Hello, Thank you for confirming the budget. I want to ensure we build a system that is stable, scalable, and genuinely useful for your operations rather than rushing into an overloaded implementation. Based on the project requirements, the complete solution includes multiple independent modules (AI logic layer, RFQ engine, promotions system, automation workflows, admin analytics, etc.), which are typically implemented in structured stages. Within the current budget of $500, we can confidently deliver a strong and production-ready Phase 1, which would include: • WhatsApp Business API integration • Core conversational logic & intent handling • Product search & availability via your platform APIs • Pricing response flow • Basic order / status handling • Essential notification messages • Clean and reliable interaction behaviour This ensures your WhatsApp agent becomes fully functional and usable for real customers. Advanced modules such as: • Smart RFQ workflow & supplier routing • Customer memory & personalization engine • Promotions & targeting logic • Extended automation layers • Advanced analytics / dashboard expansion can be implemented in subsequent phases, allowing proper testing and refinement without compromising system reliability. This phased approach is the standard practice for complex automation systems and protects both performance and user experience. Please let me know if you would like me to proceed with Phase 1. Best regards, Gagan
