Supplier Watch · weekly email

Know when a supplier is in trouble, before the invoice is

Upload the suppliers you pay or sell to. Each week one email lists only the ones that changed, the most serious first: dissolved, insolvent or struck off, VAT number invalid, unreliable VAT payer, accounts overdue, contract won, hiring freeze. Every line links to the official source, so a check takes a minute.

What goes in the digest

SignalRankSource and meaning
Dissolved, insolvent, in liquidation, struck offHighestBankruptcy, liquidation, restructuring, dissolution and proposals to strike off, as the national register records them (NO, FI, FR, CZ, GB).
VAT number invalidHighThe EU VIES service answers that the number is not valid; the SK list of cancelled VAT registrations.
Unreliable VAT payerHighThe official Czech list of unreliable payers (you can be liable for the VAT of an unreliable supplier) and the Slovak list of VAT deregistration grounds.
Accounts overdueMediumUK companies whose annual accounts are past the Companies House due date.
Public contract wonContextA supplier named as the winner of an EU TED or UK Find a Tender notice, with buyer, value and the notice link.
Hiring freezeContextOpen jobs falling against the supplier’s usual pace on its own career pages: an early sign of cost cutting.

A supplier that changed shows up once, with its findings in that order. A quiet week says so in one line. What we cannot see: a lost contract (we see awards, not terminations), and VAT status of countries whose authority publishes no list. The digest is a signal to check, not a credit rating.

Upload a list, see what matched

Send a CSV with one supplier per row: a website domain, a vat number with its country prefix, a registry id with its country, or a registered name with its country. Download the template. The answer is a match report: every row is matched, ambiguous (more than one company fits, so add a VAT number), not found, or withheld. Sole traders and natural persons are always withheld and never stored: the product follows companies only.

Questions

Where does the data come from?

National company registers (Norway, Finland, France, Czechia, the UK), the official Czech and Slovak VAT lists, the EU VIES VAT service, EU TED and UK Find a Tender award notices, and the suppliers’ own career pages. Every finding links to its source.

Is this a credit rating or a KYB check?

No. It is a change alert: it tells you something changed and where to verify it. It does not score creditworthiness, name owners or directors, or replace your own checks.

What about sole traders?

They are withheld at upload and never stored, because a sole trader’s registration is personal data. The match report counts them so you know how many rows were left out.

How are suppliers matched?

By website domain, VAT number or registry id against the company id table and the registers we hold. A row that fits more than one company is reported as ambiguous instead of guessed.

How do I stop it?

Every digest has a one-click unsubscribe link, and you can remove a supplier or the whole list at any time.
