check_accounts — Derive a small-company balance sheet (micro-entity, in UK terms) from raw figures and validate it.
dormant_figures — The complete set of figures for a dormant company: share capital, the matching cash, and zeros everywhere else.
totals_to_figures — Turn categorised bank-statement totals into balance sheet figures, applying the rules that stop an import lying: only income categories reach turnover, only expense categories reach operating costs, and the owner topping up the account is never sales.
late_filing_penalty — What missing a Companies House accounts deadline costs.
list_jurisdictions — The countries this server knows about and what it can actually do in each: which have a real accounts engine, which registers can be searched or looked up, the currency, and the identifiers each jurisdiction files under.
sample_accounts — A real worked example: nil turnover, a director loan, a near-empty bank account, the simplest accounts the UK regime permits.
lookup_company — Look a company up on its public register (Companies House for GB, ABN Lookup for AU) by its registered number.
get_prior_year_figures — Read last year's figures out of the company's last filed accounts at Companies House, ready to drop into the *Prior fields of check_accounts or save_filing.
