Section: AI at Work. Verdict: ACT
Who it is for: Accounting firms, insurance agencies, staffing firms, builders and other businesses that start a job with documents. 10 to 100 employees. Owner or office manager.

A bank used an AI agent to put new clients' records into one standard format, and staff review what the agent is unsure about. A business that starts each job with a pile of documents can use the same pattern. Start with ten finished jobs.

## Why
Northern Trust, a bank, unveiled the agent on Nov 9, 2026. It converts years of client records from many formats into the bank's standard format. Data preparation took two and a half weeks before. The bank reports it now takes three days. That number covers preparation only. The bank tested the agent on data with client names removed, and staff handle the uncertain items. Many businesses have the same step. A new customer sends statements, forms and past records in different layouts, and someone types them into the system.

## Steps
1. Pick the job type where staff type the most from customer papers.
2. Time that step on your next ten new customers.
3. Write your standard sheet: the facts you need from every new customer, in one order.
4. Take ten finished jobs. Remove names, account numbers and ID numbers from the papers.
5. Have an AI tool the business has approved read the papers and fill in the sheet. Ask it to mark each item it is unsure about.
6. Have the person who did the original work compare the two results and count every error.
7. Use it on new customers only if the error count is low.
8. On live work, a person checks every marked item and every number that money depends on.

## What data may go in
For the test: papers with names, account numbers and ID numbers removed. For live work: only a tool whose terms the owner has read.

## Who checks the output
The staff member who owns the job checks every marked item. The owner or a senior person signs off before anything goes to the customer.

## Cost and time
The report gives no cost. The bank built a custom system with Microsoft. A small business starts with an AI tool it already pays for. About one day for the first ten.

## The rule to check
Customer papers often hold personal and financial data. Use a tool whose terms say it does not learn from what you upload. Some industries add their own rules, so ask your adviser before live use.

## What can go wrong
The bank reports a first-pass quality score above 96%, so staff still find and fix the rest. One wrong number can change a quote, a tax form or a policy. A person checks the numbers before anything goes to the customer.
