Everyone tells you to "just get a bookkeeper" once you start a business in the Netherlands, but what does a bookkeeper actually do all day? For a lot of founders, especially if you're new to the Dutch system, that stays vague: are they the person who processes your receipts, the one who files your tax return, or both? That vagueness makes it hard to know whether you need one, and what you'd actually be paying for.
At a glance: what a bookkeeper handles
| Task | Who usually does it |
|---|---|
| Processing incoming and outgoing invoices | Bookkeeper |
| Filing VAT returns (btw-aangifte) | Bookkeeper |
| Preparing annual accounts (balance sheet, profit & loss) | Bookkeeper |
| Preparing your income tax return | Bookkeeper |
| Financial and tax advice | Bookkeeper (depending on your package) |
| Business decisions | You |
| Sending invoices to your own clients | You, or outsourced as a separate service |
What a bookkeeper does in practice
A bookkeeper keeps your financial records in order and makes sure they match what the Belastingdienst (Dutch tax authority) expects. In practice, that breaks down into a handful of recurring tasks.
Processing invoices and receipts. Every invoice in and out gets booked: who bought or sold what, for how much, and under which VAT category. This is the foundation everything else builds on.
VAT returns. Most self-employed founders file omzetbelasting (VAT) every quarter. A bookkeeper totals the VAT you charged clients against the VAT you paid on business expenses, and files the balance on time.
Annual accounts. At the end of the financial year, your balance sheet and profit-and-loss statement get put together: what you own and owe, against what you earned and spent.
Income tax return. The profit from your annual accounts forms the basis for your income tax return, including the deductions you're entitled to as an entrepreneur.
Advice. Some bookkeepers, especially with a fixed monthly fee, also think ahead with you: when it's smart to time an investment, which legal structure fits your revenue, and which deduction you might be missing.
What a bookkeeper doesn't do
A bookkeeper isn't the same as an accountant (accountant, in the Dutch sense). An accountant audits and certifies annual accounts, which is mostly a requirement for larger BVs, not something a sole proprietorship deals with in practice. A bookkeeper also isn't a lawyer: drafting contracts or handling employment disputes falls outside their scope. And while a good bookkeeper will think alongside you, the actual decision, investing, hiring, switching to a BV, stays with you as the entrepreneur.
When do you actually need one?
Some founders manage their own books just fine in year one, with a handful of invoices a month and a simple setup. That usually changes once:
- Your revenue and invoice volume grow, and bookkeeping starts costing more time than you want to give it.
- You're unsure whether you're missing deductions, or uncertain what counts as a business expense.
- You've had a correction or additional assessment from the Belastingdienst.
- You'd rather spend your time on clients and projects than on your books.
An example: one month for a typical founder
Take a service-based founder with around 12 invoices a month and 20 business expenses (software, travel, office supplies). A bookkeeper processes those 32 line items, matches them to the right VAT category, and tracks what's owed at quarter-end. For an experienced bookkeeper, that's a few hours of work a month, versus 8 to 10 hours if you're figuring it out yourself, especially while you're still learning which VAT rate applies where.
Frequently asked questions
Can I handle my own bookkeeping without a bookkeeper? Yes, that's allowed. Dutch law doesn't require you to hire a bookkeeper, only to keep accurate, verifiable records. Whether you can manage that yourself depends on your time, transaction volume, and how confident you are with VAT and deduction rules.
What does a bookkeeper cost for a founder? That varies a lot by package and provider, from one-off help with a filing to a fixed monthly fee for full bookkeeping. Check our pricing for a concrete picture.
Does a bookkeeper also send invoices to my clients? That's usually not a standard task, though some bookkeepers offer it as an add-on. Ask during intake so you know exactly what's included.
Is a bookkeeper mandatory if I have a BV? Not legally required, but a BV adds tasks like payroll administration and corporate tax, which is why most BV owners outsource it.
