Tally.ERP 9 to Tally.ERP 9 integration is done through synchronisation. All the branches can periodically synchronise their data with the head office. Data Synchronisation refers to a process where data is replicated between two or more locations. It enables the branch offices to send data to the head office and vice versa, over a network with a dynamic IP address or static IP address. Data Synchronisation flows both ways, i.e., data flows from the Client to the Server and vice-versa.


If the masters and transactions is available in Tally.ERP 9 compatibly XML format, they can be directly imported in Tally.ERP 9.


Tally.ERP 9 allows the export of reports in four standard formats, viz. ASCII (Comma Delimited), Excel, HTML, and XML.


Tally.ERP 9 communicates with External Application using these interfaces:

  • XML Interface(Get/Post)

Using this interface Tally.ERP 9 can behave as a Server handing XML Requests from external Applications. Tally as a Client can also send an XML request to a Web Service

  • ODBC Interface(Read Only)

External Applications can retrieve data from the Tally.ERP 9 database by making an ODBC/SQL call. In the same way Tally.ERP 9 can retrieve data from External Data Source using an ODBC/SQL call.

  • DLL

The DLLs developed using other applications can be used to perform operations that are not available in the product. These external DLLs can be called from Tally.ERP 9 using the TDL language.

With these capabilities, you get to use Tally.ERP 9 as a single-window application across all software products in your enterprise.
