A spreadsheet kept by the practice
Your own list of clients, due dates and notes. It costs nothing to start and fits the way you work, but it only knows what someone types into it, and only from the day they do.

Three ways a practice keeps track of its client companies on Companies House. Two of them are free. This page says what each one does, where the free options are enough and what CompanyGuard adds, with a source for every claim about a Companies House service.

The options
Most practices start with the first two. Each one suits a different size of portfolio and team.
Your own list of clients, due dates and notes. It costs nothing to start and fits the way you work, but it only knows what someone types into it, and only from the day they do.
A free Companies House service. You sign in, choose "Follow this company" on each company, and get an email as soon as Companies House accepts a filing for it.[1]
Paid monitoring and casework for practices: deadlines and changes for the whole portfolio in one list, an owner and a decision for each case, and a check against newer evidence before a case closes. Starter costs £29 for up to 300 monitored companies, Growth costs £59 for up to 750, and Scale costs £99 for up to 2,000.
Side by side
The Companies House column uses only what Companies House's own guidance says about the follow service. "Not described in its guidance" means the guidance does not mention it.

Free options
You may not need CompanyGuard. These are the cases where the free options already do the job.
Follow alerts tell you when something is filed, the register shows each company's next due dates, and a spreadsheet holds your notes. For a short list looked after by one person, that can be all you need.[1]
A follow alert arrives as soon as Companies House accepts a filing. CompanyGuard checks each company about every 24 hours, so the alert is faster.[1]
Companies House also runs a free email reminder service for accounts and confirmation statements. Up to 4 people, including an agent, can receive the reminders for each company.[2]
When it grows
Once the portfolio is longer than one person can watch, or several people share the work, a notice that something was filed is only the start.
Deadlines, changes and sources that could not be read appear in one list, ordered by severity, instead of one email per filing.
Each case is assigned to a colleague, with the next review date and the decision and its reason kept in its history.
A case closes as verified only when newer Companies House evidence supports it, and a print-friendly dossier keeps the sources, owners and decisions.
