- Problem
- Freelancers and small teams create invoices late, chase payments in chat threads, and lose track of which project is paid, queued or overdue — especially when work starts from a WhatsApp or Slack message instead of a billing tool.
- Solution
- PaperChai Invoice turns everyday messages into billing ops. Send a request via WhatsApp, Slack or a normal message to the bot — it creates the invoice, queues it, tracks payment status, sends reminders in your tone, and keeps project billing visible so chasing clients stops being a spreadsheet job.
- What it does
- Create invoices from WhatsApp, Slack or chat messages
- Queue invoices and keep project billing status clear
- Track who paid, who delayed and what's outstanding
- Smart email + WhatsApp reminders
- Dashboard for outstanding, paid and reliability signals
- Challenges
- Parsing messy natural-language billing asks into clean invoice data, syncing across chat channels without duplicate invoices, and making reminders feel personal — not spam — while payment status stays reliable.
- Result
- A money-autopilot surface where invoice creation starts in the tools people already use, and payment tracking / reminders run without a second admin job.
