Doing your own bookkeeping or outsourcing: what makes sense for a freelancer?

In short
Doing your own books costs 4 to 8 hours a month plus € 10 to € 30 of software, while a bookkeeper for a freelancer averages € 50 to € 150 a month and is fully deductible.
- Count your own hours: 48 hours of admin plus the returns costs some € 3,900 of non-billable time at a € 70 rate.
- Because the fee is deductible, you pay roughly two-thirds of your bookkeeper's monthly amount net.
- Towards the tax authorities you remain responsible for your returns, even when a bookkeeper files them.
- You must keep your records for 7 years, and data on real estate for 10 years, regardless of who does the bookkeeping.
Every freelancer starts with the same question: do I do my own bookkeeping or hand it over? Both choices can be defended, but the right one depends on your situation, your turnover and how you prefer to spend your hours. This article lays out the trade-off honestly, including the costs and pitfalls of both routes.
What does doing it yourself really cost?
On paper doing it yourself is cheap: accounting software costs around 10 to 30 euros per month. But the real cost is your time. Expect 4 to 8 hours per month for processing receipts and invoices, reconciling your bank account, your quarterly VAT return and, at the end of the year, your income tax return. At your hourly rate that quickly adds up to hundreds of euros of unbilled time per month.
Add to that the risk of mistakes. A missed deduction, a wrong VAT rate or a late return costs money directly, in missed refunds or in fines and tax interest. Those costs never appear on an invoice, but they are real.
What does outsourcing cost?
A bookkeeper for a freelancer costs on average between 50 and 150 euros per month, including VAT returns and the income tax return. Because your bookkeeper's fees are fully deductible, the net cost is lower than the invoice amount. At a tax burden of, say, 37 percent, a 66 euro per month bookkeeper effectively costs you about 42 euros.
In return, a good bookkeeper often partly or fully pays for itself: through deductions you would overlook, by arranging your provisional assessment properly and by preventing costly mistakes. So the comparison is rarely just software versus bookkeeper.
When is doing it yourself fine?
Doing your own books suits a simple situation: few invoices, no foreign clients, no staff and a straightforward cost structure. If you also do not mind studying the rules and genuinely keep your records up to date monthly, you can get quite far with good accounting software.
But be honest with yourself. In practice we often see the bookkeeping pile up in busy months, turning into a stressful catch-up right before the VAT deadline; it is one of the classic first-year mistakes. If that pattern sounds familiar, doing it yourself is cheaper on paper but more expensive in practice.
When is outsourcing the better choice?
Outsourcing becomes attractive once your situation gets more complex or your turnover grows. Think of foreign clients with reverse-charged VAT, investments you need to depreciate, doubts about the small businesses scheme, or simply more assignments than time. If the year-end assessment keeps surprising you, that too is a sign structure is missing.
The biggest gain is often not even in the numbers, but in peace of mind: you know your returns are filed on time and correctly, you have someone to ask questions and your evenings are no longer spent on receipts. For many freelancers that is easily worth the monthly fee.
The middle road: doing it together
It does not have to be all or nothing. A common middle form: you create your invoices and scan your receipts in an app, the bookkeeper checks, processes and files the returns. You keep control and insight, while the tax work sits with a professional. With a fixed monthly rate you also know exactly what to expect.
The trade-off in time and money
The honest comparison is not about the bookkeeper's invoice, but about your own hours and error risk. Factor in your own hourly rate and the sum tips faster than you think.
| Your situation | Logical choice |
|---|---|
| Few invoices, simple costs, discipline | Do it yourself with good software |
| Reverse charges, foreign clients or staff | Outsource |
| A full diary of billable hours | Outsource; your hours are worth more |
| Structurally behind on the books | Outsource before it becomes a backlog |
Worked example: 4 hours of admin a month, at a € 70 rate
- Own time: 48 hours a year plus some 8 hours of returns
- around € 3,900 in non-billable time
- Bookkeeper at a fixed monthly fee
- € 800 to € 1,500 a year, deductible
- Difference before missed deductions
- € 2,400 to € 3,100
Result: If you can make those 48 hours billable, the bookkeeper pays for themselves. If not, doing it yourself is cheaper, provided you actually keep it up
Frequently asked questions
What does doing your own books really cost?
Your software (10 to 30 euros a month) plus your own hours, usually four to eight monthly including returns. At your own rate that often exceeds outsourcing.
What do I miss doing it myself?
Mainly deductions and early warnings: the investment deduction, the right split of mixed costs, the partner allocation. One missed item quickly costs more than a year of bookkeeping.
Is there a middle way?
Yes, and it is popular: you invoice and scan receipts in the software, the bookkeeper checks quarterly and files the returns. You pay less yet keep the assurance.
Am I responsible if my bookkeeper errs?
Towards the tax authorities you remain responsible for your returns. A good bookkeeper carries professional liability insurance for damage from demonstrable errors.
When is the moment to outsource after all?
Once you structurally fall behind, VAT filing becomes tense, or things get complex through staff, foreign clients or investments. Do not wait for a backlog; see clearing a backlog.
Are outsourcing costs deductible?
Yes, fully as business costs insofar as they concern your business. Effectively you pay about two-thirds of the monthly fee net.
