A letter from the founder

# Why is Stacks free?

From the founder of Stacks · August 2026 · 4 min read

I've been a small business owner for more than 25 years.

I know what it feels like to watch a dozen software subscriptions drain the account every month. To pay for a CRM, a scheduler, an invoicing tool, an email tool — and still keep half the business in a spreadsheet, because none of it talks to each other.

I've also spent those 25 years building software. CRMs, mostly. Systems that ran real companies — mine, and ones I helped run.

Then AI changed the math.

Building good software used to take a team and a year. That's why it was expensive, and that's why you rented it. Today, as someone who has built these systems for decades, working with modern AI tools I'm able to build in months what used to take years.

So Stacks wasn't a moonshot for me. It was the system I'd already built a dozen times — finally built the way I always wanted, flexible enough for nearly any small business. A contractor's pipeline. A shop's invoices. A practice's front desk. A studio's client list.

And here's the part most software companies won't tell you: once it's built, letting you use it costs almost nothing. Software is strange that way — expensive to create, nearly free to share.

So I had a choice.

I could charge you per user like everyone else — and spend it the way everyone else does. The downtown office. The sales team whose quota is you. The booth at the trade show. The ads that follow you around the internet. That's what a software subscription really pays for, most of the time. It isn't the software.

Or I could skip all of it. Stay lean, keep building with AI instead of hiring a sales floor, and give the software away.

I picked "help you."

How I actually make money — so you never have to wonder:

- **Stacks is free.** Not a trial. It doesn't expire, and it isn't a crippled demo. It's the real product.
- **If you want more, $99/month — AI Pro — turns on the AI:** drafting replies, scoring your leads, answering questions about your business, handling the busywork across every module. It comes with priority support, too, for when you'd rather talk to a person. The free version runs your business; AI Pro works alongside you.
- **If you outgrow it** — or you'd simply rather we set it up, train your team, and make it just work — we'll build you a [custom version](https://stackscrm.com/#custom) shaped around your exact business, and port your data straight in. A handful of businesses a year make that jump, and they keep the lights on for everyone else.

That's the whole model. No ads. No selling your data. Your customer list is yours — export it any day, no hard feelings.

After 25 years of *being* the small business, I'd rather a thousand owners run on something I made than ten sit through a sales pitch.

Use it. Run your shop on it. Tell me what breaks.

That's why it's free.
