What is entity management?

A bank asks for a current group structure chart. You find three, and they disagree. One came from last year's audit pack, one from an adviser mid-acquisition, and one from a colleague who left in March.

That is what entity management exists to prevent, and the reason it is a statutory duty rather than an exercise in tidiness. Directors cannot discharge their duties over a group they cannot accurately describe, and the officers who maintain those records carry personal exposure when they are wrong.

Entity management is the work of maintaining the statutory record for every company, subsidiary, partnership, and branch in a group, and being able to evidence that record on demand. It covers who owns each entity and in what proportion, who its directors and officers are, where it is registered, which filings it owes and when, and how the entities relate to each other in the group structure.

The legal foundation matters here, because it sets the standard. The Companies Act 2006 requires a UK company to keep a register of members, and that register is the primary evidence of legal title to its shares. Under the Act, companies must also maintain information on people with significant control. The Economic Crime and Corporate Transparency Act 2023 has since moved some of this record-keeping toward Companies House centrally, while the register of members stays the company's own to keep. Failure to maintain the required registers is an offence committed by the company and by every officer in default.

So when a group asks whether it needs to take entity management seriously, the honest answer is that it has no choice. The only open question is whether you do it with a spreadsheet or a system.

Entity management software turns scattered entity records into a single structured system of record, then keeps that record current and evidenced. Understanding why that is worth paying for means looking first at how the scattered version fails.

Most groups do not lack entity information. Ownership details sit in a spreadsheet, director records sit in another, filing deadlines sit in someone's calendar or inbox, and share certificates sit in a shared drive nobody has tidied since the last acquisition. At one or two entities you can hold the whole picture in your head and reconcile the gaps by hand. That approach breaks down as the group grows, whether through acquisition, international expansion, or simply time, because records move between people and systems without a clean handover. Each move leaves behind a version that disagrees with the others, and eventually nobody can say which one governs.

The consequences are specific. A missed confirmation statement or a late set of accounts attracts a penalty, and persistent failure can put an entity on the path to strike-off. A share transfer recorded in one place and not the register of members leaves ownership open to challenge at exactly the moment it matters, in a sale or a refinancing. A bank that cannot reconcile your directors and signatories against its own file will not move money. Due diligence stalls while your team reconstructs the last decade of appointments from board minutes. None of these failures announce themselves in advance, which is what makes them expensive.

Ownership belongs in one structured, dated record that everything else reads from, rather than in prose or a chart. Shareholdings, share classes, transfer dates, and parent-subsidiary relationships work as connected fields, so a change entered once updates the group picture everywhere it appears. The alternative leaves a spreadsheet, a slide, and a PDF chart to drift apart, with no way of telling which came last.

Structure sits at the centre of more obligations than most people expect. Your register of members evidences title. Your PSC information feeds the public register and, through it, every counterparty running an ownership check. Where an overseas entity in your group holds UK property, the Register of Overseas Entities requires its beneficial owners to be registered, and without that registration you cannot register a disposition of the property at HM Land Registry, which can halt a sale outright. Sanctions work asks a harder version of the same question, because ownership and control must be traced through the chain rather than read off the top layer. Each of those obligations depends on one thing: knowing, today, who owns what.

Jurisdiction is where this gets genuinely difficult, and it is worth being straight about it. A group with entities in Luxembourg, Delaware, and Singapore faces different filing regimes, different registers, and different definitions of the same office. Board Intelligence's entity management system, IQ Entities, includes two-way Companies House sync, which keeps the UK internal record and the public register aligned in both directions rather than letting them drift between filings. Companies House covers the UK part of your estate only, so if most of your entities sit elsewhere, ask any vendor which registers they connect to and which they simply store data for.

Hold appointments as dated records against both the person and the entity, so one individual's full set of roles across the group is visible from a single place. A resignation is rarely a single event: it can trigger filings in several jurisdictions, leave a subsidiary short of a quorum, and invalidate bank mandates on the same afternoon.

