Tip
Unreliable internet? Prepare Offline billing while connected, then save invoice drafts and cash sales on the device. They sync when you reconnect with the app open.
Moving from another billing app?
The owner can download records and import supported CSVs from Settings → Data & backup. Start with customers and products, then bring item-level invoices and dated payments. Keep your original app's backup; a native vendor backup is not a CSV.
Who it's for
- Shops, retailers & traders who bill walk-in customers all day and want stock, purchases and GST in one place.
- Freelancers & consultants who bill clients, want to look professional and need to get paid on time.
- Agencies & service businesses that work in milestones and need proof of delivery before payment.
- Small & medium businesses (MSMEs) that need GST-compliant invoices and a simple way to track dues.
Tip
InvoiceKaro runs in your browser, with nothing to install. Open invoicekaro.com/app on a computer and you get a full-height menu on the left; on a phone you get tabs along the bottom. Switch between English and Hindi with EN / हिं at the top of the screen.
How it works, in short
- 1Create your account with a one-time code on WhatsApp or email (no password and no card), then add your business details and your UPI ID or bank account.
- 2Add a customer and create a GST invoice. InvoiceKaro gives it the next invoice number, works out the tax and builds the PDF.
- 3Send it by email or SMS with a link to view and pay. The current WhatsApp option sends an alert without the pay link; to share it yourself, use the PDF and Mark as sent, then Copy pay link.
- 4Your customer pays straight into your UPI or bank account. You mark the invoice paid and the dashboard updates.
Selling at a counter? Quick Bill does all of this in one step for walk-in sales: tap the items, take the money, print the receipt.
