Built QkInvoice – a simple invoicing tool for freelancers. Looking for feedback

I’ve been freelancing and building tools for a while, and found myself frustrated with how overcomplicated invoicing tools can be — especially if you only need to send a few invoices a month.

So I built QkInvoice for myself:

• Create invoices in seconds

• Track status (draft, sent, paid, overdue)

• Export clean PDFs

• Manage basic client info

It’s super simple, no bloat, no learning curve. Think of it as the “notes app” of invoicing tools.

I’d love to get honest feedback from other indie hackers, freelancers, consultants - especially if you’re building solo or working with clients.

First users can use 50% off the lifetime/subscription plan (LUOTTEGR).
