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.

Use cases

How installers use this module day to day

Heat pump maintenance visit

The installer arrives, opens the work order on their phone, fills in the BRL-100 checklist, the customer signs — done in 5 minutes.

Leak check on a refrigeration installation

A leak-check work order automatically links to the refrigerant balance. Found a leak? Create an incident in one click.

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.
