Step by step

The insurer context still matters

A new address with CSS can affect correspondence, premium region and sometimes canton. PrimAI turns this small change into a clear app task. PrimAI is not paid by CSS or another insurer. Neutrality matters because CSS decisions can be administrative, financial or family-related, not only commercial.

01

The insurer context still matters

CSS is common in Swiss households and many documents are already digital. PrimAI helps avoid confusing an available document with a ready decision. PrimAI is not paid by CSS or another insurer. Neutrality matters because CSS decisions can be administrative, financial or family-related, not only commercial.

  • CSS policy
  • Digital documents
  • Neutral
02

The real risk in this task

The risk with a CSS address change is treating it as a single line of text. In Switzerland, address can influence premium region, correspondence language, invoice delivery, household members and sometimes canton context. If several people are insured together, it also matters whether the address concerns one person, the whole family or only correspondence.

03

What to check before preparing the document

Before preparing the message for CSS, PrimAI places old address, new address, moving date, insured person, policy number and municipality in one workflow. That makes it easier to see whether the change should also trigger a new premium comparison, model check or document update.

04

What PrimAI keeps separate for this insurer

You scan your CSS policy, check the recognized fields and the app guides you to the right task. The page gives context; the app prepares information and documents without making you retype everything.

  • CSS policy
  • Digital documents
  • Neutral
05

Connection to comparison, deductible and model

Supplementary cover should be read separately from basic insurance. That separation prevents a cancellation from becoming too broad and lets you decide calmly whether a cover should stay, be checked or simply be documented.
