When employees think about payroll, they rarely notice it when everything works. They notice when it doesn't. A delayed paycheck, an inaccurate salary payment, or a payroll-related compliance issue can quickly damage employee trust and create costly consequences for employers.
This is where the benefits of payroll services come into focus. As payroll management becomes more complex, businesses are increasingly relying on specialized providers to ensure accuracy, maintain compliance, and support operational efficiency. This article examines the challenges of modern payroll management and the advantages of outsourcing payroll.
- Despite growing investment in payroll technology, 19% of organizations still rely heavily on manual payroll workflows
- Payroll complexity goes far beyond salary calculations, with errors costing employers an average of US$647 per employee each year
- Outsourced payroll services can help organizations reduce administrative workloads, strengthen compliance, and enhance employee satisfaction
Why are so many businesses still relying on manual processes?
Payroll has evolved significantly in recent years as organizations rethink how payroll processing is managed. According to ADP's Global Payroll Survey, 72% of employers are reviewing how payroll can be run with fewer people, while 44% are considering artificial intelligence (AI) as part of that transformation. At the same time, employers are increasingly looking for payroll capabilities that extend beyond traditional administration, including expertise in IT, data security, and analytics.
But there is one problem. The skills needed to modernize payroll are in short supply.
Digital transformation is only as effective as the people behind it, which is why talent shortages have become a challenge not only for payroll functions but for organizations across industries. As companies invest in modernization, many continue to struggle to secure the skills required to support these initiatives. In fact, data from ManpowerGroup's Talent Shortage survey shows that 77% of employers report difficulty finding the skilled talent they need, with IT and data-related skills among the hardest to source.
As a result, manual payroll isn't going away, with 19% of organizations reported to continue and depend heavily on manual workflows (SRR 2026).
Why are businesses reconsidering in-house payroll?
1. Payroll demands more time than many leaders realize
Payroll is often perceived as a straightforward administrative task centered on applying formulas in a salary spreadsheet. In practice, however, a single payroll cycle can involve a complex sequence of activities, varying from collecting attendance records to processing statutory deductions and generating payslips.
Ultimately, the amount of time involved often depends on two key factors:
Company size: less employees doesn't always mean less work
At first glance, it may seem logical to assume that larger organizations spend more time on payroll because they have more employees. However, the reality is often the opposite with research conducted by Gitnux suggesting that smaller organizations frequently spend more time processing payroll than larger enterprises.
| Organization Size | Days Spent per Payroll Cycle |
|---|---|
| Small businesses (<50 employees) | 5.6 |
| Medium businesses (<500 employees) | 4.1 |
| Large enterprises | 3.2 |
Industry complexity matters
Payroll complexity is not determined by headcount alone. In many industries, the nature of the workforce can make payroll significantly more time intensive.
Manufacturing is a good example. As one of Vietnam's largest employment sectors, manufacturing often relies on shift-based operations to meet production demands. A factory may run around the clock, with employees working across:
- Day shifts
- Night shifts
- Weekend shifts
- Public holidays
- Overtime schedules
While this helps maintain productivity, it can significantly increase payroll complexity.
Under Vietnam's Labor Code, employees must be compensated differently depending on when the work is performed. What may seem like a simple overtime calculation can quickly become more complex when night shifts, weekends, and public holidays are involved.
Consider the different compensation rates payroll teams must account for:
| Work Scenario | Minimum Compensation Rate |
|---|---|
| Overtime on a regular working day | 150% of normal wage |
| Overtime on a weekly rest day | 200% of normal wage |
| Overtime on a public holiday | 300% of normal wage |
| Overtime on a weekday night shift | Up to 200% of normal wage |
| Overtime on a weekend night shift | Up to 270% of normal wage |
| Overtime on a public holiday night shift | Up to 390% of normal wage |
Not to mention how workforce policies may vary from one organization to another. Even a seemingly minor change, such as redefining the start of a night shift from 11:00 PM to 10:00 PM, can affect a large number of employee records and significantly alter payroll calculations, further highlighting the complexity of payroll management.
2. The hidden costs of in-house payroll
While outsourcing is sometimes perceived as expensive, this belief doesn't always reflect reality. Studies of PwC show that around 19% of businesses cite cost as a primary concern when considering payroll outsourcing. However, this view often focuses only on service fees and overlooks the hidden costs of managing payroll in-house.
Payroll errors can be expensive
Even with experienced payroll teams, mistakes happen. According to EY, organizations achieve an average payroll accuracy rate of 80.15%, meaning payroll errors remain a common challenge. More importantly, each payroll error costs businesses an average of US$291 to resolve when direct and indirect costs are taken into account.
Some of the most common issues include:
- Time/attendance and expense errors: More than once per employee per year.
- Vacation/paid time off/sick time request errors: 721 errors per 1,000 employees
- Benefit errors: 503 error per 1,000 employees
Taken together, these errors cost employers an average of US$647 per employee annually to correct. And that's before accounting for the potential impact on employee trust and productivity.
Compliance is a moving target
Payroll compliance is not a one-time exercise. In Vietnam, businesses must navigate a regulatory environment where labor, tax, and social insurance requirements are regularly updated.
In 2025 alone, employers had to keep pace with numerous compliance requirements across payroll, taxation, insurance, and employment regulations. Staying aligned with these changes requires both expertise and continuous monitoring. And if businesses don't have the resources or expertise to keep up? The costs can add up quickly in the form of back-pay obligations, interest charges, and financial penalties.
Take social insurance as an example. Under Vietnam's current social insurance framework, employers that incorrectly calculate, underreport, or fail to make mandatory social insurance contributions may be required to repay outstanding amounts and face penalties of up to VND 10 million.

Payroll accuracy affects employee experience
Getting payroll right is not only a compliance issue, it is also an employee experience issue.
In a labor market where skilled talent remains difficult to find, even small payroll mistakes can have an outsized impact. According to WorldMetrics, 92% of employees report higher job satisfaction when they are paid accurately and on time.
Employees may not notice a flawless payroll process, but they will almost certainly notice an incorrect paycheck, delayed payment, or missing allowance. Over time, these issues can undermine trust and create unnecessary friction in the employee experience.
How payroll services save time and cost
While every business has different requirements, the differences between in-house payroll and payroll services are often most visible in the areas below.
| Challenge | In-house payroll | Payroll outsourcing |
|---|---|---|
| Time-intensive payroll processing | HR and finance teams may spend days each payroll cycle collecting attendance data, calculating salaries, processing deductions, and generating payslips. |
Dedicated payroll specialists and streamlined processes help reduce administrative workloads and free up time for higher-value priorities. |
| Complex workforce and changing compliance requirements |
Overtime, shift premiums, bonuses, PIT, and mandatory insurance contributions require ongoing calculations and manual checks. |
Experienced payroll professionals manage complex payroll requirements using established processes and payroll systems. |
| Payroll errors |
Manual calculations and administrative workloads can increase the likelihood of payroll errors, resulting in correction costs and productivity loss. |
Standardized processes help improve payroll accuracy and reduce the time spent resolving payroll issues. |
| Employee experience |
Incorrect pay, delayed payments, or payroll discrepancies can impact employee trust and satisfaction. |
Accurate and timely payroll processing helps create a more consistent employee experience. |
That said, outsourced payroll services are not without their challenges. Some businesses may have concerns around data security, responsiveness, or visibility into payroll operations. Others may be hesitant to entrust a third party with a function that directly impacts employees.
