Match bank statements and invoices automatically with AI

It compares financial records from different sources, flags mismatches, and only asks you to check the unclear ones.

How the work actually flows

It branches. Exactly one path is taken; runs once per each new financial record.

The problem it solves

Reconciling bank statements against invoices by hand eats up hours every month, and small mismatches are easy to miss. You end up cross-checking spreadsheets line by line, hoping you didn't overlook a duplicate or a missing transaction.

Who it fits

Finance and accounting teams that reconcile transactions across multiple systems.

How it works

  1. New financial data arrives from your bank, invoices, or accounting system
  2. The system standardizes every record into a common format
  3. It matches records first by exact details like amount and date
  4. AI reviews the remaining unclear cases using fuzzy matching and assigns a confidence score
  5. High-confidence matches are reconciled automatically, and the rest are flagged for review, with results logged to Google Sheets and a summary sent to Slack
What you get

Transactions matched automatically, with only the unclear ones for you

Your bank statements and invoices get matched automatically, and only the unclear cases are flagged for your review.

What you get

A reconciliation log in Google Sheets showing matched, unmatched, and flagged transactions, plus a Slack summary.

What you need

Google Sheets, an OpenAI account, and a Slack workspace, plus a way to send in your financial data.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
