Customer communication for energy suppliers
Energy suppliers are faced with the task of producing millions of documents on time, without errors and across all channels. INVARIS automates your billing communication, simplifies regulatory adjustments and enables digital self-service processes for your customers. From annual statements to tariff change confirmation: one platform for all output formats.


The challenges of the energy sector
Complex billing logic for high document volumes
Every year, energy suppliers process several million billing documents with variable tariffs, consumption values and tax components. Regulatory changes, such as price brakes, new duties or changed information requirements, require rapid adjustments to existing templates. The combination of complex calculation logic and high time pressure makes manual change processes risky and expensive.
Expectations for digital transparency and self-service
Customers today expect more than just a paper bill in their mailbox. You want to manage contracts online, digitally transmit meter readings and carry out tariff changes without waiting times. Energy suppliers must seamlessly integrate these digital touchpoints into their existing communication landscape without having to operate and maintain additional systems in parallel.
Consistency and traceability in series production
When creating hundreds of thousands of documents within a few days, stable processes and the highest quality are essential. Every invoice must be comprehensible, and every change must be fully documented and versioned. At the same time, corporate design, legally approved text modules and binding format requirements must be consistently implemented across all documents. Additional peak periods, such as in the context of annual billing, require reliable processing within narrowly defined time windows.
This is how INVARIS supports energy providers
Dynamic templates for variable billing content
Control billing, contract documents and customer communication with INVARIS Designer as dynamic templates that automatically adapt to different tariffs, customer groups and regulatory requirements. Your specialist departments create and change templates on their own, without having to wait for their IT department, for example. You can maintain text components conveniently and centrally in INVARIS ContentRepository so that content can be updated quickly and consistently.
Controlled change processes with INVARIS ResourceManager
Regulatory adjustments are managed centrally in INVARIS ResourceManager and transferred to production in a controlled manner using defined approval processes. Time-controlled production deployments make it possible to activate changes exactly on the cut-off date. Full versioning documents which template was used and when in which version.
Stable mass processing in output management
INVARIS Output Management reliably processes high volumes of documents even during peak times such as annual billing. Parallel processing pipelines, real-time monitoring and automatic error handling ensure timely production. The multichannel edition serves print, email and customer portals from a single processing run.
Accessible and archivable output formats
INVARIS creates documents in all relevant formats: print-optimized PDFs for mailing, PDF/A for long-term archiving and PDF/UA for barrier-free communication. Parallel output in multiple formats takes place without additional configuration effort.

What energy suppliers particularly need
Online forms for customer interactions
Integrated online forms for meter reading, relocation reports and tariff changes significantly reduce service costs and improve data quality at the same time. The forms are responsive, can be seamlessly embedded into existing customer portals and transfer collected data directly to specialist applications. Checks as you type reduce queries and post-processing costs.
Barrier-free customer communication
The preparation of barrier-free invoices in accordance with the PDF/UA standard helps energy suppliers reduce complaints and roll out digital delivery on a wider basis. Customers with visual disabilities can capture their documents with screen readers, which increases customer satisfaction and meets regulatory requirements.
