Engagement Letters on Your Firm’s Letterhead in Word
By the WordLetterhead Team · Last updated:

Every engagement letter that goes out this season is typed in Word — and it should go out on the firm’s letterhead, not on a file someone half-fixed last February. The quiet weeks before busy season are when to set the letterhead file right, once.
What file should engagement letters be typed on?
A Word document with the firm’s letterhead locked in the header layer: the design repeats on every page, prints at full strength by default, and can’t be clicked, dragged, or deleted while anyone types or pastes over last year’s language. Everything else — pasted logos, converted PDFs — degrades a little with every letter that touches it.
Why the header layer wins over every alternative is the short version of every method compared; what the lock actually protects against is in locking a letterhead in Word.
Why fix this before busy season?
Volume multiplies whatever file you start with. Engagement letters go out in batches, and most are last year’s letter re-edited — so a letterhead that drifts or a logo that’s a few pixels off doesn’t go wrong once, it goes wrong on every client’s first impression of the year. A locked file makes the re-edit routine safe: staff change dates, names, and fees; the letterhead can’t move.
How does the setup work?
Two minutes, from the letterhead the firm already has — the designer’s PDF, or a clean PNG or JPG. WordLetterhead builds the .docx around it:
- Upload the firm’s letterhead file.
- Drag the typing area where the letter text belongs.
- Download the .docx — that’s the season’s master letter file.
No account, and nothing to install on anyone’s machine. The letters themselves never touch our servers — they’re typed in your copy of Word. Just opening the practice? Start with setting the letterhead up first.
Common questions
- Can we reuse the file next season?
- Yes — it’s a normal .docx you own outright. Keep a clean master copy, reuse it every season, and only rebuild (two minutes, $9) when the firm’s branding actually changes.
- Our engagement letters run several pages. Does the letterhead hold up?
- Yes — the artwork is anchored in the header, so page 6 renders exactly like page 1 with no per-page setup. The file also ships with the first-page split pre-configured, for firms that prefer full letterhead on page 1 and cleaner continuation pages.
- Does WordLetterhead see our client letters?
- No. Letters are typed in your copy of Word, in your file. The free sample renders locally in your browser without uploading anything; buying the clean file uploads only the rendered letterhead artwork, which is assembled into the .docx in memory and never stored.
- Multiple partners or offices with different letterheads?
- Each letterhead design becomes its own $9 file — upload each variant once. There’s no subscription and no per-user pricing, so a firm with two office letterheads pays for two builds and nothing after that.
