Webinar Marketing for Accounting Firms: How to Run an EOFY Webinar That Fills the Room

09 August 2026·6 min read

Quick answer: Run an EOFY webinar by picking one tight, specific topic instead of "everything tax," then promote it with a four-email sequence over roughly three weeks — save-the-date, one-week reminder, day-of reminder, and a replay email that's arguably the most valuable one you send. Forty engaged registrants who actually watch and book a call beat four hundred who never open the confirmation email. The real work isn't the 45 minutes live, it's the follow-up in the 14 days after. 📈

Every June, Gold Coast accounting firms have the same idea at the same time: run a webinar. It's a genuinely good idea — webinars let you demonstrate expertise to forty people at once instead of repeating yourself in forty separate meetings. The problem isn't the idea, it's the execution. Most firms spend three weeks building a sixty-slide deck and three days promoting it, when it should be the other way around. We've watched clients build a beautiful, technically correct presentation on Div 7A changes and then wonder why only six people showed up — because the only promotion was one LinkedIn post and a line in the email footer. Getting this right isn't about being flashier online, it's about respecting that your existing clients and prospects are busy, and giving them enough reminders and enough reason to actually block out the time. Done properly, it's one of the few marketing activities that makes your firm feel like the authority in the room, not just another firm sending a newsletter 💖

What most firms get wrong

The biggest mistake is topic width. "EOFY Tax Update" is not a topic, it's a category. Nobody clears their calendar for a category. The firms who fill the room pick something narrow and specific enough that the right person sees the title and thinks "that's literally my situation" — "What the Instant Asset Write-Off Changes Mean If You Run a Trade Business" beats "2026 Tax Time Essentials" every time, because it tells one segment of your list this was built for them specifically.

The second mistake is treating promotion as an afterthought bolted onto a content-first plan. One email a week out and a single social post is not a promotion plan, it's a hope. The firms who get 80-plus registrations for a first-ever webinar are running a proper sequence, not a single announcement.

The four-email webinar promotion sequence (copy this)

Email 1 — Save the date (sent ~3 weeks out)
Subject line formula: "[Topic] is changing — join us [Day, Date]" or "You're invited: [specific outcome] for [client type]"
Example: "Instant asset write-off changes are here — join us Tuesday 17 June"
Body: One paragraph on why this matters right now, who it's for, date/time/duration, one-click register button. Keep it under 120 words.

Email 2 — One-week reminder
Subject line formula: "1 week to go: [Topic]" or "[Number] spots left — [Topic] webinar"
Body: Add one new detail not in Email 1 (a guest question you'll answer, a stat, a real scenario). This is where you convert the "I meant to register" crowd.

Email 3 — Day-of reminder
Subject line formula: "Today at [time]: [Topic]" or "We're live in [X] hours"
Body: Short and practical — the join link, what to have ready (their last BAS, their asset register, whatever's relevant), and a line telling them replay access is automatic if they can't make it live.

Email 4 — Replay + next step (sent within 24-48 hours after)
Subject line formula: "Missed it? Here's the replay: [Topic]" or "[Name], here's your recording + the 3 key takeaways"
Body: Link to the recording, three bullet takeaways for skimmers, and one clear call to action — book a 20-minute review, download the checklist mentioned in the webinar, or reply with a question. This email consistently outperforms the live attendance for actual booked calls.

Small accounting firm, first-ever webinar: A five-partner Gold Coast firm had never run a webinar before and was nervous about low attendance. Instead of a broad tax update, they ran "What Tradies Need to Know Before 30 June" — 30 minutes, four slides, one topic. They promoted it to their existing trade-industry client segment only, using the four-email sequence above. Forty-one registered, nineteen attended live, and the replay email generated seven discovery call bookings — more than double what a general newsletter send had ever produced.

Bookkeeping-plus-advisory firm: Rather than a compliance topic, this firm ran a cash flow forecasting webinar aimed specifically at hospitality clients heading into a quieter trading period, titled "Cash Flow Planning for Hospitality Businesses Before the Slow Season." Because the topic was narrow and the audience was pre-segmented from their CRM, open rates on the save-the-date email hit 52% — well above their usual 24% newsletter average — because the subject line spoke directly to a problem those clients were actually having.

SMSF specialist practice: With contribution cap changes landing, this practice ran "Contribution Cap Changes: What SMSF Trustees Need to Do Before 30 June." Because SMSF trustees are typically older and less likely to attend live webinars during work hours, the firm leaned hard into the replay email — worded as "Couldn't make it live? Here's your 20-minute recording plus the checklist" — which ended up driving more meeting bookings than the live session did.

How it actually works

Pick the platform to match the audience — Zoom Webinar or Microsoft Teams both work; the platform matters far less than the topic and promotion.
Timing: Tuesday to Thursday, midday, 30-45 minutes including Q&A, works best for busy professional-service audiences. Avoid Mondays and Fridays.
Segment your list before you send — a generic "all clients" blast performs worse than a targeted send to the 200 people the topic is actually relevant to.
Registration page should have one headline, three bullet points on what they'll learn, and nothing else. No navigation menu, no distractions.
Follow-up call within 48 hours of the replay email for anyone who clicked the CTA — the webinar warms them up, the phone call closes the loop.

💡 Your replay email is doing more work than your live event. Firms consistently see more booked calls from the replay send than from the webinar itself — treat that fourth email as seriously as the presentation, not as a courtesy afterthought.

Mistakes to avoid

Naming the webinar after a tax category instead of a specific client problem or deadline.
Sending only one promotional email and being surprised by low turnout.
Inviting your entire database instead of the segment the topic actually suits.
Skipping the replay email because "not many people asked for it" — most people won't ask, they'll just appreciate it landing.
Ending the webinar with no clear next step — "any questions, let us know" is not a call to action.

Frequently asked questions

How many registrations do we need for a webinar to be "worth it"?

There's no universal number — it depends on your client base size and the value of a single new engagement. A firm with 300 clients getting 40 registrations and 4 booked calls from a niche topic has done well; a firm chasing 500 registrations from a broad audience with no follow-up plan has not, even if the number looks bigger.

Should we run it live or just record a video and skip the "event" entirely?

Honest nuance: live events create urgency and higher promotion open rates because there's a real date attached, but a well-produced on-demand video with the same content can work for firms without the internal capacity to host live. What you lose is the live Q&A, which is often where the best rapport-building happens.

What if attendance is low on the day?

Don't panic and don't cancel. A small, engaged group of eight to ten people who ask real questions is more valuable than a large silent audience, and the recording still has a full second life through the replay email regardless of how many attended live.

How far in advance should we start promoting?

Three weeks is a reasonable default for most professional services audiences. Much earlier and people forget; much later and you don't get enough reminder touchpoints in before the date.
