You finished the work.
Now you just need to get paid.
That shouldn't require learning QuickBooks.

How it works

Four taps. One invoice.

Set up once, then every invoice takes less than a minute. Returning clients? Fifteen seconds.

1
Who's it for?
Type your client's name and email. Returning clients autocomplete instantly.
2
What did you do?
Describe the work in plain English. No line-item tables, no project codes.
3
How much?
Enter the amount. Invoice date and due date are set automatically.
4
Send it.
Email a beautiful PDF with your bank details and payment link. Done.
Built for freelancers

Everything you need.
Nothing you don't.

📱
Native iOS
Not a web wrapper. Built with SwiftUI for instant launch, smooth animations, and works offline.
📄
Beautiful PDFs
Clean, professional invoices generated on your phone. Your logo, your details, your brand.
⚡
60-second invoices
Four fields, one tap to send. Returning clients autocomplete. It's genuinely that fast.
🏦
Bank details included
Your payment info is on every invoice. Sort code, IBAN, Wise link — whatever your clients need.
🔒
Your data, your phone
Everything lives on your device. No account to create, no data on our servers.
✨
Instant branding
Upload your logo or pick a generated monogram. Every invoice looks like you hired a designer (even if you might be one).

Chasr doesn't do accounting.
Or expense tracking. Or time tracking.
Or proposals. Or payroll.

It does one thing — invoicing — and it does it better and faster than anything else on your phone.
