Lead sources
A source tells you where a lead came from. Make one for each expo, event or campaign.
Create a source. In your account, open Lead sources and add one. Choose the name with care: it cannot be changed later.
Make it active. Your team can pick it in the app as soon as you save it. Choose it as your active source before you scan.
Scan. Every card you capture carries that source tag, even offline. With the connector, ERPNext gets it too. Connect ERPNext
