What happens when an AI bookkeeper makes a mistake?
Two layers of protection. First, most mistakes never happen: anything uncertain stops in a human approval queue before it reaches the records. Second, if finished work is still wrong, you report it within 14 days and the unit price returns as credit, with the record corrected free — up to a monthly cap while the service is new.
The approval queue is the main defence. An invoice with a duplicate number, a VAT rate that does not match the supplier, or a field the AI cannot read is not entered — it is sent to you with a question, and the answer decides the entry. Guessing is the failure mode the design removes. Nika works exactly this way, and the compensation policy is published, not hidden.
For finished units, the compensation is mechanical: report within 14 days, get the price back as credit plus a free correction. There is a monthly cap while the service is new, because an unproven service promising unlimited liability is a promise it cannot keep. The invoice cost calculator shows the economics of getting this right the first time.

Is there a guarantee for AI bookkeeping errors?
Yes, published: report a mistake within 14 days and the unit price returns as credit with a free correction, up to a monthly cap while the service is new. The cap exists because an unproven service should not promise unlimited liability.
Can AI bookkeeping send money or delete records?
No. Hard rules apply to every AI employee: never send money, never delete anything, never act on an unclear case without confirmation. Those rules are part of the published design.
