A firm rarely loses its fees because a client refuses to pay. It loses them because nobody chased. The invoice raised in March resurfaces in June, the retainer agreed when the matter opened was topped up once while the case doubled in size, and the payment plan a client accepted in February stopped at the third instalment with nobody noticing. Meanwhile the work carries on.
On top of that sits a discomfort specific to the profession: writing to a client about money while you are defending their interests never feels right, least of all when the case is going badly. So the chaser waits, and when it finally goes out it is late and blunt, which reopens the argument over months of work already done. An AIOS keeps the balance current, prepares the chaser while it still reads as routine, in the tone that suits each client, and flags the situations where the call is yours.
The problem
- The real outstanding balance is nowhere visible in full: it sits across the practice management software, the bank account, the fee agreement and one partner's memory
- The retainer agreed at the outset is called once, then never adjusted as the matter grows
- The chaser gets postponed out of awkwardness: writing to a client mid-litigation about an invoice is never the right moment
- When it finally goes out it is late and abrupt, and the discussion reopens over months of work already delivered
How the AIOS handles it
It keeps the outstanding balance current, matter by matter
Invoices raised, sums received, retainers called and paid, payment plans running: the AIOS consolidates all of it from your exports and statements and keeps a live picture. Who owes what, for how many days, on which matter, at what stage of the proceedings and under which fee agreement. You stop rediscovering the position at a cash-flow meeting.
It chases while a chaser still reads as routine
A courteous reminder a few days after the due date, with the invoice and a breakdown of the work attached, almost always settles itself. It is the chaser three months later that creates the dispute. The AIOS applies the rhythm you set, plain reminder, then firmer chaser, then an offer of instalments, and it takes the state of the matter into account: it will not chase the day after an adverse decision or on the eve of a hearing.
It matches the tone to the relationship
A corporate client of six years with an accounts department is not chased the way a private client in the middle of a divorce is. For the company, a factual message to the right contact with the invoice reference and whatever accounts payable needs. For the private client, a message that leads with the work delivered and offers a schedule rather than a formal demand. In both cases, your signature and your phrasing.
It anticipates top-ups and overruns
When a matter consumes more than the retainer covers, it tells you while the gap is still small, with a breakdown of the work already done and a draft request for a further payment on account that follows your fee agreement. Fixed-fee matters get the same treatment: it spots requests falling outside the agreed scope so you can say so at the moment it happens, not at the end.
A concrete example
Where do we stand on unpaid fees?
Forty-one thousand euros outstanding across eleven matters, twenty-eight thousand of which is under thirty days, so nothing alarming. Three situations need your view. Tavernier has two invoices open for seventy days and has stopped answering chasers sent to their accounts address; they changed finance director last month, so I would rather reopen contact with the new one than send an identical third reminder. On Vasseur the payment plan stopped at the third instalment out of six with no explanation; that client has paid on time until now, so a plain reminder will probably do. And on Lemoine the matter has run eleven hours beyond the retainer, with an expert report just ordered: the request for a further payment on account is drafted under your fee agreement, itemised, waiting for your approval. For the other eight matters the reminders are ready and go out tomorrow morning unless you say otherwise.
