Worst app ever

Pos trash never works right

Avoid Paychex at all costs.

Absolutely horrendous. Moving our company to Paychex’s PEO platform was the worst business decision I have ever made.

I originally used Paychex because it previously had an exclusive arrangement with the Florida Workers’ Compensation Joint Underwriting Association for agency billing. Although its payroll system and customer service were already disappointing, our company needed that agency-billing capability. As we grew, a Paychex salesperson persuaded me to “upgrade” to its PEO platform—a decision I deeply regret.

After moving to the PEO, I encountered serious and recurring problems, including:

Failure to properly initiate and process E-Verify cases.
Employees shown in the Paychex system as authorized for employment even though, when I investigated, no corresponding E-Verify case appeared to exist.
Failure to remit workers’ compensation payments properly.
Erroneous fees and apparent overcharges.
Frequent system inconsistencies, errors, and unexplained “bugs.”
An inability or unwillingness to provide a clear, itemized accounting of the services, fees, and rates applied to our account.
Changes to rates and contractual terms during the agreement.

The platform that was sold as a “premier professional” solution immediately created an enormous administrative burden. I began spending approximately 10–15 hours every week identifying errors, reconciling conflicting information, documenting problems, and tracking down people who might be able to correct them.

Paychex appears to operate through numerous siloed departments that do not communicate or integrate effectively. Over the course of this experience, I dealt with dozens of employees across multiple departments. Many could explain only a narrow portion of their own process and could not explain how it connected to the other departments their work depended upon. I was repeatedly transferred, redirected, or given conflicting answers, while critical issues remained unresolved.

The most alarming issue involved E-Verify. After discovering that Paychex’s system reflected employees as employment-authorized even though I could not locate evidence that the required E-Verify cases had actually been created, I requested termination of the PEO agreement. Instead of taking responsibility for the severity of the problem and allowing us to leave, Paychex responded by seeking a termination penalty of approximately $25,000.

In my experience, Paychex accepts little meaningful responsibility for the accuracy or functionality of the platform it sells. When its systems, billing, or internal processes fail, the customer is left to identify the problem, prove that it occurred, navigate multiple disconnected departments, and spend hours pursuing a correction. Meanwhile, Paychex continues charging substantial fees for services that are supposed to reduce—not multiply—an employer’s administrative workload and compliance risk.

I would strongly caution any business owner considering Paychex PEO to disqualify the company as a candidate. If you are already unfortunately contracted with this company, demand, in writing, a complete itemized fee schedule; all termination provisions; all workers’ compensation responsibilities; the precise E-Verify workflow; service-level commitments; and restrictions on mid-contract rate or term changes. Carefully audit everything Paychex processes on your behalf. Do not assume that a status displayed in its system means the underlying filing, payment, or compliance action was actually completed.

Based on my experience, I cannot recommend Paychex or its PEO platform.

Glitchy login process

This app and the company are horrible with registering your credentials and recognizing the device you’re logging in with. Every time I open this app to log in so I can punch in for my job, it asks me for a verification code even though the remember my device box is checked on. Makes it all the more annoying to punch in and can cause a delay in the process if there network or app is down. It even started doing this to me on my work computer at the office I work at. Talking to their customer support was a joke, as the agent I talked to basically told me they couldn’t do anything and only suggested to delete the app and reinstall it, which didn’t fix anything and I doubt he ever brought the issue up to the company’s development team.

PLEASE FIX

the payactiv button is gone

Functionality

This is without a doubt in my mind one of the worst apps I have ever used. It never allows me or anyone else at my job to login correctly. And will ask for a verification code each and every time even after checking remember my device. Almost every day when anyone here goes to clock in or out for the day or lunch it does not register and makes you do it a few times be fore it works

Text verification

Every time I sign in it has me do the text code verification. Every time. Multiple times a day.

time consuming & spammy

first off, it logs you out after 30 minutes and i waste time trying to log in & verify with text message at every. single. timepunch. second off they send you a bunch of spam emails about companies they "partnered with" which is very annoying & makes me think theyre selling our information to them and disguise it as "benefits"
if i could force my company to stop using this i would.

frustrating trash app

always glitching. i have to close the app and open it multiple times just to sign some documents. It logs me out everytime i close the app and when i log in, it sends a verification code to my phone every single time even though i check "remember device" every time

Genuinely don’t know how it has a 4.8

only thing it works for is punching in and out. If your plans are to look at anything else. Just go to a laptop. If you’re downloading this you probably have to, I’ll say use notifications and punching the best bc everything else works when it wants to.

No ai

Get rid of the stupid ai stuff it’s unnecessary

Really helpful and kind

Horrible Buggy App

This is one of the worst work apps I’ve used. Clocking in, clocking out, and correcting punches are basic functions, yet Paychex somehow makes all of them unnecessarily difficult.

I’m constantly forced through two-step verification, even though I select “Remember this device” every time. Face ID also never works reliably, no matter how many times I set it up.

Now they’ve added AI to editing punches, which nobody needed. It has made a simple process more confusing and buggy, and the missing-punch screen currently doesn’t even load properly, making it impossible to correct time.

Stop adding unnecessary features and make the basic functions work. A timekeeping app should make clocking in easier, not harder.

Best out there

This is by far the best payroll app I’ve ever used!

Some sort of issue

I’ve been using this app for years now and recently I’ve been having to put code after code after code in, and every time I ask for a code it only comes after I have closed the app, and then when I open it back up to put the code in, it says expired. This app literally shows me my money earned I’d expect it to let me in. I’d say it’s a wifi issue only if I didn’t have full bars.

App issue

The app doesn’t do what I need it to do. And you don’t use safari.

Very reliable

Awesome App easy to use

Always fails

Always needs to verify phone even if you’ve marked to remember device. Constantly freezes, so difficult to just clock in and out

Website is OK, but the app is absolute worst

Two factor authentication never sends messages on time. Even if the messages come through, the app is always stuck on the loading screen. Everything works fine on the desktop. I cannot believe this app has a 4.8 star rating.

How this Dino stays on market !!!

I have an old account and i can not set a new password!!
