Tally Customization using Tally Definition Language (TDL)
Make TallyPrime work exactly the way your business operates. From bespoke invoice printing with QR codes and custom approval workflows to third-party ERP integrations and industry-specific vertical solutions — built on 100% update-friendly TDL code.
What Makes TDL Powerful & Reliable?
Tally Definition Language is an action-driven, object-oriented language developed by Tally Solutions for rapid business customization without modifying core application source code.
Bespoke Invoice & Voucher Formats
Design customized tax invoices, e-Way bill formats, delivery challans, and thermal receipts with branded logos, barcodes, dynamic QR codes, and multi-currency displays.
User Defined Fields (UDF)
Add custom data fields to voucher screens and master records (e.g., Vehicle No., Dispatcher Name, Container ID, Warranty info) with complete data validation.
Security & Internal Controls
Enforce strict operational policies: restrict back-dated entries, block voucher alteration without admin password, hide cost prices from billing clerks, and mandate credit limit approvals.
Advanced MIS & Business Intelligence
Build specialized managerial dashboards, salesman commission reports, batch-expiry trackers, party-wise aging matrices, and multi-entity consolidated summaries.
Update-Friendly Codebase
TDL code runs on Tally's definition layer. Your custom reports and business logic remain completely stable and unaffected when upgrading to newer TallyPrime releases.
Two-Way API & External Integrations
Seamlessly connect TallyPrime with third-party CRMs, e-Commerce platforms (Shopify, Amazon, WooCommerce), WMS warehouse software, and payment gateways via XML/REST APIs.
