What's compared, every time

Side-by-side comparison

Turnover, profit, assets, liabilities, and employee count shown for both filings at once.

Material change flags

Changes exceeding £1M absolute or 10% relative are highlighted, sorted by magnitude.

AI executive summary

A concise, plain-language read of what shifted and what it likely means, generated from the actual deltas.

Direction & magnitude

Every change is shown with a clear increase/decrease arrow and percentage, sorted by significance.

Nine tracked metrics

Turnover, operating profit, profit before/after tax, total & net assets, liabilities, net current assets, and headcount.

Automatic, not manual

No need to pull two PDFs and compare line by line — the comparison happens the moment you open the page.

Who uses it

Investor Monitoring

Catching deterioration in a held position early

An investor holding a stake in a private company gets an automatic read of what changed the moment new accounts are filed — spotting a liabilities increase or margin compression without manually re-reading the full filing each year.

Year-on-year change caught immediately, not discovered months later.
Audit & Assurance

Identifying areas warranting closer review

An auditor uses Document Delta as a first-pass scan across a portfolio of client companies, directing attention to the accounts with the most material year-on-year movement rather than reviewing every line of every filing equally.

Review effort focused where the real change actually happened.
Non-Executive Director

Preparing for a board meeting with the real changes in hand

Ahead of a board meeting, a NED reviews Document Delta for each company they sit on the board of, arriving with specific, informed questions about the actual material movements rather than a generic review of the latest accounts.

Board-level scrutiny grounded in the real year-on-year picture.

What counts as a material change?

A change is flagged as material if it exceeds a defined absolute or percentage threshold — currently over £1M absolute change or over 10% relative change on a given metric.

Does the AI summary replace reading the actual figures?

No — the summary sits alongside the full side-by-side figures for both filings, so you can verify the narrative against the underlying numbers directly.

What happens if a company only has one filing on record?

Document Delta requires at least two filings to compare. With only one on record, it will clearly state there isn't enough history yet, rather than showing a misleading comparison.

Which metrics are compared?

Turnover, operating profit, profit before and after tax, total assets, net assets, current liabilities, net current assets, and employee count.
