概覽

AI 產生的概覽

讓助理驗證英國微型實體公司資產負債表、換算申報數字並查詢公司登記與申報期限。

可以做什麼
可從原始數字推導並驗證小型公司(英國微型實體)資產負債表,並把分類後的銀行對帳單彙總轉成申報數字。也能依公司登記號查詢公開登記資料、搜尋公司、讀取上年度已申報數字,並計算延遲申報罰款與延期申請期限。另可儲存、列出與刪除申報草稿,追蹤公司申報期限,並以白話解釋數字。
適用情境
當您要為英國微型實體公司編製並檢查資產負債表、把銀行對帳單分類彙總轉成申報數字、查詢公司登記資料,或評估延遲申報罰款與延期申請時使用。
執行需求
遠端端點,無需本機執行環境。輸入以主要貨幣單位表示。部分功能依賴外部公開登記(GB 為 Companies House、AU 為 ABN Lookup)與模型服務,且受每日配額限制;可用 server_status 查看目前可用的整合與剩餘配額。
安裝前請注意
save_filing 會寫入使用者帳戶,delete_filing 會永久刪除且無法復原,呼叫前應先確認。track_company_deadlines 實際發送的通路可能為空,需讀取回覆確認。explain_accounts 會把推導後的報表送給模型(不含公司名稱或編號),categorise_transactions 只應傳送交易描述字串。部分工具受配額計費。

check_accounts

Check Accounts

Derive a small-company balance sheet (micro-entity, in UK terms) from raw figures and validate it. Returns the derived sheet for the current and prior year, the figures the authority would reject (negatives where it wants a positive, share capital left at nil), and whether they are complete enough to hand to a filing product. It does NOT check that the sheet balances and cannot: retained earnings is derived as the balancing figure, so both sides always agree. Do not tell anybody their sheet was checked for internal consistency. Free and instant: call it after every change to the figures. All money in major units (pounds not pence, dollars not cents). Pass lastFiledAs from lookup_company and it also warns when figures showing activity are about to be filed dormant again.

輸入參數figures必填lastFiledAsjurisdiction必填

dormant_figures

Dormant Figures

The complete set of figures for a dormant company: share capital, the matching cash, and zeros everywhere else. The register says when the last accounts were filed dormant, and for those companies this collapses the whole form to one call. Amounts in major units.

輸入參數shareCapital必填

totals_to_figures

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. Totals are signed major units per category code; get codes from categorise_transactions.

輸入參數totals必填

late_filing_penalty

Late Filing Penalty

What missing a Companies House accounts deadline costs. Given the due date, returns days remaining or overdue, the penalty band already incurred, and what the next band costs, the number that makes someone act today. UK private companies only.

輸入參數accountsDue必填

list_jurisdictions

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. Call this first when unsure.

無需輸入參數。

sample_accounts

Sample Accounts

A real worked example: nil turnover, a director loan, a near-empty bank account, the simplest accounts the UK regime permits. Use it to demonstrate check_accounts or as a template for a first-year company. Amounts in major units.

無需輸入參數。

lookup_company

Lookup Company

Look a company up on its public register (Companies House for GB, ABN Lookup for AU) by its registered number. Returns the full public record: name, status, registered office, officers, SIC codes, accounting period, plus both filing deadlines with days remaining and the late-filing penalty already incurred if overdue. Rate limited and quota-charged; cached results are free. Find the number first with search_companies.

輸入參數jurisdiction必填companyNumber必填

search_companies

Search Companies

Find a company by name on its public register and get back its registered number, status and address. This is how you reach lookup_company when the person only knows the name. Free of the daily quota; lightly rate limited.

輸入參數query必填jurisdiction必填

get_prior_year_figures

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. Saves typing seven numbers from a PDF and gets the comparatives exactly as filed. GB only, and only when the last accounts were filed digitally. Quota-charged; cached results are free.

