Frequently Asked Questions

Clicking "WhatsApp" or "Email" opens an interactive sharing dialog. You can choose to send directly to your Billed Client (pre-filled from form), your Accountant / CA, your Own Number/Email for records, or type any Custom Phone Number / Email with international country codes.

You can either upload a scanned transparent image of your signature (PNG/JPG) or draw your signature directly on screen using our interactive Digital Draw Pad. The signature is embedded cleanly into the "Authorized Signatory" box of your invoice.

Our smart engine compares the Supplier State and Place of Supply (Buyer State). If both states are the same (Intra-State), GST is automatically split 50/50 into CGST + SGST. If the states differ (Inter-State), the full tax is categorized as IGST. A comprehensive HSN/SAC tax breakup table is generated automatically.
