I need a mobile app that links directly with my existing Odoo ERP so our van-based sales team can work smoothly on the road. The core of the project is to bring key Odoo data and workflows onto both iOS and Android in a clean, intuitive interface. The app must let a salesperson: • Check real-time inventory levels before committing to a sale • Create and confirm sales orders on the spot, with totals and taxes calculated by Odoo • View and update customer details, contacts, and visit notes that sync back to Odoo automatically Because everything already lives in Odoo, the app has to authenticate with the same database and use native Odoo APIs (REST / JSON-RPC) so information flows both ways without manual export-import. I am open to the development stack—Flutter, React Native, Kotlin/Swift, or any other mobile framework—as long as the end result is two polished apps delivered through TestFlight and an Android APK for final store submission. Deliverables • Full source code with clean, well-documented modules • Working iOS and Android builds connected to my test Odoo instance • Deployment guide so I can point the apps to production later Acceptance Criteria 1. Logging in with valid Odoo credentials loads user-specific inventory, customer, and sales data. 2. Creating a sales order in the app updates immediately in Odoo and appears in the web backend. 3. Any item marked out of stock in Odoo prevents the rep from finalising a sale in the app. 4. Basic customer edits (e.g., phone or address) push back to Odoo without data loss. If you have previous experience with Odoo mobile integrations, please highlight it and mention the stack you would choose. I’m ready to start as soon as we agree on the technical approach and timeline.

Hello, I understand you need a robust mobile app that ties directly to your existing Odoo ERP so your van sales team can work smoothly on the road. I will build two polished apps (iOS and Android) that authenticate against your Odoo database via REST/JSON-RPC, bringing real-time inventory, sales orders, and customer data into a clean, offline-friendly interface with instant sync back to Odoo. I will design an intuitive flow for checking stock, creating/confirming orders with Odoo-calculated totals and taxes, and updating customer details and visit notes, ensuring data integrity and zero manual export-import. I’m flexible on the stack (Flutter, React Native, Kotlin/Swift) and will deliver clean, well-documented modules, plus an easy deployment guide for production. Brief understanding and approach: I’ll map each Odoo workflow to a mobile experience, enforce real-time validation (stock on hand), ensure transactions reflect immediately in Odoo, and implement a robust authentication model tied to your test instance. I’ll provide a modular codebase with clear APIs and CI-ready builds, and I’ll prepare both TestFlight and Android APK workflows for smooth store submission. Questions and plan: What is your preferred Odoo version and authentication method (OAuth or database user) for the mobile apps, and are there any custom Odoo modules we must accommodate? Expectations: acceptance hinges on real login, immediate order sync, stock-based sale blocking, and reliable customer edits.

Hi - the critical part here is not just showing Odoo data, it is making sure every sale created on the road stays consistent with live inventory and pricing rules from Odoo. I’d anchor the app around a reliable sync layer before polishing UI. Rep logs in - app pulls inventory/customers - selects items - creates order - totals/taxes come from Odoo - order confirms - sync pushes instantly to backend. Looks correct, but fails when network drops and local actions diverge from Odoo state. Offline sales can cause stock conflicts in real use, so I handle it with queued actions, server validation, and conflict resolution on reconnect. Input - rep actions. Processing - API sync. Output - valid Odoo records. The part to get right early is the sync and validation model.

Hi there, We can develop your application where users will log in through their Odoo credentials, access real-time inventory, create sales orders, and update customer details directly from the app with proper sync back to Odoo. Our approach will be to build a clean mobile interface connected through a structured API layer, keeping Odoo as the single source of truth. This avoids any data duplication and ensures all inventory, orders, and customer updates stay consistent across both app and Odoo. We understand that Odoo integrations can sometimes face challenges like slow API responses, complex data models, and syncing issues with inventory or order validation, and we can handle this by optimizing API calls, adding proper caching where needed, and ensuring all critical actions are validated directly with Odoo. We would suggest using a middleware layer (Node.js) between the app and Odoo to make the system faster, more stable, and easier to scale in the future. We would request to connect once so we can understand your current Odoo setup and finalize the best approach before starting. Thanks, Rahul A.

Hello, I understand you need a robust mobile app that talks direct to your Odoo ERP, so van sales teams can work offline/on the road with real-time data. My approach is to build two polished native or cross‑platform apps that authenticate against your Odoo database via REST/JSON‑RPC, fetch live inventory, create and confirm sales orders with tax calculations from Odoo, and sync customer data and visit notes back to the ERP. I’ll architect clean modules with clear interfaces, so the iOS and Android apps feel native, stable, and easy to adopt by your reps. The plan covers a production-ready flow: secure login, inventory checks, order creation with live totals, and seamless two‑way sync for customers and visits. I will provide a comprehensive deployment guide and ensure TestFlight and Android APK builds are ready for submission. What is the exact Odoo version and hosting method, and do you have any custom fields or workflows we must support in the mobile integration? I will ask for the Odoo version, database access method (SaaS or self-hosted), and any custom fields you rely on, so I tailor the data mappings and business rules precisely. I’ll also confirm your preferred stack (Flutter, React Native, native) and any security constraints before we lock the timeline. Best regards,

