Engagement Letters: A Growth Tool, Not Just a Legal Requirement
Many firms view engagement letters as a compliance necessity—a document that simply outlines scope and protects against risk. While that’s true, they can be much more. A well-crafted engagement letter is a powerful client selection and business growth tool that ensures you’re working with the right clients, setting profitable expectations, and opening doors for future opportunities.
Here’s how to rethink engagement letters to win better clients and build stronger relationships.
1. Use Engagement Letters to Filter Out the Wrong Clients
Not all clients are a good fit for your firm. The wrong clients—those who don’t value your time, resist your processes, or delay payments—can cost you money and create unnecessary stress.
The Fix: Use engagement letters to set clear boundaries and expectations early. If a client pushes back, it’s a red flag they may not be the right fit.
Key Clauses to Include:
- Turnaround Times: Define how quickly you expect documents and responses from clients.
- Payment Terms: Clearly outline payment expectations and late fees.
- Scope Clarity: Detail what’s included in the engagement—and what isn’t—to avoid scope creep.
2. Position Your Value, Not Just Your Services
Most engagement letters read like a dry list of services. Instead, position your firm’s value by framing your engagement letter as a strategic agreement that benefits the client.
The Fix: Rewrite key sections to emphasize the outcomes and benefits of working with your firm.
Example: Before vs. After
❌ We will prepare and lodge your tax return.
✅ We will ensure your tax compliance is streamlined, reducing your tax burden and minimizing ATO risk.
This slight tweak transforms a service list into a value-driven promise.
3. Upsell & Introduce Advisory Services Within the Engagement Letter
Your engagement letter shouldn’t just outline what you’re already doing—it should also hint at what else you can do.
The Fix: Include an “Additional Services” section that encourages clients to discuss future needs.
Example:
- Beyond compliance, we offer cash flow forecasting, business growth consulting, and tax planning. If you’d like to discuss how we can help you beyond standard compliance, let us know!
- Many clients find value in quarterly check-ins to proactively manage tax obligations. Would you like to add this to your engagement?
By doing this, you plant the seed for additional revenue opportunities.
4. Set Boundaries to Avoid Scope Creep & Last-Minute Fire Drills
One of the biggest reasons firms lose profit is because clients expect extra work beyond the agreed scope—without additional fees.
The Fix: Your engagement letter should define what happens when additional work is required.
Key Phrases to Add:
- Any work beyond the agreed scope will be quoted separately before commencement.
- Urgent work requests outside of agreed turnaround times may incur a priority processing fee.
These boundaries help protect your time and profitability while keeping client relationships intact.
5. Automate & Customize Engagement Letters for Different Client Types
Not all clients require the same level of detail or service. Your engagement letter process should be tailored to different client types and streamlined using automation.
The Fix: Use a tool like Seamlss to create dynamic engagement letter templates that adjust based on client needs.
How Automation Helps:
- Pre-built templates for different service levels (e.g., compliance-only vs. advisory clients).
- Seamless updates when engagement terms change.
Conclusion: Engagement Letters Are a Business Growth Strategy
A strong engagement letter does more than protect your firm—it positions your value, sets boundaries, and opens the door for future revenue.
Next Step: Review your current engagement letter. Does it:
- Filter out bad-fit clients?
- Emphasize value over services?
- Introduce upselling opportunities?
- Protect against scope creep?
If not, it’s time for an upgrade.
