What is a GST Purchase Invoice?
Understanding purchase invoices and their importance in GST accounting
A Purchase Invoice (also called a bill or purchase voucher) is a document you receive from suppliers when buying goods or services. In GST accounting, recording purchase invoices is critical for maximizing Input Tax Credit (ITC), tracking expenses, monitoring cash flow, and ensuring GST compliance.
One of the most important considerations in the GST regime is obtaining maximum Input Tax Credit. By recording purchases in your accounting system, you can track ITC, calculate profit or loss, manage supplier payments, and monitor accounts payable. Every purchase invoice from suppliers contains key information: invoice number, date, quantity, description, taxable amount, and tax details.

Detailed guide to create and save purchase invoices
- Select Supplier: Choose from supplier master or enter new supplier name. System supports both registered and unregistered suppliers.
- Set Place of Supply: System auto-sets based on supplier's state. Manually change if delivery location differs.

- Add Supplier GSTIN: Enter or confirm 15-digit GSTIN. Auto-populated if supplier already in master.
- Enter E-com GSTIN (if applicable): For marketplace purchases, add e-commerce platform's GSTIN.
- Specify TDS (if applicable): Mark if TDS was deducted and mention the applicable section (194C, 194I, etc.).