Identity verification has raised the stakes on this. Since 18 November 2025, ECCTA has required UK directors and PSCs to verify their identity with Companies House, with personal codes flowing through appointments and confirmation statements. If you support a director who sits on fifteen boards in your group, you need to know all fifteen, along with which confirmation statement falls next. Reconstructing that list by hand each time is how deadlines get missed.

Attach every statutory obligation to an entity record and a named owner, with a date. The mechanism is ownership plus visibility: a deadline held in one person's memory leaves the organisation when they do, while a deadline held against a record does not.

Software that goes further and prepares or submits filings raises a question you should ask in the first demo. Two-way sync with a public register means software touching legal filings, so establish precisely where the approval gate sits: does a person approve each submission before it goes, or acknowledge it afterwards? Any vendor should be able to show you the authorisation step, the audit trail, and who is recorded as the presenter.

Company secretaries and governance teams are the primary users, alongside corporate service providers administering entities for clients, and the legal, tax, and finance teams that depend on accurate entity data.

If you are the company secretary, you use it because you carry personal responsibility for the accuracy of the statutory record and cannot verify it from memory across dozens of entities. You are also the person who fields the incoming questions from banks, auditors, and the board, usually at short notice and usually without the luxury of a week to reconcile first.

Worth knowing before you buy: the data migration is the hard part, not the software. Reconciling registers against Companies House, chasing missing certificates, and resolving contradictory versions of the same shareholding is manual work, and your team will do a meaningful share of it. Ask any vendor for a realistic timeline based on comparable groups, and treat a fast answer with suspicion.

Corporate service providers run into the same problem at greater volume. They administer entities for many separate clients, keep those records segregated and auditable, and carry direct commercial risk when a filing slips, because a client experiences that as a service failure. A provider managing several hundred entities across jurisdictions has no manual route to a reliable portfolio view.

Legal, tax, and finance teams rarely maintain the record themselves, and they inherit the consequences when it is wrong. They rely on it for transaction due diligence, transfer pricing, statutory accounts, consolidation, and dissolutions. Tax teams in particular need ownership percentages and incorporation dates that hold up under challenge, because the structure determines the treatment.

Entity management software governs the entity. Board management software governs the meeting. Entity management holds the statutory record of what a group owns and who is accountable for each part of it. Board management software, usually called a board portal, centralises the documents, permissions, and distribution a board needs to meet and decide.

The two overlap more than that distinction suggests, and the overlap is where teams get caught. Subsidiary minute books, written resolutions, and delegated authority matrices belong to both worlds. Subsidiary board minutes form part of the statutory record, not just the meeting archive, and a written resolution approving a share allotment is simultaneously a board document and the source for a register entry and a filing. A board portal handles version control, access permissions, secure collaboration, and offline access for board papers. On its own, it does not maintain ownership records or filings.

The practical test is whether a decision recorded in one system reaches the other. Groups that keep them connected close the gap between what the board approved and what the register says. Groups that do not usually discover the gap during diligence.

Companies House reform has made this a live agenda item rather than a background task. Under the Economic Crime and Corporate Transparency Act 2023, identity verification for directors and PSCs came into force on 18 November 2025, with existing officeholders working through the transition via their next confirmation statement. Further phases, covering those who present filings and the designation of a relevant officer where a legal entity is a PSC, are expected later. Alongside this, the registrar holds new powers to query information, reject filings, change an inappropriate registered office, and strike off companies formed on a false basis. A register that once absorbed inaccuracy now pushes back on it.

Group complexity has moved the other way. Acquisitions bring entities with inherited record-keeping habits and no clean handover. International expansion adds jurisdictions with different filing regimes. Dormant entities linger long after anyone remembers why they exist, each one carrying filing obligations, director appointments, and audit questions. That is why group simplification programmes keep reaching board agendas, and why they stall: you cannot rationalise a structure you cannot describe, and the first task in any simplification is establishing what you own and what each entity holds.

None of this makes entity management enjoyable work. It stays detailed, unglamorous, and dependent on people chasing colleagues for documents. What a system of record changes is where the effort goes: into resolving the record once, rather than reassembling it every time someone asks. For the company secretary who can produce the structure, the appointments, and the filing position on demand, that is the difference between defending the record and rebuilding it under time pressure.
