I need a production-ready solution that plugs into Tally, reads and writes data seamlessly, and removes as much manual bookkeeping effort as possible for a handful of our chartered-accounting clients. The platform must cover three flows: Expense Invoices • Capture PDFs or scanned bills with OCR, push the key fields into structured tables, let a reviewer tweak anything the model is unsure about, then post the clean voucher straight to Tally. The workflow should also fetch existing ledgers from Tally so duplicate supplier names or GSTINs are never created. Sales Invoices • Our clients already raise invoices in their own software; I want those documents pushed into Tally through an API route, not by file upload. A lightweight mapping screen is fine, but the transfer itself must be fully automated and two-way (status updates back to the source app). GST Compliance • For every purchase entry the system should ping the GST portal (or consume the downloaded JSON) and confirm that the vendor bill appears in GSTR-2B. Any mismatch, rate error, or duplicate credit must be flagged on a dashboard and exported for follow-up. Core expectations – End-to-end Read/Write integration with Tally via XML, ODBC, or TDL gateway—whichever delivers the most stable throughput – Robust OCR layer (Tesseract, Google Vision, or similar) blended with a quick manual-edit screen so tricky images never break the process – Clean, searchable database and audit logs for every sync event – Role-based access and client segregation; each firm’s data must stay ring-fenced – Clear deployment guide so my in-house team can host it on our own server I’m comfortable with Python, Flask/FastAPI, and Postgres if that helps you frame the stack, but I’m open to other proven approaches provided the end result meets the three functional pillars above and can scale to roughly 20,000 vouchers a month without a rewrite. When you respond, please outline: 1. The libraries or SDKs you’d use for Tally connectivity 2. Your preferred OCR and GST API strategy 3. A timeline with key milestones from prototype to final roll-out A concise demo or screen capture of a similar integration you’ve completed will move your bid to the top. Would prefer developers who are based in Mumbai, and should have experience working with Tally XML import/export.

Hi there, We can help design a production-ready automation flow around Python, Postgres, and a stable Tally integration path, with OCR capture, reviewer correction, audit logging, and GST exception checks. Our approach would start with a short discovery phase to confirm the Tally connectivity method, source invoice API path, and the safest GST data strategy before building the core workflows. We would structure the work so your team can review early outputs, validate field mapping, and keep the solution deployable on your own server. We can also keep the build focused on scalable, client-segregated processing so it is practical for multi-client accounting use. If helpful, we can outline the libraries, integration approach, and rollout plan in a clear milestone sequence. Best Regards, 8veer

Hello, I understand this is a full automation pipeline around Tally where reliability of data sync, OCR accuracy, and GST validation are critical, and my approach would be: document ingestion → OCR layer (Tesseract/Google Vision + preprocessing via OpenCV) → structured extraction with validation → manual review UI → Tally integration (XML/ODBC/TDL gateway for read/write ledgers + voucher posting) → sales invoice API ingestion with bidirectional sync → GST validation (GSTR-2B JSON/API reconciliation, mismatch detection) → centralized Postgres DB with audit logs → role-based access and multi-client isolation → dashboard for errors and reporting; the system will be built using FastAPI for scalable APIs, with clean modular architecture to handle ~20k vouchers/month efficiently, and deployed via Docker with clear setup docs; I’ve worked on similar data pipelines, OCR + ML systems, and automation workflows and can share relevant work, so if you want a stable, production-ready solution that actually reduces manual accounting effort, let’s connect.

Hi, I've built production-grade document processing and accounting integration pipelines in Python, and this project maps directly to that work. For the expense invoice flow, I'd use a combination of Tesseract and a vision-capable model to extract key fields from PDFs and scans, feeding results into a structured review interface built with Flask. Low-confidence fields get flagged for human review before anything posts. Before creating any supplier or GSTIN entry, the system queries Tally's XML/ODBC interface to check existing ledgers, preventing duplicates at the source. For the sales invoice flow, I'd build a Tally-connected module that reads your clients' existing data via the Tally XML API, maps it to your GST filing requirements, and pushes structured voucher data back automatically. The GST portal integration would use Playwright-based browser automation to handle the submission flow where no direct API exists. The full stack would be Python + Flask backend, SQLite for job queuing and audit logs, and a lightweight reviewer dashboard. All three flows would be modular, so you can run them independently or as a unified pipeline. I've done similar work integrating scraped and OCR-extracted data into accounting and ERP systems. I know where these integrations break in production and how to make them robust. My bid is $29,250 over 21 days, which includes full deployment, documentation, and one month of post-launch support. Want to jump on a call this week to walk through your current Tally setup and data volumes?

Hi. Excel-to-database migration is usually won or lost in the cleanup step, not the import step. I’d first map the sheets properly, standardise fields, remove duplicates, and then load the cleaned data into a structure you can actually use going forward. I’m comfortable handling the Python/ETL side as well as the practical spreadsheet edge cases that usually show up halfway through. I can start now. What’s the destination system for the final import, a CRM, SQL database, or something custom?
