GST Invoice App: Create GST Bills on Your Phone

Updated · 3 min read · PocketInvoice Team

With PocketInvoice you can make GST invoices on your phone in seconds: add your GSTIN to your business profile, save your tax rates once (GST, CGST, SGST, IGST, or VAT), and they appear on every bill. Works in ₹, fully offline, and shares straight to WhatsApp.

What a GST invoice needs

A standard GST invoice generally includes:

  • Your business name, address, and GSTIN
  • A unique invoice number and date
  • The customer's name and details
  • Description of goods or services with quantities and rates
  • The tax rate applied and the tax amount
  • Total amount payable

Requirements vary by registration type and turnover — when in doubt, confirm the exact format with your CA. PocketInvoice covers the fields above out of the box.

Set up GST in PocketInvoice once

  1. Add your GSTIN: open your business profile and enter your GSTIN in the tax number field — it then appears on every invoice you create.
  2. Save your tax rates: create the named rates you actually use (for example GST 5%, GST 12%, GST 18%, or CGST and SGST as separate rates) — one time, reusable on every bill.
  3. Set ₹ and date format: pick Indian Rupee and your preferred date format in settings.

Make and send a GST bill

  1. Create a new invoice and add the customer.
  2. Add items — apply the right saved tax rate per item; totals calculate automatically.
  3. Pick a template (structured layouts show tax columns clearly).
  4. Share the PDF straight to WhatsApp, email, or print it.

Works offline — made for shops and field work

PocketInvoice needs no internet and no account: bill customers during network outages, at exhibition stalls, or on service calls. Everything stays on your phone like a digital bill book. The app interface is available in Hindi and 21 other languages, and your invoices are generated in clean, professional English.

Track every bill like a digital bill book

Every GST bill you create is tracked automatically: paid, unpaid, partially paid, and overdue, with totals at the top of your list. Record part payments as customers pay, set due dates so the app reminds you to follow up, and pull sales reports by customer or item whenever you need them for bookkeeping.
