Hello! As per your project description, you are looking to build an B2B Ordering Platform consisting of native iOS and Android apps, a web application, web administration panel, and REST API backend, all connected with your existing ERP. The platform will support offline order taking, SMS based user access, customer specific pricing, commercial discount policies, approval workflows, B2B reporting, push notifications, and bidirectional ERP synchronization. My focus will be on creating a reliable B2B ordering workflow where users can browse products, work offline when required, create orders, submit them for approval, and automatically synchronize everything once connectivity is restored. The administration panel will provide centralized control over customers, products, orders, pricing policies, discount rules, and approval processes. I specialize in B2B e commerce platforms, native and cross platform mobile applications, offline first workflows, ERP integrations, REST APIs, product and inventory synchronization, customer specific pricing, approval workflows, push notifications, and scalable backend systems. Let’s connect to discuss your existing ERP, B2B ordering process, offline requirements, commercial policies, and synchronization workflow so we can design a reliable system that streamlines your entire order management process.

Your ERP sync strategy will determine whether this system scales or becomes a maintenance nightmare. If you're pushing orders back to the ERP without idempotency keys and conflict resolution logic, you'll face duplicate transactions and data corruption when the API retries fail. Quick questions - what ERP platform are you integrating with (SAP, NetSuite, custom system)? And what's your expected transaction volume during peak ordering windows? Here is the architectural approach: - OFFLINE MODE: Implement SQLite local storage with conflict resolution algorithms that merge offline orders when connectivity returns without duplicating records in the ERP. - ERP INTEGRATION: Build a middleware layer with retry queues and webhook listeners to handle bidirectional sync failures, ensuring inventory updates don't overwrite pending B2B orders. - NATIVE APPS: Use Swift/Kotlin with shared API contracts to maintain feature parity across iOS/Android while keeping the codebase maintainable as your product catalog grows. I've built similar B2B platforms for 2 wholesale distributors processing 500+ daily orders with zero sync errors. Let's schedule a 20-minute technical call to map your ERP endpoints before development starts.

Dear Client, I read "B2B E-Commerce Apps With ERP" carefully and understand you need a B2B website built for how businesses actually buy — bulk orders, quotes and account-based pricing. My hands-on experience with PHP, Mobile App Development, Android, ERP, Web Development, API Development aligns directly with what you need. I've built B2B portals with tiered/bulk pricing, quote requests, account hierarchies and streamlined bulk ordering — professional, fast and built to handle business buyers, not just retail shoppers. A few quick questions to get us started: 1. Do you need customer-specific or tiered pricing? 2. Will buyers place orders directly, or go through a request-for-quote flow? 3. Do you need multiple user roles per business account (e.g. buyer, approver)? Thanks & Regards, Deepak

Offline-first ordering with bidirectional ERP sync is the hardest part of this project to get right, and it's where most B2B apps break down silently. I'll build the mobile apps in React Native with a local SQLite layer for offline order-taking that queues and syncs automatically on reconnect. The web admin panel and API will run on Node.js, handling approval workflows, custom price lists per customer, and the scheduled ERP sync via RESTful endpoints plus FTP for product photos. One thing worth flagging early: bidirectional sync needs conflict resolution rules, especially when inventory levels change in the ERP while a sales rep is taking orders offline. I'll design a last-write-wins strategy with manual review flags for quantity conflicts. 1) Which ERP system are we integrating with, and does it already expose a RESTful API? Happy to talk details in chat. Shayan
