Is it still worth building an invoice generator when there are already so many in the SaaS market?

Hi

I’m a solo dev and I’ve already built about 75% of an invoice generator SaaS for freelancers and small business owners.

But lately, I’ve been questioning is it still worth finishing and launching it? There are already tons of invoice tools out there.

My version focuses on:

• Minimal and fast UI

• Simple subscription-based pricing (no complex tiers)

• Privacy-first (no data selling, no tracking)

I started this project because I wanted something straightforward and clean for small creators and freelancers without unnecessary complexity. But now I’m wondering if that’s enough differentiation in 2025.

Would love to hear your thoughts should I keep building or pivot the idea a bit?
