The Engagement Letter That Never Got Signed
An unsigned engagement letter is a risk you carry, not a formality you can skip. Here's how to make signing the default before work begins.
Most firms have engagement letters. Fewer firms have signed engagement letters for every active client. That gap — between the letter that was sent and the letter that came back signed — is where scope creep, fee disputes and professional-standards headaches quietly live.
It rarely feels urgent. The client is friendly, the work is already underway, and chasing a signature feels awkward when you're mid-job. So the letter sits half-complete in a folder somewhere, and everyone gets on with the actual accounting. Then something goes wrong — a fee query, a scope argument, a complaint — and the first question is: what did we actually agree to, and can you prove it?
Why the unsigned letter is worse than no letter
An engagement letter does two jobs. It sets out the scope of work and fee, and it records that both parties agreed to it. A letter you sent but never got back does the first job and fails the second. Worse, it can create a false sense of security — you feel covered because you "have engagement letters" as a policy, when the specific client in front of you never signed.
The practical risks are familiar to anyone who has run a practice for a few years:
- Scope disputes. The client thought BAS reviews were included. You thought they were extra. Without a signed document, it's your word against theirs.
- Fee recovery. If you ever need to enforce payment, an unsigned engagement gives you far weaker ground.
- Professional standards. APES 305 expects the terms of engagement to be documented. A drawer full of drafts isn't documentation of agreement.
- Staff confusion. Your team can't deliver against a scope nobody confirmed. They end up guessing what's in and what's out.
The letter that never got signed isn't a paperwork problem. It's an unmanaged liability sitting inside your client accounting relationships.
Why it happens (and it's not laziness)
The signature gap almost always comes down to friction and timing, not intent.
Friction: If signing means printing, scanning, or opening a separate DocuSign account, a proportion of clients will simply not get around to it. Every extra step loses people.
Timing: If the letter goes out after work has already started, the incentive to sign disappears. The client is already being served, so the document feels like admin rather than a gate. Nobody chases a signature for work that's already half done.
Visibility: Once a letter is sent, most firms have no easy way to see which ones came back. There's no list of "sent but unsigned" clients. So the gap is invisible until it bites.
Make signing the default, not the follow-up
The fix is structural, not a matter of trying harder to remember. You want signing to be built into the moment work begins, with as little friction as the technology allows.
1. Send the letter before the work, every time
Tie the engagement letter to onboarding and to any new service. New client? Letter first. Adding SMSF work to an existing client? New engagement scope, signed, before you touch it. The letter should be the thing that starts the work, not the thing that trails behind it.
2. Use e-signing so there's nothing to print
The single biggest lever on return rates is removing every physical step. When a client can review and sign on their phone in under a minute, the excuses evaporate. E-signing built into your account practice management software means the letter, the sign request and the completed record all live in one place — no separate tool, no attachments floating around in email.
3. Build letters from your service catalogue
The scope in the letter should match the services you actually deliver and price. If you sell compliance as defined packages, your engagement letters can be assembled from those same building blocks — annual accounts, tax return preparation, BAS, advisory — with the fee attached. This keeps the letter accurate and makes it fast to produce. It also means the scope in the signed document lines up exactly with the work items your team delivers against.
4. Track signed vs unsigned as a live status
You should be able to answer, at any moment, "which active clients don't have a current signed engagement?" That's a report, not an archaeology dig. Good accounting client management software treats signature status as a tracked state — sent, viewed, signed — so a stalled letter is visible immediately, and a reminder can go automatically instead of relying on someone to notice.
How this looks in practice
In Finye, engagement letters are part of the same system that holds your client records, service catalogue and work boards. You build a letter from the services and pricing you've already defined, send it for e-signing, and the client signs from a link — no printing, no third-party account. The signed document is stored against the client, and the signature status is visible so you can see at a glance who's outstanding.
Because it sits alongside onboarding and the client portal, you can make the signed letter the gate that opens the work: portal access, document requests and the first job all key off an engagement that's actually agreed. The letter stops being a follow-up task and becomes the natural first step of the relationship.
This isn't about heavier admin. It's the opposite — when signing is frictionless and tracked, you stop spending time chasing and stop carrying invisible risk. The client experience improves too, because they know exactly what they're paying for and what's included before any invoice arrives.
The quiet audit worth running this week
Pull your active client list. For each one, answer a single question: is there a current, signed engagement letter that matches the work we're actually doing? Most firms find the answer is "no" more often than they'd like — old clients whose scope has quietly expanded, clients onboarded in a rush, letters sent but never returned.
Every gap on that list is a fee you can't cleanly defend and a scope you can't cleanly enforce. Closing it isn't dramatic work. It's sending a letter, getting a signature, and — going forward — making sure the signature is the thing that lets the work begin, not an afterthought you'll get to eventually.
