Quick answer

Once your services catalogue and a letter template are set up in Remindoo, you can create a letter of engagement in under 30 seconds by pulling the client's services and details into the template and sending it for e-signature. The slow part isn't the letter — it's the one-off setup most firms never do.

What does it actually take to create a letter of engagement in 30 seconds?

It takes a pre-built template, a services catalogue with your current pricing, and software that merges client details into both automatically — the letter itself is then a selection, not a rewrite.

Most firms treat every letter of engagement as a new document. Someone opens last year's Word file, changes the client name, checks the fee, hopes the scope wording hasn't changed, and emails it as a PDF. That's ten to twenty minutes of careful editing, done under time pressure, usually the same week new clients are already asking when their first job will start.

The 30-second version isn't magic — it's preparation. If your services and prices live in one catalogue, and your engagement letter wording lives in one template, creating a letter becomes: pick the client, pick the services, send. The editing work happens once, when you build the template, not every single time you take on a client.

Why slow engagement letters cost UK practices clients

A partner I know used to send letters of engagement the same way most of us learned to — copy the last one, change the name, check nothing embarrassing was left in from the previous client. It worked fine when he onboarded four or five clients a year. Then a referral drive brought in fifteen new enquiries in a month, and the same process fell apart.

Two letters went out with the wrong fee. One went out with another client's name still in the footer. A prospect who'd verbally agreed to sign chased three times over a week before the letter arrived — by then he'd started using a competitor who'd sent theirs the same day.

None of this was about the fee or the service. It was entirely about how long it took to turn a 'yes' into a signed piece of paper.

  1. Client says yes
  2. Someone finds last year's template
  3. Fee and scope get manually checked
  4. Letter sits in a draft folder
  5. Leak: Client chases or walks

Signs you have this problem

  • You keep a folder of old engagement letters to copy from rather than a single template
  • Fees or scope wording have gone out wrong more than once
  • New clients wait several days for paperwork after agreeing verbally
  • Different partners word the same service differently in letters
  • You can't say how many letters are still unsigned right now

How to create a letter of engagement in under 30 seconds: step by step

  1. 1

    Build a services and pricing catalogue

    List every service you offer with current pricing, so a letter never needs a fee typed from memory.

  2. 2

    Write one engagement letter template per common service bundle

    Sole trader, limited company, payroll add-on — a handful of templates covers most new clients.

  3. 3

    Set your standard scope and exclusions wording once

    Agree the wording with a partner or your professional body, then lock it into the template so it doesn't drift between staff.

  4. 4

    Pull client details in automatically

    Use a system that merges the client's name, entity type and agreed services into the template rather than retyping them.

  5. 5

    Send for e-signature immediately

    Send the letter by email with an e-signature link the same day the client says yes.

  6. 6

    Track what's unsigned

    Use proposal filters to see every unsigned letter at a glance and set a reminder to follow up.

  7. 7

    Convert on signature

    When the letter is signed, move the client straight into onboarding rather than leaving them in limbo.

Send this alongside the letter itself, once the template and catalogue are set up.

How does Remindoo make engagement letters this fast?

Remindoo's drag-and-drop templates and services catalogue are the two pieces most firms never build. Once your services and prices are set up in the catalogue and your standard wording is in a template, creating a letter of engagement is a matter of selecting the client and the services agreed — not writing a document. The letter sends by email with an e-signature link built in, so the client can sign online rather than printing and scanning anything back. Proposal filters show you every letter that's drafted, sent or still unsigned, so nothing sits forgotten in someone's inbox. When a lead signs, Remindoo converts them into an active client record without you re-typing their details, so onboarding starts the same day. It's free for 60 days, so you can build your first templates and see the time this saves before deciding whether to continue.

Frequently asked questions

Is 30 seconds realistic for every letter?

It's realistic once your services catalogue and templates are set up. That setup takes an afternoon, not seconds — after that, most letters are genuinely fast.

Does Remindoo write the legal wording for me?

No. You or your professional body should set the scope, exclusions and terms wording. Remindoo stores it in a template so it's applied consistently.

Can different partners use different fees for the same service?

You can set that up, but the point of a shared catalogue is to stop unintentional inconsistency between partners quoting the same job.

What happens if a client wants to negotiate the fee?

You can edit the letter before sending — the template is a starting point, not a locked document.

Is this free to try?

Yes, Remindoo is free for 60 days, including the proposal templates, catalogue and e-signature features.

Does a fast letter reduce how professional it looks?

No — the client sees a clean, consistent letter either way. Speed comes from your setup, not from cutting corners on content.

Why tracking leads and proposals matters

Every enquiry a practice fails to follow up is lost fee income. A clear pipeline shows which prospects need a reply, a proposal or a follow-up.

Faster replies

Prospects often contact more than one firm, so the firm that replies first and clearly has an advantage.

Consistent proposals

Templates and a services catalogue keep scope and pricing consistent whoever writes the proposal.

Signed terms from day one

E-signed engagement letters confirm scope and responsibilities before work begins.

No re-keying

Converting a won lead into a client keeps the details you already collected.

Practical tips from UK practice

  • Reply to every new enquiry within one working day.
  • Use lead statuses that match your real sales stages, and review them weekly.
  • Send the engagement letter with the proposal so the client signs once.
  • Record why lost leads were lost, to improve pricing and messaging.
