Question 1

What's the catch with free?

Accepted Answer

There isn't one on invoices — unlimited, forever, on every plan. Free PDFs carry one small line at the bottom saying "Made with BillKar". ₹199/month removes that line and adds payment reminders, recurring invoices and GSTR-1 export.

Question 2

Do I need a GST number to use BillKar?

Accepted Answer

No. Freelancers below the registration threshold use BillKar for plain invoices. Add your GSTIN whenever you register and the tax fields start appearing.

Question 3

Will it calculate CGST, SGST and IGST correctly?

Accepted Answer

Yes, and you can check before signing up. Place of supply decides it: the same state gives CGST + SGST, different states gives IGST. The live invoice on the homepage runs the same code the app does.

Question 4

How does my client pay the invoice?

Accepted Answer

You send a link. They open it in any browser, see the invoice, and tap Pay with UPI, which opens GPay, PhonePe or Paytm with the amount filled in. They do not need an account or an app.

Question 5

Do I have to install an app?

Accepted Answer

No. BillKar runs in the browser and can be added to your home screen, where it opens like an app. It works on any Android or iPhone.
