Runs collections on late invoices: builds an aging ladder (current/30/60/90+), assigns each invoice a rung on an escalation sequence with ready-to-send emails — friendly nudge, firm reminder with late-fee mention, final notice — plus a phone script, tone rules that preserve the relationship, a chase log, and when-to-write-off guidance. Use when the user says "clients haven't paid", "this invoice is 45 days overdue", "write a payment reminder", or pastes an invoice list or AR aging.
