How it works

In three steps
from XS4ALL to sevDesk

1

Connect XS4ALL

Store your XS4ALL login once, securely – the browser agent fetches the receipts and you confirm 2FA via Telegram.

2

Receipts are fetched automatically

belege.ai collects your XS4ALL invoices and fee receipts automatically and matches them to the right bank transaction – even later, when they arrive after the fact.

3

Book to sevDesk

belege.ai creates the receipt in sevDesk automatically. Since sevDesk has no open API, the browser agent signs in securely – you confirm 2FA via Telegram.

Why belege.ai

XS4ALL receipts,
automatically in sevDesk

Logs in for you

XS4ALL-Belege liegen hinter dem Login – der Browser-Agent meldet sich für dich an und lädt den passenden Beleg, 2FA bestätigst du per Telegram.

No receipt gets lost

If a receipt is missing for a XS4ALL payment, the agent reaches out on its own – and, if needed, proposes a legally compliant self-receipt so the transaction doesn't stay open.

Filed automatically in sevDesk

Receipts and approved hospitality receipts land in sevDesk automatically – no open API needed, via the secure browser agent.

Tax-compliant & GDPR

Servers in Germany, encrypted credentials, no training on your data.
