Why organisations outsource their payroll administration

Payroll ranks among the most exacting tasks any organisation handles. Each month, people need to be paid the right amount at the right time, the payroll tax return has to go in to the tax authorities, and everything has to hold up against current legislation. This work calls for specialist knowledge, real accuracy and a close eye on shifting collective agreements, tax rules and social security law. It's easy to see why so many organisations now leave their payroll administration to a specialist. This article explains what outsourcing payroll administration involves, where the advantages lie, which options exist and what deserves your attention.

What does outsourcing payroll administration involve? 

When you outsource payroll administration, a specialist external partner takes over your monthly salary processing. That covers calculating gross and net salaries, handling changes such as new starters, leavers and role changes, filing the payroll tax return with the tax authorities and providing pension overviews.

This is different from an arrangement where an external company also becomes the legal employer (sometimes called "payrolling" or "employer-of-record"). With payroll outsourcing, you stay the employer and only hand over the administrative side. The level of outsourcing is your choice. Some organisations outsource only the salary processing and keep everything else internal. Others prefer a broader arrangement, where the partner also advises on changes to collective agreements, tax schemes and employment-law matters.

Payroll administration: in-house or outsourced?

Every organisation wants its payroll administration running smoothly. The question is which route gets you there. Doing it yourself looks cheaper at first glance, though the true cost often runs higher than expected. Just think of the hours HR or finance teams lose to processing changes and fixing errors. Research by Remote shows the average HR department in the Netherlands spends three to six days a month on payroll administration. That's valuable time lost to work that could be going into strategic HR instead.

The picture on the ground is clear, with more and more organisations making the move to outsourcing their payroll. As many as 82.5% of Dutch HR managers have considered outsourcing their payroll administration. Worldwide, 73% of organisations now outsource at least one payroll activity, according to Deloitte, and in Europe the figure sits at 61%. The trend leaves little doubt: outsourcing payroll administration is fast becoming the norm.

 

The benefits of outsourcing payroll administration

Organisations come to outsourcing for all sorts of reasons. Whatever prompts the decision, the goal tends to be the same: reliable payroll that runs efficiently. Outsourcing brings several concrete benefits along the way. Here are the most important ones.

Less risk of errors and fines

A specialist external partner works with proven processes, automated validations and current knowledge of tax obligations, which makes errors far less likely. That's worth a great deal, given that mistakes in the payroll tax return or a late filing can trigger serious penalties from the tax authorities.

Software tip! Payroll software automates the key parts of payroll administration and brings mistakes to an absolute minimum. 

Cost savings and predictable spending

Outsourcing is an investment, though the overall cost frequently comes in under the in-house alternative. Weigh up the salaries of the people running payroll internally, the price of payroll software and licences, and the hidden cost of errors and corrections. Outsourcing also tends to run on a fixed rate per employee per month, which keeps spending clear and easy to forecast.

More time for strategic work

Salary processing is time-consuming and repetitive. Outsourcing it frees up lasting time for the HR work that really matters: employee engagement, talent development, strategic workforce planning and organisational development. In organisations with a lean HR team, the gain is especially welcome.

Continuity through illness and staff changes

When payroll is kept in-house, the knowledge usually lives with one or two people. The moment one of them falls ill, moves on or can't keep up with the workload, everything comes under pressure. An external specialist team keeps things steady, whatever the season and whatever comes up.

Always up to date with the law

New rules and adjustments appear all the time. A specialist payroll partner tracks them closely and applies each change to your payroll automatically, as soon as it comes into force. There's no need to keep up with any of it yourself, and outdated knowledge won't lead you into costly mistakes.

In summary, these are the key benefits of outsourcing your payroll administration:

  • Fewer errors: specialised payroll experts ensure accurate and reliable payroll processing.
  • Better cost control: you save time and reduce costs, while fixed fees make your expenses more predictable.
  • More time for strategic HR: with administrative tasks taken care of, you have more time to focus on your people and organisation.
  • Greater continuity: with a team of experts supporting you, payroll processing continues smoothly, even during illness, holidays or staff turnover.
  • Always up-to-date expertise: a specialised partner keeps track of changes in collective labour agreements, legislation and regulations.

 

What are the different ways to outsource payroll?

Payroll administration can be outsourced in several ways. Which form suits you best comes down to the size of your organisation, the in-house knowledge you have and how much you want taken off your hands.

Full outsourcing

With full outsourcing, the entire payroll administration goes to an external payroll partner, covering the complete salary processing, the payroll tax return, the pension filings and any updates to collective agreements. You provide the input, and the partner looks after everything else. This model offers maximum support and appeals in particular to organisations without payroll expertise of their own.

Partial outsourcing (co-sourcing)

Partial outsourcing entails keeping certain payroll administrative functions in-house, but outsourcing some tasks or more complex elements to an external partner. You could outsource the payroll tax return and the processing of collective agreements, for instance, but keep the day-to-day changes in-house. This model mixes internal involvement and external expertise.

Doing it yourself, with expert support on hand

A third option is to run payroll on specialist software, staying in charge yourself while drawing on the software provider's expertise whenever you need it. You handle the day-to-day payroll work, with payroll specialists on call for the trickier questions. This suits organisations that want to keep control, yet don't have, or don't want to build, all the payroll knowledge in-house.

What to look for in a payroll partner?

Outsourcing payroll administration isn't only an operational decision. You're placing a vital part of your organisation in someone else's hands. Choosing the right partner comes down to a handful of key factors, set out below.

1. Deep payroll expertise

Go for a partner with proven knowledge of legislation, collective agreements and tax obligations. Ask about the team's experience and how they keep up with the annual changes to the law.

2. Integration options

A strong payroll partner links up neatly with your existing HR system, time tracking and other relevant tools. Data flows reliably between systems, with no more double entry.

3. Transparent service levels

Find out which tasks sit with the partner and which stay with you. Clear agreements on responsibilities, turnaround times and points of contact head off misunderstandings and make for a smooth partnership.

4. Personal contact and support

Payroll sometimes calls for fast action, an urgent correction or a tricky situation that can't wait. Pick a partner who's easy to reach and gives you a dedicated contact who knows your organisation.

5. GDPR compiance and data security

Check that the partner demonstrably meets GDPR requirements. Ask about their security measures, how personal data is stored and deleted, and put a data processing agreement in place.

6. Scalability

As your organisation grows, so does the complexity of your payroll. Choose an external payroll partner that scales with you easily, without you having to hire extra staff or overhaul your internal processes.
