Will outsourcing payroll processing to a payroll service provider make sense for your business or should you continue to own the payroll service process in-house?
Comparing the cost payroll outsourcing vs. the Total Cost of Ownership (TCO) of payroll can be tricky to work out especially in an international or regional enterprise situation. As such, Links regularly help clients to review their existing payroll landscape and also work out several business cases, so as to decide if outsourcing or inhousing payroll makes more financial sense.
Here are some of the key points to consider when building the business case(s):
- Payroll engines, platforms or systems needed to process or run the payroll
- Payroll resource required to process or run the payroll engines, platforms and systems
- Include benefits provided to the payroll resource, such as base salary, bonuses, social insurance, provident fund or pension, leaves benefits, training, related support
- Other overheads including maintenance, updates, upgrades, laptops, office space, other related tools
- Replacement costs in event of attrition or termination of agreements
- Future proofing system and operation landscape
Here are some of the key considerations, or benefits, for payroll outsourced firms:
| Benefits | Translated to business wins |
| Efficiency | Specialist teams + streamlined process means great response times, better business partnering and more value added support by the HR teams to business units |
| Key man dependencies | Reduced risks of dependencies without business contingency plans or continuity plan, as well as reduced human errors or possibilities of non-compliances |
| Employee experiences | Enhance employee experiences with on-the-go access to self-service via mobile, single sign-on and other automations |
| Data security and compliance | Improved data security and hosting infrastructure, coupled with ISO 27001 industry best practices to eliminate data leakage |
| Future proofing | Future proof system landscape for a robust, sustainable and scalable paytech operating model that offers centralised governance, control with in-country compliance and last mile localisation, especially with SAP SuccessFactors, Workday, Oracle and more |
| Scalability | Easier to support business growth, multiple locations, acquisitions, or international employees without the need to hire additional payroll staffs as headcount grows |

Who needs to be involved in building the business case:
Based on our experience, the strongest business cases comes with cross-functional input, such as from HR, Payroll teams, Finance, IT, Operations, and even Legal to support a fuller picture of the current payroll landscape + status within the company. This includes the accompanying tangible and intangible risks, implications and concerns from all key pillars of the organisation.
So what needs to be included in the business case:
| Section | What to include |
| Executive summary | Current pain points (e.g. fragmented technology, lack of governance); strategic goals such as improved data security, compliance, scalability, and user experience |
| TCO analysis | Hard costs: current and future technology and labour spend · Soft costs: savings from cost avoidance and reduction |
| Deployment strategy | Rollout order factoring in region, time zone, language, and contract expiry dates |
| Risk assessment | Common concerns include data security, staff impact and go-live disruption – for each, outline your mitigation plan (i.e. ISO 27001-certified provider, phased rollout with parallel payroll runs) |
| Stakeholder alignment | Tailor your pitch by audience: Finance wants ROI, HR wants compliance and employee experience, IT wants integration and data security |
| Measures of success | Define KPIs upfront: payroll error rates, compliance audit results, cost savings year-on-year, and reduction in monthly admin hours |
While a well structured business case certainly facilities the kicking off of this discussion overall, it is necessary to still keep the presentation of this case a concise one, with easily identifiable, measurable, actionable steps with a timeline. Materials to record, consolidate, summarise, track and socialise to the respective stakeholders and business units, with cadence meetings set after this presentation must also be executed to complete the process.
