## A new request

> **New words on this page.** **Ledger:** a company's own record of money in and out, also called its **books**. **Reconciled cash:** the cash a company really has at month-end, worked out from the bank's balance (the [overview](overview.md#you-do-not-need-the-earlier-cases) shows how). **Month-end pack:** the firm's name for the monthly report.


Lakeshore Supply had been a weekly client since February. Every week the firm's AI Worker in Slack, the worker, prepared a one-page cash file. A person approved it, and it went to Dana Ruiz from the firm's email address, `reports@`.

In late September 2027 Dana asked for something bigger.

*"Our bank wants a report after every month-end. A cover, a short memo and three slides. They look at one figure most of all: our reconciled cash. Can you do it by the fifth of each month?"*

Reconciled cash is the cash Lakeshore really has on the last day of the month, after the bank's record and Lakeshore's own record are compared.

> **The promise to the bank.** Lakeshore had promised its bank to keep at least **$195,000.00** in cash at the end of every month. If the figure fell below the line, Dana had to tell the bank.

The firm called the report a **month-end pack**.

## What it would cost by hand

Nisha asked Hamza how long the pack would take if he did it the way he had learned.

Each line is one payment in or out. The same payment should appear once in the bank's record and once in Lakeshore's ledger. **Matching** finds the pairs. What is left over needs a look.

Hamza wrote the steps on paper.

| Step | What Hamza does | Time |
|---|---|---|
| 1 | Download September's bank lines and Lakeshore's ledger (its own record of money in and out). About 3,400 lines each. | 1 hour |
| 2 | Match every bank line to a ledger line, in a spreadsheet | 8 hours |
| 3 | List what is left over, and work out reconciled cash | 1 hour |
| 4 | Type the figure and the leftovers into a memo | 2 hours |
| 5 | Type them again into three slides, and make a cover | 2 hours |
| 6 | Sana reviews, and Hamza fixes what she finds | 3 hours |
| | **Total** | **17 hours** |

*"Two days,"* he said. *"And step 2 is where I make mistakes. By line two thousand I am not reading any more."*

## Why not the worker?

Nisha asked the obvious question. *"The worker already checks Lakeshore's cash every week: a draft on Wednesday and the final file on Friday. Why not ask it?"*

Hamza shook his head. *"It checks one week on one page. The bank wants every line of the month matched, the leftovers listed, a memo in Sana's way and three slides in the bank's layout. That is a sheet, a memo, slides and a cover: four pieces that three of us must open and check. And the worker can send email from our address. I do not want the pack made in a place that can send it before we read it."*

Nisha agreed. The worker would keep its weekly job. It would also do one small daily check, which you will meet later, because it could already read the bank's lines. The month-end pack needed a place of its own.

Nisha had already told Dana a price: **$900.00** for each pack, on top of the $1,500.00 a month for the weekly file. She had based it on two days of work.

## What the firm already had

Nisha looked at Hamza's list for a long time. Then she wrote a second list beside it: the things the firm already used with Claude.

| What the firm had | How the firm used it |
|---|---|
| A **project** | Nisha kept one for her own notes |
| A **skill** | Sana had saved her way of writing a review memo |
| **Connected apps** | The shared drive was connected to Claude |
| **The worker in Slack** | It could read the bank's lines and the drive, and send email from `reports@` |
| The **desktop app** | Hamza used it to ask about files on his computer |
| **Scheduled tasks** | The worker's weekly file ran on one |
| **Artifacts** | Each of them had made a doc or a deck, now and then |

*"We have every part,"* she said. *"We have never used them together. Each of us opens a chat, pastes something in, and copies something out. The copying is the two days."*

Sana agreed, with one condition. *"I do not care how the figure is made. I care that I can check it, and that my name is not on anything I have not read."*

*"That does not change,"* said Nisha. *"It is the only part that should take our time."*

![The old way and the new way. Two panels. On the left, by hand, 17 hours every month: download, 1 hour; match 3,400 lines, 8 hours; work out the figure, 1 hour; type the memo, 2 hours; type the slides and cover, 2 hours; review and fix, 3 hours. On the right, with the setup, about 2 hours of people's time every month: the setup reads, matches, computes and builds in about 25 minutes; Hamza checks, 1 hour; Sana reviews, 45 minutes; an approval, 15 minutes. A band at the foot says the setup is built once, in one afternoon. The times are illustrative.](img/the-old-way-and-the-new-way.png)

## The plan for Monday

They gave themselves one afternoon, Monday, October 4, to build what Nisha called **one place for Lakeshore**. On Tuesday they would run it for the first time, for September.

Nisha set one rule before they began.

*"Claude may read, compute, build and repeat. A person checks, approves and tells the client. If we find ourselves copying a number by hand, we have built it wrong."*
