Payroll Outsourcing: How Much Can Your Company Save?

1. Payroll Processing as a Strategic Cost
Payroll processing is one of the most critical and, paradoxically, most underestimated functions in managing a Portuguese company. Every month, without exception, the company must process salaries, calculate IRS withholdings, determine Social Security contributions, manage allowances, sick leave, absences and overtime - and submit mandatory declarations within legal deadlines.
For many companies, especially SMEs, this function is handled by one or two internal technicians with specialised software. It seems like a simple, controlled solution. But when you do a rigorous assessment of all associated costs - salaries, social charges, software, training, error risk and team turnover - the real cost is often much higher than management perceives.
This is precisely why we developed the Payroll Outsourcing Simulator - an interactive tool that allows any manager to calculate, in real time, the cost difference between maintaining an internal team and outsourcing.
Market studies indicate that Portuguese SMEs underestimate the real cost of internal payroll processing by an average of 35% to 50%.
2. The Hidden Costs of Internal Payroll Processing
2.1 Salaries and Social Charges
The employer pays 23.75% Social Security on all remuneration, including the mandatory 14 monthly payments.
Example: An HR technician with an annual gross salary of €18,000 costs the company €18,000 + €4,275 SS = €22,275 in remuneration alone.
