Compare the three payroll models: in-house team, SaaS software and full outsourcing. Criteria on cost, control, compliance risk and the right moment for each one.
Translated from Romanian. This article covers Romanian labour and tax law; the Romanian version is canonical and is updated first.
Almost every company reaches the same question at some point: do we keep payroll in-house, buy software, or hand it over entirely to somebody else? There is no universal answer — there is an answer that suits your size, your complexity and your tolerance for risk. Here is how to choose with your eyes open.
1. In-house, on your own. Someone inside the company (an in-house accountant or an HR lead) calculates the payroll, using an accounting program and, often, a spreadsheet alongside it.
2. Software (SaaS). The company uses a platform that automates the calculation and the workflows, but the decisions and the control stay in-house. The accountant finalises and files the declarations.
3. Managed service / outsourcing (BPO). An external provider takes over the process: it receives the data, calculates, produces the documents and, as a rule, handles the reporting as well. The company remains legally responsible, but operationally it offloads the work.
The three are not compulsory successive stages. Many companies stay healthily on model 2 for years.
Comparing on “price per employee” is misleading. The real cost of the in-house option includes:
The last point is the most underestimated. In a small company, payroll often depends on a single person who knows “how it is done”. That is an operational vulnerability, not a saving.
The essential difference between SaaS and full outsourcing is not the price, but who owns the process:
| Software (SaaS) | Managed service | |
|---|---|---|
| Who calculates | the company, assisted by the system | the provider |
| Speed of a correction | immediate, you do it yourself | depends on the provider |
| Visibility over the data | complete, in real time | through reports |
| Dependence on the provider | medium (the data stays with you) | high |
| Cost as you grow | scales per employee | scales per employee plus complexity |
If you need to answer “why is X’s net pay lower this month?” quickly, the option in which you have the data at hand is clearly superior.
An important clarification: legal liability stays with the employer. You can outsource the execution, not the obligation. If the provider gets a declaration wrong, the authority turns to the company, not to the provider. The contract gives you a right of recourse, but it does not remove you from the position of the responsible party.
That is why, whatever the model, you must keep:
The question to ask before signing: if we terminate tomorrow, in what format do I get the history, and how long does it take?
In-house, with software — suitable for most small and medium companies. You have control, predictable costs, and the automation covers the repetitive part. It only becomes difficult if you have very complex salary structures or operations in several countries.
Full outsourcing — makes sense when: you do not have and do not want in-house payroll expertise; you have high turnover that makes it impossible for anyone to specialise; or you operate in several jurisdictions and need someone who covers them all.
A hybrid model — the most common in practice: software in-house for time tracking, leave and the ongoing calculation, plus an accountant (internal or external) who validates and files the declarations. It combines control with expertise.
Does outsourcing payroll release me from liability? No. You can outsource the execution, but legal liability towards the authorities stays with the employer. The contract governs compensation, not responsibility.
Which is cheaper — software or outsourcing? It depends on size and complexity. Software has a predictable cost and better control; outsourcing reduces the need for in-house expertise, but costs more per employee and adds dependence.
What happens to my data if I change provider? This is the key question to ask before signing. Ask explicitly for the export format and the deadline for delivering the history when the contract ends.
Can I combine the two? Yes, and it is the most common workable model: an in-house platform for time tracking, leave and calculation, plus an accountant for validation and filing the declarations.

Workly is built for the model that works best in most Romanian small and medium companies: the process stays with you, the repetitive work disappears. Time tracking, leave and the salary calculation flow from a single data source, and the result is exported in SAGA format to your accountant — internal or external — who validates and files the declarations.
In practice, you keep control and visibility (you can see at any time where every figure comes from, with a history of changes), but you no longer pay for human time spent on transcription and reconciliation. And the dependence on a single person disappears: the process lives in the platform, not in someone’s head. The data belongs to you and can be exported at any time — the condition you should demand from any provider, whatever the model.
