I need a clean, reliable bridge between my mobile and Tally so that product, party and invoice data stay perfectly in sync. The integration has to work both ways: my app must be able to push freshly-created records into Tally, and it must be able to pull any updates or new entries back out again for real-time use. The focus is strictly on those three datasets—products, parties and invoices—nothing else for now. I am open to whichever technical route you find most stable, whether it involves TallyPrime’s XML interface, TDL customisations, ODBC, a lightweight REST layer or a hybrid of these. What matters to me is that calls from the app return the expected JSON quickly and that writes land in Tally without manual intervention. Acceptance criteria • End-to-end demo showing bi-directional sync of one product, one party and one invoice. • Clear setup notes so I can reproduce the connection on another machine. • Source code or scripts documented well enough for my internal team to maintain. If you have proven experience integrating Tally with mobile stacks, I’d like to see an example build or brief walkthrough of how you handled authentication and error handling.

Hello, I checked your requirement for a bi-directional Mobile ↔ Tally integration covering Products, Parties, and Invoices. It is doable. Please connect on chat to discuss your mobile application stack and Tally version. ✔ I can build a reliable synchronization layer between your mobile application and TallyPrime using Tally XML APIs, TDL extensions, ODBC, or a hybrid approach depending on your environment and performance requirements. ✔ The integration will support: • Product sync (create, update, fetch) • Party/customer sync (create, update, fetch) • Invoice sync (push and pull) • JSON-based API responses for mobile consumption • Real-time or scheduled synchronization • Error logging and retry mechanisms • Validation to prevent duplicate records • Secure API communication and authentication ✔ My preferred approach is to expose a lightweight REST API layer that communicates with Tally through XML APIs. This provides cleaner mobile integration, easier maintenance, and better scalability for future modules. ✔ Two Queries: 1. Which Tally version are you currently using (TallyPrime, Tally ERP 9, etc.)? 2. Is the mobile application built with Flutter, React Native, Android Native, or another technology? ✔ Note: I will provide complete source code, setup documentation, and an end-to-end demo showing successful bi-directional synchronization of products, parties, and invoices as requested. Warm regards, JP

Hi! Your focus on bi-directional sync for products, parties, and invoices with Tally is the smart move — syncing just these three covers nearly every core business flow without getting bogged down in the less-used modules. Making sure each push and pull works with zero manual steps is usually the stumbling block in Tally integrations. I set up a similar bridge between a React Native app and Tally for a retail ERP last year, combining the XML interface for posting and a wrapper API for real-time JSON reads. Most of the pain came from handling ID mapping and Tally’s session quirks, so I made all error paths obvious and retriable. One question — do you already have remote access set up for Tally (like Tally running as a networked service), or will I need to plan for local deployments as well? Happy to share a sample sync flow and annotated scripts for your review, no strings. You can check out other integrations I’ve handled at work.techindika.com. — Pradeep

As a Backend Developer and Full-Stack Developer, I work with PHP, REST APIs, MySQL, JSON, and mobile-connected business systems. My approach is to create a reliable integration layer that allows your app to push new records into Tally while continuously pulling updates back into the mobile platform without manual intervention. Depending on your setup, I can implement the most suitable approach using TallyPrime XML, ODBC connectivity, a REST layer, or a hybrid solution. The focus will be on accurate synchronization, secure data transfer, error handling, and a maintainable codebase so your team can manage and extend the integration confidently. Relevant experience: • MAB POS • Power Express I prioritize reliable communication and well-documented solutions, especially for integrations where business data accuracy is critical. One question: is Tally hosted on a local machine, server, or cloud environment, and which Tally version are you currently using? I’d be happy to review your setup and discuss the most stable integration architecture.
