Leading Tally Solution Providers

Tally Developer

Tally.Developer 9 (TD9)is a comprehensive development suite designed to enable TDL programmers to develop, and deploy solutions for Tally.ERP 9

Tally Definition Language (TDL)

At the heart of Tally, TDL forms the key link between the application and the platform layer. TDL provides the user with flexibility and power to extend the default capabilities of Tally and integrate with external applications. TDL provides capabilities for rapid development, rendering, data management and integration.

The Tally Definition Language (TDL) along with the development suite Tally.Developer 9(TD 9) provides the strong technology backbone for developing solutions on Tally platform


Capabilities of TD9

Solution-ability & customizability

TDL is a powerful tool in the hands of the programmer which enables customizability and solutioning capability in the product. TDL is platform independent, i.e., the TDL programs remain the same irrespective of which operating system/ network environment one uses. TDL automatically takes care of all developmental features of a solution, be it entries, reports, printing, data export in various formats with a single unified program. There is no requirement of resources with varied technical expertise to build these diverse functionalities unlike other technologies which may require a database programmer, an application programmer, a systems programmer, etc

Multiple output capability

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.

Data management capability

Data is stored and retrieved as objects in Tally. There are many internal objects predefined by the platform; using TDL, it is possible to create and manipulate this information with ease. If an additional field is required by the user to store information as a part of the predefined object, that capability is also provided, i.e. by using TDL, the user can create a new field and store value into the same, which can be persisted in Tally database.


Tally has been designed to provide extensive integration capability which enables the developer community to exploit and deliver cross platform solutions thereby allowing seamless interoperability among multiple applications with the Power of Simplicity
