BillTick — Time tracking & invoicing

What is BillTick — Time tracking & invoicing?

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.
