让助手校验英国微型实体公司资产负债表、换算申报数字并查询公司登记与申报期限。

可以做什么
可根据原始数字推导并校验小型公司(英国微型实体)资产负债表,并把分类后的银行对账单汇总转换为申报数字。还能按公司登记号查询公开登记信息、搜索公司、读取上一年度已申报数字,并计算逾期申报罚款与延期申请期限。另可保存、列出与删除申报草稿,跟踪公司申报期限,并用通俗语言解释数字。
适用场景
适用于为英国微型实体公司编制并校验资产负债表、把银行对账单分类汇总转换为申报数字、查询公司登记信息,或评估逾期申报罚款与延期申请时。
运行要求
远程端点,无需本地运行环境。金额以主要货币单位表示。部分功能依赖外部公开登记(GB 为 Companies House、AU 为 ABN Lookup)与模型服务,并受每日配额限制;可用 server_status 查看当前可用的集成与剩余配额。
安装前请注意
save_filing 会写入用户账户,delete_filing 会永久删除且无法撤销,调用前应先确认。track_company_deadlines 实际发送的渠道可能为空,需读取回复确认。explain_accounts 会把推导后的报表发送给模型(不含公司名称或编号),categorise_transactions 只应发送交易描述字符串。部分工具按配额计费。

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.

输入参数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.

输入参数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.

输入参数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.

输入参数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.

无需输入参数。

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.

无需输入参数。

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.

输入参数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.

输入参数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.

输入参数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.

输入参数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.

输入参数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.

输入参数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".

无需输入参数。

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.

输入参数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.

输入参数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.

输入参数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.

无需输入参数。

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.

输入参数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.
