Frequently asked questions

What is it? Do I need to download it from an app store?

No. Invoice Kilat is a web app you open from a link. You only need a free Google account. Your data is stored in Google Sheets in your own Drive.

What does "pay once" mean?

You buy it outright. One payment, no subscription, and no monthly fee.

Where is my data stored? Is it safe?

All your data stays in your own Google Drive. We can't see it and we don't store it.

How do I install it?

Click the "Make a copy" link we send you. Then open the ⚡ KilatScript > 🚀 Cara Pasang Aplikasi menu and follow the steps. Install once from a laptop or Chrome in desktop mode, about 1 minute. You'll then get your own app link.

Does it work on my phone?

We're currently testing it on Android and iPhone, and we'll share the results once testing is done.

Why does Google ask for permission during install?

That's normal. The app runs in your own account, so Google asks once before it can save your data and create PDFs in your Drive.

How do I pay?

Through Mayar. Right after payment, the copy link and install guide are sent to your email.

What if I'm not tech-savvy?

No worries. Our 7-day guarantee covers you: we'll help you set it up on WhatsApp until it works. If it still won't work, you get a full refund.

Is there any KilatScript branding on the PDF?

Yes, a small "Made with KilatScript" line at the bottom of the PDF.

Is this an official Google product?

No. KilatScript is an independent product that uses Google Sheets and Google Drive to store your data.
