Gautam Jain, a cycle parts maker in Ludhiana’s Daba Road, has for years managed the daily accounts of his company. Every sale under the current system is done through a challan and invoices are made twice or thrice a month. His office attendant is able to write the details by hand in a challan whenever Jain is away. From July 1, all sales need to have a computerised bill with details such as the sellers’ and buyers’ goods and services tax network (GSTN) number and his attendant is not computer-literate. But Jain has found the solution in a new printer.
