I'm a new startup of proprietorship firm (Registered Under Service Tax / GST / Turnover 15 Lacs) and want to know is Serial Numbering on Invoice will be compulsory? like INV0001, INV0002, etc.
Because till now I was use to send based on customer's UID such as:
Customer UID: 785881 Invoice No.: INV/785881/1, etc.
So what can do? Because I'll get business if I use INV0001, etc. because then customer will be able to see I don't make business.
Thanks for confirming we'll continue to use as following... Hope I was able to clarify that we'll be using invoice based on customer id and as you said it does not exceed 16 digit alphanumeric invoice no.
Customer UID: 785881 Invoice No.: INV/785881/1, etc.
Customer UID: 785882 Invoice No.: INV/785882/1, INV/785882/2, INV/785882/3, etc.
Customer UID: 785883 Invoice No.: INV/785883/1, INV/785883/2, etc.
