the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I am a product manager at an app growth platform offering global services.
What challenges were you trying to address with XOOR?
We needed a partner to create an invoicing solution for us.
What was the scope of their involvement?
XOOR developed an invoicing platform for us. We had different invoicing processes for our different global invoicing entities and were looking to automate and unify our processes. They used JavaScript, SQL, and React Native.
What is the team composition?
We worked with 4 to 5 people.
How did you come to work with XOOR?
I started a web search on agencies in Argentina that could do this development for us, and I found XOOR on Clutch. They have very good references so they seemed like a good choice for us.
How much have you invested in them?
We spent about $30,000.
What is the status of this engagement?
We started working with them in January 2020 and the project lasted about 6 months.
What evidence can you share that demonstrates the impact of the engagement?
The quality of the platform is great; we’ve tested it several times and it works just perfectly. Whenever we encountered any setbacks they were there to solve problems.
The impact on our company has also been great. This used to be a manual process and required a very large amount of time and human resources — with the platform, we have saved a lot of time and resources.
How did XOOR perform from a project management standpoint?
We used Slack to communicate, as well as Zoom and Google Meet. We used a Gantt diagram for project management and everything went very well. They were very flexible and we achieved very good results.
What did you find most impressive about them?
They were always pending on every detail, and the quality of their work is just great. XOOR was very engaged with our project and had many innovative ideas.
Are there any areas they could improve?
The conclusion of the project lasted a bit longer than it was initially expected, it wasn’t a big issue and was a natural consequence of changes but maybe they could do a more precise estimation of the length of the projects.
XOOR’s solution has saved the internal team a great deal of time and resources, allowing them to focus on their own business. Throughout the project, the team was attentive, reliable, and professional, ensuring project success.
