GuidesAccountant for limited companies (Oy)
Accountant for limited companies (Oy)
A limited company’s finance work is usually broader than a sole trader’s: monthly bookkeeping, year-end, possible payroll, and admin support. The right firm keeps the whole picture under control and reporting understandable.
What does an Oy typically need?
Needs vary by size, but most limited companies need at least:
- Monthly bookkeeping and VAT returns
- Annual accounts and corporate tax filings
- Payroll if there are employees (including owner salary)
- Reporting — profit, cash, and key figures when useful
- Advice on topics like dividends, investments, or financing
Year-end is not a side note
Oy annual accounts are statutory and take time. Always ask whether they are included in the monthly fee or billed separately, and on what timeline. Compare offers on a yearly basis.
Growth and payroll
As headcount grows or operations diversify, you often need clearer ownership and faster reporting. Mention growth plans in the enquiry so capacity is assessed correctly.
Indicative price ranges for an Oy
Conservative, typical estimates excluding VAT. Actual offers depend on volume, payroll, and scope.
Small Oy, moderate volume, no payroll
More in complex cases.
- often about €100–300 / month
Oy with payroll
Or an agreed package; special pay raises the price.
- monthly fee + about €10–25 / employee / month
Annual accounts and tax return, small Oy
More in complex situations.
- often about €300–800 / year
Ask a limited-company firm
- What is in the monthly fee versus the year-end fee?
- How is payroll priced (per employee or as a package)?
- Who is practically responsible for filings and signing them?
- What reports do I get each month?
- Do you have experience in my industry or similar size?
- How does communication work under pressure (for example lender requests)?
Frequently asked questions
Is Oy bookkeeping very different from a sole trader?+
Usually yes. Year-end, admin, and possible payroll add work, so the monthly fee is often higher.
Must the firm be local?+
Not necessarily. Many Oys use remote service. Local can help if you want meetings — state your preference in the enquiry.
How should I compare Oy offers?+
Compute first-year total cost: monthly fees, year-end, payroll, software, and expected extras. Compare the same scope.
Can an Oy switch firms mid-year?+
Yes. Read the switching guide and agree data handover and filing responsibility in writing.
