Digital work orders
Paper work orders cost you an hour a day — and they go missing right before an audit.
With Koldwerk your installer fills in the work order on their phone, the customer signs on-site, and you have the PDF in your inbox within 30 seconds. Stored audit-proof, linked to customer + installation.
BRL 100 and STEK are Dutch national certification schemes — full support today is NL-only. See our honest country-coverage disclosure.
What it does
- Step-by-step flow on the phone: confirm customer + installation, work performed + checklist, materials, refrigerant, signatures.
- Auto-numbered per year (`2026-0001`, `2026-0002`, …) per workspace.
- Customer and installer signature on canvas, stored as PNG.
- PDF export with your company logo, customer details, installation specs, pressure readings, refrigerant mutations.
- Status flow: CONCEPT (draft) → AFGETEKEND (signed-off) → GEFACTUREERD (invoiced), with an audit trail at every transition.

How installers use this module day to day
Heat pump maintenance visit

Repair + materials
Materials and hours are logged on the work order and pushed to the Debitan integration — no duplicate admin.
FAQ
Frequently asked questions
Does it work in the van without signal?
Yes. Drafts are stored locally on the phone and sync automatically once there's a connection again.
Can a work order still be changed after it's been signed off?
No. Per the BRL-100 requirement, a signed-off work order is immutable. Changes require an additional work order with its own audit trail.
What does the customer-facing PDF look like?
A professional design with your logo, customer details, installation details, all work performed, materials, refrigerant mutation, and both signatures.
