Reliable Software Development Partner That Delivered What They Promised

Abdullah Al Harbi / General Manager | Aug 04, 2026

Overall we had a good experience working with Sinersys. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

We launched on schedule and have not had any major issues since. Their team changed one developer midway, which slowed things down for a couple of weeks.

Overall, a team we trust and plan to keep working with.

Project summary

We engaged Sinersys to rebuild an internal order management system that had outgrown its original design. The work covered requirements, design, development, testing and launch support. The engagement ran for about 8 months.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I work as General Manager at Trueline Projects Co. We operate in Construction and most of our customers are in and around Dammam, Saudi Arabia.
What specific problem or business challenge led you to hire this company?
We needed to rebuild an internal order management system that had outgrown its original design, and we didn't have the in-house capacity to do it ourselves.
What services did the company provide for your project?
Mainly Software Development. They also helped with the technical planning and a few integrations with our existing tools.
Why did you choose this company over other providers you considered?
Their pricing was fair and they were honest about timelines instead of just telling us what we wanted to hear.
How clearly did the company understand your requirements and business goals?
They understood our goals quickly, partly because they had worked with Construction clients before.
How was your overall experience with their communication and project management?
Communication was good overall and improved further once we settled into a routine.
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?
We can now handle more volume without adding staff, which was the main goal.
What did you like most about working with this company?
That they were proactive — they suggested improvements instead of just doing what was asked.
Would you recommend this company to others, and would you work with them again?
Yes, I would recommend them and we plan to work with them again.

Professional team that made a complex project feel manageable

Nicole Fisher / VP of Engineering | Jun 28, 2026

I would rate this engagement highly on almost every front. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They were upfront about what was realistic within our budget, which helped us prioritise the right features. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline.

It has made a real difference to how our team works day to day. We would definitely work with them again.

Project summary

We hired Sinersys to connect our equipment to a cloud dashboard so we could monitor it remotely. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 7 months.

We are already seeing better numbers than before the project. Happy to recommend them.

We were very happy with how this project went. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline.

A reliable long-term partner for our tech needs

Amit Desai / Co-Founder & CTO | May 03, 2026

I would rate this engagement highly on almost every front. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They shared working builds regularly, so we could test early and give feedback before things were locked in. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

The IoT Development work has already made a noticeable difference — tasks that used to take hours now take minutes.

If you need a team that communicates well and delivers, they are a good choice.

Exceeded our expectations on quality and communication

Lerato van der Merwe / Founder & CEO | Apr 29, 2026

Our experience with Sinersys was really positive from start to finish. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

It has made a real difference to how our team works day to day.

We would definitely work with them again.

Project summary

We hired Sinersys to take over manual and regression testing before each release. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 6 months from kickoff to launch.

Great Experience With Sinersys on Our CRM Development Project

Ella Walker / Co-Founder | Apr 09, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The CRM Development work has already made a noticeable difference — tasks that used to take hours now take minutes. Overall, a team we trust and plan to keep working with.

Project summary

Our company worked with Sinersys to customize our CRM and connect it to our website and billing system. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 2 months.
