Fixed-Fee Pricing for CPA Practices Using Offshore Bookkeeping — Australian Guide

Why Fixed-Fee Works Better Than Hourly for Offshore Bookkeeping

Hourly billing on bookkeeping creates two problems when you introduce offshore production. First, if the Indian team completes a reconciliation in 4 hours that previously took 8, the client sees a smaller invoice — your efficiency gain becomes their saving, not yours. Second, hourly billing forces you to explain and justify every hour, which draws attention to who is doing the work and creates questions you would rather not answer.

Fixed-fee pricing solves both problems. The client agrees to a monthly fee based on the service scope — not on the hours consumed. Your input cost is irrelevant to the price. If the Indian team's efficiency improves over time, that improvement goes directly to your margin.

Fixed-fee also creates predictable cash flow for both parties. Clients can budget their bookkeeping costs with certainty. Your practice sees consistent monthly revenue rather than variable invoices that depend on how complex last month's transactions were. For a practice using offshore production, this predictability is particularly valuable — the Indian team's cost is already fixed, and so your revenue should be too.

See our related guide on pricing offshore bookkeeping for clients for the broader pricing strategy framework. This article focuses specifically on building and managing the fixed-fee structure itself.

Building Your Fixed-Fee Service Menu — Three Tiers

Most Australian CPA practices using offshore bookkeeping settle on three service tiers. The tiers are defined by transaction volume and included services, not by business size or revenue — a micro-business with high transaction complexity may sit in a higher tier than a medium business with straightforward accounts.

These are starting points — your practice's specific client base and local market rates will determine the exact pricing. The margin percentage holds regardless of the absolute price: the key is that your client price is roughly double your Indian CA cost across all tiers.

Add-on services charged separately rather than absorbed into tiers:

• Additional employees beyond the tier headcount — A$25–$40 per employee per month
• Additional bank accounts — A$30–$50 per account per month
• Trust accounting (separate entity) — A$200–$350 per month add-on
• TPAR preparation — A$150–$250 once per year
• Payroll tax return preparation — A$100–$200 per state per month

What to Include and Exclude in Each Tier

The scope definition in your engagement letter is the most important document in a fixed-fee arrangement. Vague scope creates scope creep. Precise scope means every variation is a clear, chargeable add-on.

Always include explicitly:

• Number of bank accounts covered (not "all accounts" — specify the number)
• Number of payroll employees (at time of engagement)
• Transaction volume cap (monthly transaction count — this is your cost driver)
• Number of entities covered (if the client has multiple companies or trusts, specify which are included)
• BAS frequency (monthly or quarterly — different workload profiles)
• What "BAS workpapers" means — reconciled accounts delivered to you for lodgement, not the lodgement itself (unless you have included it)

Always exclude explicitly:

• Tax return preparation (annual engagement, priced separately)
• Entities not listed in the scope — a second business the client starts during the year
• Payroll tax returns (state-level obligation, priced as an add-on)
• TPAR preparation (annual, priced as an add-on)
• Advisory work — answering client questions about tax planning, structure, depreciation strategy. Bookkeeping is data; advice is a separate service.
• Catch-up work for prior periods — if the client has 6 months of unreconciled accounts when you onboard them, this is a one-time project, not part of the ongoing fee

Handling Scope Creep — The Most Common Fixed-Fee Problem

Scope creep is inevitable in fixed-fee bookkeeping. Clients grow, hire more staff, open new accounts, and expand into new activities — often without thinking about the impact on their bookkeeping fee. The solution is not to absorb the extra work silently (destroying your margin) or to surprise the client with an unexpected invoice (destroying trust). The solution is a transparent variation process built into the engagement from day one.

The most common scope creep triggers and how to handle each:

• Payroll headcount grows: Build a clause into the engagement letter that states payroll for more than the agreed number of employees is billed at A$X per additional employee per month. When headcount grows, send a brief email confirmation: "Your payroll has grown to 8 employees — per our engagement terms, this adds A$75/month from this month. Let me know if you have any questions." No confrontation, no negotiation — it is already agreed.
• New bank account or entity added: Same approach — pre-agreed add-on price in the letter, brief email confirmation when triggered.
• Transaction volume consistently exceeds the tier cap: Review every 6 months. If a client has been consistently above the Standard tier threshold for 3+ months, move them to Comprehensive at the next review. Frame it as a tier upgrade, not a price rise.
• Client asks questions that cross into advice: "I have a question about whether I should buy or lease the new equipment" is not bookkeeping. Have a brief, friendly script: "That is a great question — it falls outside your bookkeeping scope but I would be happy to schedule a 30-minute advisory call at my standard hourly rate of A$X. Want me to book that?" This converts scope creep into advisory revenue.

Transitioning Existing Hourly Clients to Fixed Fee

Most practices already have bookkeeping clients on hourly billing. Transitioning them to fixed fee requires a short data analysis and a confident conversation.

1. Pull 6 months of time records for each client. Calculate the average monthly hours and the average monthly invoice. Identify peak months (BAS quarters) and trough months.
2. Set the fixed fee at the 65th–75th percentile month. Not the average (too low — you will lose money in busy months) and not the maximum (too high — client rejects it). The 65th–75th percentile covers most months without over-charging in slow months.
3. Check against your tier structure. If the client's calculated fixed fee falls between tiers, round up to the higher tier and confirm that the tier's scope matches what you are actually providing. This is also a good opportunity to make the scope explicit for the first time — many hourly clients have never had their bookkeeping scope formally defined.
4. Have the conversation proactively, not reactively. Frame it as a client benefit: "I am moving all our bookkeeping clients to fixed monthly pricing this quarter. For you, that means A$X/month — the same services you have now, with no invoice surprises in busy months. I will send you an updated engagement letter this week."
5. Give 30 days notice. Not 7 days. Not 60 days. 30 days is the professional standard and gives the client time to plan. In most cases, the response is acceptance with no discussion.

Annual Price Review — Building It into the Engagement Letter

A fixed fee without a review mechanism is a liability. Clients grow, inflation rises, and the Indian CA firm's cost will eventually increase. Without a pre-agreed review clause, every price increase becomes a negotiation — uncomfortable and avoidable.

Include this clause (or equivalent) in every engagement letter:

"This fee is reviewed annually on [month] each year. The review takes into account changes in scope, transaction volume, inflation, and cost adjustments from our service providers. You will receive 30 days written notice of any fee change. If your business activity changes materially during the year (new payroll employees, additional entities, significant change in transaction volume), we may review the fee at the time of the change in addition to the annual review."

Apply CPI increases at a minimum each year — even if your Indian CA costs have not risen. This keeps the fee current with the market, prevents the client from anchoring to an increasingly stale price, and means that when a larger increase is needed, it is a smaller jump rather than a multi-year correction applied all at once.

For practices using the dedicated Indian accountant model, the annual Indian CA cost is fixed for the financial year — giving you full visibility into your margin when setting the annual client price review.
