Free tools for the everyday work of an Indian business
These are small, single-job tools for the paperwork owners, accountants and sales staff do every week: a bill for a customer, a quotation, a challan for job work, a GST figure checked before a call, a QR for the counter, a reminder for a late payment. Each runs entirely in your browser and works on a phone as well as a computer. There is no sign-up, and nothing you type is sent to us — the documents and drafts stay on your device. If you print or save a PDF, that copy is yours to keep wherever you like.
How the tools are grouped
- Billing documents — invoice, quotation, proforma, purchase order, delivery challan, estimate, receipt, credit and debit notes, and work orders. All use the same document maker: you type straight onto the A4 page, GST is split from the two states, the amount is written in words in lakh and crore, and you can add your logo, signature and a UPI QR, then download a PDF.
- GST — add or remove GST at any rate with the CGST and SGST or IGST split.
- Collections — overdue interest, payment reminders in English, Hindi or Hinglish, and receivables ageing.
- Codes & scanning — QR codes (including UPI), Code 128 and EAN-13 barcodes, and scanners that read codes from an image or the camera.
- Branding — a simple logo maker for your bills and WhatsApp profile.
