I built a simple invoicing app because every tool felt like too much or too little

Hey Indie Hackers 👋

I wanted to share something I've been building: Invoex, a simple invoicing app for freelancers and small businesses.

Why I built it

For a while now I've been billing clients, and invoicing was always a small, recurring headache. The tools out there felt like two bad options: heavy accounting suites like QuickBooks and Xero that were overkill and overpriced for what I needed, or free tools that looked unprofessional and couldn't even handle tax properly.

I just wanted to send a clean, professional invoice and get paid — without learning an accounting system or paying enterprise prices. Nothing quite fit, so I decided to build it myself.

What it does

Invoex keeps it focused on the core job:

• Create invoices, quotes, proformas, and credit notes in minutes

• Get paid with Stripe & PayPal built in

• Manage clients, a product/service catalog, and expenses in one place

• VAT-inclusive and multi-currency-ready billing (I made a point of getting tax right, since that's where a lot of "simple" tools fall apart)

• Dashboards and reports for cash-flow visibility

• Security done properly — encryption and two-factor auth

How I built it

Solo, from scratch, on a modern stack (Next.js, TypeScript, Prisma/PostgreSQL, Stripe/PayPal). I wanted to prove you can deliver premium polish at an accessible price without a big team. It's been a lot of iterative building — the coupon/campaign system, security hardening, and getting the tax handling right were the trickiest parts.

Where I'm at

The product is live and ready. Now I'm focused on the part I find hardest as a builder: getting it in front of the people who need it. That's the honest challenge — I can build, but distribution is the mountain ahead.

A little something for this community 🙌

Since Indie Hackers is exactly the crowd I built this for, here's a genuine thank-you: 50% off with code INDIEHACKERS50, valid on the Premium Business and Unlimited Lifetime Pro plans. No catch — just my way of saying thanks for taking a look.

I'd love your input:

• For those of you who freelance or run small businesses — what do you actually want from an invoicing tool? What makes you switch (or stay)?

• Any advice on distribution for a focused B2B SaaS like this?

Happy to answer anything about the build, the stack, or the decisions along the way. Thanks for reading 🙏
