I just launched my first digital product — a tax tracker for freelancers. $0 revenue so far. Here's what I'm learning.

I've been building financial templates for freelancers and self-employed professionals.
Last week I launched my first paid product on Gumroad — a Self-Employed Income & Tax Tracker PDF.
Revenue so far: $0.
But here's what I learned:
— Most freelancers don't track expenses at all
— Tax season is their #1 stress point
— Simple tools still sell if the problem is real
Now I'm figuring out how to get my first 10 customers.
Any advice from people who've been here?
