By the second week of December the mail goes quiet, and Corinne has never worked out what to do with it.
Her practice is seven people, about four hundred individual returns and sixty business ones behind them. From the middle of February to the middle of April her own mailbox takes three hundred messages a day. In the flat months it takes a hundred and ten, and in December it drops under that, because the extensions were done in October, most of the year-end work is sitting with the bookkeepers, and for roughly three weeks nobody outside the firm is waiting on her inside the week.
She has always used those weeks to rest, which is fair, and to tidy, which feels like getting ready and is not. Then the second week of January arrives, and every arrangement the firm runs for the next four months turns out to be whatever arrangement it happened to have on the last working day of December.
That is the subject here, and it is not about working harder in March. It is about what one practice can settle in the only weeks of the year when settling something is free, and about which of those things are worth the December it costs.
Whether to let software read client mail at all is a separate decision, and an earlier one. Corinne made it in the autumn, on the six questions in why you’re right to be careful with AI, and this series starts on the other side of it. What is left is a question of timing.
The four weeks with slack in them
December is not empty, and it is worth being accurate about that before treating it as spare capacity.
The clients with a December year end are closing their books, which is its own body of work with its own inputs that cannot be recovered in March, and year-end close is where that job lives. The fourth estimate falls due in the middle of January, so the reminders go out now and the silence that follows them starts now, which quarterly estimate reminders takes apart properly. Engagement letters are going out or about to. None of that is nothing.
What December has that no other month has is slack of a specific kind. Not free hours. Nobody outside the firm is waiting on you within the week. Every one of the December jobs has a date, and none of those dates is tomorrow, so a morning spent on something that produces nothing today costs nothing today either.
Which matters because of an asymmetry in when a change gets made. A change to how the mailbox works, made in the first half of December, has six weeks to settle, be wrong twice, and be corrected before anything depends on it. The identical change made on the tenth of February is a second emergency laid on top of the first, and it will be abandoned by the fourteenth, and the firm will conclude that the thing did not work when what happened is that it was started in the wrong month.
The problem with December is not that firms do not know this. It is that nothing in December forces anything. Every other decision a practice makes gets made because a date arrives and makes it. These weeks have no such date, so the whole month is available to be spent on the small satisfying work of clearing a screen, and the screen clears, and January is unchanged.
So the December discipline is a strange one. It is treating the absence of a deadline as the reason to act rather than the reason it can wait.
What last season left in your sent items
Start with what went wrong last year, and do not start from memory.
Memory of a season is unreliable in a particular direction. What you retain is the one disaster, told as a story, usually with a villain in it. What you do not retain is the eleven small ones, each of which cost twenty minutes and a little credibility and none of which was interesting enough to survive April.
The record is sitting in your mail, and it is written in your own hand. Corinne ran four searches on her sent items for last January through last April, looking for the phrases she uses when she has been slow: apologies for the delay, only just seeing this, resending, thanks for your patience. Thirty-one messages came back. Then she ran the reverse on what she received, for the phrases clients use when they are chasing: following up, checking in, second time, did you get my.
The second list is the better one. Thirty-one apologies tell you what you noticed. What a client bothered to chase tells you what actually mattered to somebody paying you, which is a different and more expensive list, and it is shorter, because people only chase twice for things they care about.
Then look at the shape rather than the count. Corinne’s thirty-one were not spread across four months. Nineteen of them fell inside three weeks in the middle of March, which tells her about capacity. Seven of the remainder went to the same two clients, in weeks that were not busy, which tells her about something else entirely, because those two send everything as a forwarded chain from their bookkeeper with nothing written above the attachments, and a message with no words in it does not look like a message that needs anything.
Those two findings want opposite responses, and telling them apart is most of the value of the exercise. A cluster in mid-March is volume, and volume is not fixed by attention. A pattern attached to one sender or one kind of message is a hole in how the mailbox surfaces things, and it will be there again in June when there is no season to blame. The general case, which is that a flat list sorts on how loudly a message was written rather than on what it will cost you, is worked through in email overload, and the reason it bites hardest in a practice is that a client’s mail is only ever readable against the list of what that client still owes you, which running the firm inbox sets out.
An hour on this, once, in December. It is the only hour of the year when the evidence is complete and nothing is currently on fire.
The list of names is a year out of date
Every practice has a list of people it cannot afford to miss. In most practices it lives in one person’s head and was last revised by accident.
A year has passed since it was accurate. Clients have left. Clients have arrived, and the ones who arrived in November are the ones with no history in the mailbox at all, which is exactly the condition that makes a message look unimportant. A long-standing client changed bookkeepers in August and the new one has written to you twice. The bank moved your relationship manager. A client hired a controller, and from January that controller is the person who answers, not the owner you have dealt with for nine years.
Then there is a category that only exists between January and April, and it is the one nobody writes down. A payroll bureau that sends the year-end reports from an address no human reads. A brokerage’s document team. The portal notification from a state revenue department, which arrives once, looks like every other automated notice, and is the only warning you get. None of these people are your clients. Several of them decide whether a return can be finished, and not one of them has a history in your mailbox that would suggest they matter.
The useful move is to build the list from the engagement list rather than from recollection. Whoever you have accepted for the season is on it, and then, for each of them, whoever else writes on their behalf. That second half is where the misses live, because a firm’s instincts are trained on client names and half the mail that decides a return comes from somebody who is not the client.
What naming people in advance does, and the honest limits of it, is covered in VIP mail that never gets buried. The sitting-down-and-doing-it version, including the ten minutes on the contact list that turns the exercise into something a machine can use, is day four of a first fortnight. What belongs to December is only that the list is stale, the staleness is invisible, and January is when it costs.
