I built a free no-signup billing toolkit for freelancers. Would love blunt feedback

I am preparing SunnyBill for a Product Hunt launch and wanted to share it here first for feedback.

SunnyBill is a free billing toolkit for freelancers, contractors, and small service businesses.

The problem I am trying to solve is simple: a lot of billing tools feel too heavy when all you need is to create a clean invoice, receipt, quote, or tax estimate quickly.

SunnyBill currently helps with:

• Invoices, quotes, proforma invoices, and receipts

• Clean PDF export

• Logo, signature, payment details, and tax fields

• 1099 and self-employment tax estimates

• GST/VAT style bills for India, UK, and EU use cases

• Time billing tools

• No signup and no watermark

I am not trying to build a full accounting app. The goal is to make small billing tasks faster when someone just wants to bill a client and move on.

I would really appreciate feedback on three things:

1. Does the homepage explain the product clearly?

2. Is the invoice flow simple enough for a first-time user?

3. What billing or tax tool would make this more useful for freelancers?

Blunt feedback is welcome. I would rather fix weak parts now than discover them after launch.
