Financial Controller

As a foreign company moving into the US market I'm glad we chose OnPay. They have been great at making everything smooth from helping us get set up with payroll to benefits for our employees.

Small business owner

User-friendly, excellent customer support, super easy on a small budget and I am 100% comfortable in leaving everything in their capable hands. Simply click a button on payday and it's done.

Owner

Alway friendly staff that is eager to help answer any questions and get us to a resolution. Software is simple and packed with features.

Director of Operations

The communication, information, help & kindness shown throughout the process has been a real change from our last experience. The response time is super quick too.

owner

Sometimes new employees miss the part about setting up direct payment into their accounts. It must not be obvious, because about 1 out of 3 will miss it.

President

Super easy to get started with it and super easy to use. Love the payroll feature.

Minister

It has made a big difference for my organization and we have saved a great deal of money compared to using an in - house bookkeeper doing it.

Administrator

Not only is the software a joy to use, the customer service is amazing.

I have been using OnPay for over 4 years now. It has always been easy to use and they have had excellent customer service.

Marketing Coordinator

I love how easy it is to navigate the software. It's so intuitive and simple to use.

Vice President Of Human Resources

The system is super easy to use. Not only for admin but for the employees as well.

Easy of use, fast on boarding process, easy to take administrative actions and excellent integrations.

Payroll Admin 

HR integrations, time management, workers compensation, benefits, and more. I love the challenge to incorporate and enhance new reports and learn the value of OnPay’s intentions for their customers.

Its easy for a non tech savy person to use which was important. Also like my taxes are auto filed for me.

I also like the ability to import into QuickBooks.

Office manager 

Also, there was a problem with payroll being processed twice within two minutes from each other. There should have been a pop up stating you already processed a payroll.

I hate paperwork and don't have a big enough operation to justify hiring a book keeper.

After that, the website would no longer let me log in with my password. I could only login with just my email, which felt a little sketchy.

Executive Coordinator

The implementation team was great when we were getting this started as they were very helpful and answered all of our questions.

Office Manager

This product was recommended by our CPA who uses it for his own office. That recommendation was good enough for us and it has proven to be an invaluable asset to our business.

VP Customer Success

I never criticize publicly about an organization but this one was so very unprofessional and even made worse by the outrageous fees they charge.

Recruiter

Great service, great app, great website. User friendly, leaves me with no questions after checking my breakdowns every pay period.

Marketing Director

It can be a problem to login to the work site which is frustrating when trying to clock in or clock out on time.

Director of People Operations

Just about everything else. Its not user-friendly, its customer service is terrible and we get so many complaints for employees, as the admin I have limited resources to help.

Human Resources

We are a month into the implementation process with Paychex and just processed our very first payroll. So far the experience with Paychex and their implementation team has been outstanding.

Analyst

It's easy to use daily, and everything is very easy to find. I like that I can find any documents I need to sign, and complete them with ease.

Marketing

I guess the positive is that it looks nice visually. It gives you the info you are looking for with some searching.

Paychex Flex offers a variety of functions and features that are ideal to our company. The on boarding was easy thanks to their great support team.

Marketing Associate

Paychex Flex allows you to see all of your paychecks in one place, see deductions, tax documents,  as well as other information like your employment anniversary. The app is wonderful as well.

Lead recruiter

Overall expereince was great. Userfriendly and worth the money.

HR Specialist

Then I started a new job where they use PayChex, talk about old and outdated. I hate that I literally have to ask someone to change the taxes for one of our employees and I can't do it myself.

Virginia Field Organizer

It is a perfect portal for all those things and more. It's really easy and intuitive to move from one dashboard to the next.

Director of HR

For the most part, Paychex Flex is a wonderful integrated HRIS product. It is truly full cycle, from recruiting to succession planning, training, through the end of employment.
