My Micro SaaS Story: From EU Paperwork Hell to CSV2Invoice.com

An Email That Started It All…

I got an email from my EU accountant one gray morning. She needed sales invoices for every transaction my company made. My stomach sank—I had hundreds of sales and no easy way to make those invoices.

I use ThriveCart to handle payments—it’s smooth and simple. But there’s no button to download invoices in bulk. I wasn’t about to type them one by one—that’s a nightmare.

I replied to my accountant, “I’ll figure it out,” but I had no clue how.

Then it hit me: what if I built a tool to turn a CSV file into invoices?

That’s when CSV2Invoice.com was born in my head.

Building It Fast (With Claude and Cursor)

I’m not a coding pro, but I had Claude 3.5 Sonnet and Cursor ready to help. Claude is like a brainy bot that writes code when I ask. Cursor turns my wild ideas into a real app.

It took me three days—coffee in one hand, laptop in the other. I wasn’t sure it’d work, but I kept going. Each step felt like stacking blocks to build a little tower.

I’d seen ConvertKit let you upload a CSV to add subscribers. You match columns—like “name” or “email”—to their system. I thought, “I’ll copy that for invoices!”—and it clicked.

How the App Took Shape

The Upload Page Was First

I made a page where you drag a CSV file—like dropping a grocery list online.

A box pops up with headers: “first_name,” “last_name,” “address,” etc. You pick where they go on an invoice, like connecting dots.

Company Info Made It Real

Invoices need your business name and address—EU rules, right? So I added a page to type that in. It’s like giving your invoices a home address.

Previews and Downloads Sealed the Deal

After mapping, you see a preview—like checking a photo before printing it. Click “Generate Invoices,” and a zip file with all your invoices pops out.

It’s fast and feels like magic.

I tested a CSV with 2000 rows—a monster list of sales. The app crunched it in seconds, handing me perfect invoices. I grinned like a kid with a new toy.

Once you download, the app deletes everything—like it was never there. No leftover mess to worry about. My accountant got her invoices, and I got peace.

Could This Help Others Too?

One day, mid-shampoo, I froze. If I needed this, other EU entrepreneurs might too.

Why not sell CSV2Invoice and save them from the same mess?

I didn’t want to build logins or figure out Stripe—too hard, too dull. Databases? Nope. Payment code? No way. I just wanted my tool to shine, not get bogged down.

Beag.io Became My Shortcut

Then I turned to Beag.io—a tool my friend and I created. It adds logins and payments with one line of code. I thought, “This is it—my easy way out!”

I jumped into Beag.io and added CSV2Invoice’s details—like its name and a little logo. Linked my Stripe account with a couple of clicks. It was like signing up for a game—fast and fun.

Beag.io gave me a short script tag—like a secret key. I pasted it into the pages I wanted to lock—like the upload and download spots.

Boom—my app was safe and ready to sell.

Now, only signed-in users can use CSV2Invoice. Beag.io stands guard like a quiet watchdog. I didn’t have to build anything—it just happened.

Getting Ready to Sell

A Sales Page Came Together

I built a sales page for CSV2Invoice.com on a quiet Sunday—just the basics. It says, “Bulk Invoices From CSV.” I took the Stripe link from Beag.io and dropped it in a pricing table—€10 a month, done.

The Phishing Scare

Some early Beag testers said, “Hey, the login is on Beag.io’s site, not yours—it looks weird!” They had a point—different domains can feel off. I needed to fix that fast.

My Own Login Page

Beag.io offers a self-login option—you can make your own login page.

I grabbed their guide, fed it to Cursor, and out came a custom login for CSV2Invoice, hooked to Beag.io’s system.

The Finish Line Felt Sweet

Now I’ve got a sales page, a custom login, and payment links—all polished up. EU entrepreneurs can buy it, use it, and ditch their invoice woes. I felt like I’d climbed a small hill—and won.

The app’s live, payments are set, but it’s a secret for now. I’ll hit Product Hunt, Reddit, maybe some forums—share my story loud. That’s next—I’ll tell you how it goes.

What I Learned Along the Way

Problems Can Be Gold

My accountant’s email bugged me, but it led to CSV2Invoice. Annoying stuff can turn into cool ideas. What’s bugging you today?

Tools Make It Easy

Claude, Cursor, Beag.io—they’re like buddies who do the hard parts. You don’t need to be a tech star—just grab the right helpers. What tools do you use?

Start Tiny, Grow Quick

I made this for me, then sold it with Beag.io in days—not years. Don’t wait for a perfect app—just build it and share it. What’s your next small step?

Why This Felt Like a Win

From Stress to Smiles

A few days of work, some Beag.io magic, and I turned a chore into cash. It’s crazy how a little idea can flip things around. I’m still buzzing about it.

You Can Build Stuff Too
