2. Add your PDFs — Drag and drop all the invoice PDFs you want to merge.
3. Arrange and review — Reorder the documents as needed. Preview pages to verify content.
4. Merge — Combine all PDFs into a single file with one click.
5. Download — Save the merged PDF for your records.

Why Organise GST Invoices as PDF?

• GST Return Filing — Keep invoices organised for GSTR-1 and GSTR-3B filing. A single PDF per month or quarter makes verification easier.
• Audit Preparation — Combine all invoices for a specific period into one file for easy sharing with auditors.
• Input Tax Credit (ITC) — Maintain organized records of purchase invoices to support your ITC claims.
• Digital Record Keeping — As per GST rules, invoices must be maintained for 6 years. Digital PDFs are easier to store and search.
• Sharing with CA — Send a single PDF to your chartered accountant instead of dozens of individual files.

Tips for Managing GST Invoice PDFs

• Name files clearly — Use a naming convention like GST-Invoices-Apr2024.pdf for easy identification.
• Photograph invoices clearly — When photographing paper invoices, ensure the GSTIN, invoice number, date, and amounts are clearly readable.
• Organise by month — Create one merged PDF per month for easier filing.
• Keep originals — Always keep the original invoice files alongside your merged PDFs.
• Check readability — After converting, open the PDF to verify all text is legible.
