How do I setup BUSY to integrate with the government e-invoicing system?

To set up the E-invoice option in BUSY, follow the steps given below:
Step 1: Log in to the E-way bill site and click on the Registration option, then select the GSP
option. Define an OTP there and create a GSP user ID and password for Webtal Electrosoft
Private Limited and Pinnacle Finserv Advisors Private Limited.
Step 2: Now open the company in BUSY and go to the Administration menu.
Step 3: Click on the Feature and Option and then click on the GST/VAT tab. Enable the 
E-invoice option from there and define the Station and Pincode there.
Step 4: Define the GSP user ID and password in the GSP configuration window, then save 
the configuration.
Step 5: Go to the Voucher Series Configuration option under the Administration menu, then 
click on the Sale option followed by the Series and, at last, click on the Voucher 
Configuration option.
Step 6: Enable Input output details and Generate E-invoice after saving the voucher from
there. Now you can generate E-invoice of any party under B2B. One thing that you have 
to ensure now is that while saving the voucher, a transport window will appear. You have 
to set the E-invoice Reqd. option as "Y," then click on the Automatic option to correct 
possible errors from the "Check Possible Error" option, and then click on the Generate 
E-Invoice option. Through this, you can generate E-invoice automatically from BUSY.
