Sales, applications, service and product people at brands, OEMs and channel partners. Your name, your expertise, and a profile that moves with you.
Never GST. That belongs to your company, and this account is you — which is the whole reason it survives a change of employer.
A brand or channel partner sells from a SuperStore with a catalogue and a lead board. You link to it, and keep a profile of your own alongside it — so a printer can follow the company and the person separately.
