Chasing an unpaid invoice is the job nobody wants. It is awkward, easy to delay, and the cost lands in cash flow. We built JustPayMe so the whole chase runs inside WhatsApp. The owner sends a message or voice note, approves with one tap, and a professional reminder goes to the client. The client can reply and pay straight from the chat. No new app, no portal to log into, on either side.
Making a messaging channel trustworthy enough to run money is the real work. The right tone at each step in the cycle, a human approving every send, careful delivery so nobody is chased twice or after they have already paid - that judgement is what the case study is about.