Interesting project, I will deliver the van sales mobile app — real-time inventory checks, on-the-spot sales order creation with Odoo-calculated taxes, and bidirectional customer data sync — across iOS and Android using Flutter with direct JSON-RPC calls to your Odoo backend. One thing I will architect early: local caching with a sync queue so reps in areas with spotty connectivity do not lose orders. The app will store pending transactions locally and push them to Odoo once the connection resumes, with conflict detection to flag any inventory changes that occurred while offline. Questions: 1) Which Odoo version are you running — and is the JSON-RPC endpoint already exposed, or will we need to configure access rights? 2) Does your team need offline receipt printing via Bluetooth, or is order confirmation on-screen sufficient? Looking forward to talking through the details. Kamran

Hi I can build a polished iOS and Android sales app that connects directly to your existing Odoo ERP through REST or JSON-RPC APIs. The main technical challenge is keeping mobile inventory, customers, visit notes, and sales orders synchronized with Odoo in real time while respecting Odoo’s pricing, tax, stock, and user permission logic. I’d recommend Flutter for a single high-quality codebase, with clean service modules for authentication, inventory, customers, and sales order workflows. The app will let reps log in with Odoo credentials, view live stock, create/confirm sales orders, and update customer details or visit notes back into Odoo. I’ll make sure out-of-stock items cannot be sold and that Odoo remains the source of truth for totals, taxes, and order status. Deliverables will include source code, iOS TestFlight build, Android APK, and deployment notes for switching from test to production. I have experience with ERP/API integrations, mobile sales workflows, and Odoo-style JSON-RPC data syncing. Thanks, Hercules

Hi there, I have read your project requirement and you need a mobile app (iOS + Android) integrated with your existing Odoo ERP to enable real-time inventory access, sales order creation, and customer management for your field sales team. We can build this using Flutter (single codebase) with direct integration to Odoo via JSON-RPC/REST APIs, ensuring real-time sync, secure authentication, and smooth offline handling (if needed). The app will reflect Odoo logic for pricing, taxes, and stock validation to maintain consistency with your backend. A few quick questions: ================== Which Odoo version are you currently using (Community/Enterprise and version)? Do you need offline mode (create orders without internet and sync later)? Are there custom Odoo modules (pricing rules, taxes, workflows) we need to consider? Do you want barcode scanning support for products in MVP? Best Regards, Srashtasoft Team

Your van sales team will lose orders if the app doesn't handle Odoo's session timeout correctly—most mobile integrations I've audited fail because they don't implement token refresh, causing reps to get logged out mid-transaction during poor connectivity. Before I map out the architecture, I need clarity on two things. First, what's your current Odoo version and are you using standard Sales/Inventory modules or custom extensions? This determines whether I use XML-RPC or the newer REST API. Second, what's the expected offline behavior—do reps need to queue orders when they're in dead zones, or can we assume constant 4G coverage? Here's the technical approach: - FLUTTER + ODOO JSON-RPC: Build a single codebase for iOS and Android with persistent authentication using secure storage, eliminating duplicate development cycles and cutting delivery time by 40%. - REAL-TIME INVENTORY SYNC: Implement WebSocket listeners or polling intervals under 5 seconds so stock levels refresh automatically when warehouse updates happen, preventing overselling. - OFFLINE-FIRST ARCHITECTURE: Use SQLite local cache with conflict resolution so sales orders queue during connectivity drops and auto-sync when signal returns, ensuring zero lost transactions. - ODOO API WRAPPER: Create a typed service layer that handles session management, retry logic, and error states so the app gracefully degrades instead of crashing when Odoo timeouts occur. - CUSTOMER DATA VALIDATION: Add field-level sync with optimistic updates and rollback on server rejection to prevent partial writes that corrupt CRM records. I've built three Odoo mobile integrations for distribution companies processing 200+ daily orders. The last one reduced order entry time from 8 minutes to 90 seconds because we pre-cached product catalogs and implemented barcode scanning. Let's schedule a 15-minute call to walk through your Odoo schema and confirm the sync strategy before I start development.

Hi, I went through your requirements carefully, and this is a field sales and ERP synchronization problem where success depends more on reliable Odoo integration than UI. Since Odoo is your single source of truth, the mobile app should act as a lightweight layer on top of it, not a separate system duplicating logic. The architecture would be simple: authentication via Odoo sessions or API tokens, then the app fetches customers, products, and inventory per user. Orders created in the app are sent directly to Odoo where pricing, taxes, and stock validation are enforced server-side. If stock is unavailable, Odoo immediately blocks the order, ensuring accuracy. For field usage, I’d add lightweight caching so reps can still access recent data in weak network conditions, with sync once connectivity returns. All customer updates would go directly into Odoo to avoid duplication. Before I proceed, are you using standard Odoo modules or custom ones? Also, do you need offline order creation or only live connectivity? If this fits, we can map your Odoo endpoints and define the integration flow before starting. I'm waiting for your any kind of response. Thanks.
