Agents do not take enthusiastically to any non-commission-earning activities, unless they are being paid of course. It is quite common for companies new to working with sales agents to expect them to behave like employees, and expect diligently prepared paperwork (such as credit account forms, references, site surveys, etc) and for reporting to be frequent and of a high standard. Be prepared for resistance to this.
Agents will generally regard reporting as a non-commission-earning activity, and therefore not part of their remit.
You will find that you may have to be prepared to get paperwork completed by head office staff, and for reporting to default to evening verbal reports by phone, where YOU have to call them. Agents may also resist telling you where they have been and who they have spoken to, and particularly where they are going to tomorrow or next week. This they will regard as their business – not yours. They may also not want to give direct feedback on customer reactions and comments.
The only way to guarantee reporting from an agent is to pay him a retainer or fee, and make this conditional on reporting.
