The Paper Trail Before the Purchase Order: A Companies House Check for UK Software Buyers

You have sat through the demo, the pricing call and the security questionnaire. The tool looks tidy, the sales team is friendly and the annual invoice is just about justifiable. Before you send the purchase order, though, there is one inexpensive habit worth adding to your buying routine: look the supplier up on Companies House.

It is free, it takes about twenty minutes, and it will not tell you whether the software is brilliant. What it will do is give you a factual picture of the UK company you are about to rely on — and sometimes that picture raises a question you would rather ask now than after your team has moved its workflows into the product.

Start with the legal entity, not the logo

The first step is boring and essential: find the legal name and company number. Do not simply search the trading name from the website. Check the contract, the terms and conditions, the invoice or the privacy notice for the registered company name. Software brands often sit under a parent company, a group subsidiary or a name that looks nothing like the product.

Once you have the company number, search Companies House and check the status. An active company is the baseline. Also note the incorporation date. A supplier that has been trading for six months is not automatically a bad bet, but it does change the risk conversation. Young companies can be excellent; they can also be one funding round away from a change of direction.

While you are there, look at previous names. A recent rebrand is not suspicious on its own — plenty of software companies rename products or whole businesses. But if the company has changed names more than once in a short period, it is reasonable to ask why. The filing history under the old names may tell you more than the glossy current website.

Read the filing history like a rhythm section

Companies House keeps a filing history, and for a UK software buyer the useful signal is not usually one dramatic document. It is the rhythm. Has the company filed its confirmation statement on time? Are accounts appearing when they should? Repeated late filings are worth noticing, especially if they are combined with a small team, a sudden change of address or a product that seems to have gone quiet.

Accounts are the other half of this. Small companies often file micro-entity accounts, which do not include much detail. That is normal and not a warning sign by itself. Dormant accounts are different: if a company is filing as dormant while actively selling software subscriptions, ask how the trading entity is structured. There may be a perfectly sensible group arrangement behind it, but you want to understand it before you sign.

Look at the accounts notes and the balance sheet rather than treating the document as a pass-or-fail test. A tiny balance sheet does not prove the company is about to fold, and a healthy-looking one does not prove the product will still exist in three years. The point is to build a picture, not to play auditor.

Ownership, directors and charges

The people section matters too. Check the persons with significant control (PSC) and the directors. Frequent director changes can suggest instability, though early-stage companies often rotate roles. Opaque ownership through offshore entities is not illegal, but it is a fair prompt to ask who ultimately owns the supplier and who would make decisions if the company were sold or restructured.

The charges register is often overlooked. A charge can mean a lender has a claim over the company's assets. That is not automatically bad — plenty of growing businesses borrow — but it is relevant context if you are committing to a multi-year contract. The filing history may also show insolvency-related events, administration, striking-off proposals or other corporate changes. Read the documents rather than relying on a headline.

What the record cannot prove

This is the important bit: Companies House is a paper trail, not a warranty. A clean filing record does not guarantee good support, sensible security, a reliable roadmap or fair renewal pricing. A large, well-filed company can sunset a product with very little notice. A small company with modest accounts can be the most responsive supplier you have ever worked with.

Also remember that Companies House covers UK registered entities. If your supplier is overseas, or if the contracting entity is an LLP or partnership, the same search may not give you the whole picture. Pair the check with the contract, the security review and a straightforward conversation with the supplier.

Make the paper trail part of an exit plan

A Companies House check is most useful when it sits alongside a sensible exit plan. Before you commit, know how you would get your data out, how much notice you need to give, whether there is any escrow or transition assistance, and who inside your team would own the switch if the supplier changed direction. If the filing history raises a question, ask it directly and keep the answer with your procurement notes.

For a small UK team, a simple routine works well: confirm the legal entity and company number; check status, incorporation date and previous names; scan the last few years of filing history; look at the accounts type and any charges; review the PSC and directors; then write down two or three questions for the supplier. If the answers are clear, proceed with your eyes open. If they are vague, you have learned something useful before the invoice arrives.

SealSoft's view is simple: due diligence should be proportionate, not theatrical. Companies House gives UK buyers a free, factual starting point. Use it to ask better questions — just do not mistake the paper trail for a guarantee.
