7 Financial Warning Signs Before Working With a Company
Published 6 November 2026
None of these signs proves a company is in trouble — but each one is visible in public filings and each has preceded real failures often enough to deserve your attention.
1. Late or missing filings
Filing accounts late is a statutory breach with automatic penalties, yet companies do it surprisingly often — sometimes because the accounts are genuinely hard to finalise. A pattern of late filing, or a current overdue period, is one of the simplest and most reliable early warnings on the public register.
2. Negative shareholder equity
When liabilities exceed assets, equity goes negative: the company owes more than it owns. Companies can trade through this with shareholder support, but it means there is no buffer — any further loss deepens the hole, and creditors are relying on someone else's continued goodwill.
3. Sustained operating losses
One loss-making year happens to good companies. Three in a row is a pattern. Check whether losses are shrinking or growing, and whether turnover is falling at the same time — shrinking revenue plus persistent losses is a much worse combination than investment-driven losses on growing sales.
4. Margin collapse
A company holding turnover while its operating margin slides from 8% to 1% is working just as hard for almost nothing. In contracting especially, collapsing margins often mean work is being bought at unsustainable prices to keep cash coming in.
5. Overtrading — growth without capital
Rapid turnover growth sounds positive, but growth consumes cash: more work in progress, more debtors, more wages before payment arrives. When fast growth sits on thin equity, the company can be profitable on paper and still run out of cash. This is a classic failure mode in construction.
6. Frequent director or auditor changes
The register shows officer appointments and resignations. A revolving door of directors, or an auditor resignation where an audit is required, can signal disagreement behind the scenes. It is not proof of anything — but it is a reason to look closer.
7. A gap between story and filings
A company claiming rapid success while filing micro-entity accounts with minimal assets, or one whose registered details change repeatedly, is asking you to trust a story its filings do not support. The filings are the verifiable part — weight them accordingly.
What to do with a warning sign
Ask questions, tighten terms, reduce exposure, or walk away — proportionate to the risk you are taking on. And record what you saw: a documented decision with the evidence attached is worth far more than a memory if things go wrong later.
