In 2026, are WhatsApp enquiries still handled manually?

Manual notifications slow the team down

  • Order confirmation, payment success and shipping updates still require manual messages
  • Manual sending takes time and can mismatch customer data
  • As order volume grows, admin work grows with it
“

Does your team still send every order update through WhatsApp manually?

Manual notifications slow the team down

After-hours replies are delayed

  • Customers often ask questions after work or during holidays
  • Without preset replies, response delays happen outside office hours
  • Fast replies affect customer experience and conversion opportunities
“

When enquiries arrive after office hours, does the team still rely on manual replies?

After-hours replies are delayed

Plain messages do not convert well

  • Plain-text messages require customers to copy or open links manually
  • There are no one-tap booking, payment or action buttons
  • The longer the path, the fewer customers complete the action
“

After receiving a message, do customers still need to find the booking or payment link themselves?
