When a new contact messages your number, LedgerOS creates a party entry automatically with their name and number. No manual data entry. Every enquiry becomes a lead in your system, ready to bill when they place their first order.
Every evening, LedgerOS sends you a WhatsApp message with your day's numbers -- total sales, collections received, outstanding created, and any overdue amounts above your threshold. Know your business before you sleep.
Customers message your number: "How much do I owe?" or "Send my last invoice." LedgerOS reads their outstanding from your ledger and replies automatically. No staff needed to answer routine queries.
