the glossary

The words your bookkeeping gets stuck on.

VAT (btw), invoices, deductions and bookkeeping, explained in plain language. For each term you see where it is in the law, how it comes back in basestep, and which two mistakes are made with it most often. The tax explanation on this page follows Dutch law and is written for Dutch sole proprietorships (eenmanszaak).

38 terms

VAT

What you pay, what you reclaim, and which period it belongs to.

Invoices and payment

From quotation to formal demand: what an invoice must contain and what you may do when a customer does not pay.

Income tax

The deductions and thresholds a sole proprietorship (eenmanszaak) runs into every year.

Bookkeeping

The parts of your bookkeeping you meet as soon as you have to export or prove something.

why there are not more

Every term deserves its own content, or it does not exist.

A glossary is easy to inflate: a hundred pages with a template and a changing word in it. That brings reach and no value, and it is exactly what the quality bar of this site forbids. A term only appears here once it has its own explanation, its own example and its own pitfall. That means 38 terms now, with a ceiling of 40, and not more because it is possible.

Facing the bigger step? The main guide walks through the nine steps between a working prototype and a project that runs. If you want to read a term in its context, the knowledge base works out one topic per article.

This is general information, not tax or legal advice. basestep calculates and explains; you file yourself. If you are unsure about your situation, consult an adviser.

From first prompt to tax return.

The glossary stays free and without an account, even if you never do anything with basestep.
