Boundary and sources
This runway strip works only on the monthly cash figures you paste you paste. It does not produce statutory accounts, does not forecast revenue you have not invoiced, and does not advise on insolvency. The figures describe what you supplied, not what is true in the world. Confirm anything you plan to act on with your accountant before changing payment terms or drawing on a facility before you rely on it.
- Every figure comes from the monthly cash figures you paste you paste; nothing is looked up, scraped or asserted as verified.
- Method: closing balance = previous balance + in − out, with the floor rule drawn across and the crossing month marked
- Sample values are labelled samples — illustrative by design, not your data and not a quotation of any organisation's policy.
