I sell mobile phones and other electronic goods through a bricks and mortar store as well as online, I have only recently started using the Linnworks EPOS module in my shop and the one thing I can't do at the moment is record a serial number with the job, I used to do this in the 'Notes' section of Linnworks for orders received online so if it was returned I could search for it to find the order, because sometimes people lose their receipts. So a simple 'Notes' button on the EPOS module would be useful for me and I think many others using the EPOS module.
