For what projects/services did your company hire Stackk?

Construct a channel to obtain formal and legal Social Investments through our Jotforms aplication and our preferred payment processor

What were your goals for this project?

  • Build a coding based on Corvid that allow us to link our Jotforms application to Wix backend and then to our payment processor.
  • Make it responsive and friendly to the user
  • The impact is significant as it allow us to formalize our funding channel for Social Investments through our website.

How did you select this vendor?

We've considered many other vendors and we made an analysis based upon their understanding of our needs and their description of possible solutions. Finally we analyzed if the cost was affordable. Based on these we decided to hire this vendor.

Describe the project and the services they provided in detail.

We told the vendor about our need and general guidelines. Upon this he analyzed the situation and proposed to us a possible solution which was subject to some risks. We decided to carry on with the first part of the project which was the linking of Jotforms application to Wix backend. Once this was done successfully we proceded to the integration with our payment processor (MercadoPago) while using Corvid coding language. The vendor did the integration successfully. Afterwards he offered to make it responsive and gave us useful tips on frontend design.

What was the team composition?

We always communicated with Al Sanchez who was the project leader from STACKK. He and his team worked actively on different parts of the project. The size of the team did not change over time.


Can you share any information that demonstrates the impact that this project has had on your business?

This project enable us to formalized legally one of our main funding channels: Social Investments. These must be done through a legal contract which can only be made using a particular form from Jotforms. With this, we could expand our funding in a formal and legal way and have all of our investments well documented and registered to regulatory norms. The system is robust and efficient and has fully accomplished our expected results.

How was project management arranged and how effective was it?

Communication and updating was excellent. Al was highly available and we had conversations through Skype and Whatsapp. He constantly explained meticuoulsy every single step he was making and which were the futher steps required. Compliance with deadlines was optimal.

What did you find most impressive about this company?

They’re able to adjust to your needs and offer a unique, personalized solution for highly complex projects. Their price is affordable for non profits, and I don't think we could have made it with another vendor considering out limited budget. The company is always available for any changes and improvements that needs to be done, without hesitation at all. Their communication is excellent and the fact that they are always ready to help is extremely appreciated.

Are there any areas for improvement?

I currently don't know any areas for improvement.
