The effect on small companies which process their accounting data on a monthly basis and the effect on big companies which process documents real-time would however be different.To see the possibilities with respect to small com-panies, let us assume that a company has 300 sales in-voices and 500 purchase invoices to process. Assuming a normal situation, a total of 800 documents would be keyed into the accounting systems of the company. Data relating to the 300 sales invoices would then be extracted from the accounting systems and GSTR-1 would be prepared based on that and filed. Also, GSTR-2A would be checked with the data in the ac-counting systems relating to the 500 purchase invoices, and finalized for submission as GSTR-2. Now, since in-voice-wise data of purchase invoices are made available to the company by the government, it may make sense to explore if keying in of the 500 purchase invoices can be avoided in future. The company can simply download all purchase data from the GSTN system of the govern-ment, verify that with the documents already received from the vendors for payment, and finalize GSTR-2 after making any rectifications required. Once that is done, the same data can be simply uploaded into the company's accounting system, which will completely avoid keying in the purchase data. If that can be achieved, it will mean a very significant saving in the time, efforts and cost re-quired in getting the purchase data into the system.As for big companies processing documents on re-al-time basis, I believe that the new GST scenario will result in a big boost to Electronic Data Interchange (EDI) processes, once the nationwide GST implemen-tation process settles down. A big company will have thousands of purchase invoices processed in its ERP sys-tem every month. And, when it gets its GSTR-2A for verification, it will find out the differences between its own data and the data as submitted by its vendors. The company will just have a few days to finalize their GSRT-2 and submit it, making changes as it deems fit. It can then take up the task of rectifying the situation, by con-tacting the vendors in connection with whom mistakes have been noted. There is a legal deadline by which the mismatches will have to be sorted out; otherwise, the company will have to add the tax amount in question to its output tax liability, and pay it to the govern-ment. Considering that the volume would be very high, with probably hundreds of vendors to be dealt with, the company may not be able to set right the mistakes within the legal deadline, resulting in an un-necessary tax payment, which can be really huge. To avoid this unnecessary payment, it makes sense to start the process of identifying the mismatches at the ear-liest possible opportunity. An EDI system would give the best chance of avoiding this issue, since it will bring out any mismatch at the earliest possible time frame, that is, even before the end of the month and even before GSTR-1 is filed by the vendors. Hence, I believe that EDI projects will get a big boost after GST implemen-tation is complete and trade and industry fully under-stand how things work under GST.
