Best online ticketing platform I've used!

5.0 last month New

Comments: The customer service has been exceptional. It's clear that the staff cares and wants to help.


Onboarding is quick and easy. You do not need to be super computer savvy to have yourself up and running with ticket sales online.


There was a delay before we could ask for donations because we are a US nonprofit and initially it was only offered to organizations with Canadian banks. I still used it for ticketing as I preferred it to other online options. Now I can get donations deposited directly into our bank account..

Glad we made the switch to Simplyk

Comments: Their platform is easy to set up, and if I have any questions they get back to me within a few minutes. They also never made me feel like my questions were unwise. Plus, anything that the platform did not do in the beginning, it now does. It wasn’t months that I had to wait for them to change either, it was often very quickly.


I love that I can embed the ticketing platform into our website. I’m not sure if Eventbrite now does this, but at the time it didn’t. It is very good for us that we don’t have to send our purchasers to a different website. Our ticket purchasers mentioned that it’s great that they’re not redirected to another page to purchase. They’ve also said that the platform is very easy to use. We haven’t had any complaints, and we’ve had a few ticketed events in the past few months.


I find that the form that we embed on our website can sometimes be finicky design-wise. Although, I know a lot of it is our website. I'm just picky about how everything looks.

Five Stars

4.0 4 weeks ago New

Comments: Zeffy is an incredible product and has been a real game changer for CMHA Toronto. Donor relations, reporting, and receipting are all vastly improved by this product and the elimination of transaction fees has already saved us tens of thousands of dollars in a short time.


I was initially interested in Zeffy due to the promise of zero transaction fees. This is a very appealing feature for donors who always appreciate knowing that 100% of their donation is going to the charity. I had been using another product that charged nearly 5% in transaction fees. I soon began using Zeffy for anything that required a pay portal from the donation page on our website, to campaign pages for third party events. I have also used Zeffy for ticketing, and it has been a flawless experience.


The templates can be a bit limiting, for instance if I want to employ a video and info graphic on the same page, you need to click on the box that says 'what impact will this donation have' in order to see the graphic. It's not the worst setup, but it could be improved.

Great product that saves money

4.0 2 years ago

Comments: Using Simplyk has been a great experience, especially in saving us money but also in providing us with a great platform to do our fundraising. Their customer service team is one of the best I've ever dealt with, and I really appreciate having an account manager I can go to for assistance who is very quick to respond and do all they can to help us.


The biggest selling feature of Simplyk for non-profits is that they cover the costs of all credit card transaction fees, which saves us a lot of money. On the user end, it's a very clean-looking website, and fairly simple to use. On the back end, setting up ticket pages and campaigns is straightforward and pulling reports is not very complicated. Integrating with Stripe was quick and easy - our accountant loves it!


Since Simplyk seems to be a newer software, it is still missing some features that would be great to have and it's sometimes not as robust as we would like. It does not allow users (for us, people who are fundraising on our behalf) to be able to send emails to their sponsors in order to thank them for their donations. It would be nice to have more administrator control as well - there are some things I need to email to Simplyk team to do for me because I can't do them myself.

Zeffy is a superb option for small non-profit organizations!

5.0 2 months ago New

Comments: Zeffy has made it possible for our small non profit retreat ministry to stay affordable for our participants.


I love the ease of set up to accept donations, registrations and payments for our retreats. The fact that there are no fees allows us to keep our cost low while our financially secure participants can make donations to cover any fees Zeffy incurs.


There have been no cons I've experienced.
