Why this matters to you as a creditor
When one of your customers has a petition advertised against it, your position changes from waiting for payment to competing for what remains. The single most useful thing you can do is spot the petition early, register your interest with the liquidator the moment one is appointed, and respond to every proof-of-debt request.
Black Flag Alert tracks winding-up petitions from The Gazette as they appear. An active petition forces the risk rating to 10 (Distressed), whatever the filed accounts say, because no set of accounts outranks a live court process.
Watchlists notify you the moment a petition, judgment or insolvency notice appears against a company you are tracking.
