Great team to work with — professional, responsive and reliable

Ben Wright / Owner | Oct 15, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

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

Project summary

We hired Opus Online to run performance and load testing ahead of a big launch. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 3 months from kickoff to launch.

Questions & Answers

Please describe your company, your role, and the industry you operate in.

I work as Owner at Summit Utilities Ltd. We operate in Energy & Utilities and most of our customers are in and around Birmingham, UK.

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

Our existing setup was holding us back. We wanted to run performance and load testing ahead of a big launch before our busy season.

What services did the company provide for your project?

Mainly Quality Assurance & Testing. 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?

They had relevant experience in Energy & Utilities and their proposal was the clearest of the ones we received.

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

They understood our goals quickly, partly because they had worked with Energy & Utilities clients before.

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

Good. Weekly calls, regular updates and a shared board meant we always knew where things stood.

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

Mostly. One milestone slipped by about a week, but the final delivery was on schedule and the budget held.

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

Our team saves several hours a week, and we have had very few issues since launch.

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?

Definitely. We have already started talking about the next phase.

Easy to work with and very transparent on timelines and cost

Daan de Vries / Program Manager | Aug 30, 2026

We were very happy with how this project went. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.

We launched on schedule and have not had any major issues since. We would definitely work with them again.

Project summary

We hired Opus Online to build a demand forecasting model on top of our sales data. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 7 months.

I work as Program Manager at Redwood Fabrication BV. We operate in Manufacturing and most of our customers are in and around Eindhoven, Netherlands.

We needed to build a demand forecasting model on top of our sales data, and we didn't have the in-house capacity to do it ourselves.

We can now handle more volume without adding staff, which was the main goal.

The consistency. Same team, same standard, from the first week to the last.

Honest advice and solid execution

Lauren Graham / CEO | Jun 28, 2026

Opus Online did good work for us, and we would use them again. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The result looks great and performs well, and our internal team found it easy to take over. Their team changed one developer midway, which slowed things down for a couple of weeks. We are already discussing the next phase with them.

Project summary

Our company worked with Opus Online to provide ongoing monitoring and support for our cloud infrastructure. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 6-month engagement.

Good work overall, with a few bumps along the way

Mark Foster / Managing Director | Jun 23, 2026

The final product works well for us, although the process could have been smoother. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We are already seeing better numbers than before the project. Their team changed one developer midway, which slowed things down for a couple of weeks.

Happy to recommend them.

Project summary

We hired Opus Online to provide ongoing monitoring and support for our cloud infrastructure. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 4 months.

Capable Quality Assurance & Testing team — happy with the end result

Dan Hughes / Director of IT | Mar 06, 2026

We got a good result in the end, but the road there had a few bumps. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Feedback from our customers has been very positive so far. Estimates on a few features were optimistic and those took longer than planned.

I would recommend Opus Online to anyone looking for a dependable Quality Assurance & Testing partner.

Quality work, a little slower than we planned

Owen Leblanc / CEO | Feb 27, 2026

We got a good result in the end, but the road there had a few bumps. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

It has made a real difference to how our team works day to day. We had to follow up a few times on smaller bug fixes after launch.

We are already discussing the next phase with them.

Project summary

Our company worked with Opus Online to set up automated testing for our web application. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 2 months.
