Invoice Kilat FAQ
Do I need special skills?
No. Just fill in the sheet like usual and click to create the PDF.
Can I use my own logo and signature?
Yes. Upload them as PNG files (a transparent background looks best).
Can I invoice international clients?
Yes. Choose English and USD, and the amount in words switches too.
Can I use it for more than one business?
One purchase covers one business. Need it for several? Message us first.
Is there a limit on invoices?
We don't set one. Normal daily use is fine. The only limit is Google's standard daily quota for free accounts.
Can I remove the "Made with KilatScript" line?
It stays in the Basic version. The upcoming Pro version will let you remove it.
What if it's not right for me?
We'll help you set it up until it works. If it's still not right, you get your money back within 7 days.
