Official GST invoice books and receipt pads require crisp carbonless duplicate or triplicate copy transfer without messy carbon paper inserts.
Duplicate vs. Triplicate NCR Formats
- Duplicate Books (1+1 - 50 Sets): White top sheet for customer, pink/yellow bottom sheet for accounting records.
- Triplicate Books (1+2 - 50 Sets): White top sheet for customer, pink middle sheet for transport/delivery, yellow bottom sheet for office files.
- Perforated & Sequentially Numbered: Clean tear-off perforation lines and red ink sequential numbering (e.g. 001 to 500).
GST Compliance Note: Official invoice books must prominently display your GSTIN number, registered business address, and legal terms.
