37 modules · one login
All modules in one place.
Koldwerk consists of 37 modules, all integrated: one login, one database, one audit trail. Nearly everything is included in every plan — Start too. The 5 modules with a plan threshold carry that label on their card.
BRL 100 and STEK are Dutch national certification schemes — full support today is NL-only. See our honest country-coverage disclosure.
25 of the 37 modules below have a translated title and summary, and 24 have a fully translated detail page. The rest show their Dutch text and link to the Dutch-only (NL) detail page, marked on the card.
On-site work
What the technician does in the van and at the customer.
Digital work orders
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. Audit-proof, linked to customer + installation.
BRL 100STEKEU 2024/573 F-gassen- From the Essentieel plan
LMRA — Last Minute Risk Analysis
Mobile-first LMRA on your installer's phone — required before the work order can start. On a CRITICAL "no" the app blocks the work and sends an approval request to the supervisor. GPS location, audit trail, works without signal — all in 90 seconds, all retrievable for 7 years.
VCA-VOLVCA-BasisBRL 100 Foto-annotatie op de werkbon
Pijlen, cirkels en tekst op de foto; het origineel blijft als bewijsstuk onaangetast.
BRL 100 (bewijsvoering onderhoud en reparatie)Dutch page (NL)Monteur-onderweg-bericht
Tikt de monteur op 'Onderweg', dan krijgt de klant een mail met wie er komt en tussen welke tijden.
Dutch page (NL)Compliance forms — custom checklists
Build your own checklist templates in Koldwerk. Version control built in: the published version stays frozen, edits automatically create a new version.

Customers and sales
From lead to signed quote to customer portal.

AVG/GDPRBRL 100Leads
Every lead on a kanban board with five status columns, with a colour indicator showing how long it's been since you last had contact. Once it gets serious, convert the lead into a quote in one click.
Quotes with online customer approval
Build the quote from the same material lines as your work order, send it in one click, and the customer approves on a simple page — no account needed. As soon as they approve, the draft work order is already waiting with all the lines on it.
Customer portal
Give your customer their own login. They see their installations, all signed-off work orders, and download PDFs themselves — and stop calling you for copies.
