Hannah Hughes / Director of IT | Oct 13, 2026

The AI & Machine Learning work has already made a noticeable difference — tasks that used to take hours now take minutes. We would definitely work with them again.

I'm the Director of IT at Greenfield Motors, a Automotive company based in Reading, UK. I look after our technology and work closely with outside partners on bigger projects.

What specific problem or business challenge led you to hire this company?

We had tried to do this internally and it stalled. We needed specialists to build a demand forecasting model on top of our sales data.

What services did the company provide for your project?

End-to-end AI & Machine Learning — from requirements and design through to deployment and a support period afterwards.

Why did you choose this company over other providers you considered?

A colleague recommended them, and our first calls confirmed they understood what we needed.

How clearly did the company understand your requirements and business goals?

Well. There were a couple of points we had to clarify early on, but after that they were spot on.

How was your overall experience with their communication and project management?

Very responsive. We usually heard back the same day, even with the time difference.

Did the company deliver the project on time and within your expected budget?

Yes. The only extra cost came from features we added ourselves, and they quoted those fairly.

What tangible results or business impact have you seen since the project was completed?

It is still early, but the numbers are trending in the right direction and the system has been stable.

What did you like most about working with this company?

That they were proactive — they suggested improvements instead of just doing what was asked.

Yes, I've already recommended them to a couple of people I know.

Professional Web Development Team, Smooth Delivery From Start to Finish

Derek Ramirez / Co-Founder | Sep 12, 2026

The project went well overall. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

We are already seeing better numbers than before the project. We had to follow up a few times on smaller bug fixes after launch. I would recommend FIS-SST Sp. z o. o. to anyone looking for a dependable Web Development partner.

Project summary

Our company worked with FIS-SST Sp. z o. o. to build a customer portal where clients can log in, track orders and download invoices. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 2 months.
