Billa

Inspiration

People shouldn’t have to send five different payment details to get paid. Whether you're a freelancer, small business, or creator, collecting money across banks, crypto, and fintech apps is a mess. We wanted a simple way to unify all payment methods into one clean, shareable profile — something like Linktree, but for payments.

What it does

Billa is a Universal Payment Profile. With one link, users can collect payments through:

Traditional bank accounts
Crypto wallet addresses (manual input)
Digital wallets like PayPal, Cash App, etc. A clean, simple interface for anyone to say: "Here’s how to pay me — pick what works for you."

Each user gets a public profile like billa.xyz/username, and can customize it with their payment methods.

How we built it

Bolt for working MVP Supabase for authentication (Google sign-in) and user/payment data Netlify for deployment TailwindCSS for styling

Challenges we ran into

Mapping a simple UX that worked across very different payment methods
Avoiding feature bloat — we postponed transaction history, wallet connect, and fiat verification
Ensuring mobile-first experience worked as well as desktop

Accomplishments that we're proud of

Built a working MVP: login, create profile, add payment methods, and share your link
Got testers to say: “This is what I’ve needed for a long time.”
No fluff. Just a tool that helps people get paid.

What we learned

Simplicity trumps features. The biggest win was reducing steps
Most users don't need automation at first — they just want to share how to get paid
It’s possible to build something globally useful with a lean stack in days
