How Do You Compare Actual Performance With Your Accounting Practice Acquisition Forecast?
Compare acquisition performance with the forecast by matching periods, separating earnings from cash and investigating what each difference tells you about the practice.
An accounting practice acquisition forecast becomes more useful after settlement, when you can test its assumptions against real client work, staffing costs and collections. The first results may be reassuring, uncomfortable or simply incomplete. Your task is to understand the explanation before deciding whether the original plan still holds.
For an Australian buyer, the first 100 days offer an early review window rather than a final verdict. Some annual engagements will not yet have come through the workflow, while transition spending may be concentrated at the beginning. A sensible comparison recognises both realities without allowing them to excuse every disappointing result.
The short answer
Keep a dated copy of the acquisition forecast and its supporting assumptions.
Compare actual results for the same period and on the same accounting basis.
Review revenue, invoices and cash receipts separately.
Investigate timing differences, one-off items and lasting changes.
Update the forward forecast and assign practical responses to material findings.
Start with the accounting practice acquisition forecast you actually relied on
Recover the version used when you made the purchase decision, including changes arising from due diligence. Identify its assumptions about retained fees, vendor involvement, staff costs, your own role and integration savings. If several versions circulated, agree which one represents the final acquisition case.
The sale presentation alone is insufficient for this purpose. Our explanation of an accounting practice Information Memorandum distinguishes the information presented by the vendor from the questions a buyer still needs to test. Now that you own the practice, the comparison should use your supported operating assumptions.
Preserve the original case when updating expectations. business.gov.au distinguishes a budget, which describes the financial plan, from a forecast, which estimates likely results using current information. Keeping both lets you see how the acquisition has changed rather than quietly replacing the evidence of your original expectations.
Make the periods genuinely comparable
If settlement occurred partway through a month, a full-month forecast cannot be compared directly with two weeks of ownership.
Prepare a comparison for the actual ownership period, with a clear treatment of costs that fall unevenly. The same discipline applies to billing cycles, public holidays and staff leave.
Avoid assuming annual revenue arrives in twelve equal instalments. Review the practice’s historical monthly pattern and the work scheduled for the months you now own it. A compliance-heavy practice may have quite different peaks from one built around monthly advisory packages. Our seasonal cash-flow discussion explains why the timing of trading and commitments deserves separate attention.
You should also reconcile reporting methods. Check whether comparable figures include GST, use the same revenue-recognition approach and classify staff, contractor and owner costs consistently. Where the acquired practice is joining an existing firm, retain enough reporting detail to distinguish acquisition performance from unrelated changes elsewhere.
Follow revenue through to invoicing and cash
A completed engagement, an issued invoice and a receipt are related events, but they answer different questions.
Revenue indicates financial performance under the applicable accounting treatment. Billing shows what has been invoiced. Collections show money received. You need to understand all three rather than select whichever measure looks strongest.
For example, work may continue at the expected level while invoices wait for partner approval.
Alternatively, invoices may be issued on schedule but remain unpaid because clients are querying the new payment instructions. Both situations can create a cash gap, although neither automatically establishes that the recurring fee base has fallen.
Check debtor movements, credits, write-offs and WIP alongside the revenue report. The purchase arrangements may allocate some pre-settlement balances to the vendor. Our guide to debtors and WIP explains why ownership and collection responsibilities matter, while the profit-versus-cash-flow article shows why reported earnings alone cannot establish payment capacity.
Ask whether the difference will reverse or persist
The useful question is what must happen for a shortfall to recover. Business Queensland distinguishes timing variances from emerging permanent changes when reviewing forecasts.
In an acquisition, a delayed engagement may shift revenue into a later month, whereas a confirmed client departure removes work that should no longer remain in the base case.
Ask the responsible team member for evidence. A revised delivery date, client instructions or agreed payment arrangement can support a timing explanation. “The client usually comes back” is weaker evidence if nobody has confirmed the work. Keep uncertain matters visible and consider a downside case rather than promising a catch-up.
A positive variance also deserves scrutiny. An unexpected one-off advisory assignment may improve this month without lifting recurring earnings. Similarly, lower staffing costs may reflect a vacant position while unfinished work accumulates. A favourable number can conceal a capacity problem that becomes more expensive later.
An illustrative comparison: one shortfall, several explanations
Assume the first comparable month forecast $100,000 of revenue and $90,000 of receipts. Actual revenue is $88,000 and receipts are $70,000. (These hypothetical figures do not describe any real client or benchmark.)
Suppose $8,000 of expected revenue relates to an engagement rescheduled into the next month, while $4,000 relates to a client who has confirmed departure. The buyer would investigate the rescheduled work and revise the ongoing fee assumption for the departure.
Separately, the $20,000 receipt gap requires a collections reconciliation because revenue movements alone do not explain it.
If $6,000 of unplanned migration spending also occurred, the buyer should show it as a transition item and include its cash effect. That makes the operating comparison clearer without pretending the payment did not happen. Each finding then needs its own response and expected completion date.
Turn the review into a current operating plan
Your review should cover staff and contractor costs, vendor assistance, premises, software and administration as well as fees.
Compare any proposed savings with the costs actually required to deliver the work. Include the time you are contributing, particularly if the forecast assumed the vendor’s responsibilities could be absorbed without replacement support.
business.gov.au recommends reviewing the main financial documents together when assessing financial health. Use the profit and loss statement, balance sheet and cash records to cross-check the explanation, rather than relying on a single dashboard total.
Update expected receipts and payments once the evidence changes. business.gov.au’s cash-flow statement guidance highlights payment cycles and seasonal patterns.
A rolling weekly view can supplement the monthly performance review when near-term cash is sensitive. Our 13-week cash-flow forecast guide explains how to preserve previous estimates and reconcile actual movements.
For each material variance, record the amount, cause, evidence, revised assumption and person responsible for responding. Agree a review date that matches the urgency. If working-capital needs or repayment capacity have changed, raise the finance implications with Fairlane early. A revised forecast informs that discussion but does not establish approval for additional funding.
Frequently asked questions
Should I replace the original forecast with actual results?
Keep the original version and prepare a current forecast separately. This preserves the purchase assumptions while giving you a practical view of what may happen next.
Does a poor first month mean the acquisition has failed?
No. A first-month result requires explanation in its context. Timing, transition costs and lasting changes have different implications, so investigate before drawing a broader conclusion.
Can I annualise the first 100 days?
Treat that approach cautiously because it may miss annual engagements and seasonal costs. Use the historical work pattern and current client evidence to assess the remaining period.
How much variance is acceptable?
There is no universal threshold. Consider the size, duration and cause of the difference, together with cash headroom, service capacity and relevant contractual finance obligations.
Let the evidence change the plan
A useful comparison ends with a better decision. Establish what remains supported, identify what is still uncertain and adjust the operating plan where the evidence warrants it. The aim is to understand the practice you now own well enough to act before a manageable difference becomes a larger problem.
Has Your Funding Position Changed After Acquisition?
If your review identifies a change in cash flow, working capital or the funding arrangements, we can help clarify the implications and discuss options.
