Frequently Asked Questions
Yes. There are no fees, no sign-up, and no watermarks. Your invoice data never leaves your browser — everything runs locally using PDF-lib.
When the seller and buyer are in the same state (intra-state), GST is split equally into CGST (Central) and SGST (State). When they are in different states (inter-state), only IGST (Integrated GST) applies. Doclair detects this automatically based on your seller state and place of supply.
GSTIN (Goods and Services Tax Identification Number) is a 15-character alphanumeric code assigned to every GST-registered business in India. The format is: 2-digit state code + 10-character PAN + entity type + Z + check digit. Doclair validates the format instantly as you type.
HSN (Harmonised System of Nomenclature) is an internationally accepted 4-8 digit code that classifies goods. In India, HSN codes determine the applicable GST rate for each product or service. SAC (Service Accounting Code) is used for services.
Yes. Select "Bill of Supply" from the Invoice Type dropdown. Bill of Supply is issued by composition dealers or when supplying exempt goods/services where no GST is collected.
The PDF generated contains all mandatory fields required under GST rules (GSTIN, HSN, tax breakup, place of supply, etc.). However, you should consult a CA to confirm compliance for your specific business situation.
