Built a No-Friction Invoicing Tool – Would Love Feedback 🙌

I kept hearing that most invoicing tools are too bloated and over-engineered for what should be a simple task: creating and sending an invoice. Let’s be honest—when it comes to invoicing, we all just want to get it over with, fast.

So I built a small MVP: a super lightweight invoice generator focused on speed and simplicity: https://happy-bill.vercel.app/

I’d love your thoughts, especially on these:

• What integrations (e.g. Notion, Trello, Asana, Gmail) would actually make invoicing faster for you?

• Would you prefer a sharable link to an invoice instead of sending a PDF?

• How useful would payable links (e.g. PayPal or Stripe) be for your workflow?

• Would you like it to be optimized for mobile?

My goal is simple: make invoicing suck less. 🙂
Would love your feedback!
