Are these bills legally valid?

The formats follow the structure of the documents you normally receive, including GST fields where relevant. They are intended for personal records, reimbursement claims and internal bookkeeping. You are responsible for the accuracy of the details you enter and for confirming that a format meets your employer's, GST or tax requirements.

Is my data uploaded anywhere?

Bill Generator preview and PDF export are designed to process in your browser. Inputs and images you add for the generate/download path are not uploaded to Nelstack servers as part of that workflow. See the Privacy page for contact forms and analytics.

How is GST calculated?

Enter each line item with its quantity, rate and GST slab. For transactions inside the same state the tax splits into CGST and SGST at half the slab each. Mark the invoice as interstate and it switches to a single IGST line at the full slab. Totals are rounded to two decimals and also written out in words.

Can I add my own logo and signature?

Yes. Most formats accept a logo and a signature image. They are designed to be processed in your browser, embedded in the preview, and rendered into the downloaded PDF.

What paper sizes can I export?

Everything exports as a clean A4 PDF. Formats that mimic point-of-sale slips — fuel, recharge, restaurant and thermal invoices — also export at 80mm thermal width for receipt printers.

Does it cost anything?

No. Every format is free, unlimited and watermark-free. There is no signup and no account required.
