Balance, Aug 31
- Agreed to the statement. Opening equals the prior statement's closing; closing equals the running balance after the last line.
- FFooted. The column recomputed from the statement's lines equals the statement's own total.
- CFCross-footed. Opening plus receipts minus disbursements equals closing, on the row.
- SCleared later. Every item appears on the next statement, or in the September activity to Sep 24, with its date.
- GLAgreed to the ledger. Equals the account's balance in the trial balance of books v3.
The business card x7715 is a liability, not cash. Its August statement shows 23,304.69 owed; account 2100 shows 23,304.69. The July statement was paid from operating on August 25, 20,120.45: a lower liability, not an expense.
Statement and ledger agree in June, July and August.Computed here from the statements and the books. It is not a reconciliation run in QuickBooks, where reconciling is its own step with the statement's ending balance and date, and QuickBooks keeps a report when it is finished (Intuit).

Line items (crane operation, mobilization/demobilization, and a rigging crew) total $11,600.00 + $2,850.00 + $4,200.00 = $18,650.00, which matches the invoice total and the extended math checks out (8 hrs x $1,450.00 = $11,600.00; 4 workers x 8 hrs x $131.25 = $4,200.00). Because the vendor is supplying operated equipment plus a labor crew for a discrete project task rather than bare equipment for Harrow Lane's own crew to operate, this is best coded to 5100 Subcontractors (direct job cost against the RTU-4 project, offsetting 4100 Project and repair revenue) rather than 5300 Equipment rental. No prior invoice, credit memo, or duplicate indicators were found in the document; the invoice number KCR-3391 has not been seen before in this conversation, so it is treated as a new, standalone invoice.

Decision and posting
Accrue 18,650.00 in August as proposed, or leave it in September with a written reason. Until then August's result is not approved; cash stays reconciled.

One caveat for the accountant: the recovery tank is priced together with the refrigerant in a single line, so its individual cost isn't broken out; if it is a durable tool above your capitalization threshold, you may want to split and capitalize it separately - the chart provided has no fixed-asset/tools account, so I defaulted the whole invoice to Materials and parts pending your judgment."}Shown as recorded, long dashes printed as hyphens.

Refused. 3900 Owner's draw: no such account in this chart (an S corporation: equity is 3000, 3100 and 3200). The policy never codes a transaction with the owner to equity by itself: the line waits for the accountant, and no EBITDA adjustment is made here.
Seeded for the test. The model proposed 1250 Due from shareholder from the owner's email. This automatic owner's draw coding, as a bank rule would do it, was written for the test.

Decision and posting
No decision needed: the controls held.
Refused. Categorize instead of match: the ledger already holds this receipt (C-0001, in transit since 2026-07-31). A second entry would put 150,000.00 more in August's ledger receipts than the bank's adjusted receipts, and 150,000.00 of revenue that was never earned.
Seeded for the test. The model matched the line to the transfer already recorded. This categorization as revenue, what an automatic rule on incoming ACH would do, was written for the test.
- Matched to C-0001. No new entry: the transfer was recorded on 2026-07-31.

QuickBooks Online, in Intuit's words
- Match it, or Categorize it. N-2: the August 3 credit is matched to the July 31 transfer; categorizing it would record the money twice.
“Match it: Choose this option if you already entered a record for the transaction in QuickBooks. Categorize it: Choose this option if you don't have an existing record. This creates a brand-new record in QuickBooks.” Match online bank transactions in QuickBooks Online, read September 25, 2026.
- For review is not in the books. The August bank and card lines were in that state in the fictional export: nothing of them was in the books.
“They appear in the For review tab, but they won't affect your books until you match or categorize them.” Match online bank transactions in QuickBooks Online, read September 25, 2026.
- Reconciling is its own step. B-1 is computed here from the statements and the books; no QuickBooks reconciliation was run.
“Enter the Ending balance and Ending date from your account statement. [...] After finishing, QuickBooks saves a reconciliation report.” Reconcile an account in QuickBooks Online, read September 25, 2026.
- The closing date: a warning or a password. N-7: QuickBooks guards changes to transactions dated on or before the date. The circuit applies the same date line to the new postings it makes, and stops outright instead of warning; the override is the accountant's.
“If someone tries to change or delete these transactions, QuickBooks will either give a warning or ask for a password, depending on your settings. [...] Any attempt to change transactions dated on or before the lock date will trigger the warning or password prompt you set.” Lock your books in QuickBooks Online, read September 25, 2026.
- Error 6210 through the API. N-7: an integration cannot use the password route; the decision goes back to a person.
“The account period has closed and the account books cannot be updated through through the QBO Services API. Please use the QBO website to make these changes.” 6210 Account Period Closed (Intuit Developer Support), read September 25, 2026.
- Bank rules that post by themselves. H-1: the July transfer went to expense through such a rule. A review circuit only controls what does not bypass it.
“If you turn on auto-add, QuickBooks applies the rule to any downloaded transaction it applies to and posts it immediately. Remember to use this with caution, because if you leave it on you won't get a chance to review transactions before QuickBooks adds them to your books.” Set up bank rules to categorize online banking transactions (the option is now called Auto-post), read September 25, 2026.
- Request IDs. N-5: the retry reuses the attempt identity and first reads what the record holds.
“We strongly recommend you use request IDs for requests that write, modify, or delete data. This guarantees idempotence.” Basic ID and field definitions (Intuit Developer), read September 25, 2026.
- One payment, several invoices. N-3: a split payment is normal work, applied as the customer's advice says.
“Select the checkbox for each invoice you are recording a payment for. If you select multiple invoices, the open balance for each appears in the PAYMENT column.” Record invoice payments in QuickBooks Online, read September 25, 2026.
- Refund after a credit memo. H-2: the June refund had been coded to revenue instead, reducing the sale a second time.
“Next, create an expense to record the money you are refunding to the customer. [...] In the Category column, select the Debtors account (Accounts Receivable). [...] Finally, link the credit memo and the expense to show the credit has been refunded.” Refund your customer for a paid invoice in QuickBooks Online, read September 25, 2026.
Recorded AI proposals and tests
20 calls to claude-sonnet-5, made once on September 25, 2026 through Claude Code (2.1.282 (Claude Code)), with no tools and no other context. Each record keeps its input, raw output and time, and opens in its case. The page and the tests replay them; nothing calls a model when this page loads. 5 wrong proposals the model did not make were written for the tests and are marked as such.
109 of 109 tests passed when this page was built, on the same functions the page uses: tests/adversarial.test.ts (6), tests/closing.test.ts (7), tests/cutoff.test.ts (8), tests/duplicates.test.ts (6), tests/owner.test.ts (5), tests/payments.test.ts (7), tests/proof.test.ts (9), tests/records.test.ts (8), tests/reference.test.ts (37), tests/retry.test.ts (4), tests/sources.test.ts (9), tests/transfer.test.ts (3). The reference books were written and checked before the engine existed.
