An engagement letter is the only thing in a practice mailbox that you send out and then wait to get back, and what you are waiting for is not information. It is a single act, performed by somebody who has no other reason to think about you that day. Until it happens nothing in the firm stops, which is the whole of the difficulty.
- Every other item you are owed announces itself by halting a desk. This one lets the work carry on and only becomes a problem on the day you are ready to deliver.
- It is the single outstanding item where the client sincerely believes they have already answered you. They replied. To them that was the reply.
- It goes to the entire client list on one morning, so knowing where it stands is a reconciliation against a roster rather than a reading of the mail.
- The letter is signed in January and stops describing the work in March, and the thing that changed it arrived as a sentence in the middle of a thread about something else.
The one document that goes out from you
Nearly everything in an accounting mailbox is inbound and unfinished. A bank statement, a K-1, a payroll summary, an answer to a question somebody asked three weeks ago: each is a piece of a job that is sitting on a desk waiting for it, and each is in the mail because somebody outside the firm has it and you do not.
The engagement letter travels the other way. You wrote it. You already hold every word of it. What has to come back is not a document in any useful sense, it is assent, recorded in a form you can keep.
That inversion is not a curiosity. It changes how the thing behaves in a mailbox, and every difficulty a firm has with engagement letters comes out of one of those changes.
Start with the smallest. The letter lands in a client’s inbox at the one moment in the year when nothing is happening to them. Every other message you send is attached to live work: a question about their van, a note that their statements arrived, a warning that a date is close. The letter is attached to work that has not begun. There is nothing for the client to be anxious about and no natural point in their week where it becomes the next thing, which is why it can sit unopened for a fortnight without anybody feeling they are ignoring you.
Then there is the difference between a first letter and a fifteenth. For a new client the letter is part of being taken on: it arrives in the middle of a conversation, it is the first formal thing you send, and it gets signed quickly because it is obviously the door into the relationship. For a client of eleven years it is the same PDF as last year with a new date, and their honest reading of it is that it is a formality between people who have long since agreed. Firms put real thought into the letter that goes to a new client and almost none into the one that goes to everybody else. The signature that goes missing is nearly always a renewal.
Both of those are mild. The third change is not, and it is the reason a practice can go most of a season without discovering that a letter never came back.
Why an unsigned letter is silent
A missing bank statement reports itself. The preparer opens the file, cannot finish, and the job sits in a stage where anybody looking can see it has stopped. That self-reporting property is doing more work in a practice than it gets credit for, and most of what any firm knows about its own outstanding items comes from it rather than from a system. Managing client document requests is about the mail around items that behave that way.
The engagement letter has no such property, because it blocks nothing.
The organiser comes back. The statements arrive. The preparer has everything a return needs and builds it, because there is no point in the process where the work asks whether the letter came back. Nothing in the tax software, the ledger or the mailbox is capable of noticing that a firm is preparing a return under an engagement it has never had signed. Every party in the chain has a perfectly good reason not to look.
So it surfaces late, and the two moments it surfaces are the worst two available. One is the day the return is finished and ready to go out, with a date against it, when the missing signature stops being an administrative loose end and becomes the reason a client cannot be filed on time. The other is the day something goes wrong, when the document you cannot produce is precisely the one that would have said what you agreed to do.
Which puts the letter in a class of its own on the list of what you are owed. For everything else, if the firm forgets, the work reminds it. For this one, if the firm forgets, the work covers for it.
The consequence is unwelcome but short. Because nothing in the day surfaces an unsigned letter, it cannot be handled by judgement at the moment it matters, since there is no such moment. It has to be a stage that a job cannot pass, decided in advance by people who are not under pressure. Whether that stage is an absolute stop, or a stop with a partner’s named exception, is a decision for your firm and whoever insures it. What does not work is leaving it to a preparer, who receives no signal at any point that anything is missing at all.
Every practice already has a policy on this, in the only sense that counts. It is whatever the firm actually does in the third week of March. The useful question is whether anybody wrote it down while they could still think clearly about it.
What you are waiting for is not a reply
Here is the reply that arrives most often, and it is the reason so many letters are recorded as handled when they are not.
That all looks fine. Yes, go ahead. Same as last year, please.
Read those in an inbox and they close the thread. They are answers. They are courteous, prompt, unambiguous answers, and from the client’s side the matter is now dealt with. Write to them again in a fortnight and the honest reading available to them is that you did not read what they sent.
This is what makes chasing a signature genuinely unlike chasing a document. When a statement has not been sent, both sides know it has not been sent, and a reminder tells the client something true that they had forgotten. When a letter has not been signed, one side thinks it is done. A reminder tells them something they believe to be false.
