Klarbon help centre

Answers on files and privacy, credits and limits, bank statements, email-in, phones, sign-in and billing, and rejected e-invoices.

On this page

The help centre answers how Klarbon works: what happens to your files, what credits buy, which bank statement files are supported, why balances may not match, email-in, phones, sign-in and billing, and rejected e-invoices. For anything not covered here, write to support@klarbon.app.

Write to support@klarbon.app. Describe what you tried and the message you saw, but do not send invoices or statements unless asked.

Where do I start if an e-invoice was rejected?
