I'm Daniel. I built a simple and straightforward API: you POST a JSON payload with your invoice data, and it returns a secure, presigned URL to a generated PDF. The goal is to make invoicing a single, reliable API call so you can get back to your main product.
I also used this as a personal challenge to move away from my old LAMP stack background and build something new with Python/FastAPI, Next.js, and a serverless architecture on GCP and AWS.
For the HN community, I've set up a promo code: HEYHN100
If you sign up, you can redeem it in your dashboard for 100 free credits (on top of the 10 you get by default). The credits don't expire.
I'm here to answer any questions and would genuinely appreciate any feedback or technical critiques you have. Thanks for checking it out.
