Take a firm of ten fee earners and a bill of four thousand eight hundred pounds delivered in February on a commercial dispute. By August the matter is still live, the fee earner has recorded another eleven thousand pounds of time on it, and nobody has spoken to the client about the February bill. It appears on the aged debtor report every month, and the reason it sits there is not that the client refuses to pay. Nobody has asked.
The cause is structural rather than personal. The aged debtor report belongs to the accounts team, who know the figure, the date of delivery and the age of the balance. What they do not know is the matter. They cannot tell whether the client disputes the work, whether a settlement is close, or whether the fee earner agreed to hold off until completion, so the chase goes out as a standard letter or does not go out at all. The fee earner who knows all of that never sees the report, because it reaches the partners in a monthly finance pack read by the people managing the firm rather than the people managing the file. The debt then ages in the space between the two, quietly, because neither side treats it as theirs.
Why the conversation keeps getting deferred
Even when the fee earner does see the balance, asking for it is awkward in a way that unbilled work is not. You are still acting, you will speak to this client about their case tomorrow, and you would rather that call be about the case. So the conversation waits for a better moment, and the better moment never arrives, because every week the balance grows and the request gets harder to make politely. A firm that raises four thousand eight hundred pounds at eight weeks is having a routine conversation. The same firm raising sixteen thousand at six months is having an argument, and the client hears an accusation in it.
There is a simpler problem sitting behind that one, and firms miss it often. Money held on account can be applied against a bill already delivered, and plenty of matters carry an unpaid bill and a client account balance at once, sometimes a balance that would clear the bill outright. Nobody checks, because the ledger and the debtor report are read by different people for different reasons. Before anyone drafts a chasing letter, ask whether the money is already in the firm's hands.
The rule worth adopting is a written one. Past an age the firm sets for itself, whether sixty days or ninety, no further chargeable work goes on a matter carrying an unpaid delivered bill unless a partner records in writing that it continues and why. The alternative is drift, and drift is what turned the February bill into a balance nobody wants to raise. That rule has to respect the position you are in, because a firm cannot drop a client for not paying. It may stop acting only where it has good reason and gives reasonable notice, so carrying on has to be a decision rather than a silence. A statutory rule pulls the same way, since a firm cannot begin proceedings on a bill until a month has passed since delivery, and a debt left to age also delays the point at which the firm has any remedy.
All of this rests on terms agreed at the outset. The SRA expects a client to be given the best possible information about the likely overall cost at the start and again when things change, and your terms on payment and interest belong in the client care letter written then. A firm that never mentioned interest cannot introduce it in the middle of an argument.
Where the ledger meets the matter
The Bracton AI Assistant plugs into the case management or CRM system a firm already runs, being LEAP, Clio, Proclaim or another, and reads every live matter overnight rather than the single file a fee earner has open. It reads the ledger against the matter, so an unpaid bill past the age the firm sets arrives on the morning list beside the matter it belongs to, with the client balance that would clear it, the time recorded since the bill went out, and a drafted chasing letter. A qualified fee earner approves or amends everything before it leaves the firm, and the assistant files its output inside the firm's own system rather than writing to a client itself. It is built into Bracton, the case and client management platform, and sold on its own to a firm contracted elsewhere.
Your own numbers teach more than anything written about somebody else's. Run the aged debtor report, take the five oldest balances on live matters, and read each client ledger for money on account and time recorded since delivery. That exercise starts on your own records, which is where we start too, so if you want an outside read on how those ledgers stand against the SRA Accounts Rules, book a client account review.
