When should I stop taking WhatsApp orders by hand?

When orders arrive faster than you can read them. Missed messages, wrong items and two staff replying are the signs to move to a menu link and automatic updates.

• You miss messages at busy times, or find an order hours later.
• Items or addresses are wrong because details were scattered across messages.
• Customers keep asking about prices and where their order is.
• Two staff reply to the same customer, or nobody does.
• Start with a menu link, then add automatic order updates.
