I need a clean, production-ready BillDesk payment gateway added to the mobile app that sits on my Odoo 18 back-end. The goal is simple: let users pay directly from the app and have each transaction flow back into Odoo so orders and invoices move automatically into their paid state. The work involves: • Creating an Odoo module that handles token generation, checksum/secure hash requirements, and the BillDesk redirect → callback cycle • Building the mobile-side hand-off so the user sees the BillDesk screen in-app, completes payment, and is returned seamlessly with success/failure messaging • Updating Odoo sales orders, invoices, and accounting entries the moment BillDesk confirms a payment • Supplying clear setup notes and a quick test script so my team can replicate the flow on staging before we push to production Everything must be fully tested on the current Odoo 18 codebase. If extra hooks or controllers are required in the app layer, document them; otherwise the finished Odoo module should drop in with minimal code changes on the mobile side. Once you hand over the module, callback URLs, and documentation, I will run end-to-end tests to sign off.

Hi, there I want to be transparent: what you’re describing goes beyond a basic payment integration. Handling BillDesk with Odoo 18 (orders, invoices, payments) and a mobile flow requires proper validation, secure callbacks, and consistency in accounting data. Done incorrectly, it can lead to duplicate or invalid financial records. I can definitely help, but a production-ready implementation (checksum validation, idempotent callbacks, reconciliation, and stable mobile flow) is not realistic within this budget. If you’re open to it, I suggest a phased approach: Phase 1: working BillDesk flow (redirect + callback), basic status update in Odoo, and staging setup Phase 2: security hardening, retry logic, and full accounting reconciliation If the goal is only a quick demo or prototype, we can adjust scope accordingly. If you’re aiming for a reliable production setup, I’m happy to define a proper scope and timeline. Before moving forward: Mobile app framework? BillDesk sandbox ready? Any existing Odoo payment providers? Best regards, Hector

We can implement a secure, production-ready BillDesk payment integration for your Odoo 18 backend with seamless mobile app interaction and automated transaction handling. Our approach includes developing a custom Odoo module that manages the full BillDesk flow—token generation, checksum/hash validation, and secure redirect → callback handling. We will ensure all payment responses are verified and processed reliably within Odoo. On the mobile side, we will enable a smooth in-app payment experience where users are redirected to the BillDesk interface and returned seamlessly with clear success/failure feedback. The integration will be designed to require minimal changes to your existing app. Once a payment is confirmed, the system will automatically update sales orders, invoices, and corresponding accounting entries in Odoo, ensuring accurate and real-time financial tracking. We will thoroughly test the integration on your Odoo 18 environment, covering edge cases and ensuring stability across the full payment lifecycle. Deliverables include the fully functional Odoo module, configured callback URLs, end-to-end tested payment flow, and clear documentation with setup steps and a test script for staging validation. The result will be a reliable, secure, and streamlined payment experience fully integrated with your Odoo system.

Hello There, You want a BillDesk payment gateway for your Odoo 18 mobile app that automates order fulfillment and accounting reconciliation. 1) Have you already obtained your BillDesk Merchant ID and Security Checksum Key for the production environment? 2) Does your mobile app use a specific framework like Flutter or React Native that requires a dedicated API endpoint for the WebView bridge? 3) Should the module handle partial payments or only full settlements against sales orders? We will turn your manual payment tracking into a hands-off automated system that improves your cash flow and customer satisfaction. Your users will enjoy a professional checkout experience without leaving the app, and your finance team will save hours every day as orders and invoices update themselves instantly. This integration eliminates the risk of missing payments or human error, giving you a reliable and transparent financial pipeline that works around the clock. I will develop a custom Odoo 18 module following the payment provider inheritance pattern to manage the BillDesk secure hash validation and redirection logic. The backend will expose a secure controller to handle asynchronous server-to-server callbacks for real-time status updates even if the user closes the mobile application prematurely.

Hi, I’m Sanket, an Odoo developer with experience integrating custom payment workflows and API-based ERP automations. I can help you build a clean, production-ready BillDesk integration for your Odoo 18 environment with proper mobile app flow handling and real-time accounting updates. Here’s how I would approach the implementation: • Develop a dedicated Odoo 18 payment module for BillDesk • Handle: token generation -checksum/hash validation -secure request signing -redirect + callback flow -transaction status verification • Create secure controller endpoints for: -payment initiation -BillDesk callback handling -payment validation responses • Update Odoo automatically after successful payment: -Sales Order → Paid/Confirmed -Invoice → Paid -Accounting entries posted correctly -Transaction logs maintained for audit/debugging • Mobile App Integration: I’ll keep app-side changes minimal by exposing clean API/controller endpoints. If app hooks are required for in-app redirection or callback handling, I’ll document them clearly for your mobile team. • Testing & Handover: -staging environment testing -callback verification -failed transaction handling -retry scenarios -webhook validation -setup documentation -quick testing script for your internal QA I’ll ensure the module is production-safe, properly structured, and easy to maintain for future upgrades.

I see you need a bulletproof BillDesk integration for your Odoo 18 backend that handles everything from secure hash generation to updating your accounting entries in real-time. Since Odoo 18 is quite new, I’ll ensure the module follows the latest payment provider inheritance patterns so it doesn't break during your next minor update. I’ll build the checksum logic in Python, set up the callback controllers to trigger those "Paid" states automatically, and provide a clean bridge for your mobile app to hand off the user to BillDesk seamlessly. As a bonus, I’ll include a dedicated testing suite and Postman collection so your team can verify the end-to-end flow on staging without burning real money. If you need any tweaks or further Odoo customization down the line, I can handle that too so you don’t have to go through the hiring process again. Drop me a message and let's get this integration live.
