Solid CRM Development Work With Clear Communication Throughout

Sean Murphy / Head of Digital Transformation | Oct 20, 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 shared working builds regularly, so we could test early and give feedback before things were locked in.

Since launch, everything has been stable and our team has adapted to it quickly. We would definitely work with them again.

Project summary

We hired PositiveSine, Inc. 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. Overall it was a 8-month engagement.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I'm the Head of Digital Transformation at Greenfield Motors, a Automotive company based in Cork, Ireland. 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?
Our team was spending too much time on manual work. The goal was to customize our CRM and connect it to our website and billing system so they could focus on customers.
What services did the company provide for your project?
End-to-end CRM Development — from requirements and design through to deployment and a support period afterwards.
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 Automotive clients before.
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?
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?
How easy they were to work with. They were responsive, honest and genuinely interested in our success.
Would you recommend this company to others, and would you work with them again?
Definitely. We have already started talking about the next phase.

Quality work, a little slower than we planned

Sanne Jansen / Director of IT | Sep 15, 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

Feedback from our customers has been very positive so far. Their team changed one developer midway, which slowed things down for a couple of weeks. We would definitely work with them again.

Project summary

PositiveSine, Inc. was brought in to develop a field-staff app with offline mode that syncs back to our main system. The work covered requirements, design, development, testing and launch support. The engagement ran for about 7 months.

Easy to work with and very transparent on timelines and cost

Nikhil Menon / Co-Founder | Aug 24, 2026

We were very happy with how this project went. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We launched on schedule and have not had any major issues since. Happy to recommend them.

Reliable Blockchain Development Partner That Delivered What They Promised

Fatima Qureshi / IT Director | Jun 14, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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.

Feedback from our customers has been very positive so far. We would definitely work with them again.

Project summary

PositiveSine, Inc. was brought in to develop and audit smart contracts for a tokenized loyalty program. They worked alongside our in-house team, which mostly handled business requirements and testing. Overall it was a 3-month engagement.

Good value and a team that genuinely cares about the result

We were happy with the final result. They were upfront about what was realistic within our budget, which helped us prioritise the right features. They shared working builds regularly, so we could test early and give feedback before things were locked in.
