How Much Does an In-House Bookkeeper Cost?
An in-house bookkeeper in Europe typically costs €25,000-45,000 per year in gross salary, and the true cost is 20-40% higher once you add employer social contributions, paid leave, equipment, and training. That is €2,080-4,500+ per month — a fixed commitment regardless of how many invoices arrive. For invoice-heavy bookkeeping, per-invoice AI processing from $0.40 per processed invoice scales with your actual volume instead.
| Cost component | Typical annual amount | Notes |
|---|---|---|
| Gross salary (entry-level) | €25,000-32,000 / year | Junior bookkeeper, limited experience. Common in GR, Eastern EU. |
| Gross salary (experienced) | €32,000-45,000 / year | Senior bookkeeper who can also handle reconciliations and reporting. |
| Employer social contributions | +20-40% of salary | Varies by country. Greece ~22%, Ukraine ~22%, Western EU higher. |
| Paid leave & holidays | ~1 month of productivity | Bookkeeper is absent ~4-6 weeks/year but salary continues. |
| Equipment, software, training | €1,000-3,000 / year | Laptop, accounting software licence, onboarding. |
How Nika compares
An in-house bookkeeper is a fixed monthly cost of €2,080-4,500+ whether you process 50 invoices or 500. Nika charges $0.40 per processed invoice — so a month with 200 invoices costs a fraction of a salary, and a quiet month costs even less. There is no hiring process, no onboarding, no paid leave, and no equipment to buy.
Verdict
Hiring an in-house bookkeeper makes sense when transaction volume is consistently high enough to justify a full-time salary, and when you need someone physically present for cash handling, supplier relationships, or complex accounting. If the core need is reliable invoice filing, an in-house salary is the most expensive way to get it. Per-invoice AI pricing plus an external accountant for review is typically far cheaper.
Questions
What is the fully loaded cost of an in-house bookkeeper?
Salary plus employer contributions, paid leave, equipment, and training. A €30,000 gross salary typically becomes €36,000-42,000 all-in — roughly €3,000-3,500 per month — before any productivity loss from holidays or sick leave.
When does an in-house bookkeeper become cheaper than AI?
Only at very high, consistent invoice volumes — typically above 1,000-1,500 invoices per month — does a salary amortise cheaply enough per invoice to compete. Below that, per-invoice pricing at $0.40 per invoice is almost always cheaper.