So the message that works does not remind. It explains, in one sentence and without any suggestion that the client did something wrong, that the reply was the agreement and the file needs the signature, and then it makes the signature the only thing left to do. Putting the requirement outside the relationship helps, because it is outside the relationship: this is what the firm has to hold, rather than what the firm wants from you. Nobody argues with a filing cabinet.
Underneath that sits the harder half, which is who has actually signed.
A joint return has two signers, and the second one is usually the person who never saw the email. What comes back is a letter carrying one signature, and a letter carrying one of two signatures is filed as complete far more often than anybody in the firm would admit, because at a glance it looks like every other returned letter.
An entity’s letter needs somebody with the authority to bind the entity, and that person is frequently not the one reading your mail. The controller or the office manager handles everything else you send, answers promptly, and will sign this too if nobody says otherwise. Their signature is the one you will get first, precisely because they are the responsive one, and the entire value of the document is that it binds somebody who can be bound.
And the date. A letter that comes back undated, or countersigned at your end three weeks after it arrived, has lost the one fact it exists to record. What was agreed is only half of it. From when is the other half, and it is the half that matters on the day anybody asks.
So the tick against a client’s name is not that they replied. It is a signed copy, carrying every signature it needs, from somebody who could give it, with a date on it.
The clock that runs forwards
Every other request a practice sends has a last useful day worked backwards from a date somebody else set. Take the deadline, subtract what still has to happen at your end once the thing arrives, and the remainder is the client’s window. That arithmetic, and the way the queue on the desks shortens the answer as a season runs, is set out in running the firm inbox and inbox zero during busy season.
The letter inverts it, and this is the practical reason its dates get set wrong.
A signed letter is not an input to the return. It is the condition on the work happening at all, so its last useful day is not derived from the filing date. It is the day you intend to open the file. Once a preparer has started, the letter is already late no matter how much room is left before the deadline, and the deadline moving does not buy it a single day.
Which means the chase date for a letter comes out of your own schedule for that client rather than out of the calendar everybody shares. For a client you plan to work in the second week of February, a letter sent in December and unsigned by the middle of January is overdue in January, at a point when nothing about that file feels urgent to anybody. That date always feels early. It is early. It is also correct, and it is the only kind of date that can be right about a thing that gives no other warning.
One small decision follows from this and it is worth more than it looks. Do not send the letter stapled to the organiser.
Sending them together is the efficient thing to do and it is why a great many letters go unsigned. A signature is the fastest item you will ever ask a client for, and an organiser is the slowest: one is done on a sofa in ninety seconds, the other needs an evening and a filing drawer. Bundled into one message they travel at the speed of the slower one, and the client who has decided to deal with all of it on Sunday deals with none of it. Managing client document requests makes the general case about what a client can act on the morning it lands. What belongs here is only the specific error: the letter is the one thing you send that is genuinely quick, so do not attach it to something that is not.
The batch nobody reconciles
Engagement letters are the only mail in a practice that goes to everybody at once.
Everything else is staggered by the shape of the work. Requests go out when a job starts, questions go out when a preparer hits one, chases go out when a date passes. The annual letter run is one morning’s work followed by ten days in which the mailbox fills with replies that are indistinguishable from each other: same subject line, same shape, same attachment, and nothing on the surface to separate the eleven that need a person from the hundred and ninety that do not.
Worse, the question you actually have cannot be answered by reading any of them. Whose letter has not come back is a question about your client list, not about your mail. A mailbox can tell you with complete accuracy what has arrived. It has no way of telling you who is missing, because absence never arrives. The roster lives in your practice management system or your billing system, and the returns live in the mail, and nothing joins the two except somebody sitting down with both open.
So the count is simple and it has to be somebody’s job. Sent, less returned, run against the roster, weekly through the send window and then not again. The reason it must be weekly rather than at the end is that a fortnight of silence is recoverable in December and is not recoverable in March.
Two things make that count much smaller.
Stagger the send. A run that goes out over three weeks in groups produces a return stream a person can work through and reconcile as it lands. A run that goes out on one Tuesday produces a wall, then silence, then a number nobody has looked at since.
And sort the quiet ones by what changed. If a client’s letter carried a fee increase, a narrowed scope or a new condition, their silence is not inattention. They are deciding, or they are working out how to raise it, and that is the most informative silence in the whole batch. A client who is leaving a firm very often leaves by not signing, because it is the least confrontational exit available to them and it requires them to say nothing at all. An unsigned renewal from a client of nine years is a retention question several weeks before it is an administrative one, and it is answered by a phone call rather than by a third copy of the letter.
