There's no single "best" way — there's a best way for your volume. Here's an honest breakdown of what each method actually costs you in time.
Most guides just tell you "use software." But if you're only handling 5 invoices a month, a full tool might be overkill. If you're handling 500, manual entry will eat your week. The right method depends entirely on your volume and how often you need this data in Excel — so we've broken it down by actual use case.
Open the invoice PDF, read each field, type it into a spreadsheet. Works fine for a handful of invoices a month. Becomes a real time cost past 20-30 invoices, and manual entry is where most GSTIN/HSN typos creep in.
Pre-built templates with GST fields (GSTIN, HSN/SAC, CGST/SGST/IGST) already laid out with formulas for tax calculation. Good for creating new invoices from scratch — but they don't extract data from existing invoice PDFs, so they solve a different problem than "I have 40 vendor PDFs to convert."
Windows-based tools built for CA workflows — handling PDF-to-Excel conversion, GST invoicing, and direct Tally XML export, all processed locally without uploading data to the cloud. A strong fit if your firm has a strict no-cloud-upload policy or needs deep Tally integration, though it does mean installing and maintaining desktop software.
Upload the PDF/JPG/PNG, AI reads and extracts GSTIN, CGST/SGST/IGST, HSN code, invoice number, date, and totals automatically, and you download a ready Excel/CSV file — no installation, works from any device. Best fit when you need quick turnaround across many invoices from different vendors and don't want new software on office machines.
