BRL 100 and STEK are Dutch national certification schemes — full support today is NL-only. See our honest country-coverage disclosure.

Excel + papier

The de facto 'old way' — paper work order on a clipboard, Excel for F-gas balance, a binder for archiving.

Target audience
Installers who haven't yet made the switch to specialized software.
Price indication
€0 software costs — but hidden costs in time, errors and audit risk.
Koldwerk

Specialized platform for refrigeration installers in the Netherlands.

Target audience
Installers with BRL 100 or STEK certification, 1-50 installers.
Price indication
€49 / €69 / €89 per month (public) — cancel monthly.

BRL 100 / STEK audit trail
Without a demonstrable audit trail, any refrigeration installer fails their next Kiwa audit. Essential, not optional.
Present
Native audit trail, one-click export for Kiwa.
Not present
Manual logbooks — editable, so not demonstrable in an audit.
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, automatic GWP, alerts on deviation.
Not present
Excel spreadsheet — rarely comes out at zero without manual searching.
Time lost per work order
Direct effect on profitability.
Present
≈ 3 minutes per work order (customer + 3-step flow + signature).
Not present
≈ 15-25 minutes per work order (filling out the form + retyping + filing).
Loss risk (paper lost)
One lost work order = lost invoice + audit finding.
Present
Real-time sync to the cloud. Broken phone ≠ lost data.
Not present
One case of water damage in the van = a stack of work orders gone.
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.
Partial
€0 software costs, but hidden costs in time + errors.

When Excel + papier is the better choice

  • Your company handles ≤ 20 work orders per month and growth isn't a priority.
  • No BRL/STEK certification — no external audits, no pressure on the audit trail.
  • No installers on site — all administration happens at the office.

When Koldwerk is the better choice

  • ≥ 20 work orders per month: paper pays for itself faster than you'd think.
  • A BRL/STEK audit is coming — an Excel balance never reaches ≥ 99% closed.
  • Customers ask for PDF/digital history — paper is a churn reason.
  • Installer lost = paper work order lost = invoice 3 months later = cashflow problem.
