GST is a destination based tax consumption of goods and services which is levied at all stages of movement, right from manufacturer, up to final consumption wherein credit of taxes already paid at supply chain is available for set off.


ERP players such as SAP, ORACLE, MS DYNAMICS etc. have made their product incorporated with GST compliance requirements and have proved their importance in day to day transactions. New players such as ZOHO applications have also emerged with its online application and GSTR filing facility. This change in ECO-Business Environment has also boosted the demand of ERPs.

Now with rules and rates kept same after 26th GST Annual General Meet held on 10th March 2018, GST will make businesses to revisit structure configuration in ERP for procurement, sales and financial modules.

Tax Invoice

As per the new GST regime, the sales invoices are the major source to decide the revenue and the turnover. Also, under GST, there is no provision of deleting any tax invoice which are taken care by ERP.


Reference Number for Tax Invoice and for Advance Receipts

  1. ERP has the facility to track and cross verify the authenticity of the documents and transactions for which there is predefined fields to record the reference number in generating the tax invoices.
  2. As advance receipts are the major transaction in GST enabled business processes, ERP applications are efficient in tracking invoices against the advance payments and their receipts. The receipts are thus required to be uploaded at GSTN on the same date of receipt of advance payments and the same as to be given link to the generation of invoices to reconcile the amounts/ transactions.


Working with Tax Credit

  1. Input Tax Credit – Another benefit on ERP is that the input tax credit can be availed on provisional basis on the payment of taxes by the vendors. The application has their own track on generating the input credits.
