About Sustain
Sustain is a robust Fundraising Management Software program that began early development in January of 2004 and was released December of 2007. Much of Sustains’ design came from feedback and needs of end users, and not the design of technicians.
Sustain offers a whole new outlook on fundraising management software. Designed with the user in mind, Sustain allows for a professional transition into properly managing your nonprofit organization. From entering donations and pledges, to simple mail marketing, to distinctive reports, Sustain guides the user from start to finish seamlessly.
School Fundraising, Membership Associations, Child Services and Healthcare became the building blocks of the core design and feature set of Sustain. Today we thrive on the good nature of our customers and we continue to build for the future. Listening to what our customers’ needs are allows our product to be built around you and your organization.

Great Customer Service Experience

In terms of Alumni Relations the software is geared more toward fundrasing, but with the great level of customer support I have received, it does the job.

Very Small Company, Very Poor Implementation
2
Again the software itself wasn't that bad, it was the implementation/migration from our previous system that was terrible and the reason we were not successful with Sustain. They set an expectation that we could just send them the SQL database from our previous system and they were experienced enough with that system to take it from there, that they had done this before. That's not at all what happened, the data got only half migrated and it was on me the customer to fill in the holes (though we paid them for implementation services). They had very little in terms of documentation, they had a migration template but didn't give it to me, I had to find it. Very disorganized and immature company, very little documentation, cannot be trusted to move all the data over you need to be successful. Also we had to ask for a new trainer, the first one we got was extremely defensive and gruff, can't believe he's in a customer-facing role, simply does not have the temperament for it.

Overall the software provides me with the information I need. Because it is so multi-faceted, attending training is mandatory. Even after my initial training I find myself clicking around to intuitively get, for instance, the report I need. It would behoove new users to make a list of all the ways you plan or foresee using the product and choose the level of training necessary. And take copious notes because you'll need them for tasks that you do only periodically. I'm certain I'm not using it to its fullest capabilities.

From the first day Sustain was installed I have found the software easy to use. And the rarity I have encountered a question, great customer service!

We purchased Sustain through Rediker because we were told that it would interact with FinACS. While I am still under the impression that there can be communication, we can't figure out how. Communication only goes one way, and that is a concern because we would be transferring accounting information from Development to Accounting. Not comfortable. Additionally, there seems to only be one person who can help us understand Sustain, and he is not good at customer service. Every conversation I have had with him has been uncomfortable at best. I am bright and pick up software easily and still always leave my calls with him feeling stupid, and yet doing everything in my power to not call back, just figure it out on my own. I am sure Sustain has more capabilities than I know, but I feel like I need to take an Access class in order to really utilize the program. The price we paid for the product and the service is outrageous in my opinion and we are almost 2 years in and just barely scraping by with our information. Certainly, I can't find the reports I need and customizing just seems overwhelming. If I had this decision to make over again, I would not choose Sustain. Unfortunately since we've already invested so much, changing just isn't an option at this point. We were brought in by Rediker, but your relationship with them is tenuous at best. Their customer service, which is fantastic, can't help me with your product. And no one REALLY understands how the programs are supposed to integrate. I would carefully consider that fact when cross selling.

We use the software as a comprehensive donor tracking tool. We have come to learn no other school uses it to the degree we do and it is very evident. There are constant issues with the system and upgrades. Not a fan at all.

Most unreliable software
1
Seacrest has had more issues with Sustain and although we call for customer support, it typically falls short. We have been told multiple times the problem is on "our end" or with Finalsite or Admin+. We have learned to work around to solve issues on our own. Reporting functions are almost non-existent and when they do work the report is, more times than not, incorrect. Edited information is often reverted back to previous information. General ease of is not user-friendly. The dashboard appears to be from 1970. We are budgeting for replacement software.

it has been a fairly positive experience. it would be helpful to have free, regular, short web based training sessions on specific topics (similar to what rediker does for their software) more documentation, with samples of best practices some parts are a little clunky and difficult to navigate. perhaps info when hovering (i.e., "use xx for xxx")
