Billing and Salary

The word ”ease” describes our service. You get the entrepreneur’s freedom as a light entrepreneur without the heavy administration that goes with establishing your own company. We save your repeated billings while saving you from some unnecessary repetitions of admin work. Invoicing made simple!

Our service charge is 3,9% and includes all the paperwork that the billing and payroll statutory require. If you feel that your invoicing requires a smaller percentage, don’t hesitate to discuss with our customer service. No hidden costs from salary certificates or other paperwork, all costs are included in our service fee. You will only pay the service fee when we pay your salary.

Also ask about the benefits for “high-rollers” – the service fee is a maximum of 89 euros per month.

For example: from billing of 3500 euros per month, you will only pay a 1,78% service fee. You only pay the service fee when we pay you salary, so this this is not a flat fee! For more information, contact our customer service via chat or mailing at

Ninjou offers you the possibility of salary advance when you are billing a company. Our service charge is 7,5% on advances up to 2000 euros. Advances of over 2000 euros are granted on a case-by-case basis. All advance payments are affected by the payment history of the customer company and their credit information. If your client is an individual, salary advance is not possible. Your personal credit history does not affect the granting of salary advances. Ninjou reserves the right to deny payments of salary advance if the paying company’s economical status weakens. Find out more about our advance salary best practices.

When you work with Ninjou, you are eligible for YEL Insurance which gives a level of pension to choose from. We can take out insurance for you or you can take it independently from an insurance company of your choice. We will advice you on how to get the best out of entrepreneurs’ social security services.

Ninjou cannot comment on your individual case. In general, the billing service users are often considered as entrepreneurs. Entrepreneurship affects KELA support if you are considered to be completely self-employed. Those who work under 18 hours per week as an entrepreneur are often considered as part-time entrepreneurs, which means that part of the unemployment benefits could be obtained.

However, employment officials make the final decisions for individual cases. Always check directly with them, if your situation is unsure.

Ninjou needs your tax card, if we are to pay salary to you. We primarily receive the tax cards via the users’ own pages.

Preferred format for the tax card is PDF file from the Finnish tax administration or a good quality cropped image of the printed version of your tax card. You can also order a copy to be sent to us directly from the tax officials website, The service is free.

Costs that are clearly related to the profession and cannot be considered as normal living can reduce the cost of billing easily. You can take a picture of the receipt and send it to us via your own pages, just like you would send a bill.

Receipts from accommodation and travel tickets are completely tax-free even if included and not separated in the invoice. Travel expenses that are included in the billing can be paid without withholding the tax when paying with the salary, but are reported to the tax administration as taxable earnings. This means that when the tax proposal arrives in the spring, one can apply for these expenses as tax-free.

You can also bill the kilometre reimbursements and daily allowances from the customer by specifying them on the invoice so they can be paid totally tax-free and do not have to be tax-exempted in the tax proposal.

Invoices are sent out on weekdays between 9 AM and 4 PM.

When you decide, we will send a note of the bill to the customer. Ultimately, we can together use more robust ways to complete the billing process.

Hankimme keikkatöihin tekijöitä, jotka laskuttivat Ninjoun kautta. Keikkojen laskutus sujui ripeästi ja vaivatta helppokäyttöisen alustan ansiosta. Asiakaspalvelussa oli paikoin ruuhkaa mutta muutoin meni hyvin.
