Why Companies House filings matter, but cannot be the live transfer source
Accounts are vital for checking revenue, wages and historic PSR. They are too delayed to track live transfer-window spending on their own.

Revenue, wages, annual transfer-fee cost, profit/loss and owner funding.
Accounts arrive after the transfer activity has happened.
Filings check and recalibrate prior estimates.
The quick read
Companies House filings are one of the most important sources in football finance. They show actual accounts, not transfer-window rumour.
But filings arrive after the fact. That makes them excellent for reconciliation and calibration, but not enough for a live summer transfer-window product.
What filings help with
Filings can confirm revenue, wage bill, player-registration costs, profit or loss, owner funding and balance-sheet movement.
Those values help PSRwatch check historic seasons and improve future assumptions.
What filings do not solve
They do not tell you, in real time, how a new signing changes the current summer spending-room picture. For that, PSRwatch needs transfer movement, contract assumptions and wage estimates.
What this means
Companies House is the accounting anchor. Transfer and wage feeds are the live movement layer. PSRwatch combines them, validates the result and keeps the last good snapshot if a source breaks.
