Accountant Engagement Letters For Advisory Services

Expanding your accounting practice into advisory work can be exciting. You might be helping clients understand their numbers, plan cash flow, prepare management reports or think through a difficult trading period.

It can also feel like the risk level jumps overnight. A routine tax return is one thing. A cash flow forecast that a client relies on to make staffing, lending or restructuring decisions is very different.

Your engagement letter is where you set the rules clearly from the start. When it's written well, it helps your client understand what you're doing, what you aren't doing, and where their own responsibilities begin.

What Is An Accountant Engagement Letter For Advisory Services?

An accountant engagement letter for advisory services is a written service agreement that sets out the advisory work you'll provide, how the client can use it, what information you need, your fees and the limits of your responsibility.

For advisory work, your engagement letter usually needs to go further than standard accountant terms of engagement in New Zealand. This is because advisory work often involves judgement, assumptions and business decisions that sit outside ordinary compliance work.

For example, your advisory services may include:

• cash flow forecasting
• management reporting and dashboard preparation
• budgeting and variance analysis
• business performance reviews
• restructuring support from a financial information perspective
• KPI tracking and board reporting packs
• financial modelling for funding discussions
• general business advisory meetings

Those services can be incredibly valuable to clients. But they can also create misunderstandings if the client assumes your forecast is a guarantee, your management report is an audit, or your restructuring support means you're giving legal or insolvency advice.

A good business advisory engagement letter closes that gap early.

Do You Need Separate Terms For Advisory Work?

Yes, you should usually have separate or additional terms for advisory work because the scope, reliance risk and client expectations are different from routine accounting or tax services.

You may already have standard accounting services agreement terms or a wider terms of engagement package covering annual accounts, GST, income tax returns or payroll assistance. Those terms may work well for repeat compliance tasks, but they often don't deal properly with advisory risk.

Advisory work can involve:

• forward-looking information, not just historical numbers
• commercial recommendations, not just calculations
• reports shared with directors, lenders or investors
• urgent decisions during a cash flow squeeze
• information supplied by the client that you haven't independently verified

Say you advise Kauri Cafe Limited, a Wellington cafe group, on a 13-week cash flow forecast. The directors use your model when deciding whether to reduce opening hours, speak to their bank or delay supplier payments. If the forecast later turns out to be wrong because sales assumptions were too optimistic, you want your engagement letter to make clear who provided those assumptions and what level of checking you agreed to do.

That doesn't mean you can contract out of every responsibility. If you provide professional services, you still need to take reasonable care and avoid misleading your client. But your terms can reduce confusion and make the agreed boundaries much easier to prove.

What Should Your Scope Of Accounting Services Cover?

Your scope should clearly describe the exact advisory services you'll provide, the deliverables the client will receive and the services that are excluded.

The scope of accounting services is often the most important part of the engagement letter. It's also the part that causes the most problems when it's too broad.

Describe The Work In Practical Terms

Instead of saying you'll provide business advisory services, be specific. For example, your scope might say you will:

• prepare a monthly management report using Xero data supplied by the client
• prepare a 13-week cash flow forecast based on assumptions agreed with the client
• attend one monthly advisory meeting of up to 90 minutes
• review budget versus actual performance and identify key variances
• prepare a board reporting pack for internal management use

You should also say what format the deliverables will take. For example, a spreadsheet model, PDF report, dashboard, email summary or meeting notes.

List What Is Not Included

Exclusions aren't negative. They protect the relationship because they stop the client assuming you're doing work you haven't priced or agreed to do.

For higher-risk advisory work, common exclusions include:

• audit, review or assurance services
• legal advice on directors duties, insolvency or restructuring options
• tax advice beyond the specific work described
• investment, financial product or lending advice
• business valuations for sale or purchase purposes
• verification of information supplied by the client or third parties
• negotiations with banks, creditors or investors unless specifically agreed

If a client needs specialist legal, insolvency, tax or financial advice, your terms can say they should get that advice from the right professional. That keeps your role clear and helps you avoid drifting into areas you aren't engaged to cover.

Set Timeframes And Review Points

Your engagement letter should also explain when work starts, how often reports are prepared and when the scope will be reviewed.

For example, a cash flow advisory engagement might run for three months and then renew monthly. A management reporting engagement might continue until either party ends it on 30 days notice. The right setup depends on how your practice works and how much flexibility you want.

How Should You Deal With Forecasts, Assumptions And Reliance?

You should deal with forecasts by recording the assumptions, stating who is responsible for them and explaining that forecasts aren't guarantees of future performance.

This is especially important for cash flow forecasting, restructuring support and financial modelling. Forecasts are built on assumptions about future sales, costs, margins, wages, lending, payment timing and customer behaviour. Even careful forecasts can change quickly.

Your engagement letter should cover:

• which assumptions the client must provide or approve
• whether you'll test, challenge or simply record those assumptions
• the date the forecast is prepared and the period it covers
• how often the forecast will be updated
• the purpose of the forecast
• who can rely on the forecast
• what the client must not use the forecast for without your written agreement

For example, if you prepare a cash flow forecast for internal management planning, the client shouldn't send it to a lender as if it were an independent assurance report unless you have agreed to that use.

This matters under the Fair Trading Act 1986 because businesses must not engage in misleading or deceptive conduct in trade. Your client may also be relying on your work when making statements to banks, suppliers or investors. Clear reliance wording helps everyone understand what the report does and doesn't say.

It can also be useful to include a third party reliance clause. This might say your work is prepared only for the named client and for the purpose described in the engagement letter. If another person wants to rely on it, you can require a separate written agreement first.

What Liability And Responsibility Clauses Should You Include?

Your engagement letter should include responsibility clauses covering client information, your standard of care, liability limits, exclusions and the consequences of inaccurate or incomplete information.