The mail you are about to cause
Here is the part practices consistently miss, and it is the most predictable inbox event of the entire year, because you schedule it yourself.
Somewhere between the middle of December and the middle of January the firm sends its season mail out to the whole base at once. The organizer. The engagement letter. The fee change, if there is one. The portal invitation. For Corinne that is four hundred and sixty near-identical messages inside a fortnight, and it is the single largest thing her firm does to its own mailbox all year.
What comes back is not documents. It comes back in three shapes, and they are not the same job.
Some of it is questions. About the fee, about whether they still need to fill any of this in given last year, about something on the prior return they have been meaning to ask since June. Every one of those is unscheduled work with no date attached, which is the whole reason a question pile behaves the way it does, and client questions is where that lives.
Some of it is an early delivery. One form, sometimes one photograph of one form, arriving months before the rest of that client’s file and unmatched to anything, because you have not built the list it belongs against yet.
And some of it is silence, which is the largest of the three and the one that has to end up somewhere with a date on it, or it becomes a client you assume is coming who is not.
The arithmetic is worth doing before the send rather than after. Four hundred and sixty messages at a fifteen per cent reply rate in the first ten days is roughly seventy replies, most needing a human decision, landing in the same week, on top of the fourth-estimate run and the December closes. That is a March-shaped week, in January, and it happened because everything went out on a Tuesday.
Corinne’s decision this year was to stagger it. Businesses first, in the second week of December, because their deadlines come in March and their replies are the ones that unblock the most work. Individuals in three alphabetical batches across January. Not out of politeness to the clients, who neither notice nor care. Because the replies arrive in proportion to the sends and her capacity to answer them is flat, and the only variable she controls is the sending.
The signature half of that batch, which is quieter and slower and blocks nothing until it blocks everything, belongs to engagement letters. The requests half, and why a document is late for about six reasons of which forgetting is only one, is chasing client documents. What is decided in December is not how to do either. It is when they land.
The change that cannot be made in March
If the firm is going to change how the mailbox works, this is the window, and there is a reason that is not just about having time.
Anything that ranks your mail has to learn your practice, and it learns it from your mail, over weeks. Which senders you answer inside the hour. Which threads you leave for Thursday and are right to. What you actually mean when you write back in three lines. That learning has to happen somewhere, and December is two weeks where being wrong about it costs nothing, because the messages it gets wrong are messages with no date on them. February is two weeks of running a season on something you have not learned to read yet, while also running the season.
Corinne connected Point in the first week of December. Not the last week, because the last week is holidays and half the firm is out, and a fortnight of learning needs a fortnight of ordinary traffic to learn from. It runs on top of the mailbox the firm already keeps, so there was no migration and no new address to tell four hundred clients about in the worst possible month to tell them anything, and the fortnight that follows is walked day by day in connecting the inbox you already have.
What she wanted in place by the second week of January was narrow. Mail ranked before she sits down, so the first screen of a season morning is a judgment rather than a delivery order. A plain summary on a thread before she opens it, which matters most on the forwarded chains from bookkeepers that carry no words of their own. An ask inside a message turning into a task with a date on it, so that a promise made on the fourth of March is not held in the same head that is holding forty others. The full inventory of what it does is on benefits, and the version of it written for practices is AI email for accountants.
What she set deliberately low was how far any of it goes on its own. The dial is per kind of work rather than one setting for everything, and review is where it sits out of the box, which is the correct place to run a first season from. Filing and ranking can be left to get on with it. Anything that writes to a client is worth watching through a first March before you decide differently.
Two honest notes belong here, because December is when they are cheap to act on.
The first is that a light month teaches a light-month version of your practice. What Point knows on the second of January is Corinne’s December, and Corinne’s December is not Corinne’s March. The corrections that matter most are the ones made in the first fortnight of the season, when the mail changes shape and the ranking has not caught up yet. Connecting early does not remove that. It means the correcting happens on a system you already know how to correct.
The second is a boundary worth naming plainly. If what the firm actually needs is a status list per client showing which of eleven documents have arrived and been accepted, an email client is not that, and no amount of ranking makes it that. Email carries requests well and holds registers badly, which is the whole argument of one PBC list rather than five copies of it. A practice can want both things and should know which one it is buying. What Point changes is what reaches you and in what order, and that is a real problem in a season, and it is not the same problem as knowing where every file stands.
What the second week of January does not care about
Corinne got through most of it. The sent-items hour, done on a Thursday afternoon. The list of names, rebuilt from the engagement list, ninety-one entries where last year’s had sixty-two, and thirty of the new ones people who have never once emailed her. The organizer batch staggered. Point connected on the fourth, wrong about her for eight days, sensible about her by the fifteenth.
One thing she did not settle, and she knew it at the time. Four people in the firm now write to clients, and a client answers the person whose name was on the last message, which is sensible behaviour nobody is going to talk them out of. Where the record of a request lives when the request went out from somebody else is a question she left in December, told herself she would take in the first quiet week of the season, and there is no quiet week in the season.
That is the shape of it. December does not finish; it runs out. Whatever was decided is what the firm has, and whatever was not decided is a thing the firm will meet again in March at four times the price.
None of which the calendar consults anybody about. The first forms of the season arrive well before any deadline requires them, from the clients who are early rather than the ones you are thinking about, in ones and twos, often forwarded with nothing written above them.
And the first one that lands on Corinne’s screen will not say, on the morning it arrives, which of the two jobs it belongs to. There is the pile the practice has to collect, and there is the pile the practice has to issue, and they arrive in the same fortnight under the same word, from senders that look alike, into one mailbox. Sorting one from the other is the first real work of January, and getting it wrong is expensive in a way that does not show up until the end of the month.
