Pro-Tip: Professional Invoice Formatting
For a professional appearance and better tax organization, avoid using simple numbers like "1, 2, or 3." Instead, use a Prefix-Year-Sequence format to make your billing system more robust.
- Best Practice Example:
INV-2026-001 - INV: Short for "Invoice" (This identifies the document type).
- 2026: The current financial year (Essential for record-keeping and audits).
- 001: The unique serial number that increments for every new client or bill.
