Also listed in Donor Management, Nonprofit Payment Gateway, Nonprofit CRM, Admission-Based Nonprofit

I absolutely loved the trial experience with Donorbox. Setting up Donorbox was extremely easy, as I could integrate and connect our PayPal account within minutes, include our branding colors, and incorporate our messaging for donor communications. It was surprisingly simple. Donorbox effectively solves the problem of providing an easy way for us to communicate donation methods to potential donors, which saves time in receiving donations for our nonprofit. I find the ease of use and the simplicity with which people can donate via our site most valuable, along with the quick integration with PayPal for fast donation receipt. The low cost of Donorbox is another appealing factor, making it a service I would consider using again in the future. My satisfaction with Donorbox is so high that I would rate my likelihood of recommending it to others an eleven out of ten. Review collected by and hosted on G2.com.

I love the customer service team at Zeffy; they are excellent, reply quickly, keep me informed of any troubleshooting, provide excellent training tip videos, and make important changes based on clients' feedback.

Stampli is the only finance operations platform centered on AP.
Also listed in Procure to Pay, Accounts Payable (AP) and Spend Analysis, Invoice Management, Strategic Sourcing, Purchasing
I believe Stampli will help my company hold our accounting department accountable (haha) for making sure our vendors are paid on time and that invoices are being sent to the correct department. The AI side of things makes invoices very easy to use, and has seemingly helped our accounting department with matching PO's to who they're supposed to go to. We had a hour long training session, but everything is honestly so easy to use and implement that we all feel we didn't really need it. I haven't had to use customer support yet, strictly because of how simple it is. This has been a slow month for us, so I haven't used it a ton, but I will say that I haven't had any issues of invoices not getting paid since starting Stampli.

Also listed in Payment Processing, Accounts Receivable, Billing

Paystand was our first step into the digital payments space. We handled ACH business transactions before, but that process was incredibly arduous and time consuming. We find the most value in the Paystand Autopay feature in NetSuite. Enrolling a customer is very simple, and collecting their payments is even easier. We went from manually charging about 80 customers using our legacy ACH, which took us 2 full a days per week, to running over 275 customers on autopay effortlessly. What I like most about it is that is very configurable. We could not use a rigid solution that only ran transactions a single time every week or month. However, paystand lets us decide when to turn on Autopay per customer and even turn it on/off for certain invoices, which makes the transition for customers very seamless. It has tremendously reduced the amount of time and effort we spend on ACH transactions, and the value only increases the more customers we add. Review collected by and hosted on G2.com.
