You no longer need a desktop and accounting software to raise a GST invoice. With a billing app like GSTify you can create a fully GST-compliant invoice on your Android phone in under a minute — and share the PDF on WhatsApp before the customer leaves the counter.
What a GST invoice must include
Under GST rules, a valid tax invoice should carry a few mandatory fields. Getting these right is what makes the document compliant:
- Your business name, address and GSTIN
- A unique, sequential invoice number and the invoice date
- The customer’s name, address and GSTIN (for B2B)
- HSN/SAC code for each item or service
- Taxable value, the GST rate, and the CGST/SGST or IGST split
- The total invoice value in figures (and ideally in words)
Creating one on your phone with GSTify
The flow is built to be fast — no menus to hunt through:
- Open GSTify and tap “New” → Tax Invoice
- Pick a saved customer (or add a new one with their GSTIN)
- Add products from your catalog — HSN, rate and unit auto-fill
- GSTify calculates per-line GST and decides CGST/SGST vs IGST by state
- Tap Generate to get a clean PDF, then share it instantly
Tips for clean, professional invoices
Keep your invoice numbers sequential within each financial year, save your most-sold products to the catalog so billing is one tap, and connect Google Drive backup so a lost phone never means lost records. Choose a PDF template that matches your brand — a consistent look builds trust with customers.
