plus minus Delivered a Quality Software Development Solution on Time

Jason Hayes / Co-Founder & CTO | Jul 31, 2026

Our experience with plus minus was really positive from start to finish. 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. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Since launch, everything has been stable and our team has adapted to it quickly.

I would recommend plus minus to anyone looking for a dependable Software Development partner.

Project summary

plus minus was brought in to develop a scheduling and dispatch tool for our field team. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 7 months from kickoff to launch.

Good results, communication improved as the project went on

The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

Overall the project was a success, though it was not without some challenges. 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 developers were knowledgeable and made a few suggestions that ended up saving us time and money.

We are already seeing better numbers than before the project. We had to follow up a few times on smaller bug fixes after launch.

Great Experience With plus minus on Our UI/UX Design Project

Amanda Carter / General Manager | Jun 28, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They shared working builds regularly, so we could test early and give feedback before things were locked in.

A reliable long-term partner for our tech needs

Siddharth Desai / Co-Founder | Jun 03, 2026

plus minus did good work for us, and we would use them again. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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. There were some early misunderstandings on requirements that took a few rounds to sort out. We would definitely work with them again.

Would happily work with them again

I would rate this engagement highly on almost every front. 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.

Quality work, a little slower than we planned

Ashley Brooks / CTO | Jan 26, 2026

The final product works well for us, although the process could have been smoother. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. Documentation at handover was a bit thin and we had to ask for more detail.

I would recommend plus minus to anyone looking for a dependable Mobile App Development partner.

Project summary

plus minus was brought in to rebuild our existing mobile app, which had poor reviews and frequent crashes. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 6 months.
