How to Write Case Studies for Accounting Firms That Actually Get Read

04 September 2026·3 min read

Quick answer: A case study that actually gets read follows four parts: a specific, relatable problem, what you actually did (the process, not just the headline), the result described honestly (rounded or ranged if exact figures can't be disclosed), and what it means for a reader in a similar position. Composite, anonymised stories work just as well as named ones, and are often safer. 📝

Most accounting firm case studies read like a sales brochure with a client's name stapled on — "we helped ABC Pty Ltd save money and grow!" — and nobody remembers a word of it. 💖 A case study that actually works reads like a story a business owner recognises themselves in, with just enough specific detail to feel real and just enough restraint to stay professionally appropriate.

What most firms get wrong

Two failure modes again: vague to the point of meaningless ("we helped a client with their tax"), or so specific it effectively identifies a real business, which raises confidentiality problems even with a name changed — unusual numbers, industries, or timelines can still be recognisable, especially in a small town or tight-knit industry.

The 4-part case study template:

The problem. Specific and relatable — "a trades business owner was three BAS periods behind and dreading every ATO letter."
What we did. The actual process, not just the outcome — clients trust firms whose process they can picture.
The result. Rounded or ranged figures ("reduced admin time by roughly a third") unless you have explicit written consent to use exact numbers.
What this means for you. Bring it back to the reader — "if this sounds familiar, here's what a first conversation with us looks like."

Client permission checklist: written consent, a chance to review the draft, and the option to stay fully anonymous or composite if they'd rather.

A business advisory firm: Wrote a composite case study about "a trades business owner drowning in reconciliation" rather than naming a real client — it converted just as well in sales conversations as their earlier named case studies, without any permission friction.

A virtual CFO firm: Published a case study about restructuring ahead of a funding round, with all dollar figures rounded to a range rather than exact numbers — enough to be credible, not enough to be traceable through public ASIC filings.

A bookkeeping firm: Ran a before-and-after workflow case study for an e-commerce client — screenshots of a messier process versus a cleaner one did more persuasive work than any written testimonial could.

How to actually get one written

Interview the client rather than asking them to write it themselves — most people are bad at describing their own transformation and undersell it. Ask what it felt like before, what almost stopped them from getting help, and what surprised them about working with you. Always send the draft back for their approval before publishing, and offer composite/anonymous as a genuine, easy option, not an afterthought.

💡 Composite case studies are often the safer, better choice. You lose nothing in persuasive power and remove the permission and confidentiality risk entirely.

Mistakes to avoid

Publishing without written consent, even for a "small" mention.
Using exact dollar figures that could be cross-referenced against public filings.
Writing it as a brochure instead of a story with a beginning, middle, and end.
Implying a guaranteed or typical result rather than describing one specific situation honestly.

Please note: general marketing information, not compliance advice. Avoid implying guaranteed or typical outcomes, and check current TPB guidance on advertising before publishing client results.

Frequently asked questions

Can we use exact dollar figures with client permission?

Only with clear written consent — and even then, consider whether rounding protects the client from being identified via public record, such as ASIC company filings.

Do composite case studies need a disclaimer?

Yes — a simple line noting the story is a composite or illustrative example, not a specific client, keeps it honest and avoids any impression of a fabricated testimonial.

How long should a case study be?

300-500 words is usually enough. Longer than that and most readers skim past the detail that actually persuades them.

Should case studies live on the website or just in sales conversations?

Both — a case study page helps SEO and pre-sells skeptical visitors, but the same story is often even more effective sent directly during a live sales conversation when the objection it answers comes up.
