How to Create an A4 Invoice
Create a polished A4 invoice by choosing an industry template, entering supplier and client details, adding line items, and exporting the finished invoice as a print-ready PDF.
- Pick the industry template that matches your work, such as Freelance, Legal, Events, Logistics, Photography, or Interior Design.
- Enter invoice number, dates, business details, client details, and GST or international tax information.
- Add line items with descriptions, quantities or hours, rates, and category-specific fields like SKU, matter reference, route, package, or project phase.
- Review the live A4 preview and save a local draft if you want to continue later.
- Use Download PDF to print or save the invoice at A4 size.
Invoice Total Formula
Line total = Quantity or Hours x Rate. Subtotal = sum of all line totals. In GST mode, SGST and CGST are calculated from the subtotal using the selected percentages. Grand Total = Subtotal + SGST + CGST.
