B2B vs employment — key differences

B2B vs employment is one of the most common comparisons on the job market. B2B often gives more flexibility and potentially higher net pay, but it does not provide labour‑code protection. An employment contract offers stability, paid leave and notice rules, but it also means higher total cost for the employer. Below you will find the differences, costs and risks so you can make a realistic decision for your situation.

B2B and employment — basic differences

Legal status and protection

An employment contract creates a labour relationship regulated by the Labour Code. That means protection in certain dismissal situations, working‑time rules and employer contributions. B2B is a civil contract — the rules are defined in the agreement, and labour‑code protection generally does not apply.

Paid leave, sick pay and liability

On employment you have statutory paid leave and sick pay. In B2B, paid leave or sick pay depends on contract clauses or private insurance. B2B also means greater responsibility for results and potential contractual penalties.

Working time and subordination

Employment is regulated by labour‑code rules on working time and supervision. In B2B, flexibility is an advantage, but if cooperation looks like employment in practice (fixed hours, subordination, one workplace), the risk of reclassification increases.

Employer cost and worker net pay

Contributions and taxes in brief

With employment, contributions are shared between employer and employee. In B2B, contributions and tax are on the contractor side (sole proprietorship or company) and depend on the tax form and contribution base. See B2B taxes and B2B ZUS contributions.

Brutto‑brutto vs invoice

For employment, the “total company cost” includes gross salary plus employer contributions. In B2B, the cost is the invoice amount (often + VAT), while the contractor bears contributions, tax and business overhead (accounting, insurance, equipment). Comparing only gross pay can be misleading.

A quick comparison example

With the same “total cost for the company” B2B often leaves more net pay, but the difference depends on taxes and contributions. The quickest way is to compare in the B2B calculator and then cross‑check with employment or mandate contract. For more context see Mandate vs employment.

Risks and pitfalls

Pseudo‑B2B and inspections

If B2B in practice looks like employment (fixed hours, subordination, workplace), ZUS or the tax office may reclassify the contract. This can lead to additional contributions and tax arrears. This is one of the main risks to consider.

Contract penalties and lack of protection

B2B contracts often include penalties, non‑compete clauses and broader liability. With employment some risks are limited by law. In B2B it is crucial to review the contract scope and liability.

When B2B makes sense

Conditions for profitability

B2B usually makes sense when the invoice rate is clearly higher than the employment cost and the contractor accepts the lack of paid leave and protection. In practice, the key factors are costs, tax form and contributions.

How to calculate the difference

Use real numbers and compare scenarios. The B2B calculator and the guide When B2B pays off help you assess net pay and risk.

When employment may be a better choice

Employment can be preferable when you need stability, legal protection and predictable benefits. This is common when:

• the invoice rate does not compensate for no paid leave or sick pay,
• the client expects full subordination and fixed hours,
• you want protection in case of termination or illness,
• you do not want contract‑level liability and penalties.

A quick decision checklist

Before you decide, answer these questions with real numbers:

• Is your invoice rate at least a clear premium over the employment total cost?
• Do you have a buffer for unpaid leave, sickness and gaps between projects?
• Are you prepared to handle accounting, taxes and reporting on your own?
• Does the contract limit liability and clearly define scope and IP ownership?

If any answer is “no”, employment may be safer even if B2B looks slightly higher on paper.

What to include in a like‑for‑like comparison

To compare fairly, align:

• total cost for the client (same budget on both options),
• working time (paid leave and holidays vs billable days),
• costs on B2B (accounting, insurance, tools),
• protection value (notice period, sick pay, severance).

Only after these adjustments does the net comparison show real profitability.

Non‑financial factors

Beyond net pay, consider stability, benefits, and career preferences. Some people value flexibility and autonomy, while others prefer predictable income and employer‑provided benefits. If the difference is small, choose the form that fits your long‑term priorities rather than optimizing for short‑term net.

Setup and administration

B2B also means setting up a business, invoicing, and ongoing administration. If you prefer minimal paperwork, employment can be less burdensome. If you are comfortable with admin work or outsource accounting, B2B becomes easier to sustain.