These clauses need to be fair and carefully drafted. Overly aggressive clauses can damage trust, and in some cases may not be enforceable. But leaving them out can expose your practice to claims that were never priced into the work.

Client Information And Decisions

Your client should be responsible for providing accurate, complete and timely information. This includes accounting records, payroll data, debtor and creditor information, bank balances, loan details and commercial assumptions.

Your terms should also say the client remains responsible for business decisions. You can provide analysis and recommendations, but the directors or owners decide what action to take.

This is particularly relevant for companies. Under the Companies Act 1993, directors have duties around acting in good faith, exercising care and diligence, and not allowing the company to trade recklessly or incur obligations it can't perform. Your role shouldn't be written in a way that suggests you're taking over those director responsibilities.

Standard Of Care

Your engagement letter can say you'll perform the services with reasonable care and skill. That wording reflects the practical standard clients expect and helps avoid unrealistic promises.

Be careful with language like guarantee, certify, ensure or confirm unless you truly mean it. Those words can lift client expectations and make a practical advisory report sound like an assurance engagement.

Limiting Liability

Many accounting practices include a limitation of liability clause. This might cap liability at a set dollar amount, a multiple of fees paid, or the amount recoverable under your professional indemnity insurance.

The right cap depends on your services, client type, fee level, insurance and professional obligations. You should get tailored advice before relying on a liability cap, especially for high-value advisory work.

If your client is acquiring your services in trade, the Consumer Guarantees Act 1993 may allow you to contract out of some guarantees if the agreement is in writing, both parties are in trade and the term is fair and reasonable. That needs to be handled properly in your terms.

What Terms Should Cover Fees, Changes And Client Information?

Your terms should explain how fees are calculated, what happens when the scope changes, when invoices are due and what the client must provide so you can do the work.

Advisory work can expand quickly. A monthly reporting engagement can turn into extra board papers or an ongoing advisory agreement. A cash flow model can turn into multiple scenario plans. Restructuring support can become urgent daily calls.

Your engagement letter should cover:

• whether fees are fixed, hourly, monthly retainer or project-based
• what is included in the fee
• what counts as out-of-scope work
• how you'll quote or approve extra work
• invoice timing and payment due dates
• whether you can pause work if invoices are unpaid
• how either party can end the engagement

Without a written agreement, you may struggle to recover unpaid invoices or justify charging for extra work that the client assumed was included.

You should also set practical client obligations. For example, the client may need to provide bank feeds, reconciled accounts, aged receivables and payables, payroll reports and inventory information by a certain date each month.

If your work depends on live accounting software, your terms can say you aren't responsible for errors caused by missing data, incorrect coding, unreconciled accounts or unauthorised changes made after you prepare a report.

How Do Privacy, Confidentiality And IP Work For Advisory Services?

Your engagement letter should protect client confidentiality, deal with personal information under the Privacy Act 2020 and explain who owns or can use your reports, models and templates.

Advisory work often gives you access to sensitive information, including payroll records, customer lists, supplier pricing, loan documents, profit margins and restructuring plans. Your client will expect that information to be kept confidential.

Your confidentiality clause should cover:

• what information is confidential under your confidentiality terms
• when you can disclose information, such as to your staff, contractors, software providers or regulators
• how long confidentiality lasts
• what happens if disclosure is required by law

If you collect or handle personal information, the Privacy Act 2020 may apply. You should think about how you collect, store, use and share personal information, particularly if you use cloud accounting tools, online service terms, offshore software providers or outsourced support.

If there's a notifiable privacy breach, the Privacy Act 2020 requires notification to the Privacy Commissioner as soon as practicable after becoming aware that a notifiable breach has occurred. Affected individuals must also be notified as soon as practicable, unless an exception applies, a permitted delay applies, or public notice is required instead. Your internal process should support that, and your engagement terms shouldn't promise something your systems can't deliver.

IP is also worth covering. You may create reports, spreadsheet models, dashboard formats, processes and templates. Your terms can say the client can use the final deliverables for the agreed purpose, while you retain ownership of your underlying know-how, templates and methods.

This is one area where generic templates often miss the commercial detail. Your documents will work best when they match the way your practice actually delivers advisory services.

Common Mistakes To Avoid

The most common mistake is using a standard compliance engagement letter for higher-risk advisory services and hoping it will cover everything.

Other mistakes include:

• Using vague scope wording: Phrases like business advice or general support can mean different things to different people.
• Forgetting reliance limits: If your report is for internal management use only, say that clearly.
• Not recording assumptions: Forecasts should show the key assumptions and who provided or approved them.
• Promising too much: Avoid wording that makes a forecast sound certain or a management report sound like an audit.
• Letting scope creep continue unchecked: Have a simple process for approving extra work and fees.
• Ignoring director responsibility: Your client should remain responsible for decisions, especially during financial difficulty.
• Leaving privacy and software out: Advisory work often involves cloud tools and sensitive personal information.

The aim isn't to make your engagement letter harsh. It's to make it clear enough that a sensible client knows exactly what they're getting and how to use it.

Key Takeaways

• Advisory services need clearer engagement terms than routine accounting or tax work because the client may rely on your judgement when making business decisions.
• Your scope should spell out the deliverables, timeframes, assumptions, exclusions and whether the work includes any assurance or verification.
• Cash flow forecasts, restructuring support and management reports should include careful wording about reliance, client information and future uncertainty.
• Your terms should address liability, fees, out-of-scope work, confidentiality, privacy and IP in a way that matches how your practice actually operates.
• New Zealand laws such as the Fair Trading Act 1986, Consumer Guarantees Act 1993, Companies Act 1993 and Privacy Act 2020 can all be relevant to advisory engagement terms.
