What they did
Her bookkeeping bot Peg worked through April overnight, matching receipts and searching personal accounts and cards for possible business expenses, following rules they'd written together and listing questions for her to review in the morning.
Result (as claimed)
Reconciliation is down to a short human review.
Tools they used
Cost: Grok Bot: from $30/mo.
Set it up
Gather the documents
Collect statements, bills, invoices or tax documents for the period you want reviewed.
Ask for an audit, not actions
Have Grok Bot list findings, amounts and suggested next steps before it does anything.
Approve each action
Approve cancellations, disputes or payments one at a time. Never give an agent open-ended access to move money.
Track the result
Record what changed and what you saved so you can check it next month. This is not financial advice.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
