FAQ

Invoice & Billing Tools FAQ

Find answers to common questions about our billing document generators.

The tools are free to use and do not require an account. Downloaded PDFs carry no watermarks.
Yes — add your business name, logo, GSTIN, client details, items, pricing, tax rates, payment terms and notes. Each document reflects your business identity rather than a generic template.
Most generators — invoice, quotation, receipt, challan, salary slip — process your inputs in your browser. The Contract & Agreement, Partnership Deed and Joint Venture generators prepare drafts on our servers using the details you submit; those inputs are used only to create your document. See our Privacy Policy for site-level data details.
Yes — enter your GSTIN, client GSTIN and tax rate; the tool calculates CGST + SGST for intra-state supplies or IGST for inter-state supplies, and supports HSN/SAC codes and multiple line items with different rates.
A Proforma Invoice is a preliminary document sent before an order is confirmed — it shows expected price and terms but is not a payment demand. A regular Invoice is issued after delivery and is the official payment request. Use the Proforma Invoice Generator for pre-order confirmations and the Invoice Generator for final billing.
A Credit Note reduces the amount owed — for returns, overcharging or post-billing discounts. A Debit Note increases the amount owed — for undercharging or additional charges. Both are used for GST adjustments after an invoice is issued.
A Delivery Challan is used when goods move without a tax invoice — for job work, branch transfers, goods sent on approval, or similar cases. It records supplier, consignee, goods, quantity and vehicle details.
Yes — every generator produces a print-ready PDF download without watermarks, ready to email, print or share.
