Build an AI reconciliation agent instead of paying $1K+/month for bookkeeping

Result

self-reported

Saved about $12K per year in outside bookkeeping; agent flags mismatches across bank statements, books, and email.

Elliott Michael Smith built an agent that connects to his accounting software and email through APIs, checks bank statements against the books and related threads, and flags anything that doesn’t match — including a year of contractor payments dumped into one account.

Try it now

  1. Connect read-only access to accounting software and the email inbox that holds invoices/receipts.
  2. Ask the agent to compare bank lines to book entries and related email threads; list mismatches only.
  3. Fix the flagged items yourself (or with your bookkeeper) before granting any write access.
Copy-paste prompt
You are my reconciliation agent. Using read-only access to [accounting tool] and [email], compare bank statement lines for [period] to booked transactions and related invoice threads. List every mismatch: possible double pay, wrong account, missing invoice, or lumped categories. Never change the books. Never invent a match.
