Never miss a confirmation statement again.
The quiet co-pilot for company secretarial work. CoSec Companion tracks every filing deadline across your client book — or your own — and tells you what's due, what's drafted, and what just needs your signature.
No card required. Set up in minutes, wherever your entities are registered.
Statutory work, finally legible.
Every deadline, one calendar
Confirmation statements, accounts, corporation tax returns, PSC updates, AGM dates — all in a single roll-up across your book or your firm.
Generated, not guessed
Filing dates are calculated from incorporation, ARD, and rule chains — the same engine HMRC and Companies House use, applied automatically the moment an entity is added.
Quiet by design
No bright dashboards or noisy notifications. A list of what's due, what's drafted, and what just needs your signature.
A roll-up calendar across every client.
One client may be a single Ltd or a parent with subsidiaries. Group entities under a client, drill in by client or entity, and never search across spreadsheets again. Filing focus: CS01, CT600, statutory accounts, AP01/TM01.
The wider cosec remit, in one place.
Confirmation statements, AP01/TM01/CH01, AD01, PSC01/07, AGM, share allotments, charges. Designed for the part-time or stretched company secretary in a single firm or small group. No client gate — your entities, listed directly.
