Bookkeeping basics for startups: what to track from day one

In the early days of a business, all the attention goes to the product, the customers and growth — not the bookkeeping. Yet what you track from day one determines how smoothly the rest of your entrepreneurship goes.

Keep business and personal separate

Open a dedicated business account from the start, even if it's not legally required for your structure. It keeps your admin clear, and avoids arguments with the Belastingdienst over what counts as business or not.

Get your invoicing right

An invoice has to meet legal requirements. The main ones: a sequential invoice number, the invoice date and the date you delivered, your own name and address as well as your client's, your VAT identification number and KvK number, a clear description and the quantity of what you supplied, the amount excluding VAT, the VAT rate and the VAT amount separately. This is a selection: further rules apply, among them shifted VAT, supplies abroad, and simplified invoices for small amounts. Run your own invoice template past the full list of invoice requirements once; incomplete invoices can cause problems in an audit, including for your client, who may then not deduct the VAT.

Keep every receipt and expense

Keep all receipts and invoices for business expenses, digital or on paper, for at least seven years. It's not just a legal requirement — it also determines how much input VAT you can reclaim, and which costs are deductible.

Set money aside for tax

A classic beginner's mistake: spending every euro that comes in, without setting anything aside for the VAT and income or corporate tax you'll owe later. Structurally reserve a percentage of every incoming payment in a separate savings account.

Bring in help early

Many startups wait to bring in a bookkeeper until they're already behind. Whereas a solid structure from the start costs less time — and money — than untangling a messy administration later.

Startups get support from day one with bookkeeping that grows with them, so you can focus on building your business.
