I ran a web agency for 15 years before building a SaaS. Here's what I wish I knew earlier.

For 15 years I built ecommerce stores for clients at my agency in Italy. Good business, good clients, but always trading time for money. Last year I took a problem I kept solving manually for clients, writing product descriptions, and turned it into a SaaS product.

The transition from agency to product was harder than I expected. A few things I learned the hard way:

1. Your agency clients are NOT your SaaS target market. They want custom work, not self-service tools. Different mindset entirely.

2. Pricing is a completely different game. In agency work you price by the hour or project. In SaaS you price by the value delivered — and underpricing is the default mistake.

3. Marketing yourself feels wrong. After 15 years of marketing other people's businesses, promoting your own product feels awkward. You have to get over it fast.

4. The loneliest part is making decisions alone. In agency work the client tells you what to build. In SaaS, you decide — and you live with the consequences.

5. Being bootstrapped is a superpower, not a limitation. No investors means no pressure to grow at all costs. You can build what actually matters.

I'm still early in this journey and learning every day.

For those of you who made the leap from services to product: what was the hardest part for you?
