What happens if you do not do bookkeeping?
Without bookkeeping you miss tax filing deadlines (penalties: €200–2,000+), lose track of deductible expenses (overpaying tax), cannot produce financial statements for lenders or investors, and make pricing and spending decisions blind. The cost of NOT doing bookkeeping is always higher than the cost of doing it.
The immediate consequence is missed deadlines. VAT returns, tax returns, and statutory filings all require accurate books. Without them, you either file late (penalties, interest) or estimate — which means you overpay (because you missed deductible expenses) or underpay (which triggers audits and back-taxes).
The slower consequence is decision-making in the dark. Without current books, you do not know your real profit margin, your cash runway, or which products are actually making money. Businesses that run without bookkeeping for months often discover they have been losing money on their best-selling product — information that was buried in the data all along.
The most expensive consequence is the cleanup. When you finally do need books — for a tax audit, a loan application, or a business sale — reconstructing 12 months of unrecorded transactions costs 3–5x more than doing it monthly. An accountant reconstructing a year of messy records might charge €2,000–5,000; the same work done monthly would have cost €600–1,200.

Can I go to jail for not doing bookkeeping?
In most countries, simple failure to keep books is a civil offence (fines and penalties), not criminal. However, tax evasion — deliberately hiding income or inflating expenses — is criminal. Poor bookkeeping makes both mistakes look deliberate, which is how civil penalties can escalate.
What is the minimum bookkeeping I need to do?
At minimum: keep every invoice and receipt, reconcile your bank account monthly, and track income vs expenses. Even a spreadsheet with those three things is enough to file a basic tax return. The bar is low — but doing nothing is below it.
