Most freelancers juggle a timer app, a spreadsheet, and an invoice tool. BillTick puts all three inside Telegram, where they already spend the day talking to clients. What's different: clients get their own side of the bot — live session status, and they can mark an invoice paid themselves, not just get a PDF blind at month's end. Free plan has no session/client limits. Pro adds custom PDF themes, no watermark, and an AI stats assistant.

Hey — maker here. I built BillTick because I was tired of juggling a timer app, a spreadsheet, and a separate invoice generator just to bill clients, when I already spend the whole day in Telegram talking to them anyway. Along the way, the idea evolved past just "timer + invoice" — clients now get their own side of the bot too, so they're not just receiving a PDF blind at the end of the month, they can see session status live and even confirm payment themselves. That two-sided part turned out to be the thing people notice first. Free plan is genuinely usable long-term, not a crippled trial. Happy to answer anything about how it works.
