Ai sales booster

Mujhe ek AI Voice Calling SaaS MVP develop karwana hai, initially sirf e-commerce COD order verification ke liye. Core flow 1. Merchant apna Shopify store connect kare. 2. Shopify par COD order place hote hi webhook hamare system ko order details bheje. 3. System automatically customer ko AI voice call kare. 4. AI customer se: - Order confirm kare - Customer name/order amount verify kare - Delivery address confirm kare - Cancel karna hai ya nahi pooche 5. Agar customer order confirm kare, AI bole: “Agar aap online payment karte hain to aapko ₹XX discount milega. Kya main payment link WhatsApp/SMS par bhej doon?” 6. Customer YES bole to payment link generate/send ho. 7. Payment successful hone par order ko Shopify mein prepaid mark/update karna ho. 8. Customer cancel kare to Shopify order cancellation/update ho. 9. Har call ka result dashboard mein save ho. Merchant Dashboard Dashboard mein: - Total COD orders - Calls attempted - Calls answered - Confirmed - Cancelled - Address issue - Prepaid converted - Failed calls - Call duration - Call recording/transcript (where legally permitted) - Estimated RTO saved - Prepaid conversion rate AI Initially: - Hindi - Hinglish - English AI ko fixed business rules ke according kaam karna hai. Open-ended AI nahi. AI conversation ka result structured format mein database mein save hona chahiye: confirmed / cancelled / prepaid / address_issue / callback / no_answer / other Tech preference Frontend: Next.js Backend: Node.js/TypeScript Database: PostgreSQL/Supabase Workflow: n8n ya custom backend Shopify: Shopify Admin API + Webhooks Payment: Razorpay Voice: suitable Indian-compliant voice/telephony API LLM/STT/TTS: suitable production APIs Important: telephony aur AI voice infrastructure initially existing APIs se use karo. Khud voice infrastructure mat build karna. Important requirements - Multi-tenant SaaS architecture - Har merchant ka data isolated - Secure API keys - Authentication - Role-based access - Webhook security - Retry system - Call failure handling - Rate limits - Logs - Basic billing architecture - Admin panel - API documentation MVP mein abhi ye mat banana: - Real estate module - Healthcare module - Mobile app - Blockchain - Complex CRM - Advanced analytics - Custom AI model Pehle COD product working aur reliable chahiye. Mujhe development start karne se pehle ye 5 cheezein do: 1. Complete architecture 2. Exact third-party APIs/services 3. Monthly running cost estimate at 1,000 / 10,000 / 100,000 calls 4. Development timeline 5. Fixed MVP development cost Aur code modular/scalable hona chahiye taaki baad mein real estate aur healthcare voice workflows add kiye ja saken.
