From landlords to leading software providers

After buying their first rental properties in Rhode Island, Michael Monteiro and Dimitris Georgakopoulos co-founded Buildium, a software company with the purpose of streamlining property management. The missing piece? A payment processing solution. That’s where CSG Forte came in.

The Challenge

Buildium’s core customer-base of property managers needed a solution capable of processing a high volume of transactions with high price points, such as rent payments.

“We were looking for a solution that would help us increase adoption, and it was important for us to find a solution for ACH that would be cost effective for our industry,” says Georgakopoulos.

Why CSG Forte

CSG Forte had both the experience and expertise to offer an ACH solution — among other payment processing solutions — customized to Buildium’s specific needs. With CSG Forte’s dedicated implementation team and easy-to-use API keys, partnering with Forte became a no-brainer for Buildium’s executive team.

How CSG Forte Helped

CSG Forte provided Buildium with a tailored ACH solution that effectively addressed the challenges they had been facing since 2004. The partnership allows Buildium to avoid high percentage fees and offer their customers an effective, streamlined payment processing experience.

  • Integration: Within hours of receiving the product, the ACH solution was up and running.
  • Product offerings: Along with ACH, Buildium has been able to take advantage of CSG Forte’s credit card processing solution.
  • Communication: Buildium has benefited from having one primary point of contact with CSG Forte, providing a dedicated resource for timely responses.

The Results

Buildium has grown from a budding software option to the leading comprehensive software solution for property managers. Between 2016 and 2017, the company experienced an almost 35% year-over-year growth in transactions and a 39% year-over-year growth in dollars processed.

Hand-in-hand with CSG Forte, Buildium has been able to scale their business with individualized service, easy-to-use solutions for their end-user, and little processing downtime.


The relationship between Buildium and CSG Forte has withstood over fourteen years of industry changes. Reflecting on this, Georgakopoulos said, “With some of our other partnerships, there’s a lot of turnover on the partner side. Often we are the ones who end up having to educate the partners on how the relationship works. That hasn’t happened with CSG Forte. Having the same person on our account from nearly the beginning of the relationship has made a huge impact.”

Buildium has scaled their business quickly and increased revenue substantially. With CSG Forte’s dedication to providing a superior customer service experience and unparalleled understanding of ACH, the relationship between Buildium and CSG Forte is poised to excel in the next fourteen years — and beyond.


Over the past 17 years, CSG Forte has provided fast, secure and scalable solutions with one point of contact and integration.
