Short read — Building your business

The actual stack you need to launch

Not the stack someone with a team of ten needs. Not the glossy enterprise setup you'll grow into. This is the lean, honest list of what it takes to run a real business solo — legally covered, financially sane, and actually productive from day one.

Your progress0 / 9

Foundation — do these first

KVK registration first

Before anything else. Your KVK number is the foundation — you need it for your bank account, contracts, invoices, and insurance. Everything else waits for this.
A real business bank account

Revolut Pro does the job. Free tier is fine to start, keeps business and personal separated from day one, and the app is actually good. Don't mix money.
Liability insurance

Cheap. Easy. Non-negotiable. A basic aansprakelijkheidsverzekering costs less per month than a nice lunch and covers you when a client claims something went wrong. Get it before you sign your first contract.
AOV — income protection

The one nobody wants to think about. If you can't work, you can't invoice. A lean AOV doesn't have to be expensive, but skipping it entirely is a gamble most solo operators lose eventually.

Operations — how you actually run things

Bookkeeping — something that just works

GetGekko, Moneybird, whatever you'll actually use. The goal is not spending half a day on your quarterly VAT return. Pick a tool with BTW filing built in and automate what you can.
CRM / project management

Even if you're running one project at a time, something like Odoo keeps client info, follow-ups, and pipeline in one place. A spreadsheet works too — the point is having a system, not which one.
A domain you own cheap

Spaceship, Porkbun, wherever — just own your domain. A .eu or .nl gives you instant local credibility. Pair it with a professional email (custom domain, not Gmail) and you immediately look less amateur.

Infrastructure — the quiet stuff that makes everything work

Storage and backups

iCloud+, Dropbox, whatever. Store your contracts, proposals, and client files somewhere that isn't just your laptop. If it only exists locally, it doesn't exist.
A machine you trust

Your hardware is your business continuity plan. Use native apps where you can — they're faster, less janky, and don't require a browser tab to keep open. Keep it maintained. Back it up.

This isn't a blueprint — it's a floor. You don't need all of it on day one, but you do need to know what you're deliberately skipping and why. The businesses that quietly fall apart usually aren't missing the big things. They're missing three of these small ones at once.
