    You know who signs.

  • Agents do the routine work

    A person checks every figure against the official source.

November is the tight month: payroll and two VAT payments land before the December invoices are paid. Cash stays above €90k on current terms.

Example with a made-up group. Your page shows your own companies. Until the live page is ready, your accountant sends you this view at the start of every month. The cash and 90-day view comes with monthly management accounts (Growth plan, One Group Close for groups, or the Finance Team service).

Before we talk.

Can you help in the countries involved?

Tell us the countries and the work you need. We confirm availability before you commit, including any local professional required. A skill covering a country does not mean every service is available there.

Who will handle my work?

Your written engagement with OpenAccountants names the accountant responsible and their scope. Writing or checking a skill does not automatically assign that accountant to your enquiry.

How does pricing work?

Published prices apply to the services, limits and markets listed. Large multinational groups are quoted individually. Separately quoted work is marked in the price list; other unlisted accounting work uses our published hourly rate. Your written engagement records the services you select, the total fee and the accountant responsible. The introductory call is free; any other free introductory work is stated in the relevant offer.

What if I already have an accountant?

Tell us what your current accountant handles and the work you want us to take on. We agree the scope and any handover before starting.

Can I use the free tools without becoming a client?

Yes. Our skills and AI connection are free to use. They help with research and drafts; using them does not create an accounting engagement or submit a filing.