The letter stops being true in March
The letter that got signed describes a return with two states and a Schedule C. Then in March the client mentions, in the middle of a message about something else, that they sold the rental in July. Or that there is a K-1 coming from a partnership nobody had heard of. Or that the business registered in a second state in the autumn and they assumed you knew.
The work you are now doing is not the work the document describes, and the document has no idea, because it is filed. Nothing watches a filed thing.
That gap costs a firm in two separate ways and they are worth keeping apart. One is money: the fee conversation happens after the work rather than before it, which is a worse conversation for everybody and a much harder one to win. One PBC list makes the case about when a job that has grown should be raised, and the timing argument there applies here unchanged. The other is professional: work outside the letter is work agreed informally, which is the exact condition the document exists to prevent.
The part of this the mailbox owns is small and precise. When a client’s message changes what the job is, that is an event rather than a line in a thread, and somebody has to catch it in the week it arrives.
The phrases worth reading twice are not dramatic ones. Sold, bought, moved, opened, closed, inherited, started. I forgot to mention. One more thing. And the most expensive of all, which is a client telling you cheerfully that they assume something is included.
What you do about it once caught is a question of firm policy and of what your insurer expects, and the honest answer varies with how far the job moved. A new letter, an amendment, or a written note confirming the change may each be right. What is never right is nothing, and the cheapest version of something is a reply, sent that week, naming the change in plain words. A confirming email is not an engagement letter. It is dated, it sits in both files, and it is a very great deal better than a recollection in September.
What the letter should say in the first place is a drafting question rather than an inbox one, and the part of it firms currently find hardest, which is what to write about AI and where the client’s permission belongs, is answered properly in what to put in your engagement letter about AI.
Where the signed one lives
Of everything a client sends a practice in a year, the executed letter is the only item that cannot be obtained again.
A bank statement can be requested a second time. A K-1 can be chased. A signature on a document for a period that has closed cannot be re-created: you can obtain a new letter, signed today, which is a different document and says so on its face. That single asymmetry is why the filing bar for this one item sits higher than for anything else in the mailbox, and three specifics carry it.
It leaves the mail. An attachment, inside a thread, inside one person’s mailbox, is not a filed document, and the case for naming one address as the record for a client’s paperwork is made in running the firm inbox. Everything in it applies here with more force, because this is the one attachment that cannot be re-sourced from the client if it goes astray.
What gets filed is the whole executed document rather than the page that carries the signature. A scan of the last sheet proves a signature exists. It proves nothing about what was above it, and where a fee was renegotiated by telephone and a revised letter went out afterwards, which version came back is the only question anybody will ask.
And the date it returned is kept beside it, because what you agreed and from when are two facts and the second one is the one people go looking for.
The reason to be strict about all three is that this is the document you produce when somebody asks what you undertook to do. That request comes from your insurer, from a successor accountant, from a client who remembers the arrangement differently, or from you in eleven months trying to establish whether the second state was ever in scope. All four want the same short answer, and none of them can be satisfied by searching a mailbox for the word engagement.
Where does Point fit?
Practices ran this on a spreadsheet and a wall chart for a long time before software offered to help, and a careful firm still can. What a tool moves is the noticing and the remembering. The roster, the rule about when work may start, and the judgement about what a change of scope needs stay where they were.
Point weighs each message on two separate questions, how much it matters and how quickly, so during a letter run the client writing to query their fee is not sitting three screens below the hundred and forty confirmations that need nothing. How that weighing is done is a subject in itself. Every thread carries a summary in a line, which through a batch is most of what you want: whether this is a signature, a question or the beginning of a negotiation, without opening any of them.
Three things fit a letter in particular. A standing request in plain words covers the client you are genuinely waiting on, so you hear once, on the morning the signed copy lands, instead of looking. Attachments stop living inside threads and gather into one list, each still joined to the message that carried it, which is where a returned letter is easiest to find and easiest to move somewhere permanent. And a question put to a document is answered with a pointer to the part of the file the answer was taken from, which on a returned letter settles the only thing you need to know before filing it: whether the page carrying the signatures came with it.
The waiting is held the same way as anything else you are owed. A letter you have sent does not disappear into the sent folder. It stays on your list with the date you picked against it, and comes back into view on that day whether or not the client has been on your mind. Where the signed copy has already arrived, the reminder marks itself as probably settled and waits for your agreement, so nobody chases a client the morning after they signed. And a request buried three paragraphs down a client’s message becomes a dated item without anybody retyping it, which is the shape the March scope change usually arrives in.
