GST or non-GST – your choice

Turn GST billing on or off to match your shop. With GST on, PhoneStock calculates CGST and SGST automatically. With GST off, you get a clean non-GST bill.

Your brand on every invoice

  • Shop name, logo and address
  • Custom invoice number prefix
  • Warranty and terms of sale
  • Optional bank account and UPI details
  • Exact phone sold, linked by IMEI

Share on WhatsApp or print

Send the PDF invoice to the buyer on WhatsApp or email, or print it on a Bluetooth or Wi-Fi printer. The buyer gets a proper bill, and your shop looks professional.

Stock, ledger and profit update with every bill

Because the sale is made from your stock in hand, the phone leaves your stock automatically. Amount paid and balance due go to the customer ledger, and the profit on that phone is calculated from its purchase price.

Simple pricing with a free trial

Download PhoneStock from Google Play, sign in with your mobile number and OTP, and add your shop details. Every feature is open for 7 days, and no card is needed to start.

When you are ready, plans start at ₹1,999 per year, paid securely inside the app through Razorpay. If your plan ever ends, your records stay safe and readable.
