Common Invoice Mistakes to Avoid

Entering an incorrect invoice number or invoice date.
Using the wrong quantity, rate, discount, or GST rate.

Using an incorrect HSN or SAC code where applicable.
Confusing GST-inclusive pricing with prices before GST.
Failing to review the invoice preview before downloading the PDF.
