An engagement letter is the one thing in a practice mailbox you send out and then wait to get back. What you’re waiting for is a single act. One person performs it, and they have no other reason to think about you that day. Until they do, everything in the firm carries on as normal. That’s the whole of the difficulty.
- Every other item you’re owed announces itself by halting a desk. This one lets the work carry on. It becomes a problem on the day you’re ready to deliver.
- It’s the single outstanding item where the client sincerely believes they’ve already answered you. They replied. To them that was the reply.
- It goes to the entire client list on one morning. 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. 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’s sitting on a desk waiting for it. Each is in the mail because somebody outside the firm holds it and you don’t.
The engagement letter travels the other way. You wrote it. You already hold every word of it. What has to come back is assent, recorded in a form you can keep.
That inversion changes how the thing behaves in a mailbox. 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’s still to begin. There’s nothing for the client to be anxious about, and no natural point in their week where it becomes the next thing. So it can sit unopened for two weeks, and the client feels they’ve been perfectly attentive.
Then there’s 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’s the first formal thing you send, and it gets signed quickly because it’s obviously the door into the relationship. For a client of eleven years it’s the same PDF as last year with a new date. Their honest reading is that it’s a formality between people who 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 the reason a practice can go most of a season before discovering that a letter never came back.
Why an unsigned letter is silent
A missing bank statement reports itself. The preparer opens the file, stalls, and the job sits in a stage where anybody looking can see it has stopped. That self-reporting property does more work in a practice than it gets credit for. 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 blocks nothing, so it stays quiet.
The organizer comes back. The statements arrive. The preparer has everything a return needs and builds it, because the work never asks whether the letter came back. A firm can prepare a whole return under an engagement it never had signed, and the tax software, the ledger and the mailbox all stay quiet about it. Every party in the chain has a perfectly good reason to look elsewhere.
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. The missing signature stops being an administrative loose end and becomes the reason a client can’t be filed on time. The other is the day something goes wrong, when the document you can’t produce is precisely the one that would have said what you agreed to do.
That puts the letter in a class of its own on the list of what you’re 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. The day gives you no moment where an unsigned letter comes up, so judgment has nowhere to act. It has to be a stage a job can’t pass, decided in advance by people who are calm. 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. Leave it to a preparer and it goes unmade, because a preparer gets 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’s 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’s the reply that arrives most often. It’s the reason so many letters are recorded as handled while the signature is still outstanding.
That all looks fine. Yes, go ahead. Same as last year, please.
Read those in an inbox and they close the thread. They’re answers. They’re courteous, prompt, unambiguous answers, and from the client’s side the matter is now dealt with. Write to them again in two weeks and the honest reading available to them is that you skipped what they sent.
This is what makes chasing a signature genuinely unlike chasing a document. When a statement is still to be sent, both sides know it, and a reminder tells the client something true that they had forgotten. When a letter is still to be signed, one side thinks it’s done. A reminder tells them something they believe to be false.
So the message that works explains. In one sentence, and with no suggestion that the client did anything wrong, it says the reply was the agreement and the file needs the signature. Then it makes the signature the only thing left to do. Putting the requirement outside the relationship helps, because it sits 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. 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 often somewhere else in the building. The controller or the office manager handles everything else you send, answers promptly, and will sign this too if nobody says otherwise. Theirs is the signature you’ll get first, precisely because they’re the responsive one. 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’s the half that matters on the day anybody asks.
So the tick against a client’s name means 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’s the condition on the work happening at all, so its last useful day comes from the day you intend to open the file. Once a preparer has started, the letter is already late however much room is left before the deadline, and the deadline moving buys it nothing.
So the chase date for a letter comes out of your own schedule for that client rather than out of the calendar everybody shares. Say you plan to work a client 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 that file feels relaxed to everybody. That date always feels early. It is early. It’s also correct, and it’s 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’s worth more than it looks. Send the letter on its own, away from the organizer.
