What does "you own your stack" mean, and why can per-seat SaaS cost more?

“You own your stack” means the software your business runs on belongs to you. You paid to have it built, and it is yours to keep, change, or move. Your “stack” is just the set of tools you use to get work done. Owning it is different from renting it month after month.

What these terms mean

Most business software today is rented. You pay a monthly fee and keep paying to keep using it. That model is called SaaS, which stands for software as a service.

A SaaS markup is the extra the software company adds on top of the real cost to run the service. That markup is how they make a profit, which is fair. But it means you pay more than the plain vendor cost.

Per-seat lock-in is when you pay a fee for every person who uses the tool. Add a staff member and you pay again. It becomes lock-in because your data lives inside the tool, so leaving later is hard and slow.

Why per-seat SaaS can cost more over time

Per-seat pricing can grow faster than the value you get. Here is why.

You pay again for every new user. Say a tool costs a set fee per person each month. Ten people is ten times that fee. Twenty people is twenty times. Your bill climbs as you hire, even if the tool is not doing more for you.

Prices rise. The monthly fee you signed up for is rarely the fee you pay in three years.

You rent forever and own nothing. After years of payments, you still own no asset. Stop paying and access stops.

Switching is hard. Once your data is inside a tool, moving it out takes work, so many owners just keep paying.

None of this makes SaaS bad. It makes it worth watching as you grow.

When SaaS is still the right call

To be fair, renting software is often the smart choice. There is no big build to pay for up front. Someone else maintains it, fixes it, and keeps it secure. For standard needs like email, accounting, or file storage, a well-made subscription is hard to beat, and building your own version would be a waste.

The rented model earns its keep when the tool is not special to your business and you are happy to let a vendor handle the upkeep. Sometimes SaaS simply wins, and we will tell you when it does.

What owning your stack looks like with SZTek

SZTek’s promise is simple. For the custom work we build, you own it. When your tool needs outside services like an AI model provider, a phone system, or hosting, you pay those vendors at their real cost. There is no SaaS markup added by us and no per-seat tax as your team grows.

So a custom AI application you own can serve two people or twenty for the same underlying vendor cost, because you are not paying per seat for the thing itself. We also offer our own product, EasyMark, when a ready-made tool fits your need better than a custom build.

Owning has trade-offs, and we will not hide them. There is effort and cost up front. You are responsible for the asset once it is yours, though we can help you plan for support and updates. And owning only pays off when the tool is a real part of how you work.

Most engagements start with a free first talk, then a short fixed-scope assessment so you can see the numbers before you commit. If the honest answer is that a subscription serves you better, we will say so.
