TG bot + Google Sheets Points Tracking System

We are looking for a developer to build a simple points tracking system using messaging bots and Google Sheets. Project Overview We need a system that allows authorized users to award and deduct points through a messaging bot, while automatically updating balances in Google Sheets. The system will use: * One shared Google Sheet * Two messaging bots connected to the same sheet * Automated balance calculations * Transaction history tracking * Access control for different user groups Bot #1 Can only deduct points. Bot #2 Can both award and deduct points. Main Requirements * Create and configure two bots. * Connect both bots to a single Google Sheet. * Automatically record all transactions. * Automatically calculate current balances. * Maintain a complete transaction history. * Prevent accidental duplicate transactions. * Allow users to view current balances. * Allow users to view recent transactions. * Set up access permissions for authorized users. The input format can be either: * Free-text messages processed with AI, or * A structured command format if it simplifies development and improves reliability. We are open to the developer’s recommendation. Preferred Skills * Bot development * Google Sheets API * Make.com, n8n, Zapier, or similar automation platforms * Python, Node.js, or similar technologies * Experience building workflow automation systems Deliverables * Fully working bot system * Connected Google Sheets system * Automated balance calculations * Transaction logging * Access control configuration * Documentation and instructions for administrators When Applying Please include: 1. A brief description of how you would implement this system. 2. Whether you would use Make.com/n8n or custom code. 3. Estimated timeline. 4. Estimated cost. 5. Examples of similar automation projects you have built. We are looking for someone who can recommend the simplest, most reliable solution rather than over-engineering the project.
