The problem it solves

You're spending time every week manually messaging clients who haven't paid, and it's easy to forget someone or send reminders late. Chasing payments feels awkward and eats into time you'd rather spend on the work itself.

Who it fits

Good for freelancers, agencies, or small businesses who bill clients directly and need to nudge slow payers.

How it works

  1. Every morning at 9am the reminder schedule runs
  2. The system builds a list of clients with outstanding amounts and due dates
  3. Each client gets a personalized WhatsApp message with their name, amount owed, and due date
  4. The system logs which reminders were delivered and which failed
What you get

Slow payers reminded every morning without your effort

Each morning your clients get a personalized WhatsApp reminder about their payment, so you never have to chase them yourself.

What you get

A daily log of WhatsApp payment reminders sent to clients, with delivery status for each one.

What you need

A MoltFlow account connected to a WhatsApp number.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
