# See it run

The reference console keeps the books of Lantern Hill Coffee Roasters, a made-up roaster with a café, a hospital kiosk, wholesale and online sales, and a separately owned sister café. A coding agent built it, working only through GAAPcore's API.

## The tour, in stills

Each stop below is in the walkthrough. Every figure on screen comes from GAAPcore. The console stores people and approvals, not money.

![The trial balance screen, with the line "In balance" above a list of accounts and their debit and credit balances.](https://chappellai.us/img/see/trial-balance.webp)

**1\. Trial balance.** Lantern Hill's trial balance, in balance. Below it, the subledger tie-outs: receivables, payables, inventory, bank, assets and leases each agree with their control accounts.

![The Accounts receivable account, listing each entry with its date, source document, amount and running balance.](https://chappellai.us/img/see/account.webp)

**2\. Into an account.** One click from a trial-balance line to the account: every entry that moved it in the period, with running balances.

![A journal entry panel for a customer invoice: two balanced lines, and "Posted by Bill C through writer console".](https://chappellai.us/img/see/journal-entry.webp)

**3\. The journal entry.** The entry GAAPcore posted, stamped with the writer that sent it (console) and the person who asked (Bill C).

![The customer invoice panel: customer, dates, the service line and the total.](https://chappellai.us/img/see/source.webp)

**4\. Back to the source document.** From the entry to the document that caused it, here a customer invoice. Nobody typed this entry; the invoice produced it.

![The post-journal dialog showing "GAAPcore refused this CONTROL_ACCOUNT_RESTRICTED", naming line 1 and the reason.](https://chappellai.us/img/see/refusal.webp)

**5\. A refusal, shown to the user.** A manual journal straight to the bank's cash account. GAAPcore refuses with CONTROL\_ACCOUNT\_RESTRICTED, and the console shows the reason, down to the line. Nothing posts.

![The month-end checklist: banks, depreciation and lease runs, allowance, subledger tie-out, and a draft that blocks the close.](https://chappellai.us/img/see/close.webp)

**6\. The month-end close.** A checklist read from the books. Each step says where it is done, and what still blocks the close, in GAAPcore's words.

![Group statements for the Lantern Hill group: the two members, the group after eliminations, and the elimination worksheet.](https://chappellai.us/img/see/consolidation.webp)

**7\. The sister café and the group.** Lantern Hill Café is a second company that buys its coffee from the roastery. The group statements combine the two and list every elimination with its reason.

![The command palette open over the accountant's view, with "trial" typed and "Trial balance (today)" highlighted.](https://chappellai.us/img/see/palette.webp)

**8\. Ctrl+K.** Every screen and action is one search away.
