Wrong EWAY bill issued

NPS WALIA (CEO) (38 Points)

25 December 2019  
we have two companies (different GST numbers, ) handled by one accountant. Names of companies are somewhat similar.
e.g.
ABC industry
ABC Ind Pvt. Ltd.
we undertake Jobwork services in both companies. material received from customers against RGP and customer E-WAY bill.

By mistake our accountant kept making EWAY bill from one company only irrespective of inward EWAY bill belonging to the other company.