輸入參數companyNumber必填

explain_accounts

Explain Accounts

A plain-English reading of a set of figures, written for a director who is not an accountant: what the derived balance sheet says about the company and anything that needs attention before filing. Only the derived sheet is sent to the model, no company name or number. Quota-charged; identical figures are answered from cache free.

輸入參數figures必填jurisdiction必填

categorise_transactions

Categorise Transactions

Categorise bank-statement transaction descriptions into the fixed vocabulary this product maps to balance sheet lines (sales, software, owner-in, …). Send description strings only, never amounts or dates. Sum the amounts per returned category yourself, then call totals_to_figures. One statement import is one quota unit; previously seen descriptions are answered from a shared cache free.

輸入參數tradingType必填descriptions必填

check_filing_extension

Check Filing Extension

Whether a company can still apply to its registrar for more time to file, how many days are left to apply, and what being late costs if that window is missed. This is usually the most useful thing to tell somebody who has just found a deadline: applying is free, takes about 15 minutes, and has to be done BEFORE the deadline it extends, so the option expires on the same day the penalty starts. Returns nextAction first. It PREPARES an application and can never submit one: the application is made by a director on the registrar’s own service, which this tool links to. It does not file accounts. Give a company number to read the deadline off the register (quota-charged, cached results free), or give the dates yourself and it costs nothing.

輸入參數todayfiling必填periodEndjurisdiction必填companyNumberfilingDeadlinealreadyExtended必填

draft_extension_reason

Draft Extension Reason

Turn a short factual account of what went wrong into the reason text for an application for more time to file accounts, framed in the terms the registrar actually applies. It uses only the facts you give it: it will not invent circumstances, and where something is missing it leaves a bracketed placeholder rather than filling it in. The person must check every sentence before using it, because they are certifying it to the registrar. Ask them what happened, do not supply it yourself. This tool does not submit the application and does not file accounts. Quota-charged as an explanation; identical input is answered from cache free.

list_saved_filings

List Saved Filings

The user's saved filings, most recently touched first, with every figure in major units. This is the same list the website dashboard shows. Start here when asked about "my accounts" or "my company".

無需輸入參數。

save_filing

Save Filing

Save a set of figures to the user's account, or update a saved one by passing its id from list_saved_filings. Figures in major units. The filing is saved even when validation finds problems, because a work in progress is worth keeping, and the problems come back in the response so you can raise them.

輸入參數idlabelfigures必填identifiersjurisdiction必填categoryTotals

delete_filing

Delete Filing

Delete one saved filing by id, permanently. Confirm with the person before calling this; there is no undo and no trash.

輸入參數id必填

track_company_deadlines

Track Company Deadlines

Watch a company by its register number and get reminded before its filing deadlines. Which channels are actually available depends on the server: the reply reports what will really be sent, and it can be nothing at all, so read it rather than assuming. No saved filing is needed: this is for the deadline itself, which matters months before any figures exist. Reminders go out on a ladder of days before the deadline (default 90, 60, 30, 14, 7, 1), and each one states the company, the deadline, the date, the days remaining and the penalty for missing it. Calling this again updates the settings and un-mutes a company that was untracked.

輸入參數push必填email必填jurisdiction必填companyNumber必填remindDaysBefore

list_tracked_companies

List Tracked Companies

Every company this user gets deadline reminders about, including the ones implied by their saved filings. Shows the next accounts deadline and days remaining where a register record is already cached. Free: this never contacts a register.

無需輸入參數。

untrack_company_deadlines

Untrack Company Deadlines

Stop sending deadline reminders about a company. This mutes rather than forgets, which is the only thing that holds: a company implied by a saved filing would otherwise be re-added by the next scan. track_company_deadlines un-mutes it again.

輸入參數jurisdiction必填companyNumber必填

server_status

Server Status

What this deployment can actually do right now: which integrations are configured, whether your token is valid, and how much of each daily quota you have left. Call it when a tool refuses and you want to know whether the feature is off or used up.

無需輸入參數。
