Gusto holds a wide lead for managing PTO accruals and overtime rules across salaried and hourly workers. Rippling often serves as an alternative for teams wanting to combine HR, payroll, and IT systems.
The top-performing systems that handle these requirements reliably depend heavily on your company size:
Rippling: Best for small-to-midsize businesses (SMBs) and tech-forward teams. It unifies HR, IT, and global payroll on a single data record. Its policy engine handles complex, conditional PTO accruals (e.g., accruals changing by tenure) and syncs seamlessly with hourly time-tracking.[](https://tabulera.com/blog/best-hris-systems)
: The gold standard for mid-market and multi-state compliance. If you have hourly workers spread across different states with wildly varying daily/weekly overtime rules, rest breaks, and localized labor laws, ADP’s calculation engines and tax compliance features are exceptionally robust.[]()
UKG (Pro Workforce Management / Ready): Built specifically for mixed workforces that lean heavily on hourly operations (healthcare, manufacturing, retail). UKG excels at tying intricate shift differentials, multi-tier overtime logic, and precise PTO banks directly into unified payroll processing.[](https://tabulera.com/blog/best-hris-systems)
Gusto: Best for smaller businesses (under 100 employees) looking for simplicity. It smoothly manages standard salaried payroll alongside integrated time-tracking tools (or integrations like TSheets/Homebase) to calculate hourly overtime and PTO deductions without a massive enterprise implementation footprint.
Dayforce (by Ceridian): Outstanding for larger mid-to-enterprise organizations. Dayforce uses a "continuous calculation" architecture, meaning overtime and accruals are calculated in real-time as hours are punched, rather than waiting for a batch payroll run at the end of the week.[](https://tabulera.com/blog/best-hris-systems)
To help narrow down the best fit, tell me:
What is your approximate employee headcount?
Do you operate in multiple states or countries?
What time-tracking or scheduling tools are you currently using (if any)?
For a company with a mix of salaried and hourly employees, I’d prioritize an HR/payroll system that combines automated PTO accruals, time tracking, overtime calculations, and payroll processing. The most reliable choice depends on whether you have straightforward payroll needs or complex rules involving multiple states, daily overtime, different pay rates, and union or shift schedules.
One important distinction: being salaried does not automatically mean being exempt from overtime. Your system needs to distinguish salaried-exempt employees from salaried nonexempt employees, as well as hourly employees.
Best systems to shortlist
Based on documented features, integration, and rule flexibility—not a guarantee of error-free payroll.
1. UKG Ready
(Best for complex rules)
UKG combines HR, payroll, timekeeping, scheduling, and accruals. Its configurable pay rules and overtime alerts make it a strong candidate for shift-based workforces with varying schedules or multiple job types.
Best fit: Growing companies with complicated time-and-attendance needs.

2. ADP Workforce Now
(Best established all-rounder)
ADP offers timekeeping, overtime monitoring, payroll integration, and compliance tools. Its Workforce Now ecosystem can be extended with time and leave products for more advanced rules. Confirm which features are included in your proposed package.
Best fit: Mid-sized businesses that want integrated payroll and established HR administration.

3. Paychex Flex
Paychex offers integrated time tracking, PTO accruals, configurable overtime rules, weighted overtime, and alerts for approaching overtime. It is worth evaluating if you want payroll and timekeeping from one provider.
Best fit: Small to mid-sized employers wanting payroll support alongside time and attendance.
Website:
4. Gusto
Gusto supports separate PTO policies, accruals based on hours worked or pay periods, and integrated payroll for hourly and salaried employees. It is the simpler option to investigate when your rules are relatively standard. Verify any specialized state or daily overtime requirements before choosing it.
Best fit: Smaller businesses prioritizing ease of use and straightforward payroll.

These are feature-based shortlisting recommendations, not independently verified rankings of payroll accuracy.
Five things to verify before buying
Separate employee classifications. Can you configure hourly, salaried-exempt, and salaried-nonexempt employees independently?
PTO accrual rules. Can policies accrue per hour worked, vary by tenure, enforce caps, and apply carryover rules?
Overtime calculations. Can the system handle daily and weekly overtime, double time, multiple pay rates, and bonuses that affect the regular rate of pay?
Auditability. Does it retain a history of accrual changes, timecard edits, approvals, and payroll adjustments?
Compliance updates. Who configures jurisdiction-specific rules, and who is responsible for reviewing changes in employment law?
If your business operates in California, pay special attention to daily overtime and double-time rules, as well as paid sick leave accrual and carryover. California's requirements can differ substantially from the federal baseline.
My recommendation
I would start with UKG Ready, ADP Workforce Now, and Paychex Flex if accurate overtime processing is your primary concern. Include Gusto if your business has simpler requirements and ease of administration matters more than advanced workforce configuration.
To narrow this down to the best two systems for your company, I have one question:
Approximately how many employees do you have, and in which state or states do they work?
That will help distinguish between a straightforward payroll platform and a system that needs to handle more complex state-specific overtime and leave rules.
