK`.
The end result will look like this:

Other information such as a url to a datasheet, alternative parts or a brief note about assembly can be added in the same way with the `In BOM` tick box determining what is just shown in the schematic and what is included in the BOM.
Finally, to access the BOM, do:
**Super Menu > Miscellaneous > BOM report > BOM for Document...**

Then download it in csv format (or in a version tailored for if you have chosen Seeed parts from the SHIFT+F parts search menu):
