The problem with how SMBs handle calls today
Twenty to a hundred inquiry calls a day. No CRM. No system. Just memory.
Missed calls = missed sales
Twenty unsaved numbers a day. Half forgotten by night.
Notebooks don't scale
Paper diaries and sticky notes break the moment two people answer.
Follow-ups slip
Hot leads go cold because nobody remembered to call back.
