Nobody switches payroll platforms for fun. You switch when the workarounds become the job.
Most of our UKG Ready clients didn't start with us. They started with a big national provider, usually ADP, and it worked fine until it didn't. The workforce got more complex, the add-ons piled up, and payroll week turned into firefighting. I've sat across the table from enough of these teams to know the pattern by heart. Here are the nine signs your current setup no longer fits, what staying put actually costs, and what a switch really looks like when you do it right.
The Short Answer
ADP and UKG Ready are both mature HCM platforms. The difference that matters for mid-market companies: ADP's portfolio often means multiple products stitched together, while UKG Ready runs HR, time, scheduling, and payroll on one database. If you're reconciling data between systems, fighting fires every payroll week, and waiting in ticket queues for support, those are switching signals. A well-run migration takes 8 to 16 weeks with a partner who forces the hard decisions early.
ADP vs UKG Ready by the Numbers
- A single payroll input error costs an average of $291 to resolve (Ernst & Young).
- One in five US payrolls contains errors (Ernst & Young).
- Payroll leakage eats 2% to 4% of total labor spend (UKG and KPMG).
- 49% of workers start job hunting after two paycheck problems (The Workforce Institute).
- The IRS assessed nearly 4.5 million employment-tax penalties in FY2025 (IRS Data Book).

Why do companies outgrow their ADP setup?
Not because ADP is bad software. Because the setup that fit you at 80 employees doesn't fit at 300.
The pattern is the same every time: the company adds locations, shifts, or states. Each new need becomes another module, another add-on, another connector. Pretty soon HR, time, scheduling, and payroll live in different places, and your team becomes the integration layer, moving data by hand and praying nothing drifts.
Meanwhile support gets more generic as you need it to be more specific. You open tickets, repeat your context, and bounce between teams while a payroll deadline sits there staring at you.
None of that shows up in the original demo. All of it shows up by year three.
The 9 signs it's time to switch
- Too many moving parts: Separate products for time, scheduling, HR, and payroll, and your team spends hours reconciling them.
- Support feels generic: Ticket queues, repeated context, and no one who knows your setup by name.
- Payroll week is firefighting: Missing approvals, wrong differentials, and tax surprises that surface right before transmit.
- Reporting means exports: Leadership asks for overtime by location and the answer is a two-day spreadsheet project.
- Your workforce outgrew the build: Multi-state employees, remote teams, and variable schedules the original configuration can't handle.
- Self-service that isn't: Employees ping HR for pay stubs and PTO balances because the portal fights them.
- Compliance is reactive: You learn about rule changes when they cause exceptions instead of before.
- Every need is a new connector: New accrual rules or analytics mean another integration or services engagement.
- You've outgrown the operating model: You want a named team that answers the phone, not a ticket number.
What does staying put actually cost?
The status quo feels free because the invoice is familiar. It isn't free.
Ernst & Young's payroll research found that a single payroll input error costs an average of $291 to resolve, and one in five US payrolls contains errors. Stack that against the UKG and KPMG finding that organizations lose 2% to 4% of total labor spend to payroll leakage, and a fragmented setup is quietly one of your bigger vendors.
The people cost is worse. The Workforce Institute found 49% of workers start a new job search after just two paycheck problems. Two. In a market where you're fighting for CNAs and machine operators, your payroll accuracy is a retention program.
And the compliance backdrop keeps getting less forgiving: the IRS assessed nearly 4.5 million employment-tax penalties in FY2025, and the DOL recovered more than $259 million in back wages the same year.

Get My NumbersWhat does switching actually look like?
Shorter and less dramatic than the horror stories, if you run it right.
Mid-market UKG Ready implementations typically run 8 to 16 weeks. The sequence that works: data extraction and cleanup first, pay rules and accruals configured and tested against real history, parallel payroll runs until the outputs match to the penny, then cutover at a quarter boundary so year-to-date numbers stay clean.
What stretches timelines is never the data transfer. It's unmade decisions: who approves what, which rules are actually policy versus habit. A good partner forces those decisions in week two, not week ten.
Our payroll services team has run this migration enough times that the surprises are rarely surprises anymore.
Why switch through a partner instead of buying direct?
Same software, different experience. Buy UKG Ready through a UKG Ready Preferred Partner and implementation, training, and support come from a named team that learns your chart of accounts, your accrual rules, and your edge cases.
That matters most at exactly the moments that made you want to leave your current provider: quarter-end, year-end, and the Friday afternoon when a direct deposit bounces. You call someone who already knows your environment. That's the whole pitch, and it's why we've kept doing it this way since 2011.
Andy's take
Time your cutover to a quarter start and insist on at least two parallel payroll runs before go-live. Every migration that went sideways on someone skipped one of those two things.

Frequently Asked Questions About ADP vs UKG Ready
How long does it take to switch from ADP to UKG Ready?
Plan on 8 to 16 weeks for a mid-market company: data cleanup, configuration, parallel payroll runs, then cutover at a quarter boundary. Decisions, not data transfer, are what stretch timelines.
Is UKG Ready cheaper than ADP?
Pricing is quote-based on both sides, so nobody can promise that honestly. What changes the total cost is consolidation: one platform for HR, time, scheduling, and payroll means fewer add-on modules, fewer connectors, and fewer hours spent reconciling data.
Will we lose payroll history in the migration?
No. Historical data migrates, and a proper implementation validates year-to-date numbers with parallel runs before cutover. Timing the switch to a quarter boundary keeps tax filings clean.
What's the biggest risk in switching payroll providers?
A rushed go-live. The way to de-risk it: force configuration decisions early, test with your real pay history, and run payroll in parallel until outputs match to the penny. That's the discipline a hands-on partner enforces.
