Invoice Generator Bot

Telegram bot for generating professional invoices, tracking payments, sending automated reminders, and managing client billing records with PDF export.

This Telegram-based invoice generator bot streamlines the billing process for freelancers and small businesses by allowing them to create, send, and track professional invoices directly from a chat interface — no accounting software subscription required. Users provide client details, line items with quantities and rates, tax calculations, and payment terms, and the bot generates a polished PDF invoice with their branding that can be forwarded to the client instantly via Telegram. The system tracks payment status for each invoice (pending, partial, paid, overdue), sends automated reminder messages at configurable intervals for unpaid invoices, and maintains a searchable archive of all billing records with summary statistics on revenue, outstanding amounts, and client payment history.
