What a Change Order Ticket Is

A change order ticket, also known as a “meerwerkbon”, is a short form that records work that falls outside the original quotation. It provides written proof that the additional work has been agreed upon and clarifies the cost for both contractor and client.

When to Use a Change Order Ticket

Use the ticket for any work that was not included in the original quotation, regardless of the amount. Typical situations include:

  • Adding an extra socket or light fixture
  • Discovering moisture, rot, or other hidden defects
  • Adjustments requested by the client or architect

Documenting even small changes helps avoid disputes later on.

Adding Photographic Evidence

For unforeseen issues (e.g., water damage, asbestos), take a photo before you start work. This visual record supports the need for the extra work. When the change is client‑driven, note the discussion (e.g., “discussed on site 15/03/2026”).

Pricing Options: Fixed Price vs. Time‑and‑Materials

SituationSuggested Pricing
Work you can estimate accurately (e.g., installing a socket)Fixed price
Work with uncertain scope (e.g., repairing hidden moisture)Time‑and‑materials with hourly rate and estimate

If you choose time‑and‑materials, keep a daily log of hours spent. The log can be attached to the ticket and later to the invoice.

Invoicing the Change Order

Add the change order as a separate line item on the invoice or issue a dedicated invoice for the extra work. Example wording:

Change order dated 15/03/2026: relocate bathroom drain, per ticket #3, €1,200 excl. VAT.

Attach the signed ticket to the invoice to provide the client with the written agreement.

Digital vs. Paper Process

Both approaches are acceptable as long as the ticket is signed and stored.

  • Digital: Create a new project item in your management system, attach photos, description, and price, and let the client approve it through a portal.
  • Paper: Print copies, keep them in your vehicle, and obtain signatures on site.

For a digital workflow example, see the relevant page on the Enfin website.
