Weak signals: spot a customer's deterioration before its next balance sheet
A published balance sheet describes the past. Legal notices, changes of directors, bank statements and late payments show what is happening now. Here are the signals to watch, and how to read them without a black box.
Why the balance sheet is not enough
The balance sheet remains essential to judge a company's financial structure. On its own, though, it leaves three blind spots.
A time lag
In France, annual accounts are approved within six months of the financial year-end, then filed with the commercial court registry. For a 31 December year-end, the latest available balance sheet can be close to eighteen months old when you read it.
Accounts that may be confidential
French micro-enterprises can ask for their accounts not to be made public, and small companies can keep their income statement confidential. For many very small businesses, the public balance sheet is missing or incomplete.
A snapshot at one date
A balance sheet describes the situation on closing day. It says nothing about today's cash position, a customer lost last month or a dispute under way.
The weak signals to watch
None is decisive on its own. Together, they often say more than the latest published balance sheet.
Legal notices
Published in the BODACC: repeated changes (registered office, share capital, business activity), sales of business assets and, of course, insolvency proceedings. Opened proceedings are no longer a weak signal, they are a fact; repeated changes deserve attention.
Directors
Frequent changes of manager or chairman, a recently appointed director, past mandates in companies that went through insolvency proceedings: elements to weigh against the rest of the file.
Bank statements
When the company shares them with you: rejected direct debits, a persistent overdraft, falling receipts, dependence on a few customers. This is often the most recent information you have.
Payment behaviour
Your own data matters: a customer who pays later and later, asks for extra time or splits payments is sending a signal its accounts do not show yet.
Financial trend
Look at several financial years rather than one: shrinking equity, rising debt, falling margins. A trend often says more than a single ratio.
Sector context
In a sector where business failures are rising, credit limits call for more caution. Official business failure statistics by sector provide that context.
Combining them without a black box
- 1
Collect
From the company's SIREN number, public legal and accounting data. Optionally, the balance sheets, tax returns and bank statements your customer sends you as PDFs.
- 2
Cross-check
A single signal is not an alert. The combination is what matters: a change of director does not weigh the same if receipts are falling at the same time.
- 3
Explain
The result must be readable: a 0-100 score and the factors that push it up or down, so the decision can be justified.
- 4
Decide and follow up
Your team sets acceptance and the credit limit, then follows key customers over time rather than once a year.

Frequently asked questions
Why is the balance sheet no longer enough to assess a B2B customer?
Because it arrives late and describes the past. In France, accounts are approved within six months of year-end and then filed: the latest available balance sheet can be close to eighteen months old. Many very small businesses do not publish their accounts at all. Weak signals complete that snapshot with more recent information.
Which weak signals should be watched first?
Legal notices (repeated changes, sales of business assets), changes of directors, bank statements when the customer shares them (rejected debits, persistent overdraft, falling receipts), how the customer's payment delays to you evolve, and the trend of its accounts over several years. Sector context helps calibrate the credit limit.
Is one weak signal enough to turn a customer down?
No. A single signal can have a trivial explanation. It is the combination of several signals, set against the accounts and the amount at stake, that justifies a decision: asking for a guarantee, lowering the credit limit, shortening payment terms or declining.
Can a company that does not publish its accounts be assessed?
Yes. The score then relies on legal data, directors and sector context, and becomes more precise if the company sends you its balance sheets or bank statements as PDFs, which RocketFin reads with OCR.
What does the GDPR say about automated decisions?
When a score concerns a natural person, for example a sole trader, Article 22 of the GDPR regulates decisions based solely on automated processing. An explainable score and a final decision taken by a person make it easier to comply.
