Worked problems
Real jobs, written as patterns: no client, no sector detail that could identify one, and no figures. All from accounting-data work so far.
- 01When a coding rule silently miscodes a year of transactionsA short text rule intended for one kind of bank charge matched the same letters inside an unrelated word, miscoding a large class of transactions to a plausible account.Accounting data
- 02Duplicate expenses when receipts arrive by photo and by emailReceipts photographed on site were restating invoices already filed as PDFs. The pairs shared no file characteristics, so no review of the folder could surface them.Accounting data
- 03Card paydowns double-counting a year of client spendingPayments moving money between an entity own accounts were recorded as expenses alongside the transactions they settled, double-counting a year of spending.Accounting data
- 04Reconciliation out by exactly double? That is a sign errorA reconciliation was out by precisely double the value of a set of supplier refunds, because an absolute-value conversion had moved each of them from negative to positive.Accounting data
- 05The statement set that looks complete and is missing a monthA statement set held the expected number of files and was still missing a month: one was misnamed by a year, another duplicated a period already present.Accounting data
- 06Why invoice dates land in the wrong periodNumeric dates on supplier documents were ambiguous between two conventions. Assuming one silently moved documents across period boundaries in both directions.Accounting data
- 07Quotes and payment confirmations inflating client cost totalsA folder assembled over months contained payment confirmations, quotes and a closing statement — each individually legitimate, each carrying figures that entered the totals.Accounting data
- 08Why a single OCR pass cannot tell you when it is wrongOne engine read a figure an order of magnitude away from another, from the identical image, with no indication of uncertainty from either.Accounting data
- 09The balanced report that is completely invertedA report omitted a column on rows where it had no value, so reading cells by position moved every credit into the debit column — and the report still footed correctly.Accounting data
