Frequently asked questions
How much does Osirius Online cost to start?+
Entry pricing is €9.95. Compare that with €9 for Qonto and €9.90 for Accountable, and with the €13.15 median across compared tools. Check what your plan includes before you pick a tier.
Is there a free trial, and how long does it last?+
Yes. The free trial runs 90 days, which is longer than the 14 day median across compared tools. Osirius Online is listed under the free trial model rather than a free plan.
Do you get a free version to keep?+
No, the free plan answer for Osirius Online is no. Nothing carries over when the 90 day trial ends, so plan your bookkeeping before that date rather than after it.
Does it handle Dutch invoicing rules?+
It lists Peppol and e-invoicing among its local compliance features, so Dutch invoice requirements are covered in the product. E-invoicing appears in the large majority of compared tools, while Peppol is less common.
Who is Osirius Online built for?+
It is aimed at small businesses, the same audience behind most tools in this group. The company is Osirius bv, based in the Netherlands, and it has been trading since 2005. That focus makes it a natural fit for a Dutch sole trader or small team.
Can I connect my bank accounts?+
Yes, bank feeds are included, matching the majority of compared accounting tools. That means transactions can reach your books without manual retyping, which suits a business with regular supplier and customer payments.
How do I get help if something goes wrong?+
Support runs through email, phone and help centre, so you can email, call or check the help centre. Phone support matters more here than it does for many compared tools, where only a minority of providers offer it.