Replies come back drafted the way you write, so the note explaining that the agreement is settled and the file still needs a signature starts as something to correct rather than something to compose. Point handles the scheduling back-and-forth itself on the day an unsigned renewal turns into asking a client of nine years for twenty minutes. What Point finishes on its own is set separately for each kind of action, and every one of them ships at review, where the work is done and then held. The dial covers that setting properly. Acknowledging a signed letter is the first kind worth raising. The message to a client who has gone quiet over a fee increase is not, and wants somebody’s eyes on it. Everything done is written down in order with the time against it and can be taken back from that line, apart from the one thing no mail software can offer: once a message has reached the person you sent it to, it has been sent.
Point works on top of the mailbox the practice already runs, on Google or on Microsoft, so the address at the top of the letter is untouched.
What Point does not have is the roster. It does not know which two hundred clients were sent a letter this year, it cannot tell a signed copy from an unsigned one as a matter of record, it has no view on whether the person who signed could bind the entity, and it will not stop a preparer starting a return. Those are the parts of this that are the actual work, and they stay yours. The benefits page is the full inventory, Point for accountants walks the same ground through a practice, and whether AI belongs anywhere near a client’s financial affairs is a prior question, answered at length rather than assumed.
Common questions
Should we start work before the engagement letter comes back?
Your firm already has an answer and it is whatever happens in the third week of March, so the only real question is whether anybody chose it deliberately. Because an unsigned letter stops nothing, there is no moment in the work where a preparer is prompted to ask, which rules out deciding case by case: whatever the rule is, it has to be a stage a job cannot pass, set when nobody is under pressure. Whether that stage is an absolute stop or one a partner can name an exception to is a matter for your firm and your insurer, and both of those conversations go better in November than in April.
The client replied “go ahead” but never signed. Is that enough?
Whether an exchange of emails forms a binding agreement is a question for your own adviser and it turns on facts this page cannot see. What is certain is that it is not what your file is meant to hold and not what you would want to produce a year later. The useful way to read that reply is as good news rather than as the answer: the client agrees, so nothing is in dispute and everything left is mechanical. The message that finishes it says exactly that, treats the agreement as settled, and asks only for the signature the file needs.
How long should we wait before chasing an engagement letter?
Do not work backwards from the filing date, because the letter is not an input to the return. Work forwards from the day you intend to open that client’s file, and set the chase for a week or so before it. That date lands earlier than politeness suggests and earlier than it does for any document, which is correct, because a document that has not arrived will announce itself and a letter that has not been signed never will. If a second attempt is needed it should change something rather than repeat the first, and the ladder for that is in managing client document requests.
The scope changed after the letter was signed. Do we need a new one?
That decision belongs to your firm’s policy and to whoever insures the work, and it varies with how far the job actually moved. What the mailbox owes, whichever way it goes, is that somebody noticed in the week the client mentioned it and that a written reply named the change while it was still fresh. Skip that and the only record of what you agreed to do is one clause in a signed letter that stopped being accurate in March, plus a sentence halfway down a thread about something else entirely.
Does an e-signature service fix this?
It fixes two of the causes properly, which is more than most tools manage. The mechanical excuse disappears, since nobody has to find a printer, and the executed copy lands somewhere structured rather than as an attachment in one person’s mail, which is the harder half of the filing problem. What it does not touch is the pair that lose most letters: the client who believes their reply was the answer and never opens the request, and the second signer who was never really in the conversation. It also converts your return stream into machine mail, where the single notification carrying the record looks exactly like the eleven reminders around it. Worth having for what it does. Keep the count on the roster rather than inside whichever system is sending the reminders.
The short version
The engagement letter is the one thing a practice sends out and waits to get back, and what it waits for is an act rather than a document. That inversion is where all the trouble comes from. Nothing in the work stops while it is missing, so it has to be a stage a job cannot pass rather than something anybody remembers. The client who replied believes they have answered, so the chase explains rather than reminds, and the tick means every signature the letter needs, from somebody who can give it, with a date. The clock runs forwards from the day you open the file, not backwards from April, which makes the right chase date feel early. The annual run is a roster reconciliation and not a reading of the mail, and the quiet clients whose letter changed are worth a phone call rather than a third copy. Then watch for the sentence in March that stops the letter being true, and keep the executed copy somewhere it can be produced by whoever is asked. Every other job that comes round on a schedule in a practice has a guide of its own here, and AI email for accountants is where a firm choosing a product should start.
