Question 1

Is Koldwerk a good alternative to Werkbonapp?

Accepted Answer

For refrigeration companies with BRL 100, F-gas, or STEK obligations, Koldwerk is a strong alternative to Werkbonapp: that compliance is built in by default. If you don't have those requirements, Werkbonapp may suit you better — weigh it against the comparison below.

Question 2

When is Werkbonapp the better choice over Koldwerk?

Accepted Answer

Your company is broader than refrigeration alone — Werkbonapp is generic enough for plumbing/electrical/heating. Compliance requirements are light: no BRL 100, no F-gas balance, no STEK participation. You mainly want 'a quick digital work order' and not 'audit-proof administration'.

Question 3

When does Koldwerk fit better than Werkbonapp?

Accepted Answer

You have BRL 100 or STEK certification — you need an audit trail that Werkbonapp doesn't offer. Refrigerant balance needs to close on kg + CO₂-eq for F-gas annual reporting. You want LMRA, installer certificates and maintenance contracts in one system — not three separate tools. A customer portal for end customers to view their own work orders + installation history.

Question 4

What exactly is Werkbonapp?

Accepted Answer

Generic digital work-order app for installers and contractors, NL market, around since 2016. Target audience: Small-SME installation companies (plumber, electrician, refrigeration) without heavy compliance requirements. Price indication: From roughly €15 per user / month (publicly available, no annual contract).

Feature	Koldwerk	Werkbonapp
BRL 100 / STEK audit trail Without a demonstrable audit trail, any refrigeration installer fails their next Kiwa audit. Essential, not optional.	Present Full audit log with hash-chaining, BRL-100 events, periodic exports for Kiwa.	Not present No specific BRL/STEK implementation — generic work order without a compliance layer.
F-gas balance + GWP calculation EU 2024/573 requires a closed balance per refrigerant type. Excel never hits zero — the auditor will ask why.	Present Live balance per refrigerant type, built-in GWP table, annual reporting export.	Not present Not present in the public offering (checked on werkbonapp.nl).
Mobile-first installer app Installers work in the van, often without WiFi — offline-first is a hard requirement.	Present PWA /m/* with service worker: visited pages keep working out of coverage, and signed-off work orders sync automatically once there's a connection.	Present Werkbonapp has its own iOS/Android app.
LMRA for VCA compliance Last Minute Risk Analysis is mandatory for VCA-certified companies.	Present LMRA templates, offline completion, installer + supervisor sign-off.	Unknown Not explicit in the public offering.
Maintenance contracts + service-visit planning Recurring maintenance is the core of refrigeration work — it needs to be scheduled automatically.	Present Contract templates, auto-generated service visits, reminders.	Partial Scheduling present; contract templates unknown.
Honest price + cancel monthly No annual-contract lock-in. Our price is public (from €49/month) instead of 'request a quote'.	Present €49/€69/€89 public on /en/prijzen. Cancel monthly.	Present Per-user pricing, no package tiers. Cancel monthly.