Sending them together is the efficient thing to do, and it’s why a great many letters go unsigned. A signature is the fastest item you’ll ever ask a client for, and an organizer 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 the specific error: the letter is the one thing you send that’s genuinely quick, so let it travel alone.
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 look alike: same subject line, same shape, same attachment. On the surface, the eleven that need a person sit flush with the hundred and ninety that need nothing.
Worse, the question you actually have lives outside the mail. Whose letter is still outstanding is a question about your client list. A mailbox can tell you with complete accuracy what has arrived. Who is missing stays invisible to it, because absence never arrives. The roster lives in your practice management system or your billing system, the returns live in the mail, and somebody sitting down with both open is what joins the two.
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 done. It has to be weekly rather than at the end, because two weeks of silence is recoverable in December and is beyond recovery 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 deliberate. They’re deciding, or they’re working out how to raise it, and that’s the most informative silence in the whole batch. A client who’s leaving a firm very often leaves by letting the letter go unsigned, because it’s the least confrontational exit available to them and it asks them to say nothing at all. An unsigned renewal from a client of nine years is a retention question several weeks before it’s an administrative one, and it’s 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’s a K-1 coming from a partnership nobody had heard of. Or that the business registered in a second state in the fall and they assumed you knew.
The work you’re now doing has moved past what the document describes, and the document has no idea, because it’s filed. Nothing watches a filed thing.
That gap costs a firm in two separate ways, and they’re 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’s 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 ordinary 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. Doing something is the part that matters, and the cheapest version of something is a reply, sent that week, naming the change in plain words. A confirming email ranks below an engagement letter. It’s dated, it sits in both files, and it’s 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. The part firms currently find hardest is what to write about AI and where the client’s permission belongs, and that’s 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 can’t 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 is gone for good: 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 still in transit rather than filed, 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 the client can’t send you again 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. What was above it stays an open question, 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 a mailbox search for the word engagement satisfies none of them.
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 judgment 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. Through a letter run that keeps the client querying their fee near the top, rather than 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, before you open any of them.
Three things fit a letter in particular. Put a standing request in plain words on the client you’re genuinely waiting on, and you hear once, on the morning the signed copy lands, rather than going to look. Attachments 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 you can ask a question of a document. The answer comes back with a pointer to the part of the file it was taken from. On a returned letter that settles the one thing you need before filing it: whether the page carrying the signatures came with it.
The waiting is held the same way as anything else you’re owed. A letter you’ve sent 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 arrive already drafted in 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 on the day an unsigned renewal turns into asking a client of nine years for twenty minutes. How far Point goes alone is set for each kind of action separately, 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 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. One limit holds for any mail software: once a message has reached the person you sent it to, it has been sent.
Point sits on top of the mailbox your practice already has, Google or Microsoft, so the address at the top of the letter is untouched.
The roster stays with you. Point holds no list of which two hundred clients were sent a letter this year. Point reads a signed copy and an unsigned one the same way as a matter of record. Point has no view on whether the person who signed could bind the entity, and Point leaves a preparer free to start 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’s whatever happens in the third week of March. The only real question is whether anybody chose it deliberately. An unsigned letter stops nothing, so a preparer is never prompted to ask, which rules out deciding case by case. Whatever the rule is, it has to be a stage a job can’t 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 can’t see. What’s certain is that your file is meant to hold a signed letter, and a signed letter is what you’d 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?
Work forwards from the day you intend to open that client’s file, and set the chase for a week or so before it. The letter is the condition on the work starting, so your own schedule sets the date rather than the filing deadline. That date lands earlier than politeness suggests and earlier than it does for any document, which is correct, because a document that’s still to arrive will announce itself and a letter that’s still to be signed stays quiet. 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. 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. Two causes survive it, and they’re the pair that lose most letters: the client who believes their reply was the answer and leaves the request unopened, 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. The work carries on while the letter is missing, so it has to be a stage a job can’t pass rather than something anybody remembers. The client who replied believes they’ve 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 rather than backwards from April, which makes the right chase date feel early. The annual run is a roster reconciliation rather than 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.
