Reviews & Reputation
Paychex
Reviews for Paychex are mixed. As a SaaS (software as a service), there aren’t locations to tie Google reviews to, but Trustpilot reviewers give Paychex 1.5 out of 5 stars.
The positive reviews mention that the software is easy to use. Paychex’s platform uses step-by-step processes and plain language, making setting up and running payroll feel simple for new business owners.
Just like with other large payroll providers, the negative reviews say that human support is unhelpful and unresponsive, leaving them waiting in a phone queue and struggling to resolve time-sensitive or advanced issues. And, on our end, we’ve had plenty of clients who have come from Paychex. We personally found a few instances of payroll deductions and Minnesota’s PFML accounts not being set up properly (due to clients being forced to do this on their own without the proper knowledge). We also saw some owner wages being taxed incorrectly (often in unemployment opt-in states when the owner does not opt in but still has their wages submitted and pays unemployment).
Long story short, Paychex can be a great choice for business owners who are experienced in running payroll or confident that they can navigate it with minimal error.
CSI Accounting & Payroll
Reviews for CSI Accounting & Payroll are overwhelmingly positive. We don’t have a Trustpilot listing, but we have Google reviews for our Minnesota and Maryland offices. Both locations have 4.9 out of 5 stars.
Our positive reviews mention the quality of service exceeding the payroll industry norm. They also say that they’ve formed close relationships with their dedicated Payroll Specialists, and they trust them fully.
We don’t get negative reviews about our payroll service because of our focus on accuracy, error resolution, and customer service. We also handle difficult setups for our clients to avoid mistakes and frustration. We have only a few bad reviews, and they all mention our monthly accounting service. This article explains what the reviews have in common.

Cost
Paychex
Paychex and other payroll giants like ADP do not clearly talk about pricing. There are no averages or ranges, not even to differentiate the five different tiers of payroll and HR service. To find out what it might cost you, you need to talk to their sales team.
We don’t see any reviews that complain about the cost, so it’s probably a realistic price range for payroll SaaS (software as a service).
CSI Accounting & Payroll
We largely price our payroll service per feature. No tiers, and no paying for features you don’t want or need! An average month of payroll fees can range from a little under $100 to $500+, and our average payroll client sits at a fee of around $275 per month.
Estimate your investment here:
Remember, we don’t know the cost of Paychex, but if CSI costs more, it could be because we’re not just a SaaS (software as a service) like Paychex. We’re an actual service where you’ll have a dedicated Payroll Specialist and their direct contact information. You get support every step of the way, giving you total peace of mind.
If that sounds like what you need, then you might find the best value with CSI Accounting & Payroll.
