What we sell and how it is delivered
Heartinz Technologies Private Limited sells software subscriptions (such as NegoBill), free mobile apps, and custom software services. None of these is a physical product, so nothing is shipped and there is no shipping charge.
- Software subscriptions are delivered online, instantly. The moment a payment is confirmed through Razorpay, the plan is switched on in the customer’s account on the product’s website (for NegoBill, app.negobill.com) and every feature of it is open. The GST invoice is available in the product under Billing & Plans and is also emailed on request. Delivery time: immediate; in the rare case a plan is not active within a few minutes of a successful payment, email support@heartinz.com with the order number and it is put right the same working day.
- Mobile apps (Charge Meter, Network Meter, NegoBill) are delivered through Google Play and the Apple App Store; installation and updates follow those stores’ delivery.
- Custom software services are delivered as agreed in the written quote: source code, builds, store listings or deployed systems, handed over on the dates in the quote.
Exchange
A software subscription cannot be exchanged for a physical item. A customer who bought the wrong plan can change plan at any time from Billing & Plans: moving up starts a fresh year on the bigger plan, moving down takes effect at once with the paid validity continuing. Refunds, where they apply, follow our Cancellation & Refund Policy.
Service area
Our software is sold to businesses in India and priced in Indian Rupees. It can be used from anywhere with an internet connection.
