Here's the suggestion:

This is from pcbway shared projects (similar to oshwlab for jlcpcb)

Project link: Decorative skull led

Having a simple "Add to cart" button would be nice.

It should have the same function as the Reorder button which automatically adds to the cart along with the previously used settings.
I could link my order number in oshwlab which takes care of the pcb and pcba specifications for jlcpcb.

Current workflow:

I advise my members to order from the easyeda, using the Order PCB option. It automatically uploads all the files (gerber, bom, pickplace).

Then they have to adjust all the specifications according to my instructions.

Many are new to this, They are not electronics engineers or pcb designers. They are more prone to order the wrong PCB configuration.

Here's one of my member who ordered the bare PCBs without the PCBA, he had to order the assembled boards again.

Well, he won't repeat that mistake again. But back to our point

Better Workflow:

It would be extemely beneficial to both the users and jlcpcb if we had an Add to cart button similar to pcbway

P.S: pcbway shares 10% of order amount to the project author.
But I still recommend jlc because of the good price and fast turnaround time especially for the assembled boards.

Update March 2025:

Creators who are selling the PCBs/Kits can now have their projects listed in the Oshwlab market - This is a good initiative by the Oshwlab Team.

These listed projects will have a "Buy now" Button in the project page.

The button can be linked to the website where the creator is selling - such as aliexpress, alibaba, amazon, elecrow, etc
