TallyPrime Developer is a comprehensive development suite designed to enable TDL programmers to develop and deploy solutions for TallyPrime
At the heart of TallyPrime, TDL forms the key link between the application and the platform layer. TDL provides users with the flexibility and power to extend the default capabilities of TallyPrime and integrate with external applications. It offers capabilities for rapid development, rendering, data management, and integration.
The Tally Definition Language (TDL), along with the development suite TallyPrime Developer, provides a strong technology backbone for developing solutions on the Tally platform.
TDL can be used to generate output for multiple devices and in multiple formats. Whenever an output is generated, it can be displayed on the screen, printed, transferred to a file in a particular format, mailed or transferred to a webpage using HTTP protocol.

TallyPrime Developer simplifies a programmer’s life with powerful features like the search engine, syntax highlighting, column selection, and auto-completion. The editor enables you to handle multiple projects, navigate across definitions, collapse and expand definitions, and debug the code.
Tally Authentication Library for Mobile
The development kit Tally Authentication Library is available as part of TallyPrime Developer. This library provides user authentication with the help of Tally.NET Server, the gateway to interact with the TallyPrime application remotely.
Tally connector
Tally Connector empowers the programmer to send XML requests to Tally and get responses in XML format, enabling faster and seamless integration.
Licensing abilities
Control license usage and minimize revenue leakage with TallyPrime Developer. The TDL code can be configured to run on one or more Tally serial numbers while creating the TCP (Tally Compliant Product) file. You can also stamp the TCPs for a specific site.

As a practicing Chartered Accountant, I’ve been using **Tally Prime** for several clients’ accounting and GST compliance requirements over the past few years. Tally has proven to be one of the most dependable tools for managing day-to-day bookkeeping, preparing GST returns, and ensuring accuracy in compliance

With Tally Prime’s direct GSTR‑1 upload feature, our compliance time has shrunk dramatically. Before switching to Tally Prime’s GSTR-1 upload workflow, our team manually exported data, logged into the portal, uploaded files, checked for rejections, and handled correction loops—and it consumed half a day every month. What once took a half-day now takes only an hour. Highly recommend this to any business using Tally for GST filing.

TallyPrime now helps in filing various returns and reconciling all the GST returns filed with tally data, like GSTR3B, GSTR1, 2B v/s Input claimed, 2A v/s Input claimed, IMS direct upload, etc. with so much ease.

Another amazing feature “Upload GST Returns” in TallyPrime- Upload the GSTR-1 directly to the GST portal without login to the portal, which can then be previewed and filed using EVC or Digital Signature Certificate (DSC).
