How do solo service businesses follow up after sending a quote?

Hi everyone — I’m building No Missed Quotes, a lightweight follow-up queue for solo service businesses. It turns a customer, quote amount, and next follow-up date into one clear list of who to contact today, with a message you can copy for WhatsApp, email, or phone.

I’m especially interested in how cleaners, repair pros, designers, photographers, consultants, and small suppliers currently remember to follow up after sending a quote. Do you use a CRM, a spreadsheet, calendar reminders, or just memory?
