# Zaitgeist: a bookkeeping agent for Swiss companies

An AI agent for turning receipts and bank statements into bookkeeping entries, with questions when details are missing and records you can review.

## From documents to bookkeeping entries

Zaitgeist brings everyday bookkeeping into a conversation. You submit a receipt
or bank statement, and the agent uses your company’s settings and Swiss
accounting guidance to record it. When an essential detail is missing, the
workflow calls for a question before the entry is made.

The conversation sits alongside a document archive and a view of the accounts.
You can inspect the books and return to supporting receipts without searching
through past messages. Changes are recorded so they can be traced later.

## Working through a bank statement

A statement can contain payments already recorded, familiar expenses, and
transactions that need a closer look. Zaitgeist separates these before preparing
new entries.

For example, a card payment matched to an existing entry is identified as
already recorded. A payment to a known supplier can use the company’s saved
expense category. If the purpose of a payment is unclear, it needs clarification
rather than a guessed description. This helps avoid entering the same payment twice
and makes unresolved items visible.

Statement imports support specific formats; not every bank export can be
processed.

## Keeping the books reviewable

Entries undergo consistency checks before changes are saved. Payroll
calculations also remain separate from recording the resulting payments.
The workflow checks that the payroll entries balance before saving them.

These checks catch problems such as entries that do not balance. They cannot
establish that every accounting decision is correct, so reviewing the books
remains necessary.

agent could complete its work more efficiently while preserving bookkeeping
quality.
