What they did
The receptionist marks the quote as sent and the system sends up to three reminders with AI-generated text, stopping when the customer replies.
How it went
In 60 days, approved quotes that went silent dropped from 31% to 9%, at a cost of about R$ 94/month. This is a case told by a consultant, with the owner's name changed.
Good to know
Use the official WhatsApp Business number, offer an opt-out, and don't message people who didn't ask for a quote.
The prompt
Write 3 quote follow-up messages for an auto repair shop: +4 hours, +1 day and +3 days. Customer: [name], car [model], service [x], price [y]. Human tone, short, with a 'not interested' option.
