Welcome to ista.

At ista Nederland, everything revolves around accurate and transparent billing. This process does not begin with the invoice, but with the agreement made with the customer. Every contract contains arrangements regarding metering points, allocation keys, tariffs, and indexation. Someone has to translate these arrangements into a functional setup within our systems. That is your role.

As a Contract Support Officer, you are responsible for translating customer agreements into a practical billing structure. You ensure that costs are allocated as agreed with the customer, and that the structure is correct, complete, and remains up to date. You break down complex agreements and convert them into a clear technical and financial structure.

This is work where details are crucial. An incorrectly recorded allocation formula or a missed indexation clause affects hundreds of settlement statements and only comes to light months later. That is why we are looking for someone who works meticulously, checks their own work, and does not hesitate to raise the alarm as soon as an agreement is unclear, contradictory, or unworkable.

Our office is based in Schiedam.

Responsibilities

From contractual agreement to a working billing design

You translate contractual agreements into a practical billing design within the relevant systems.
You determine and document the allocation methodology, ensuring that the cost allocation aligns with what has been agreed with the client.
You convert complex or non-standard agreements into a workable technical and financial structure.
You identify unclear, contradictory, or unworkable agreements and raise these with the relevant colleague or the client in good time.
Check in advance whether a proposed arrangement is practicable before it is formalised.

Set-up and management of properties and contracts

Set up new properties administratively and record meter readings correctly.
Process and check contracts and contract amendments.
Monitor the accuracy, completeness, and up-to-date status of contract data across the various systems.
Document agreements and changes carefully, so that a colleague can follow and take over your work.

Collaboration and support

Support internal and external stakeholders with queries regarding contracts and billing.
You work closely with Sales, Billing, and Operations to ensure agreements remain feasible.
You assist with the annual indexation and the invoicing of service charges.
Help us improve our working methods so that recurring errors can be resolved at source.

Requirements

You have a working and thinking level equivalent to MBO+ or HBO.
You have at least two years’ experience in an administrative or operational role, preferably involving contract processing, customer data, or process monitoring.
You work with great attention to detail and check your own work before handing it in.
You can break down a complex arrangement into its constituent parts and convert it into logical steps, rules, and amounts.
You are proficient in Excel and quickly get to grips with new administrative systems.
You should carefully record agreements and changes in writing.
Pré: You have experience in the property, energy, or sub-metering sector.

We Offer

A role that has a direct impact on the quality of our invoices and, consequently, on customer satisfaction.
