E-Invoicing in ERPNext v13 - Setup Queries & Errors

ERPNext
3

Hello guys,

I have purchased an API subscription from Adaequare.

I have created an App in the Adaequare portal and got the Client ID & Client Secret.

In the E-Invoice Settings, I have made the following below setup:

  1. Sandbox: Enabled
  2. Credentials Table:
  • Company: Selected from Company master
  • GSTIN: Provided by Adaquare for testing purpose
  • Username: Provided by Adaquare for testing purpose
  • Password: Provided by Adaquare for testing purpose
  1. Advanced Settings:
  • Client ID: From the app created in Adaquare portal
  • Client Secret: From the app created in Adaquare portal

After this I tried to generate IRN , it is giving me the below error:

E-invoice credentials error

From this link: [E-Invoicing][India][Guide] Setup Adequare GSP’s E-Invoicing Services in ERPNext it says - The sandbox GSTIN used in the E-Invoice Settings (eg. 01AMBPXXXXXXXXX) needs to be saved into the company address GSTIN field as well. But if we try to edit the GSTIN in the company master address, it gives the invalid GST error.

Can anyone please help me to solve this issue. Has anyone successfully used the Sandbox mode in ERPNext??

Thanks & Regards,
Sujay
