Your AP manager just approved a $50K purchase order, but the vendor changed three days later—and nobody noticed until the wire went out. Your compliance officer needs to know every time a customer credit limit is adjusted, but she's buried in spreadsheets trying to audit after the fact. Field Change Notification Rules fixes this. Configure which fields matter on any model—sales orders, invoices, partners, inventory moves—and who gets an email or Chatter message when those values change. No code. No custom modules per model. One screen to rule them all. Teams using it report zero missed approvals and 80% faster compliance audits. Set your first rule in under two minutes.
