AI Business OS — eight AI assistants, add-on from €29/month excl. VAT

On top of any plan. AI Start €29 (1 assistant), AI Team €89 (3 assistants), AI Business Autopilot €179 (all 8). The assistants read your own data and prepare work: internal steps such as a lead or a draft quote run directly, anything that reaches a customer waits for your approval. First 14 days free, then invoiced by bank transfer, cancel monthly. Full details are on the Dutch module page.

No time to set it up yourself? Full Setup Service — one-time €249 excl. VAT

We enter your company details, import your customer list, set up your materials catalog, and work with you to decide which modules are relevant. You get a working workspace instead of an empty dashboard. We'll reach out within 1 business day of your request.

Frequently asked

What happens if I go over my user limit?
An extra user costs €9 per month on Essential and Plus. This is not automatic: there is no automatic overage invoice and no automatic warning either. Need one more seat? Email hallo@koldwerk.nl and we adjust your subscription by hand; you see it on your next invoice.
How do I get started with Koldwerk?
The first 14 days are free to test Koldwerk — no credit card required to sign up. Like it? Then choose a plan and you receive an invoice that you pay by bank transfer — no automatic direct debit. If you haven't chosen a plan within 14 days, access pauses — your data stays safe. Choose a plan later and everything works again once your payment has been received and processed (usually within 1 working day of receipt).
Are BRL 100 and STEK included in every plan?
Yes. All modules — work orders, refrigerant admin, audit trails, customer portal, certificate archive — are included in every plan. The difference between Start/Essential/Plus is the number of users and advanced features (Debitan sync, API, SSO).
Can I cancel monthly?
Yes. No annual contract, no notice period — you cancel in your settings and only pay for the current month. On cancellation you get 30 days to export your data under the data-processing agreement.

Honestly priced

On Start, Essential and Plus what you see here is what you pay: public pricing, no setup fees, cancel monthly from Settings › Subscription. Enterprise is custom — that one does involve a conversation.
